Published: November 2022

Abstract

Objective. The Office of Radiological Security, U.S. Department of Energy's National Nuclear Security Administration, is implementing a radiological risk reduction program which seeks to minimize or eliminate the use of high activity radiological sources, including 137Cs, by replacing them with non-radioisotopic technologies, such as x-ray irradiators. The main goal of this paper is to evaluate the equivalence of the dose delivered by gamma- and x-ray irradiators in mice using experimental measurements and Monte Carlo simulations. We also propose a novel biophantom as an in situ dose calibration method. Approach. We irradiated mouse carcasses and 3D-printed mouse biophantoms in a 137Cs irradiator (Mark I-68) and an x-ray irradiator (X-Rad320) at three voltages (160 kVp, 225 kVp and 320 kVp) and measured the delivered radiation dose. A Geant4-based Monte Carlo model was developed and validated to provide a comprehensive picture of gamma- and x-ray irradiation in mice. Main Results. Our Monte Carlo model predicts a uniform dose delivered in soft-tissue for all the explored irradiation programs and in agreement with the absolute dose measurements. Our Monte Carlo model shows an energy-dependent difference between dose in bone and in soft tissue that decreases as photon energy increases. Dose rate depends on irradiator and photon energy. We observed a deviation of the measured dose from the target value of up to −9% for the Mark I-68, and up to 35% for the X-Rad320. The dose measured in the 3D-printed phantoms are equivalent to that in the carcasses within 6% uncertainty. Significance. Our results suggest that 320 kVp irradiation is a good candidate to substitute 137Cs irradiation barring a few caveats. There is a significant difference between measured and targeted doses for x-ray irradiation that suggests a strong need for in situ calibration, which can be achieved with 3D-printed mouse biophantoms. A dose correction is necessary for bone doses, which can be provided by a Monte Carlo calculation. Finally, the biological implications of the differences in dose rates and dose per photon for the different irradiation methods should be carefully assessed for each small-animal irradiation experiment.

Published: November 2022

Abstract
In this study, a heterojunction one-transistor (1T) dynamic random-access memory (DRAM) with SiGe body/drain has been proposed and its electrical characteristics have been investigated by technology computer-aided design simulation. The results reveal that the homojunction between body and drain with a narrow band gap material enhances not only retention characteristic but also write and erase efficiencies compared to those of the structure in which SiGe is only adopted at the body region. Consequently, the sensing margin of the optimized structure is ∼15.9 and ∼2.4 times larger than that of the Si and Si0.7Ge0.3-body 1T DRAM cells, respectively, with a retention time longer than 99 ms.
Magnetic field and microstructural effects on the electrical capacitance and resistance of a quadrupolar electrical capacitor based on cotton fabrics and carbonyl iron microparticles
Authors: Bica Ioan , Mircea Anitas Eugen 
Published: November 2022

Abstract
In this work we present a procedure for manufacturing an electrical device in the form of a quadrupolar electrical capacitor (QEC). The device is based on cotton fiber fabrics with carbonyl iron (CI) microparticles and self-adhesive copper foil, and surgical tape in the form of polyacrylic fiber fabrics, as element of consolidation and electrical insulation. By using an RLC electrical bridge, the equivalent electrical capacitance (C) and resistance (R) at the two gates of the QEC are measured as a function of magnetic flux density B. It is shown that both C and R have different values at the two gates and are sensitively influenced by the magnetic field. When

, the electrical response function at the two gates has a resistive character due to magnetostriction of CI microparticles in the QEC body. For fixed voltages at one of the gates, B-dependent voltages are measured at the other gate. The structure at the two gates are quantified in terms of fractal parameters obtained from scanning electron microscopy images. The obtained characteristics shows that the obtained QEC can be used as a magnetic controllable resistor or as a magnetic field sensor for patients wearing pacemakers.
Irreversibility beyond Landauer’s principle: is it possible to perform erasure using the quantum homogenizer?
Authors: Violaris Maria , Marletto Chiara 
Published: November 2022

