Some Fixed Point Results on Relational Quasi Partial Metric Spaces and Application to Non-Linear Matrix Equations
Authors: Jain Reena , Nashine Hemant Kumar , Kadelburg Zoran
Published: June 2021

We introduce a qϱ-implicit contractive condition by an implicit relation on relational quasi partial metric spaces and establish new (unique) fixed point results and periodic point results based on it. We justify the results by two suitable examples and compare with them related work. We discuss sufficient conditions ensuring the existence of a unique positive definite solution of the non-linear matrix equation U=B+∑i=1mAi*G(U)Ai, where B is an n×n Hermitian positive definite matrix, A1, A2, … Am are n×n matrices, and G is a non-linear self-mapping of the set of all Hermitian matrices which is continuous in the trace norm. Two examples (with randomly generated matrices and complex matrices, respectively) are given, together with convergence and error analysis, as well as average CPU time analysis and visualization of solution in surface plot.
Exploring QED Effects to Diphoton Production at Hadron Colliders
Authors: Cieri Leandro , Sborlini German
Published: June 2021

In this article, we report phenomenological studies about the impact of O(α) corrections to diphoton production at hadron colliders. We explore the application of the Abelianized version of the qT-subtraction method to efficiently compute NLO QED contributions, taking advantage of the symmetries relating QCD and QED corrections. We analyze the experimental consequences due to the selection criteria and we find percent-level deviations for Mγγ>1TeV. An accurate description of the tail of the invariant mass distribution is very important for new physics searches which have the diphoton process as one of their main backgrounds. Moreover, we emphasize the importance of properly dealing with the observable photons by reproducing the experimental conditions applied to the event reconstruction.

The carry-over of zearalenone (ZEN) to the myocardium and its effects on coronary vascular reactivity in vivo have not been addressed in the literature to date. Therefore, the objective of this study was to verify the hypothesis that low ZEN doses (MABEL, NOAEL and LOAEL) administered per os to prepubertal gilts for 21 days affect the accumulation of ZEN, α-ZEL and β-ZEL in the myocardium and the reactivity of the porcine coronary arteries to vasoconstrictors: acetylcholine, potassium chloride and vasodilator sodium nitroprusside. The contractile response to acetylcholine in the presence of a cyclooxygenase (COX) inhibitor, indomethacin and / or an endothelial nitric oxide synthase (e-NOS) inhibitor, L-NAME was also studied. The results of this study indicate that the carry-over of ZEN and its metabolites to the myocardium is a highly individualized process that occurs even at very low mycotoxin concentrations. The concentrations of the accumulated ZEN metabolites are inversely proportional to each other due to biotransformation processes. The levels of vasoconstrictors, acetylcholine and potassium chloride, were examined in the left anterior descending branch of the porcine coronary artery after oral administration of ZEN. The LOAEL dose clearly decreased vasoconstriction in response to both potassium chloride and acetylcholine (P < 0.05 for all values) and increased vasodilation in the presence of sodium nitroprusside (P = 0.021). The NOAEL dose significantly increased vasoconstriction caused by acetylcholine (P < 0.04), whereas the MABEL dose did not cause significant changes in the vascular response. Unlike higher doses of ZEN, 5 μg/kg had no negative influence on the vascular system.
New Developments in PCR-Based Diagnostics for Bacterial Pathogens Causing Gastrointestinal Infections—A Narrative Mini-Review on Challenges in the Tropics
Authors: Loderstädt Ulrike , Hagen Ralf Matthias , Hahn Andreas , Frickmann Hagen
Published: June 2021

The application of modern PCR approaches for the diagnosis of bacterial gastrointestinal pathogens is on the rise due to their rapidly available results combined with high sensitivity. While multiple studies describe the ongoing implementation of this technique for routine diagnostic purposes in laboratories in Western industrialized countries, reports on successful and also sustainable respective approaches in resource-poor tropical settings are still scarce. In order to shed light on potential reasons for this marked discrepancy, this narrative review summarizes identified challenges for the application of diagnostic PCR targeting bacterial gastrointestinal pathogens from stool samples in the tropics. The identified and discussed issues comprise the lack of generally accepted definitions for (1) minimum standards regarding sample acquisition, storage and transport time for diagnostic PCR analyses in the tropics, (2) nucleic acid extraction standards allowing an optimum detection of all types of pathogens which may be responsible for gastroenteritis in the tropics, (3) validation standards to ensure comparable quality of applied diagnostic assays, and (4) cut-offs for a reliable discrimination of infection and mere colonization in areas where semi-immunity due to repeated exposition associated with poor hygiene conditions has to be expected. Further implementation research is needed to solve those issues.

