In support of future radiation-effects testing, a combined environment source has been developed for the National Ignition Facility (NIF), utilizing both NIF’s long-pulse beams, and the Advanced Radiographic Capability (ARC) short pulse lasers. First, ARC was used to illuminate a gold foil at high-intensity, generating a significant x-ray signal &gt;1 MeV. This was followed by NIF 10 ns later to implode an exploding pusher target filled with fusionable gas for neutron generation. The neutron and x-ray bursts were incident onto a retrievable, close-standoff diagnostic snout. With separate control over both neutron and x-ray emission, the platform allows for tailored photon and neutron fluences and timing on a recoverable test sample. The platform exceeded its initial fluence goals, demonstrating a neutron fluence of 2.3 ×1013 n/cm2 and an x-ray dose of 7 krad.
Argument Continuities in theory and practice
Authors: Pimenova Oxana 
Published: October 2022

Abstract
Argumentation on some public policy issues is conjugated with disagreement and power differentials.
Institutionally dominant arguers control the argumentation context through imposing authority rules which sometimes incentivize
them to respond to opposing arguers in a fallacious way1 – with “the repeating tokens of the
same counterarguments” and without considering the merits of opposing arguments. As produced in accordance with authority rules,
such fallacies are embedded in the dominant argumentative discourse and easily pass unnoticed. To detect them, I introduce
Argument Continuity (AC) – a new category of argumentative discourse analysis. AC is a set of the same arguments and
counterarguments repeatedly produced/reproduced by the dominant arguer through an adversarial reasoning process to disconfirm
opposing arguments and dismiss them. ACs are distinguished from other fallacies by their continuous nature and recursive way of
production. ACs have their own life cycle – a chain of reasoning dynamics developing in a path-dependent fashion and increasing
the cost of adopting a certain argument over time. I test the life cycle of ACs in a single case study – in consultations held by
the Crown with Indigenous peoples of Canada over a controversial resource development project. Although ACs are not specific to
the Crown-Indigenous relationships, they reveal how dominant arguers treat disagreement from epistemically diverse arguers. Based
on observed evidence, I develop three theoretical propositions of ACs, which can serve as guidelines for researching the
disconfirming mode of reasoning in other contexts of communication permeated by beliefs clash and power asymmetries.

Two-dimensional localization in GeSn

Abstract
Localization behaviour is a characteristic feature of the p-type GeSn quantum well (QW) system in a metal–insulator–semiconductor device. The transition to strongly localized behaviour is abrupt with thermally activated conductivity and a high temperature intercept of 0.12 × e

The activation energy for the conductivity in the localized state is 0.40 ± 0.05 meV compared to an activation energy of ∼0.1 meV for conductivity activation to a mobility edge at carrier densities >1.55 × 1011 cm−2. Insulating behaviour can occur from a system that behaves as though it is in a minimum metallic state, albeit at high temperature, or from a conductivity greater than a minimum metallic state behaviour showing that local disorder conditions with local differences in the density of states are important for the onset of localization. In the presence of a high magnetic field, thermally activated conductivity is present down to Landau level filling factor <

In the localized transport regime in p-type doped Ge0.92Sn0.08 QWs the VRH mechanism is suppressed at temperatures >100 mK and this makes this two-dimensional system ideal for future many body localization studies in disordered hole gases that can be thermally isolated from a temperature reservoir.
Self-interacting freeze-in dark matter in a singlet doublet scenario
Authors: Ghosh Purusottam , Konar Partha , Saha Abhijit Kumar , Show Sudipta 
Published: October 2022