Abstract
Erasure is fundamental for information processing. It is also key in connecting information theory and thermodynamics, as it is a logically irreversible task. We provide a new angle on this connection, noting that there may be an additional cost to erasure, that is not captured by standard results such as Landauer’s principle. To make this point we use a model of irreversibility based on constructor theory—a recently proposed generalization of the quantum theory of computation. The model uses a machine called the ‘quantum homogenizer’, which has the ability to approximately realise the transformation of a qubit from any state to any other state and remain approximately unchanged, through overall entirely unitary interactions. We argue that when performing erasure via quantum homogenization there is an additional cost to performing the erasure step of the Szilard’s engine, because it is more difficult to reliably produce pure states in a cycle than to produce maximally mixed states. We also discuss the implications of this result for the cost of erasure in more general terms.
Unextendible and uncompletable product bases in every bipartition
Authors: Shi Fei , Li Mao-Sheng , Zhang Xiande , Zhao Qi 
Published: November 2022

Abstract
Unextendible product basis is an important object in quantum information theory and features a broad spectrum of applications, ranging from quantum nonlocality to quantum cryptography. A generalized concept called uncompletable product basis also attracts much attention. In this paper, we find some unextendible product bases that are uncompletable product bases in every bipartition, which answers a 19 year-old open question proposed by DiVincenzo et al (2003 Commun. Math. Phys.
238 379–410). As a consequence, we connect such unextendible product bases to local hiding of information, positive-partial-transpose entangled states and genuinely entangled states. Furthermore, we give a sufficient condition for the existence of an unextendible product basis that is still unextendible in every bipartition, and the existence of such a UPB is another open question proposed by Demianowic et al (2018 Phys. Rev. A 98 012313). Our results advance the understanding of the geometry of unextendible product bases.
Switchable strong coupling between dual hyperbolic phonon polaritons and photons in hybrid structure of metasurfaces and h-BN slab
Authors: Li Meiqi , Ma Qichang , Luo Aiping , Hong Weiyi 
Published: November 2022

Abstract
We propose an all-dielectric hybrid structure combined with hexagonal boron nitride slab and strontium titanate (STO) metasurfaces to excite dual hyperbolic phonon polaritons (HPhPs) and an additional optical (TO) phonon, and achieve their strong coupling with photons. The metasurfaces, supporting tunable guided-mode resonance via adjusting the external temperature, consists of STO two-dimensional grating and STO layer. Thus, the strong coupling can be switched and tuned actively between the dual HPhPs and TO phonon via adjusting the external temperature of metasurfaces. This work has numerous potential applications on multi-channel biosensors, filters and tunable source and detectors.
The impact of dual time delay and Caputo fractional derivative on the long-run behavior of a viral system with the non-cytolytic immune hypothesis

Published: November 2022

AbstractProceeding from the fact that fractional systems can better characterize the virological properties than the ordinary formulation, in the present study, we treat a Caputo fractional order viral formulation under some interesting assumptions. Our model incorporates the time delay hypothesis as well as the non-cytolytic immune mechanism and inhibition of viral replication. Analytically, we show that our enhanced delayed viral model exhibits the following three equilibria: virus-clear steady point◦, immune-free steady state1⋆, and immunity-activated steady point with the humoral feedback2⋆. By determining two critical values◦and1, the asymptotic stability of all said steady points is examined and the dynamical bifurcation associated with time delay is also explored. This theoretical arsenal provides an excellent insight into the long-run behavior of the infection. Numerically, we check the reliability of our results by highlighting the influence of fractional derivatives and time lags on the stability of steady points. We mention that our work enrich and generalize the work of Dharet al[11] by considering a general hypothetical setting.
Nonlinear Langmuir oscillations in an ultrarelativistic degenerate quantum electron-ion plasma
Authors: Khalil T H , El-Depsy A , El-Taibany W F , Selim M M 
Published: November 2022

Abstract
The investigation of the nonlinear Langmuir associations in an ultrarelativistic, fully degenerate quantum plasma, composed of stationary ions and warm electrons is considered. The quantum hydrodynamic model with the equation of state of electrons is used to derive a nonlinear differential equation that describes the chemical potential of electrons. Then, the Runge Kutta method is used to solve this equation numerically. Hence, the profiles of the chemical potential and electron number density are graphically presented. Numerical results show that the Bohm quantum force produces small scale quantum Langmuir oscillations along with the classical oscillations. These findings are helpful in understanding the features of nonlinear Langmuir waves in various astrophysical plasmas such as planetary interiors and compact objects.
Corrigendum: Spin domains in ground state of a trapped spin-1 condensate: A general study under Thomas-Fermi approximation (2020 Phys. Scr.
95 045702)
Authors: Kanjilal Projjwal K , Bhattacharyay A 
Published: November 2022