In 2012, Tigray orthohantavirus was discovered in Ethiopia, but its seasonal infection in small mammals, and whether it poses a risk to humans was unknown. The occurrence of small mammals, rodents and shrews, in human inhabitations in northern Ethiopia is affected by season and presence of stone bunds. We sampled small mammals in two seasons from low- and high-density stone bund fields adjacent to houses and community-protected semi-natural habitats in Atsbi and Hagere Selam, where Tigray orthohantavirus was first discovered. We collected blood samples from both small mammals and residents using filter paper. The presence of orthohantavirus-reactive antibodies in blood was then analyzed using immunofluorescence assay (human samples) and enzyme linked immunosorbent assays (small mammal samples) with Puumala orthohantavirus as antigen. Viral RNA was detected by RT-PCR using small mammal blood samples. Total orthohantavirus prevalence (antibodies or virus RNA) in the small mammals was 3.37%. The positive animals were three Stenocephalemys albipes rats (prevalence in this species = 13.04%). The low prevalence made it impossible to determine whether season and stone bunds were associated with orthohantavirus prevalence in the small mammals. In humans, we report the first detection of orthohantavirus-reactive IgG antibodies in Ethiopia (seroprevalence = 5.26%). S. albipes lives in close proximity to humans, likely increasing the risk of zoonotic transmission.

Published: June 2021

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is currently spreading and mutating with increasing speed worldwide. Therefore, there is an urgent need for a simple, sensitive, and high-throughput (HTP) assay to quantify virus–host interactions in order to quickly evaluate the infectious ability of mutant viruses and to develop or validate virus-inhibiting drugs. Here, we developed an ultrasensitive bioluminescent biosensor to evaluate virus–cell interactions by quantifying the interaction between the SARS-CoV-2 receptor binding domain (RBD) and its cellular receptor angiotensin-converting enzyme 2 (ACE2) both in living cells and in vitro. We have successfully used this novel biosensor to analyze SARS-CoV-2 RBD mutants and evaluated candidate small molecules (SMs), antibodies, and peptides that may block RBD:ACE2 interaction. This simple, rapid, and HTP biosensor tool will significantly expedite the detection of viral mutants and the anti-COVID-19 drug discovery process.

Published: June 2021

Physical-chemical and biologicaldiversity of streams are influenced by the land use in their watersheds. Plastics currently make up the most important waste asset, representing an important part of the transported and accumulated material in water courses. This work analyzes the consumption of plastics debris by the fish communities in streams with two contrasting types of land use. We worked with threestreams impacted by urbanization and threeby extensive ranching. The stomach and intestinal contents of 309 individuals of 29 species were analyzed, by a modified alkaline digestion, and observed under a stereo microscope with polarized light. A total of 373 plastic itemswere found, of which the majority corresponded to fibers (318). A significant difference was found between the percentage of individuals that consumed plastic debrisbetween both systems (51.6% in ranchers and 76.6% in urban, p = 0.014 Mood’s Median), but no difference was found in the average ingested per individual. This study establishes the first baseline on plastic debris consumption by fish in Uruguayan streams, showing the extent of the plastic and microplastic pollution problem. Although there are differences between the analyzed sites, we also observed significant contamination in streams far from urbanization.

