description: The modern world has a number of challenges. Climate change, rising radiation backgrounds, cancer, cardiovascular diseases, infections threaten the sustainable development of humanity. Today, as never before, it is time for scientists to work together to overcome these challenges. The spread of SARS-COV-2 virus has completely changed the biomedical research agenda. Multi-organ lesions caused by the virus require the analysis of knowledge and experience accumulated in various fields. One of the most serious factors causing multi-organ injuries is radiation. As studies show, pathologies obtained with covid-19 and high-dose radiation are very similar to each other. Determining the advantages of many years of experience and methods of radiation disease management for treatment of similar disorders caused by the SARS-COV-2 virus creates an excellent prospect for rescuing patients with moderate to severe symptoms. Inflammation is a major common player in COVID-19 and ARS (Acute Radiation Syndrome) and causes multiple systemic damage. Both cause cytokine storms, the number of pro-inflammatory cytokines increases, and the number of anti-inflammatory cytokines decreases. Both COVID-19 and radiation exposure result in systemic damage of the vascular system, lungs, heart, kidneys, liver, intestines, eyes, and brain. Regardless of the target organ, the management of immunogenic pathway hyperactivity is a major target for overcoming COVID-19and acute radiation exposure. The goal of presented review is to underline some ofthe similarities of multisystem damages caused by Covid-19 infection and ARS. A long-term and diversified study of ARS has identified the main targets of radiation exposure and developed ARS medical management strategies that can be successfully adapted to manage systemic lesions in patients with COVID-19.

Year: 2021

description: Results of investigation of connection of sum light aeroions concentration (N) with environmental gamma radiation (Γ) and air temperature (T) in western Georgia are presented.Simultaneous measurements of N, Γ and T were madeat 166 different points by using portable aeroions, gamma and temperature survey meters.The terrain height (H) varied from 6 to 1928 m above sea level.The statistical characteristics of the values ofN, Г and Thave been studied. In particular, the following results were obtained. Range of changes of investigation parameters is following: N – 450÷3100 sm-3, Γ - 40÷180 nSv/h, T - 10÷34 ˚C. Mean values: N –1898 sm-3, Γ - 80 nSv/h, T – 24.6 ˚C.Coefficient of linear correlation (R) of individual values of N with Г, T and H accordingly are: 0.08 (level of signification α=0.25), 0.30 (α<0.005) and 0.12 (α=0.10). It is absent correlation between Г and T.A multiple linear regression equation N with Г, T and H is obtained. In particular, the variability of the individual N values with the variability of other studied parameters within the variation range is as follows (166 different pointsof measurements): Г–6.9 %, T – 61.0 % and H – 47.1 %. Thus, the main factor in the variability of the content of light air ions in this case is not the ionizing effect of gamma radiation from the soil, but the air temperature (variability of radon emanation from the soil) and the height of the terrain (variability of cosmic radiation). Connection of the averaged values of N on the Г has the form of a linear function: N = 2.9228·Γ + 1671.2 (R = 0.96, α<0.005).

Asheville, North Carolina: U.S. Department of Agriculture, Forest Service, Southern Research Station. pp. 15-28.

Monitoring the occurrence of forest pest and pathogen outbreaks is important at regional scales because of the significant impact insects and disease can have on forest health across landscapes. Low-altitude survey data, collected, in 2010, by the Forest Health Protection Program of the Forest Service in 2010, identified 67 different mortality-causing agents on nearly 3.68 million ha of forest in the conterminous United States, and 70 defoliating agents on approximately 3.72 million ha. Significant large geographic hot spots of forest mortality were associated with mountain pine beetle in the West, while a smaller hot spot was associated with Ips engraver beetles in the South. Hot spots of defoliation were spread throughout the conterminous States, the largest and most intense associated with pinyon needle scale, western spruce budworm, forest tent caterpillar, and gypsy moth. Spruce beetle was the most important cause of mortality in Alaska, while willow leaf blotchminer and aspen leafminer were the most important defoliating agents.