Abstract
We examine the non-thermal production of dark matter in a scalar extended singlet doublet
fermion model where the lightest admixture of the fermions constitutes a suitable dark matter
candidate. The dark sector is non-minimal with the MeV scale singlet scalar, which is stable in
the Universe lifetime and can mediate the self-interaction for the multi-GeV fermion dark matter
mitigating the small scale structure anomalies of the Universe. If the dark sector is strongly
coupled to yield a velocity dependent large self-interaction cross section, it undergoes internal
dark thermal equilibrium after freeze-in production. We essentially end up with suppressed relic
abundance for the fermion dark matter in a traditional radiation dominated Universe. In contrast,
the presence of a modified cosmological phase in the early era drives the fermion dark matter to
satisfy nearly the whole amount of observed relic. It also turns out that the assumption of an
unconventional cosmological history can allow the GeV scale dark matter to be probed at LHC from
displaced vertex signature with improved sensitivity.
The additional optical angular momentum flux in media with nonlocality of nonlinear optical response
Authors: Ryzhikov P S , Makarov V A 
Published: October 2022

Abstract
The additional terms caused by the nonlocality of the nonlinear optical response of the medium in the expressions for the optical angular momentum density, the optical angular momentum flux density and the torque density on light, which are related to each other by the angular momentum transformation law, are obtained as a consequence of peculiarities of the momentum conservation law in such media. It is shown that the manifestation of the nonlocality of the optical response only changes the form of polarization of medium included in the expression for the angular momentum density, whereas the definition of the angular momentum flux density contains additional term depending on the nonlocal nth order nonlinear optical susceptibility.
Bose–Einstein condensation of two-dimensional spin-1 Cooper pairs in a uniform magnetic field
Authors: Cheng Ze 
Published: October 2022

Abstract
Bose–Einstein condensation of two-dimensional spin-1 Cooper pairs in a uniform magnetic field is investigated within the framework of quantum statistical mechanics. We derive an exact analytical solution of two-dimensional spin-1 Cooper pairs in a uniform magnetic field, which involves a q-digamma function in mathematics. In two dimensions, it is found that the critical temperature and condensate fraction are monotonically increasing functions of magnetic field B, Landé factor g, and number density σ. Our investigation in two dimensions provides an example of the magnetic-field-tuned insulator-superconductor quantum phase transition.

Microwaves propagation through a small fire curtain at 3.55 GHz and 6.26 GHz and the impact on vital signs detection by using a four-element patch antenna array
Authors: Miclăuş S , Vatamanu D , Mitran R , Neghină C 
Published: October 2022

Abstract
The impact of the presence of a fire curtain not wider than 7 cm on an air path 150 cm long of two continuous waves at frequencies of 3.55 GHz and 6.26 GHz was quantified. Two identical patch array antennas with four linear elements were used at emission and reception and they were designed and characterized specifically for this purpose. The magnitude and phase of the transmission coefficient were measured by a vector network analyzer in all the experimental sessions. Comparing the air path and the air-plus-fire path of the waves, it resulted that fire induced shifts in magnitude and phase that depended on frequency and on the experimental setup. The heating of the antenna could have contributed to the overall observed effects. The detection of the human heartbeat by Doppler radar technique was not much influenced by the presence of fire, but the amplitude of the detected beats was increased. The array antennas produced noisy signals for the vital sign detection and the origin of this behaviour was hypothesized.

Pre-compliance testing of the shielding effectiveness of 3D printed multiwall carbon nanotube/ethylene-vinyl acetate copolymer composites in the 1 – 7 GHz range
Authors: Deaconescu D B , Vatamanu D , Miclăuş S , Stan F , Sandu I 
Published: October 2022

Abstract
Copolymer composites with 1-, 3- and 5 % weight concentration of carbon nanotubes (CNT) with average diameters of 9.5mm were fabricated using three different printing orientations: 0°, alternative ± 45°, and alternative +0°/- 90°. Shielding effectiveness (SE) of samples of 100x100x1 mm was measured with near-field probes connected to a vector network analyser based on a pre-compliance procedure. Both electric- and magnetic-shielding properties could be investigated. Using a reference material of a recognised producer, we emphasized comparative shielding properties in the (1-7) GHz range. Low SE values were generally observed for all samples, not exceeding 12.5 dB, but they were dependent on both the printing direction and CNT wt%. The measurements indicate that frequencies larger than 7 GHz may show better shielding properties. Also, indications of the best combination between CNT concentration and printing direction were deducted.
The Effect of 1.74 and 2.3 GHz Microwave Exposure of Ailanthus Altissima Leaf Extracts on their Antioxidant Content and Activity
Authors: Cocîrlea M D , Miclăuş S , Oancea S 
Published: October 2022