Published: June 2021

As a result of the COVID-19 pandemic, the world economy has faced not only the problem of maintaining sustainable development and ensuring the well-being of citizens at the same level, but also with a number of problems caused by urgent challenges related to the need to organize remote education and work. As a result, many of the goals that are and were on the agenda of many government associations, organizations and institutions, such as food security, reducing poverty in developing countries, social and gender inequality, have been ‘postponed’ for an indefinite term. Accelerated digitalization has led not only to a change in the mode of operation of many enterprises, but also has had a significant effect on the consumer preferences of consumers of products produced in different industrial sectors. Although in many countries the restrictions (lockdown) caused by a new coronavirus infection are gradually decreasing, not all citizens are ready to return to their previous activities. It is important to understand that as the economy recedes, demand recovery will be unpredictable, uneven across geographical regions, sectors, product categories and consumer segments, and often slow. And if earlier methods of forecasting statistical indicators were actively used, which were based on values for previous periods, now they are simply unrepresentative. Drones that help deliver essential goods and conduct extensive analysis of highly populated areas, robots that allow remote commissioning and repair of devices and equipment, 3-D printing, which is actively used to develop product prototypes and create new images, blockchain technology to ensure the continuity and rhythm of goods deliveries in international logistics — all these methods, previously only rarely used in everyday life are becoming more necessary day by day. Special attention should be paid to educational technologies in the era of accelerated digitalization, in many ways, because in 10–15 years employees will have professions that simply do not exist now. That is why in the educational process it is necessary to create an environment where students will not just be recipients of information, but its generators, which will allow them to better navigate the new digital reality in the future.

Authors: Mashin Dmitrii Vasilyevich
Published: June 2021

All over the world, non-essential businesses were closed during the pandemic, which subsequently led to a deterioration in the economic condition of the whole world, the main negative factor was the surprise. The world economy was not prepared for such events. The service industry was completely destroyed along with the tourism and hotel industry. Companies that are able to work remotely were able to continue to work and survive the crisis. But industries that require personal interaction have been almost completely destroyed. This study aims to examine the impact of the COVID-19 pandemic on stock markets, as the stock market provides an updated summary of views on the ultimate impact of the COVID-19 pandemic. Based on the theoretical structure, the prices of securities always fully refl ect all available information. As a result, it can be expected that there should be a strong link between the COVID-19 pandemic and stock index returns. The aim of the work is to study the impact of the pandemic on the quotes of the leading players in the QSR market. To achieve this goal, the author analyzed the dynamics of stock indices that were aff ected by the pandemic, studied the prices per troy ounce of gold on MOEX, the US unemployment rate, the position of the stock indices of the US, Russia, Germany, Great Britain and France relative to 01.01.2020, the index of bond yields of companies with a Ba/BB rating.
Growth in the debt burden of the global economy: the scale and directions of counteraction in the context of the crisis
Authors: Smirnov Evgenii Nikolayevich
Published: June 2021

The article analyzes the key aspects of the debt burden, which has taken on an unprecedented scale in the economies of developed and developing countries. The coronavirus pandemic has led to a significant increase in government support for households and companies, while the volatility of global financial markets has increased. Given the continuing uncertainty about the further recovery of the global economy, the timing of countries’ return to pre-crisis levels of borrowing remains unclear. At the same time, we note a growing mismatch between risk assessments in financial markets and the expected outlook for economic recovery. Central banks of countries have taken unprecedented measures to counter the growth of debt burden, but in developing countries, the limited fiscal space does not allow effective measures to prevent the continued growth of debt. The article also notes that the cheapness of new loans is an aggravating factor in the growth of borrowings and the deterioration of the balance of payments. The author came to the conclusion that a sharp increase in public debt in many countries will preserve the vulnerability of the world economy, therefore, it is necessary to carefully adjust the fiscal policies of the countries of the world, modernize fiscal risk management strategies and modernize tax reforms. In addition, in conditions of high debt, approaches to assessing the risks of attracting foreign direct investment are changing, which in the future will have a significant impact on the redistribution of international capital flows. However, even in the face of excessive debt burden, governments need to continue lending support to households and companies in shortterm policies, in parallel with measures to manage capital outflows and achieve exchange rate flexibility.
Features of modeling of management consulting in modern conditions
Authors:   Vinnytsia Trade and Economy Institute of Kyiv National Trade and Economy University, Bondarchuk Liudmyla
Published: June 2021