description: Medical use of ionizing radiation is one of the most rapidly developing areas of radiationapplications. Although the access to the medical radiation technologies varies around the world, an important trend is the rapid introduction of new technologies and new techniques linked to the demand of improved diagnosis and treatment outcomes.The technological developments have led to reduction of some of the previously well-established risks, however, new risks emerged linked to the introduction of new modalities with higher doses, easier access to technologies, increased complexity of equipment, as well as the wider group of medical professionals using radiation imaging outside the traditional radiology profession and without proper radiation protection training. The challenges include justification of medical exposure, practical use of approaches for optimization, such as quality control, patient dosimetry, diagnostic reference levels, proper use of imaging in radiotherapy, all linked to the need of improved education and training of health professionals with different professions. Another important area is the need of improved safety culture and team approach to radiation protection, which compliments the safety standards and regulatory actions. Involvement of different key stakeholders is crucial for successful implementation of the international safety standards and recommendations in the medical applications of ionizing radiation.

description: Nowadays, more than the 90% of the companies in Mexico (IPADE 2000) are companies that belong to families; therefore, they play a dominant role in the economy. The goal of this investigation is to indicate which factors affect, in a differential way, the rural and urban family business at Dzidzantun municipality in Yucatan State. The study of four family's companies of the municipality of Dzidzantun will help to explain which factors affect the continuity in this type of companies. Among outstanding factors in the research appears the family cohesion, good communication among the family members and the lack of training. The results could let the entrepreneurs develop a new perspective about continuity in their business: a valuable family patrimony.
Dynamical phase transitions in dissipative quantum dynamics with quantum optical realization

Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study dynamical phase transitions (DPT) in the driven and damped Dicke model, realizable for example by a driven atomic ensemble collectively coupled to a damped cavity mode. These DPTs are characterized by non-analyticities of certain observables, primarily the overlap of time evolved and initial state. Even though the dynamics is dissipative, this phenomenon occurs for a wide range of parameters and no fine-tuning is required. Focusing on the state of the 'atoms' in the limit of a bad cavity, we are able to asymptotically evaluate an exact path integral representation of the relevant overlaps. The DPTs then arise by minimization of a certain action function, which is related to the large deviation theory of a classical stochastic process. From a more general viewpoint, in the considered system, non-analyticities emerge generically in a Fock space representation of the state. Finally, we present a scheme which allows a measurement of the DPT in a cavity-QED setup.

Asheville, North Carolina: U.S. Department of Agriculture, Forest Service, Southern Research Station. pp. 5-15.

Healthy ecosystems are those that are stable and sustainable, able to maintain their organization and autonomy over time while remaining resilient to stress (Costanza 1992). Healthy forests are vital to our future (Edmonds and others 2011). The Forest Health Monitoring (FHM) Program of the Forest Service, U.S. Department of Agriculture, with cooperating researchers within and outside the Forest Service and with State partners, quantifies the health of U.S. forests. The analyses and results outlined in sections 1 and 2 of this FHM annual national technical report offer a snapshot of the current condition of U.S. forests from a national or multi-State regional perspective, incorporating baseline investigations of forest ecosystem health, examinations of change over time in forest health metrics, and assessments of developing threats to forest stability and sustainability. For datasets collected on an annual basis, analyses are presented from 2011 data. For datasets collected over several years, analyses are presented at a longer temporal scale. Chapters describe new techniques for analyzing forest health data as well as new applications of established techniques. Finally, section 3 of this report presents summaries of results from recently completed Evaluation Monitoring (EM) projects that have been funded through the FHM national program to determine the extent, severity and/or causes of specific forest health problems (FHM 2012).
Modeling of cell signaling pathways in macrophages by semantic networks
Creators: name: Hsing, Michael
Publisher: name: University of British Columbia
Year: 2009

