Abstract
Glucose oxidase-mediated starvation therapy that effectively cuts off energy supply holds great promise in cancer treatment. However, high glutathione (GSH) contents and anoxic conditions severely reduce therapy efficiency and cannot fully kill cancer cells. Herein, to resolve the above problem, this study constructed a biomimetic nanosystem based on nanreproo-MnO2 with porous craspedia globose-like structure and high specific surface area, and it was further modified with dopamine and folic acid to guarantee good biocompatibility and selectivity toward cancer cells. This nanosystem responsively degraded and reacted with GSH and acid to regenerate O2, which significantly increased intracellular O2 levels, accelerated glucose consumption, and improved starvation therapy efficiency. Moreover, anticancer drug of camptothecin was further loaded, and notably enhanced cancer growth inhibition was obtained at very low drug concentrations. Most importantly, this novel therapy could unprecedentedly inhibit cancer cell migration to a very low ratio of 19%, and detailed cell apoptosis analyses revealed late stage apoptosis contributed most to the good therapeutic effect. This work reported a new train of thought to improve starvation therapy in biomedicine, and provided a new strategy to design targeted nanocarrier to delivery mixed drugs to overcome the restriction of starvation therapy and develop new therapy patterns.

Abstract
This paper describes the first persistent-mode medium magnetic field (400 MHz; 9.39 T) nuclear magnetic resonance (NMR) magnet which uses superconducting joints between high-temperature superconductors (HTSs). As the ultimate goal, we aim to develop a high-resolution 1.3 GHz (30.5 T) NMR magnet operated in the persistent-mode. The magnet requires superconducting joints between HTSs and those between an HTS and a low-temperature superconductor (LTS). Towards this goal, we have been developing persistent-mode HTS inner coils to be operated in a 400 MHz (9.39 T) NMR magnet and here we present the first prototype inner coil wound with a single piece (RE = rare earth)Ba2Cu3O7−x
(REBCO) conductor. The coil and a REBCO persistent current switch are connected with intermediate grown superconducting joints with high critical currents in external magnetic fields. To evaluate the performance of the joints in an ultimately stable and homogeneous magnetic field, the coil is operated in the persistent-mode, generating 0.1 T, in a 9.3 T background magnetic field of a persistent-mode LTS outer coil. The magnetic field drift over two years of the 400 MHz LTS/REBCO NMR magnet is as small as ∼1 ppm, giving high-resolution NMR spectra. The magnetic field drift rate over the second year was 0.03 × 10−3 ppm h−1, which is more than three orders of magnitude smaller than that required for an NMR magnet, demonstrating that the superconducting joints function satisfactorily in a high-resolution NMR system. The corresponding joint resistance is inferred to be <10−14 Ω.

Abstract

Context. Long-term deep brain stimulation (DBS) studies in rodents are of crucial importance for research progress in this field. However, most stimulation devices require jackets or large head-mounted systems which severely affect mobility and general welfare influencing animals’ behavior. Objective. To develop a preclinical neurostimulation implant system for long-term DBS research in small animal models. Approach. We propose a low-cost dual-channel DBS implant called software defined implantable platform (STELLA) with a printed circuit board size of Ø13 × 3.3 mm, weight of 0.6 g and current consumption of 7.6 µA/3.1 V combined with an epoxy resin-based encapsulation method. Main results. STELLA delivers charge-balanced and configurable current pulses with widely used commercial electrodes. While in vitro studies demonstrate at least 12 weeks of error-free stimulation using a CR1225 battery, our calculations predict a battery lifetime of up to 3 years using a CR2032. Exemplary application for DBS of the subthalamic nucleus in adult rats demonstrates that fully-implanted STELLA neurostimulators are very well-tolerated over 42 days without relevant stress after the early postoperative phase resulting in normal animal behavior. Encapsulation, external control and monitoring of function proved to be feasible. Stimulation with standard parameters elicited c-Fos expression by subthalamic neurons demonstrating biologically active function of STELLA. Significance. We developed a fully implantable, scalable and reliable DBS device that meets the urgent need for reverse translational research on DBS in freely moving rodent disease models including sensitive behavioral experiments. We thus add an important technology for animal research according to ‘The Principle of Humane Experimental Technique’—replacement, reduction and refinement (3R).