In today's conditions, a major number of business structures in Ukraine use services of consulting companies, the main reasons are the ability to form a sequence of elements of the system of consulting model, necessity to provide confidential information to third party company, and also absence of previous experience of cooperation with consulting companies and low level of information about their activities in the media. That is why the spread of practice of using services of consulting companies in general and on issues of the organization of accounting work among national enterprises becomes especially relevant and important. In today's conditions there is an urgent need in the rational use of funds, means of labor and various resources by defining and implementing effective mechanisms of the management system at the level of the enterprise, which relevant form the list and the system of management consulting and consulting services. Features of modernity create important tools and means of interaction at the level of consulting services, and in particular the preparation of a consulting model and modeling elements of the mechanism of using management consulting, to which the relevant research is devoted. The demand of management consultants as experts of innovative development of organizations, and the creation of special components of the model of management services arethe important features of this area of activity at the state level. Thus, the ultimate goal of consultancy and as a result of creating a model of consulting services is the help the client to make progressive changes in his organization. In Ukraine, where political, economic, social, technological changes occur quite chaotic, it is necessary to take into account that fact that people and organizations need not only changes but also stability and continuity. Finding a balance between changes and stability is one of the main tasks of a consultant. Thus, consulting modeling is a professional activity which consists in providing independent and objective advice and technical assistance by qualified specialists, enterprises, and organizations to individual entrepreneurs in order to assist them in identifying and researching management problems, finding their optimal solutions, methodology of implementing recommendations.

Published: June 2021

The therapeutic outcomes of noninvasive sonodynamic therapy (SDT) are always compromised by tumor hypoxia, as well as inherent protective mechanisms of tumor. Herein, we report a simple cascade enzymatic approach of the concurrent glucose depletion and intratumoral oxygenation for starvation-sensitized and oxygenation-amplified sonodynamic therapy using a dual enzyme and sonosensitizer-loaded nanomedicine designated as GOD/CAT@ZPF-Lips. In particular, glucose oxidase- (GOD-) catalyzed glycolysis would cut off glucose supply within the tumor, resulting in the production of tumor hydrogen peroxide (H

In the meantime, the severe energy deprivation enabled by GOD-catalyzed glucose depletion would prevent tumor cells from executing protective mechanisms to defend themselves and make the tumor cells sensitized and succumbed to the cytotoxicity of

Eventually, GOD/CAT@ZPF-Lips demonstrate the excellent tumoral therapeutic effect of SDT in vivo without significant side effect through the cascade enzymatic starvation and oxygenation, and encouragingly, the tumor xenografts have been found completely eradicated in around 4 days by the intravenous injection of the nanomedicine without reoccurrence for as long as 20 days.

The chromite deposits of the Fiskenæsset region, West Greenland
Authors: Ghisler M , Windley B.F
Published: June 2021

The chromite deposits of the Fiskenæsset region occur in anorthosites, which together with intercalated pyribolites (hypersthene amphibolites) and subsidiary pyroxenites and peridotites occur in the gneisses as horizons belonging to a folded and metamorphosed stratiform complex which has a maximum thickness of 2 km. The chromite occurs in horizons which average 0.5 - 3 m in width, reaching a maximum of 20 m, and consist of alternating anorthosite and chromitite layers, usually between 0.5 and 10 cm wide. Chromite horizons occur in almost all of the anorthosite horizons in the region which have a minimum exposed length of 125 km. 175 X-ray fluorescence analyses show that the Cr2O3 content of the chromite varies between 26% and 36%, averaging 32.7%. The total iron oxide content varies between 28% and 42%, averaging 31. 8% (as FeO), with the result that the Cr:Fe ratio varies between 0.66 and 1.05, averaging 0.93. The chromite has a high V2O5 content varying from 0.2% to 0.5% with an average value of 0.3%. The chromite horizons occur along the shores of the fjords or only a few kilometres from the coast in easily accessible terrain that rarely exceeds 500 m in altitude. Fiskenæsset harbour is ice-free for the whole year.
Petrology and geology of the Precambrian Gardar Dykes on Qaersuarssuk, South Greenland
Authors: Watt W.S
Published: June 2021

The Precambrian Gardar dykes on Qaersuarssuk consist of olivine dolerites, a group of undersaturated to saturated microsyenites including one nepheline-bearing dyke, trachydolerites and lamprophyres. The dykes are the fringe to the dense swarm of alkaline dykes on Tugtutôq to the east. As most of the dykes are sub-parallel, division is made based on their relations to movements along wrench faults. Composite dykes, with microsyenitic marginal components, and trachydoleritic centres often containing large aggregates of feldspar crystals and giant single crystals of feldspar, are comparatively common.
Pseudotachylite in the Agto area
Authors: Jensen V
Published: June 2021