AbstractMicrowave (MW) irradiation in reactors with input power levels of 200-1000 W has been frequently applied for the extraction of natural compounds from vegetal material. The aim of the present research was to investigate the effect of much lower MW input powers (< 12 W) delivered through antennas into shielded enclosures on mixtures of ethanol solution-Ailanthus altissimaleaves (frozen and oven-dried), at different frequencies (1.74 and 2.3 GHz) and exposure times (0.5, 1 and 3 h). The phenolic content and antioxidant activity were quantified after the exposures. Significant differences between the antioxidant content/ activity and the type of raw material were found, in favour of frozen samples. After MW treatment, the bioactive content and activity increased in frozenAilanthusleaf extracts compared to control. No significant effect was observed in case of extracts prepared from oven-dried samples at 60°C. The ATR-FTIR analysis indicates no significant structural changes after the irradiation. These results revealed a better extractability of phenolic compounds following MW exposure in particular at 2.3 GHz.
Magnetic Hyperthermia with biocompatible coated nanoparticles: A temperature analysis
Authors: Aştefanoaei I , Stancu A 
Published: October 2022

Abstract
The magnetic nanoparticles (MNPs) having the special (magnetic and thermal) properties are promising for Magnetic Hyperthermia. To increase their biocompatibility, these MNPs are covered by different organic shells as: chitosan, oleic acid or silica. When an external time - dependent magnetic field is applied, the temperature developed within a malignant cell is strongly influenced by the type of the material which covers the magnetic nanoparticle. This paper studies the temperature field induced by the MNPs covered by an organic shell within a concentric tissues configuration (malignant and healthy tissues). The shell thickness influences significantly the temperature field developed within a malignant tissue. These important effects should be considered in the computation of the specific particle doses corresponding to the hyperthermia treatment.
On the adapting ability of living organisms to stationary and non-stationary electromagnetic fields
Authors: Roşu G , Spandole-Dinu S , Catrina A-M , Tuţă L , Baltag O , Fichte L O 
Published: October 2022

Abstract
The adapting ability of living organisms is the key to survival of the species, and its scope is defined by homeostasis, meaning the tendency of any living system to maintain its biologic parameters. Heat shock proteins are part of a homeostasis system in charge with the regulation of damaged proteins caused by the action of several types of stressors. Among all types of stressors, the electromagnetic radiation has not yet been investigated in terms of heat shock protein response. Recent investigations regarding in vivo experiments using electromagnetic exposure from laboratory sources and commercial mobile phones indicate that the biologic response is more intense when using real life sources. This paper proposes a model for heat shock proteins expression as response to electromagnetic radiation exposure, based on a Hill controller.

Published: October 2022

Abstract
Some of the most common chronic respiratory diseases, incapacitating the development and quality of life of patients and directly correlated with oro-dental cavity are represented by asthma and chronic obstructive pulmonary disease (CPOD), a chronic inflammatory disease affecting the airways, in which mast cells, eosinophils and T lymphocytes, play an important role [1]. A better understanding of the diagnosis and treatment of these pathology became possible by accepting that the existence of chronic inflammation, with its variations, is reflected in the clinical condition of the elderly patients, with implications on the dental status. Therefore, the present research, using respiratory biomedical explorations, wants to establish a clinical and functional correlation in the case of elderly patients with respiratory diseases and who associate oro-dental pathologies. In the current conditions, in which the predominant viral damage is SARS-COV 2 infection, it is necessary to develop a clinical-functional algorithm to quickly establish a subsequent evolution and prognosis of elderly patients, which involve an increased predisposition to morbidity and mortality.