description: Macrophages are essential components of human immune system that engulf and digest pathogens using the molecular mechanisms of phagocytosis and phagosome maturation. These processes are regulated by an essential enzyme - phosphoinositide-3-kinase (PI3K), a key initiator of signalling cascades in many cellular processes. Importantly, experimental studies demonstrate that some pathogenic bacteria, such as Mycobacterium tuberculosis (MTB), can interfere with PI3K pathways in order to survive within host macrophages. Based on the diverse roles of PI3Ks, it is reasonable to hypothesize that MTB effects upon PI3K signaling could impact macrophages in numerous ways, more than what are currently studied. It is anticipated that greater understanding of PBK signaling mechanisms in macrophages and bacterial interference could provide insights for developing effective strategies against MTB. The complexity of POK pathways makes the analysis of MTB-macrophage interactions a challenging task. Although a vast amount of knowledge on the pathways has been accumulated in literature and databases, the information is encoded in static diagrams that are difficult to study. While it is necessary to analyze complex systems computationally, the tools for modeling pathways are inadequate. To address current limitation on pathway manipulation, we applied an artificial intelligence method called Semantic Networks (SN) to model MTB interference with PI3K signalling pathways in macrophages. The advantage of SN is in its capacity to represent abstract concepts in machine friendly formats termed "semantic agents" and "relationships". In SN, the behaviour of agents is not fixed, but instead emerges from their relationships. This characteristic makes SN well suited for modeling biological systems. Using the SN methods, a model has been created to describe PI3K participation in macrophage signaling. The model encompassed a large amount of information extracted from scientific literature and pertained such complex micro-events as formation of protein complexes, chemical modifications of proteins, allosteric regulation, and changes in intracellular localization by the agents. The data integration in the SN-environment allowed us to reconstruct the molecular mechanisms of macrophage pathogenic invasion, and the model predicted previously unobserved macrophage responses. The results will be used to guide and interpret upcoming gene and protein expression studies.
Phase field-based electro-chemo-mechanical models for predicting interface degradation in solid-state batteries
Creators: name: Wang, Runzi
Publisher: name: Imperial College London
Year: 2024

description: All-solid-state lithium metal batteries (ASSLBs) are considered the next-generation electrochemical energy storage solution, potentially replacing conventional liquid-state lithium-ion batteries (LSLBs) due to their theoretically higher energy and power densities, as well as their enhanced safety. However, challenges such as low electrolyte ionic conductivity and dendrite formation still hinder their widespread application. While significant breakthroughs have been achieved in enhancing solid electrolyte materials, limited efforts have been dedicated to developing finite-element models that address these challenges through multi-physics couplings. This research aims to propose a mechanistic theory for predicting interface stability in ASSLBs involving the evolution of voids in Li metal electrodes during charging and discharging. A phase-field formulation is developed to allow a dynamic tracking of the evolution of the void-lithium interface, coupled with a viscoplastic description of Li deformation that captures creep effects and incorporates mass transfer. The model also accounts for the interaction between the electrode and the solid electrolyte, predicting current distributions and local current 'hot spots' that precede dendrite formation. The evolution of voids and current hot spots is successfully predicted as a function of applied pressure, material properties, and dis/charge history. Key experimental observations are captured, including current density distribution in electrolyte and void morphology, sensitivity to applied current, the role of pressure in enhancing electrolyte-electrolyte contact, and the dominant role of creep on void diffusion. The results demonstrated the capability of the model to correctly predict the dynamic evolution of the interface morphology during battery cycles. However, through quantitative analysis, its limitations in high-pressure-related simulation are acknowledged. Despite these challenges, this model constitutes a novel contribution to this research field and offers insightful understandings for researchers through qualitative analysis.

description: This article investigates the effect of prices and socio-demographic variables on the farmers decision to purchase agricultural insurance. A survey has been conducted to 200 farmers most of whom are engaged in diversified income-generating activities. The logistic estimation results suggest that education and household income from farming activities positively affect the likelihood of purchasing insurance. The demand for insurance is negatively correlated with the premium paid per insured value, suggesting that insurance is a normal good. Farmers are willing to pay (WTP) increasingly higher premiums for contracts with a higher coverage ratio. According to the valuation model, the WTP declines sharply for coverage ratios under 70%.

Derived of the participation in the Rapid Assessment of Program Acquisition of Productive Assets : Component Protected Agriculture 2008, the characteristics and the context are approached in which the agriculture protected in Mexico is develops. The definition of “protected agriculture” settles down, their characteristics are described and the dynamics that has presented, as well as the climatic surroundings this activity is develops. Also is presented, in function of the risk of it, in which states this activity can be implemented. In addition, the phenomenon of the vulnerability with respect to the agriculture protected in Mexico is described. Finally, the factors that affect the impulse of the protected agriculture are described : the low level of the curve of learning of the interested ones; the fitosanitary uncertainty; the high investment of the greenhouses, the operation costs for temperature control and relative humidity, or the wrong design; the production scale. In favor of impelling the development of protected agriculture, one concludes that the greenhouses are a viable alternative to surpass the production generated in the smallholdings.