During field work in high-metamorphic complexes of the Agto area glassy pseudotachylite (in the sense of Philpotts, 1964) was found in several localities. The pseudotachylite is restricted to a few of the major movement-zones. These zones form rectilinear depressions which are very distinct on areal photographs and some are inferred to be of regional importance.
New field relations from the early Precambrian of West Greenland
Authors: Windley B.F
Published: June 2021

The following new field relations were found this summer in the region between Ravns Storø and Sukkertoppen. On western Nordland there is an anorthosite horizon with a maximum width of 6 km and a minimum length of 25 km which is the widest anorthosite so far known in West Greenland. This is a layered anorthosite grading into anorthositic norite which has been migmatised marginally by the surrounding hypersthene gneisses, but which is well preserved in its centre.
The geological setting and mineralizations west of Lilianmine, South Greenland
Authors: Ghisler M
Published: June 2021

The coastal strip of green schists at the south side of Kobberminebugt consists of a sequence of alternating meta-volcanic rocks and meta-sediments. Uralite porphyrite and subordinate plagioclase porphyrite represent the volcanic component of the geosynclinal deposits, whereas no meta-sediments have been recognized with certainty in the area under consideration. Pillow structures indicate the extrusive origin of the basic lavaflows and its original porphyritic texture is well-preserved at one locality. Different grades of pressure and metamorphism during the Ketilidian orogeny have elsewhere given rise to a transitional series from uralite porphyrite to schistose greenstone. A small composite intrusion with sharp contacts and a characteristic joint system is regarded to be an appinitic suite of Sanerutian age. A monzonitic magma was intruded into the centre of a gabbro body, a probable early derivative of which is represented by a hornblendite. A ringdyke of quartz dioritic composition intruded the basic rocks, the age relation to the monzonite remaining uncertain. Some irregular intrusive bodies of pink felsite, which in some places have the character of quartz porphyries, are based on the dolerite chronology, shown to be of Gardar age. A swarm of pegmatite dykes extends from the biotite granite of the Nunarssuit intrusive complex into the green schists. The subhorizontal pegmatites are interesting because of their rare minerals such as beryl, amazonestone, molybdenite, and aegirine with pseudomorphs of hematite in large crystals. Copper sulphides occur in the pegmatites, but are most important in the hydrothermal mineralizations along faults and shear zones, joints and fracture fillings. Bigger concentrations of ore have only been found in two places, but they are not of economic importance. Geophysical measurements with a magnetometer have shown anomalies in the green schists, which mainly are regarded to be due to different grades of compaction of the metamorphosed magnetite-bearing volcanic rocks. Geochemical analyses have been made on 4 rock samples, the results of which in relation with the distribution pattern of the mineralizations in the field suggest, that the copper necessary for the formation of the ores has been extracted from the green schists by hydrothermal activity, in this area related with the intrusion of the biotite granite. Trace element determinations on 2 botanical samples were made to test the possibilities for applicating two common plants in the region in geo-botanical prospecting.
Preliminary account of the geology of the Kvanefjeld Area of the Ilímaussaq Intrusion, South Greenland
Authors: Sørensen H , Hansen J , Bondesen E
Published: June 2021

The Kvanefjeld area is situated in the northernmost part of the nimaussaq intrusion. The area represents a section through the roof zone of this intrusion. The roof is composed of sandstone, basaltic lavas, sheets of gabbro and dykes of dolerite and trachyte. Large masses of anorthosite are also found in the roof zone, The oldest members of the intrusion are augite syenite and alkali syenite which together with large masses of naujaite (poikilitic sodalite syenite) are enclosed in various types of fine-grained lujavrite. The lujavrite also intrudes the lavas of the roof. The bodies and veins of lujavrite are mainly located in zones of deformation in the rocks of the roof zone. The lavas of the roof are strongly altered in contact with the lujavrite and are locally enriched in epistolite-murmanite minerals. The latest member of the intrusion is a medium- to coarsegrained lujavrite which forms sheets and veins in most of the abovementioned rocks. The earlier fine-grained lujavrites and the contactmetasomatized lavas have concentrations of steenstrupine, monazite and thorite (?) in contact with the medium- to coarse-grained lujavrite and may contain up to 0.3 % U and three to four times this amount of thorium. This mineralization has been studied by mineralogical, geochemical and radiometric methods and in a number of drill holes. Analcime-rich veins rich in niobium and beryllium minerals are of widespread occurrence. The present paper gives a preliminary account of the geology of this region with special reference to the structural geology. A detailed examination of the economic geology of the Kvanefjeld area is currently being undertaken.