Abstract
We report some corrections in a few domain-formation diagrams arising due to a sign correction in the energy density of PM/APM states and an additional term in the energy density of MF1/MF2 states. The entire general method developed and presented for the analysis of domain formation scenarios under the Thomas-Fermi approximation remains unaffected because that is independent of energy density expressions.
Direct measurement for general quantum states using parametric quantum circuits
Authors: Wang Zhiyuan , Zhang Zijing , Zhao Yuan 
Published: November 2022

Abstract
In the field of quantum information, the acquisition of information for unknown quantum states is very important. When we only need to obtain specific elements of a state density matrix, the traditional quantum state tomography will become very complicated, because it requires a global quantum state reconstruction. Direct measurement of the quantum state allows us to obtain arbitrary specific matrix elements of the quantum state without state reconstruction, so direct measurement schemes have obtained extensive attention. Recently, some direct measurement schemes based on weak values have been proposed, but extra auxiliary states in these schemes are necessary and it will increase the complexity of the practical experiment. Meanwhile, the post-selection process in the scheme will reduce the utilization of resources. In order to avoid these disadvantages, a direct measurement scheme without auxiliary states is proposed in this paper. In this scheme, we achieve the direct measurement of quantum states by using quantum circuits, then we extend it to the measurement of general multi-particle states and complete the error analysis. Finally, when we take into account the dephasing of the quantum states, we modify the circuits and the modified circuits still work for the dephasing case.
Leptoquark and vector-like quark extended model for simultaneousexplanation of W boson mass and muon g–2 anomalies*
Authors: He Shi-Ping 
Published: November 2022

Abstract
The CDF collaboration recently announced a new measurement result for the W boson mass, and it is in tension with the standard model prediction. In this paper, we explain this anomaly in the vector-like quark (VLQ)

and leptoquark (LQ)

extended model. In this model, both the VLQ and LQ have positive corrections to the W boson mass. Moreover, it may be a solution to the

anomaly because of the chiral enhancements from top, T, and B quarks.
Classifying Globular Clusters and Applying them to Estimate the mass of the Milky Way
Authors: Sun GuangChen , Wang Yougang , Liu Chao , Long Richard J. , Chen Xuelei , Gao Qi 
Published: November 2022

Abstract
We combine the kinematics of 159 globular clusters (GCs) provided by the Gaia Early Data Release 3 (EDR3) with other observational data to classify the GCs, and to estimate the mass of the Milky Way (MW). We use the age–metallicity relation, integrals of motion, action space and the GC orbits to identify the GCs as either formed in situ (Bulge and Disk) or ex situ (via accretion). We find that 45.3% have formed in situ, while 38.4% may be related to known merger events: Gaia-Sausage-Enceladus, the Sagittarius dwarf galaxy, the Helmi streams, the Sequoia galaxy and the Kraken galaxy. We also further identify three new sub-structures associated with the Gaia–Sausage–Enceladus. The remaining 16.3% of GCs are unrelated to the known mergers and thought to be from small accretion events. We select 46 GCs which have radii 8.0 < r < 37.3 kpc and obtain the anisotropy parameter

, which is lower than the recent result using the sample of GCs in Gaia Data Release 2, but still in agreement with it by considering the error bar. By using the same sample, we obtain the MW mass inside the outermost GC as

Detection and discrimination of electrical stimuli from an upper limb cuff electrode in M. Mulatta
Authors: Schlichenmeyer T C , Zellmer E R , Burton H , Ray W Z , Moran D W 
Published: November 2022

Abstract

Objective. Peripheral nerve interfaces seek to restore nervous system function through electrical stimulation of peripheral nerves. In clinical use, these devices should function reliably for years or decades. In this study, we assessed evoked sensations from multi-channel cuff electrode stimulation in macaque monkeys up to 711 d post-implantation. Approach. Three trained macaque monkeys received multi-channel cuff electrode implants at the median or ulnar nerves in the upper arm. Electrical stimuli from the cuff interfaces evoked sensations, which we measured via standard psychophysical tasks. We adjusted pulse amplitude or pulse width for each block with various electrode channel configurations to examine the effects of stimulus parameterization on sensation. We measured detection thresholds and just-noticeable differences (JNDs) at irregular, near-daily intervals for several months using Bayesian inferencing from trial data. We examined data trends using classical models such as Weber’s Law and the strength-duration relationship using linear regression. Main results. Detection thresholds were similar between blocks with pulse width modulation and blocks with pulse amplitude modulation when represented as charge per pulse, the product of the amplitude and the pulse width. Conversely, Weber fractions—calculated as the slope of the regression between JND charge values and reference stimulus charge—were significantly different between pulse width and pulse amplitude modulation blocks for the discrimination task. Significance. Weber fractions were lower in blocks with amplitude modulation than in blocks with pulse width modulation, suggesting that pulse amplitude modulation allows finer resolution of sensory encoding above threshold. Consequently, amplitude modulation may enable a greater dynamic range for sensory perception with neuroprosthetic devices.

