3-D System in Package: How to Cope with Increasing Challenges
Authors: Mack Walter
Published: August 2022

It seems that scaling of chip technology according to Moore’s Law will continue for digital functionalities (logic and memory); however, increasing system integration on chip and package levels, called “More than Moore,” has been observed in the past several years. This strong trend in the worldwide semiconductor industry enables more functionality, diversification, and higher value by creating smart microsystems. This article discusses the many challenges faced in FA of 3-D chips, where well-staffed and equipped FA labs are essential. Furthermore, FA is becoming an important strategic enabling factor for new products, not just another “cost factor.”

Authors: Cobos Codina Sergi , Bernal García Luis Miguel , Rodríguez Sánchez José Antonio , Gavilán Iglesias Tania , de Alarcón Luis Fernández
Published: August 2022

BACKGROUND

Tentorial dural arteriovenous fistulas (DAVFs) with perimedullary venous drainage causing cervical myelopathy are very uncommon conditions with an extremely aggressive behavior. When the characteristic radiological clues are missing, the unspecific clinical picture may cause delay and make the diagnosis challenging.

OBSERVATIONS

Here the authors report a case of a 58-year-old man who developed progressive spastic tetraparesis and dyspnea with an extensive mild enhancing cervical cord lesion initially oriented as a neurosyphilis-associated transverse myelitis. Acute worsening after steroid administration redirected the diagnosis, and a tentorial Cognard type V DAVF was elicited. The microsurgical disconnection process is described, and previously documented cases in the literature are reviewed.

LESSONS

If a DAVF is highly suspected, it is important to consider the possibility of its intracranial origin, and spinal as well as cerebral arteriography must be performed.
Spinal cord stimulator for the treatment of central neuropathic pain secondary to cervical syringomyelia: illustrative case
Authors: Schatmeyer Bryan A. , Dodin Rakan , Kinsman Michael , Garcia David
Published: August 2022

BACKGROUND

Central neuropathic pain (CNP) of the cervical and/or thoracic spinal cord has many etiologies, both natural and iatrogenic. Frequently, CNP is medically refractory and requires surgical treatment to modulate the perception of pain. Spinal cord stimulation is a modality commonly used in adults to treat this type of refractory pain; however, it is rarely used in the pediatric population.

OBSERVATIONS

The authors reported a case involving a common pediatric condition, Chiari malformation type I with syrinx, that led to a debilitating complex regional pain syndrome. The associated life-altering pain was successfully alleviated following placement of a spinal cord stimulator.

LESSONS

CNP, or the syndromic manifestations of the pain (complex regional pain syndrome), can alter an individual’s life in dramatic ways. Spinal cord stimulator placement in carefully selected pediatric patients should be considered in these difficult pain treatment paradigms.

Authors: Ohno Masasuke , Kuramitsu Shunichiro , Iwakoshi Akari , Yamaguchi Junya , Ohka Fumiharu , Saito Ryuta
Published: August 2022

BACKGROUND

Although the risk of developing malignant lymphoma is higher in patients with rheumatoid arthritis (RA) than in the general population, primary central nervous system lymphoma (PCNSL) in patients with RA is extremely rare. In recent years, there has been concern that biological disease-modifying antirheumatic drugs (bDMARDs), widely administered to patients with RA, might increase the risk of cancer development. The authors report the first case of PCNSL in a patient with RA receiving the bDMARD tocilizumab.

OBSERVATIONS

A 70-year-old man who was diagnosed with RA in 2010 was treated with low-dose methotrexate (MTX) from 2010 to 2015. Tocilizumab was commenced in 2012. In 2018, he developed gait disturbances, and gadolinium-enhanced magnetic resonance imaging showed multiple contrast-enhanced lesions in the basal ganglia and brain stem. Stereotactic brain biopsy led to the diagnosis of diffuse large B-cell lymphoma, and finally PCNSL was diagnosed. He was treated with five courses of MTX 3.5 g/m2, and his disease has been in remission for 34 months.