Tertiary fluvial deposits of Jylland, Addit area
Authors: Hansen H.C.S
Published: June 2021

Sandy fluvial deposits of Tertiary age are described from three sand pits in the Addit area with up to 28 metres high outcrops. The deposits form up to 20 metres thick fining-upwards successions of mainly large-scale tabular cross-sets of medium and coarse sand interpreted as fluvial bars. Individual successions are capped by thinly interbedded sands and silts and occasionally completed with a coal bed. Concave-up bounding surfaces separate the fining-upwards successions. Channel switching, breaks in active channel aggradation, rapid scour- and filling events and chute activity created bounding surfaces described as a 4-tier hierarchy. The palaeocurrents derived from trough foresets suggest that the channel course was straight rather than sinuous. The current directions were generally to the south and southwest.
Regional Cenozoic uplift and subsidence events in the southeastern North Sea
Authors: Jordt Henrik
Published: June 2021

The Paleocene topography of the Fennoscandian Shield is indicated by outbuilding towards the Central Trough and the Ringkøbing-Fyn High. From Eocene until Pliocene time three events of relative vertical movements are indicated by changes in outbuilding directions and reflection termination patterns in the central North Sea. The first event of uplift was in the Eocene and resulted in relative uplift of the Mid North Sea High and contemporary subsidence east of it, indicated by a change in outbuilding from north to west. A second event of uplift is indicated to the north of the study area at the Eocene-Oligocene boundary by renewed southward outbuilding in the Norwegian-Danish Basin. In Miocene until Early Pliocene time a relatively stationary, almost east-west striking, basin margin was probably located to the north along the Tornquist Zone as indicated by the continued outbuilding towards the Ringk0bing Fyn High. A third event of relative uplift is indicated east of the study area by changes in the Pliocene outbuilding pattern. After the first event of uplift it appears that the deepest parts of the Eocene North Sea Basin were located more easterly than the deepest parts are today. Apparently the two latest uplift events north and east of the study area were related to movements of, or along the Tornquist Zone or to regional uplift of the Fennoscandian Shield finally resulting in the presentday configuration of the North Sea.
Pliocene - Middle Pleistocene biostratigraphy in the Central Danish North Sea wells E-1, P-1 and TWB-12
Authors: Pedersen Anette Mønsted
Published: June 2021

Six foraminiferal assemblage zones and 6 subzones have been identified in the boreholes TWB-12, P-1 and E-1. The zones cover the interval from the Pliocene to the Middle Pleistocene. In TWB-12 and E-1 the Pliocene /Pleistocene boundary is placed at the first common occurrence of the species Elphidium oregonense. This species was not found in P-1, and the boundary is here, tentatively, placed above the last local occurrence of Cibicides grossus. The palaeoecological variations indicated by the Pleistocene assemblages, suggest several oscillations both in water depth and in palaeotemperature. A cold, shallow water interval with Elphidium oregonense at the Pliocene/Pleistocene boundary is followed by a Early Pleistocene warm, deep water interval with a high content of the genera Stainforthia and Bulimina. These deposits are probably from the warm Tiglian stage. The succeeding Early Pleistocene fauna! assemblages indicate a cold, upwards shallowing environment, and in this interval the arctic species Elphidiella gorbunovi often has a short ranged occurrence. The fauna! assemblages of the overlying deposits are characterized by the species Elphidium ustulatum and Elphidium albiumbilicatum, and indicates nearshore/ deltaic conditions. This part of the sequence probably includes the Early /Middle Pleistocene boundary. The uppermost assemblages in the examined sequence indicate arctic, shallow water conditions. They are, probably, of Saalian age, and are referred to Middle Pleistocene.

Published: June 2021

The present study considers some trinitroazetidine isomers within the realm of density functional theory (B3LYP/6-311++G(d,p)). One of the isomers considered is 1,3,3-trinitroazetidine (TNAZ) which is the well known insensitive high energy explosive material. Various structural, energetic, quantum chemical and spectral properties of the isomers have been harvested and discussed. Some of the isomers have nitramine bonds and some possess only C-NO2 bonds. The results indicate that the nitramine moiety somewhat destabilizes the structure electronically but increases the impact insensitivity.