Abstract
A new semiconductor material tetrakis-μ3-(methoxo)(methanol)-pentakis (acetylacetonate)(tricopper(II), samarium(III)) (I) with composition [Cu3Sm(AA)5(OCH3)4CH3OH], where HAA = H3C–C(O)–CH2–C(O)–CH3 has been synthesized. By the data of elemental analysis and physicochemical research methods, it was established that the obtained complex compound (I) contained atoms of copper (II) and samarium (III) in ratio Cu:Sm = 3:1, and its composition corresponded to the gross formula Cu3SmO15C30H51. Electrical conductivity of the obtained material in pressed form was measured. For the complex compound (I) such parameters were calculated: the number of valence electrons in one molecule − 272; mass of one molecule − 164.867∙10-20 kg; the total number of molecules in the cylindrical sample of a 0.131 g mass and a 18.24∙10-9 m3 volume − 7.946∙1013 moleculas; the total number of valence electrons − 272. In the 303~413 K temperature range, the resistivity of the pressed sample decreases from 4∙1011 to 7∙104Ohm∙cm, which confirms that the isolated compound is a semiconductor with a bandgap ΔE = 1.526 eV. Electrical conductivity properties of the complex compound as thermo- and magnetically sensitive element were studied, for this purpose a test sample of compressed material with 0.5×0.5×1.0 mm geometric dimensions was utilized.

Published: October 2022

Abstract
The primary goal of this work is to analyse the panoramic dental radiography from different perspectives and to obtain the best image after processing it, from which then can be extracted the necessary information. The complete system was built in such a way that a dental specialist may utilize it to better examine the characteristics of a patient's intraoral configuration. The system was developed with the Matlab work environment and includes a graphical user interface that the doctor may easily operate. Image - processing techniques were utilized during the development to process such an image, and the ones that proved successful will be detailed in this article. Furthermore, another aim of this system is to measure the intensity of each element of the denture, permitting a dental specialist to draw additional vital diagnoses. Some diagnoses can be identified automatically even after the raw image has been pre-processed. As a conclusion, each step executed with the software will aid in the analysis of panoramic dental radiography.

Published: October 2022

Abstract
The importance of Industry 4.0 in healthcare is obvious. Medical device manufacturing is a highly regulated field making it challenging to introduce new technologies into the manufacturing process. Computer-aided design and manufacturing technology is used to develop custom medical devices. Respiratory diseases are due to the inability of the lungs to cope with the gas exchange at rest and effort. The causes can be multiple, from stenosis of the respiratory tract to the consequences of infections with various pathogens. Spirometry is one of the main methods used in this respect. This paper aims to develop a spirometer using a Venturi tube connected to the differential pressure sensor type MPX10DP. The Venturi tube was designed using FUSION 360 and 3D printed. The pressure sensor is connected to an amplifier made with the INA118 circuit, and the ARDUINO UNO microcontroller takes the signal. The program running on the computer calculates the forced vital capacity (FVC) and forced expiratory volume in one second (FEV1).

The synergy of heterogeneous macromolecules at the cartilage-cartilage tribological interface prevents friction under quasi-static mechanical loading. Viscoelastic rheology of soft biological membrane materials, hydration lubrication, and biomechanical diffusion integrate boundary lubrication at the superficial zone. Synchronization of mechanical efficiency is viable in alignment with mechanical work, energy expenditure, and reducing oxidative stress of environmental load in urban areas. Carbon nanoparticle’s evolution from anthropogenic activities inversely influence the quality of fuel oxidation. Anisotropic fibrous honeycomb structure panel is included for trapping random environmental carbon nanoparticles/particulate matter for favourable environmental indicators.