LESSONS

Low-dose MTX and bDMARDs are associated with the concern of increased cancer risk in patients with RA. Because tocilizumab has been in use for a relatively short time, further accumulation of cases and careful follow-up are necessary.
Two-Chamber Unit for Detecting Parameters in the Neutron Flux
Authors:   Institute for Safety Problems of Nuclear Power Plants, NAS of Ukraine, Kuchmagra O. A. , Odynokin G. I.
Published: August 2022

The detection unit contains two neutron detectors — fission chambers KNT-31 or KNT 31–1, in which the radiator sensitive to neutron radiation is 235U (concentration of 235U in the radiator is more than 90%). The detection unit also includes two radiation- resistant preamplifiers (primary electronic equipment), which are connected to the cable transmission line to the secondary equipment, which captures the moment of pulses from the reaction of neutrons with the fission chamber radiator and save information about the time of these pulses. Further processing of the intervals between neutron events (intervals between pulses) can be done according to individual methods of the experimenter. The presence of a data processing unit type B-471 significantly expands the capabilities of the experimenter on the conclusions of statistical analysis of data and forecasting the development of emergencies in fuel-containing materials of the Shelter object. The presence of time intervals in the nanosecond range of values with sufficient probability can be classified as pulses of registration of instantaneous fission neutrons, and a change in their number may indicate a change in the effective multiplication factor of fuel containing materials. The analysis of the statistical properties of the flow of neutron event recording intervals by the electronic equipment makes it possible to predict the occurrence of a self-sustaining chain reaction. This is the main task of the Shelter object nuclear safety system. The proposed configuration of the CPI is promising and can be expanded by the number of fission chambers and electronic neutron detection units for more accurate diagnosis and prediction of the state of fissile nuclear materials.
Three-level model assessment of potential scenarios of the Shelter object transformation into an ecologically safe system based on global factor
Authors:   Institute for Safety Problems of Nuclear Power Plants, NAS of Ukraine, Derenhovskyi V. V. , Skiter I. S.
Published: August 2022

The paper presents research related to the analysis of scenarios for the transformation of the Shelter object into an ecologically safe system. Despite the long lifetime of the New Safe Confinement (NSC), which is 100 years, the presence of transuranic elements in fuel-containing materials (FCM) will pose a threat to the environment for many thousands of years. This indicates that the problem of choosing scenarios for further transformation of the Shelter object into an ecologically safe system remains relevant even after the commissioning of the NSC and requires special research. Among the tasks of analysis of potential scenarios for the transformation of the SO into an ecologically safe system after the commissioning of the NSC are: identification and analysis of factors influencing the choice of scenarios for the transformation of the SO; development of a methodology for comparative analysis of scenarios for the transformation of the SO into an ecologically safe system; comparative analysis of scenarios for the transformation of the SO into an ecologically safe system and the choice of the best one for implementation. The parameters of scenario evaluation and requirements for their submission are defined. An algorithm for building a model for estimating scenarios based on factorial- indicator sets has been developed. A model for increasing the level of consistency of pairwise comparisons of alternatives in determining the global criterion of the value of scenarios is proposed. A three- level scenario assessment model has been created. The correction of the method of analysis of hierarchies for the purpose of formation of the coordinated matrices of pairwise comparisons of indicators in separate factors and the general coordinated matrix of factors comparisons is proposed. The developed model makes it possible to determine the global values of scenarios on the basis of factor- indicator estimates. The use of the proposed methodology allows us to streamline, algorithmize and adjust the procedure of expert evaluation of qualitatively and quantitatively heterogeneous factors and improve the quality of the results to form a decision- making process to transform the SO into an ecologically safe system.
Comparative assessment of the dynamics of the average annual deposition velocity of 90Sr and 137Cs for a long term period after the Chornobyl accident for the cities of Ukraine, Kyiv and Chornobyl
Authors:   Institute for Safety Problems of Nuclear Power Plants, NAS of Ukraine, Novikov A. M.
Published: August 2022

A reliable assessment of the radioactive aerosol spread is an environmental safety task of current interest and high priority. An important parameter, used to calculate the transport of radioactive fallout, is the deposition velocity of radioactive aerosol. Fluctuations in the deposition velocity, which according to experimental data are within several orders of magnitude, depend on a number of factors (including time), which requires a detailed analysis of the patterns of radioactive pollution fields formation of air and the underlying surface. In this radio- ecological study, the dynamics of the average annual values of the deposition velocity of 90Sr and 137Cs were evaluated and analyzed, based on the experimental data of the measurements of the volume activity and the depositional fluxes obtained in Ukraine for the cities of Kyiv and Chornobyl after the Chornobyl nuclear power plant accident, during 1987–2019. The deposition rates for 90Sr and 137Cs estimated over a long period of time (33 years) show different trends. The total deposition velocity of 90Sr tends to increase, while for 137Cs the deposition velocity decreases over time. This pattern is characteristic of the two studied sites (Kyiv and Chornobyl). Relevant trends in the dynamics of deposition velocity may indicate the transformation of aerosol carriers of these radionuclides, their aerodynamic and migratory capabilities. This study could be of use for an empirical parameterization of deposition velocities in air quality models.