description: We study the interplay between spin-orbit coupling (SOC) and Coulomb repulsion in a Hubbard model on a decorated honeycomb lattice which leads to a plethora of phases. While a quantum spin hall insulator is stable at weak Coulomb repulsion and moderate SOC, a semimetallic phase emerges at large SOC in a broad range of Coulomb repulsion. This semimetallic phase has topological properties not observed in conventional metals such as a finite, non-quantized spin Hall conductivity. At large Coulomb repulsion and negligible spin-orbit coupling, electronic correlations stabilize a resonance valence bond (RVB) spin liquid state in contrast to the classical antiferromagnetic state predicted by mean-field theory. Under sufficiently strong SOC, such RVB state is transformed into a magnetic insulator consisting on S~3/2 localized moments on a honeycomb lattice with antiferromagnetic order and topological features.

description: At present companies are trying hard to reduce productive assets by reducing general expenses and increasing flexibility toward what they call “lean production”. For this reason they are hiring specialized companies under long term agreements in order to supply parts, operations, and services, with quality responsibility, integrating them into their production line with their own workers. Worldwide, a new phenomenon has occurred where technology has taken over a great deal of the company's performance through simplified processes. After which there has been the need to implement an integration phase, and finally there is a tendency towards optimization. Agribusiness is part of this new tendency. “Tercerización” is more known for its English term “outsourcing”. Nevertheless, “tercerización” is becoming a more and more familiar term. This is good for the Spanish Language as foreign expressions should be avoided. Currently this technique is applied in big agricultural and agribusiness corporations, however during research, it was determined that other companies, such as accounting offices, service companies, and food-analysis labs, are using something similar to what has been described.

Publisher: name: Radiobiology and Radiation Safety
Year: 2021

description: The article provides an overview of the development of radiation genetics in the Georgian medicine. It considers stages of introduction of genetic methods in the examination of persons exposed to different doses of ionizing radiation under different conditions. The results of chromosomal biodosimetry, introduced since 2000, have been summarized in persons who had received high and low doses as a result of accidents due to contact with abandoned, orphan radiation sources, as well as during professional contacts and in the process of radiation therapy. In addition to the results of chromosomal research, both in total irradiation in accidents as well as during radiotherapy, the importance of using methods for determination of micronuclei level in lymphocytes, buccal and erythroid cells, as well as, using the comet method, DNA damage for the purpose to assess the clinical state of irradiated subjects is being analyzed.

description: The paper discusses the risks caused by the use of biologically active additives in radiotherapy and diagnostics in terms of radiation safety. Their inclusion in the treatment methodology is an acute biomedical problem due to the unforeseen negative effects of their interaction with other pharmacological drugs. It has been concluded that insufficient study of the risks of using BAAs with different radiological methods can pose a serious threat to the patient’s health and life.

Structural and functional studies of the N-Terminal domain of the GABPα
Creators: name: Kang, Hyun-Seo
Publisher: name: University of British Columbia
Year: 2009

description: GA-binding protein (GABP) is a heterotetrameric αβ₂α transcription factor composed of two structurally dissimilar subunits, GABPα and GABPβ. The modular DNA-binding subunit, GABPα, was known previously to consist of a DNA-binding ETS domain and a PNT domain, which presumably mediates protein-protein interactions with other components of the signalling or transcription machinery. The transactivation subunit, GABPβ consists of three domains, namely the ankyrin repeats, which bind GABPα, a leucine zipper to form β₂ dimers, and a transactivation domain. GABP is known to regulate gene expression involved in many different cellular functions, such as cell cycle control, apoptosis, and viral pathogen expression. An investigation of the N-terminal region of GABPα revealed the existence of third structured domain. Using partial proteolysis and NMR spectroscopy, this new domain was localized to residues 35-121, and was found to be flanked by unstructured residues and independent of the adjacent PNT domain. The gene encoding this domain was cloned and expressed, yielding a new truncation fragment, GABPα³⁵⁻¹²¹. As a step towards discussing its function, the structure of GABPα³⁵⁻¹²¹ was determined by NMR spectroscopy. The protein is composed of a 5-stranded β-sheet crossed by a distorted helix. Although globally resembling ubiquitin, GABPα³⁵⁻¹²¹ adopts a novel fold as evident by the arrangement of its secondary structure elements. An analysis of GABPα³⁵⁻¹²¹ for features indicative of a macromolecular binding interface revealed only a region of negative charge. Therefore, the structure of GABPα³⁵⁻¹²¹ provides few clues to its function. To determine the function of GABPα³⁵⁻¹²¹, these strategies will be pursued based on the hypothesis that this domain is a protein-protein interaction module. First, potential interactions with other domains of GABPα and GABPβ will be examined using approaches such as native gel electrophoresis, chemical crosslinking, and NMR spectroscopy. Second, interactions of GABPα³⁵⁻¹²¹ with reported partners of GABP, such as ATF, CBP/p300, or Spl, will be tested. Finally, unbiased affinity methods will be used to identify proteins from cellular extracts that bind specifically to GABPα³⁵⁻¹²¹.