Published: November 2022

Abstract
Three-dimensional profile measurement system is designed based on the Cortex-M3 series processor. Firstly, a digital low pass filter first is design high performance and low computational cost. Then the output signals from the acceleration sensor, magnetic sensor and gyro are sampled and filtered and a signal modulation circuit is designed to process the signal of gyro, which can improve the efficiency of the sensitive device and effectively suppress the zero drift caused by the device itself. Therefor the stability of the three-dimensional profile measurement system is improved greatly.

Published: November 2022

Abstract
Peri-implant infection remains one of the greatest threats to orthopedics. The construction of bone implants with good antibacterial and osteogenic properties is beneficial for reducing the risk of implant-related infections and healing bone defects. In this study, N-halamine coating (namely N–Cl) was grafted onto alkali-heat treated titanium (Ti) using polydopamine to endow Ti-based orthopedic implants with strong bactericidal activity. Surface characterization revealed that the N–Cl coating has porous structure loaded with active chlorine (Cl+). The N–Cl coating also provided micro/nano-structured Ti surfaces with excellent antibacterial ability via transformation between N–H and N–Cl, and approximately 100% disinfection was achieved. Furthermore, the as-prepared N–Cl coating exhibited good biocompatibility and osteogenesis ability in vitro. These results indicate that applying N–Cl coatings on Ti could prevent and treat peri-implant infections.
Reanalysis-based contextualization of real-time snow cover monitoring from space
Authors: Gascoin Simon , Monteiro Diego , Morin Samuel 
Published: November 2022

Abstract
Satellite remote sensing provides real-time information on the extent of the snow cover. However, the period of record is generally too short to build a reference climatology from these data alone, preventing their use as climatic indicators. Here we show that reanalysis data can be used to reconstruct a 30 year snow cover time series that fits well with the satellite observations. This climatology can then be used to put the current state of the snow cover into perspective. We implemented this approach to provide real-time information on the snow cover area in the Alps through a web application.
Painlevé I and exact WKB: Stokes phenomenon for two-parameter transseries
Authors: van Spaendonck Alexander , Vonk Marcel 
Published: November 2022

AbstractFor more than a century, the Painlevé I equation has played an important role in both physics and mathematics. Its two-parameter family of solutions was studied in many different ways, yet still leads to new surprises and discoveries. Two popular tools in these studies are the theory of isomonodromic deformation that uses the exact WKB method, and the asymptotic description of transcendents in terms of two-parameter transseries. Combining methods from both schools of thought, we follow work by Takei and collaborators to formulate complete, two-parameter connection formulae for solutions when they cross arbitrary Stokes lines in the complex plane. These formulae allow us to study Stokes phenomenon for the full two-parameter family of transseries solutions. In particular, we recover the exact expressions for the Stokes data that were recently found by Baldino, Schwick, Schiappa and Vega and compare our connection formulae to theirs. We also explain several ambiguities in relating transseries parameter choices to actual Painlevé transcendents, study the monodromy of formal solutions, and provide high-precision numerical tests of our results.
tt∗ Toda equations for surface defects in SYM and instanton counting for classical Lie groups
Authors: Bonelli Giulio , Globlek Fran , Tanzini Alessandro 
Published: November 2022

AbstractThe partition function ofsuper Yang-Mills theories with arbitrary simple gauge group coupled to a self-dual Ω background is shown to be fully determined by studying the renormalization group equations relevant to the surface operators generating its one-form symmetries. The corresponding system of equations results in anon-autonomousToda chain on the root system of the Langlands dual, the evolution parameter being the RG scale. A systematic algorithm computing the full multi-instanton corrections is derived in terms of recursion relations whose gauge theoretical solution is obtained just by fixing the perturbative part of the IR prepotential as its asymptotic boundary condition for the RGE. We analyze the explicit solutions of theτ-system for all the classical groups at the diverse levels, extend our analysis to affine twisted Lie algebras and provide conjectural bilinear relations for theτ-functions of linear quiver gauge theory.