Authors: Murzea Cristinel Ioan
Published: August 2022

The year 1866 would represent a challenge for Romanian diplomacy, as the dethronement of Al. I. Cuza, the great powers would be led to discuss the rescinding of the 1859 act and, implicitly, the return to the political regime which would have caused the two principalities serious damage to their autonomy, both on an internal level, as well as external and it would be met with opposition from the great powers, as the young Romanian national state would meet its major objectives, thus creating a favorable international context in order to acquire state independence.
Western flanks of the Central Asian late paleozoic continental rift system and uranium mineralization
Authors: Malyutin S. A.
Published: August 2022

Introduction. Available information on the occurrences of high alkaline magmatic rocks fixing the position of the western flanks of the southern branches (Gobi Altai and Gobi Tien-Shan) of the Central Asian Late Paleozoic continental rift system in the territory of the North-West of Chingiz (the eastern part of Central Kazakhstan), the Kendyktas-Chu-Ili-Bet-Pak-Dal uranium-bearing province of the Southern Kazakhstan and the Chatkal-Naryn zone of Tien-Shan (Uzbekistan) is reviewed. Data on the confinement of uranium mineralization to these occurrences and its paragenetic relationship with the Late Paleozoic alkaline volcanic-plutonic association is provided.Aim. To study the uranium mineralization of Late Paleozoic alkaline magmatism to clarify metallogenic representations and justify prospects for the ore-bearingness of the western flanks of the southern branches of the Central Asian continental rift system.Materials and methods. The largest part of materials was obtained in the process of geological surveys and prospecting works of various scales in the regions of Central Kazakhstan in the period 1965–1985 with the participation of the author. Published materials concerning the subdivision of magmatic formations in the uranium ore fields of Southern Kazakhstan and the Chatkal-Naryn zone were also used.Results. Subvolcanic bodies of comendites and small masses of alkaline granites of the Late Paleozoic were identified across the area of uranium ore occurrences in the South-Western Chingiz and some deposits of South Kazakhstan confined to Devonian volcanic structures, which indicates their relationship with the southern branches of the Central Asian continental rift system. Rare-metalalbite, uranium-phosphorus and uranium-molybdenum formations are confined to alkaline rocks. Rare-metal mineralization is closely associated with alkaline rocks, while uranium mineralization occurred after the introduction of the most recent microgabbrodiorite and lamprophyre dikes. Similar correlations of rare-metal and uranium mineralization with alkaline granites and of microgabbrodiorite and lamprophyre dikes are observed in the uranium deposits of the Chatkal-Naryn zone located among the early Permian bimodal trachybasalt-trachyolite formation.Conclusion. The establishment of ore mineralization on the western flanks of the Gobi Altai and Gobi Tien-Shan branches in the territory of Southern and Central Kazakhstan allows these areas to be distinguished as metallogenic zones, promising in terms of rare-metal and uranium mineralization.

Authors: Mamedov R. A. , Allanazarova M. A. , Sagdeev R. R. , Suyunbaev T. N.
Published: August 2022

Introduction. East Siberian Sea shelf refers to the Novosibirsk-Chukotka prospective oil and gas province. The definition of the East Siberian shelf as a prospective oil and gas province and its division into areas is based, along with the structural and geological prerequisites, on the identification of numerous bitumen occurrences in the Paleozoic, Triassic and Jurassic sediments of the Novosibirsk Islands.Aim. To construct spatio-temporal digital models of sedimentary basins and hydrocarbon systems for the main horizons of source rocks, as well as to carry out their detailed analysis based on the available information about the oil and gas content, the gas-chemical composition of sediments, the characteristics of the component composition and evolution of source rocks within the studied prospective oil and gas province. The conducted research made it possible to study regional trends in oil and gas content, features of the sedimentary cover formation and the development of hydrocarbon systems in the area under study.Materials and methods. The materials of production reports obtained for individual large objects in the water area were the source of information. A basin analysis was based on a model developed by the Equinor specialists (Somme et al., 2018) [8, 9], which covered the time period from the Triassic to Paleogene inclusive and took into account the plate-tectonic reconstructions performed by Dor’e et al. in 2015. The resulting model included four main sedimentary complexes: pre-Aptian, Apt-Upper Cretaceous, Paleogene, and Neogene-Quaternary.Results. The calculation of numerical models was carried out in two versions with different types of kerogen of oil and gas source strata corresponding to humic and sapropel organic matter. The key factor in controlling the development of hydrocarbon systems was found to be the sinking rate of the basins and the thickness of the formed overburden complexes.Conclusion. The conducted analysis allowed the most promising research objects to be identified. The main foci of hydrocarbon generation in the Aptian-Late Cretaceous and Paleogene complexes were identified, along with the area of their most probable accumulation. Significant hydrocarbon potential is expected in the Paleogene clinoforms of the Eastern Arctic. This complex is currently underestimated, thus requiring further resource assessment study. A detailed mapping of its interior structure should be carried out.