description: Monte Carlo simulations are increasingly used in scintigraphic imaging to model imaging systems and to develop and assess tomographic reconstruction algorithms and correction methods for improved image quantitation. GATE (GEANT 4 Application for Tomographic Emission) is a new Monte Carlo simulation platform based on GEANT4 dedicated to nuclear imaging applications. This paper describes the GATE simulation of a prototype of scintillation camera dedicated to small animal imaging and consisting of a CsI(Tl) crystal array coupled to a position sensitive photomultiplier tube. The relevance of GATE to model the camera prototype was assessed by comparing simulated 99mTc point spread functions, energy spectra, sensitivities, scatter fractions and image of a capillary phantom with the corresponding experimental measurements. Results showed an excellent agreement between simulated and experimental data: experimental spatial resolutions were predicted with an error less than 100 mu m. The difference between experimental and simulated system sensitivities for different source-to-collimator distances was within 2%. Simulated and experimental scatter fractions in a [98-182 keV] energy window differed by less than 2% for sources located in water. Simulated and experimental energy spectra agreed very well between 40 and 180 keV. These results demonstrate the ability and flexibility of GATE for simulating original detector designs. The main weakness of GATE concerns the long computation time it requires: this issue is currently under investigation by the GEANT4 and the GATE collaborations

description: The time evolution of a closed quantum system was described quite early in the history of quantum physics. These dynamics are reversible, and the time evolution is implemented by a continuous unitary group, which is in turn generated by a selfadjoint Hamiltonian operator. So, we have a complete mathematical characterization of all such evolutions. For open quantum systems the time evolution is given by dynamical semigroups. In the case of uniform continuity the generator of the dynamical semigroup is a bounded operator in the famous GKLS-form that has been found by V. Gorini, A. Kossakowski, G. Sudarshan and, independently, G. Lindblad. But the problem of characterizing also the merely strongly continuous dynamical semigroups or, equivalently, their unbounded generators, is open. In the first part of this thesis we introduce a standard formfor the generator of quantum dynamical semigroups that is an unbounded version of the GKLS-form. The basis of the standard form are so-called no-event semigroups, describing an evolution of a quantum system, that maps pure states to multiples of pure states, and completely positive perturbations of their generator that correspond to jumps in this evolution, like absorption by a measurement device. We will give examples of standard semigroups, which appear to be probability preserving to first order (i.e., when looking only at the generator on the finite-rank part of its domain) but not for finite times. Additionally, we construct examples of generators not of standard form by modifying the previous examples. In the second part we relate the notion of standardness toW. Arveson’s classification of endomorphism semigroups. He divided them into three classes, Type I, Type II and Type III. We show that a conservative dynamical semigroup is standard if and only if the minimal dilation of its adjoint is of Type I. The key feature is the set of ketbras in the domain of the no-event generator and whether it is a core for the standard generator. With this knowledge, we suggest to extend this classification to (not necessarily conservative) semigroups that are standard or can be constructed as a series of completely positive perturbations of a no-event semigroup. By construction these are either of Type I or Type II.

description: This article presents a dynamic bioeconomic model of livestock disease control that is unique in its integration of disease dynamics, inter‐species interaction, control‐induced migration, and individual optimising behaviour. Examination of the first‐order conditions highlights why profit‐maximising producers cannot be expected to eradicate disease. Results from an empirical application of the model confirm that the current mix of policies to control bovine tuberculosis in New Zealand is achieving lower levels of prevalence than would prevail in the absence of a national strategy. These policies do, however, appear to remove some of the individual incentive to control disease.