Authors: Romanov V. V.
Published: August 2022

Introduction. The state of the terminological base used in the field of two-dimensional seismic surveying in the period 1933–2015 is analyzed and proposals to revise some key concepts are made.Aim. An analysis of the existing terminological base of the procedure of two-dimensional seismic surveying and the formation of a new base on the basis of a system approach.Materials and methods. An analysis of the terms used in educational, reference and normative literature on seismic surveying published in 1933–2015, followed by a critical analysis of the revealed terminological bases.Results. The investigated interval was divided into three stages on the basis of the state of terminology applied in seismic surveying. The first stage covered the period from 1933 to 1959, when the fundamental concepts of seismic surveying technology were passing the stage of formation. The quantity of terms at that time was small, many of them were characterised by unwieldiness or uncertainty of the described concept. In the period 1960–1992, the forming terminological base was presented in a state standard. The third stage was characterized by a slow pace of terminology development, when a number of publications showed a return to outdated or unsuccessful terms. The author identified the most stable terms, their unified names and definitions, and provided recommendations for their use. The following definitions of key concepts were proposed for revision: placement removal (distance), taking into account the variety of observation systems used in 2D seismic surveying; new terms inherited from the practice of 3D seismic surveying and group theory, including receiving line, placement removal, template, template step, order. A classification of templates was considered.Conclusion. The state of the terminological base in the field of two-dimensional seismic surveying, including its shortcomings and problems, was analyzed. It is proposed to improve the current terminological base by adding new terms and revising the existing definitions.
Neotectonic structures and modern geodynamics of the middle flow region of the Don river (the territory of the Novovoronezh nuclear power plant)
Authors: Makeev V. M. , Pikulik E. A. , Guseltsev A. S.
Published: August 2022

Background. Structural and geodynamic studies are conducted in the region of the middle flow of the Don river.Aim. An identification and evaluation of neotectonic structures, determination of geodynamic conditions for their formation and an analysis of intensive exogenous geological processes in connection with the need to ensure the safety of the Novovoronezh nuclear power plant (NPP) located in this area, the largest in the central part of the Eastern European platform.Materials and methods. According to the concept of deep geodynamic systems, the lithological, structural-geomorphological and neotectonic conditions of the territory were studied. Field observations and publications based on geological survey data were the factual material for the studies.Results. Various types of uplifts and troughs, geodynamically active zones and lineaments were identified. The formation of structures is associated with deep (intracortical) stresses of compression and tension, under the influence of which the tectonic-gravity and suffosion-karst processes negative for the territory of the nuclear power plant are activated. Among the ancient Precambrian faults of the crystalline basement, the latitudinal Sudzhen-Ikorets and submeridional Semiluki-Lipetsky faults are active. The latter is considered as a geodynamically active zone. At the NPP site and in its vicinity, the zones of increased fracturing and permeability were identified, which is consistent with the buried forms of the relief — paleo-reliefs of the Don river and its tributaries. These zones are found to be deeply embedded in the Cretaceous and Devonian carbonate rocks, which is the reason for the increased leaching of these rocks and the removal of fine particles from the fluvioglacial strata. A quantitative assessment of summary and step-by-step amplitudes and speeds of neotectonic movements was carried out.Conclusion. The territory of the Novovoronezh NPP is geodynamically calm, the movement speeds (both calculated and according to instrumental measurements) are relatively low; however, these movements activate exogenous processes, which in turn negatively affect the stability of the Novovoronezh NPP site.