Low energy cross section of 18O(p,γ)19F
Authors: Best A. , Pantaleo F. R. 
Published: September 2021

Abstract
The observation of oxygen isotopes in giant stars sheds light on mixing processes operating in their interiors. Due to the very strong correlation between nuclear burning and mixing processes it is very important to reduce the uncertainty on the cross sections of the nuclear reactions that are involved. In this paper we focus our attention on the reaction 18O(p,γ)19F. While the 18O(p, α)15N channel is thought to be dominant, the (p,γ) channel can still be an important component in stellar burning in giants, depending on the low energy cross section. So far only extrapolations from higher-energy measurements exist and recent estimates vary by orders of magnitude. These large uncertainties call for an experimental reinvestigation of this reaction.
We present a direct measurement of the 18O(p,γ)19F cross section using a high-efficiency 4π BGO summing detector at the Laboratory for Underground Nuclear Astrophysics (LUNA). The reaction cross section has been directly determined for the first time from 140 keV down to 85 keV and the different cross section components have been obtained individually. The previously highly uncertain strength of the 90 keV resonance was found to be three orders of magnitude lower than an indirect estimate based on nuclear properties of the resonant state and a factor of 20 lower than a recently established upper limit. This result excludes the possibility that the 90 keV resonance can contribute significantly to the stellar reaction rate.
In addition the strengths and branching ratios of resonances between 150 and 400 keV have been determined with much improved precision and sensitivity using a HPGe detector, including a first measurement of branching ratios of the 216 keV resonance. Preliminary results are presented.

Temperature Profile of Hollow Aluminum Heated using Thermoelectric on Both Sides
Authors: Zafirah T N , Triqadafi A O , Kamasi D D , Sakti S P 
Published: September 2021

Abstract
The use of QCM sensors for gas sensors requires a reaction space known as headspace. Gas sensor headspace is needed to be heated to enable the gas molecule to react with the sensor sensitive layer. In the development of a sensor array, sensor placement requires space. As a result, the sensor experiences a temperature condition influenced by the sensor’s placement. Our headspace was made of a rectangular aluminum hollow. The hollow dimension was 40mm in height and 20mm in width with an aluminum thickness of 1mm. The aluminum hollow was heated on two sides using two thermoelectric TEC-12706. The temperature distribution of the aluminum heated by thermoelectric on both sides shows the temperature distribution profile, which depends on its position towards the thermoelectric. At the elevated temperature of 80°C, aluminum’s surface temperature shows a uniform temperature distribution in the direction perpendicular to the thermoelectric surface. In the direction parallel to the thermoelectric surface, the temperature profile shows a curved curve with the thermoelectric midpoint’s highest temperature. The temperature difference between the point parallel to the midpoint and the thermoelectric edge is 5°C. A temperature difference of less than 1°C is only obtained in an area 1cm wide from the thermoelectric midpoint position. This result suggests that a wider thermoelectric surface should be considered to obtain a wider area with uniform temperature.
Can a hidden-variable-based system violate Bell’s inequality?
Authors: Bahnasy Mahmoud 
Published: September 2021

Abstract
Quantum mechanics predicts faster-than-light information transportation in order to satisfy quantum entanglement experimental results. Such a prediction violates the locality principle and Bell’s inequality. Quantum mechanisms also state that the world is intrinsically probabilistic. Such an idea was not welcome by many scientists including Einstein, Podolsky and Rosen. To resolve such a dilemma, the ”Many-world” theory was presented by Hugh Everett in 1975. Such a theory asserts that the universal wave function is real and that there is no wave function collapse. Also, it states that all possible outcomes of quantum measurements are physically realized in other parallel universes. Besides, in quantum mechanics, the observer effect defines a state transition of quantum objects. Such a phenomenon affirms that quantum objects behave differently depending on being observed or not.
In this paper, we present few assumptions based on which we build a classical hidden-variable-based system that can violate Bell’s inequality. Therefore, adopting similar assumptions in explaining quantum entanglement could lead to a better explanation of quantum mechanics without violating the locality principle or adopting such weird assumptions. Hence, one can conclude that extending Quantum Mechanism by a set of similar hidden variables can resolve such a paradox and predict the quantum entanglement experimental results without violating the locality principle.

Abstract
This paper explores dynamic equations. Dynamic equation has been well researched and developed for centuries. It has applied to a wide variety of fields such as physics, biology, chemistry, engineering, economics, history, and medicine, etc, with significant impacts on human society. A most common and stereotypical example of a dynamic equation is logistic equation. In this paper the logistic equation is thoroughly analysed and discussed about its convergence over a number series at fixed points given different variable ranges. Furthermore, a powerful and tricky theorem of dynamic equation, Coppel’s Theorem, is proved: any dynamic equation series in 0 and 1 without 2-cycles will converge. The proof is difficult but creative and artistic.

The fuzzy regression method can be used for fitting the fuzzy data for the construction of the simple linear regression model. This paper aims to study the performance and compare the adaptive fuzzy method and traditional fuzzy method by using the criteria of mean square error (MSE) and the coefficient of determine R
2. A Monte Carlo simulation with 5,000 iterations was performed to achieve the objective of research. In simulations, the independent variable has a gamma distribution with the parameters are α = 4, 5, 6 and β = 1. We carried out simulations to examine the performance of MSE from the adaptive fuzzy regression model and the traditional fuzzy regression model. The results showed that the transformation of independent variable with gamma distribution to be a normal distribution make the simple linear regression by the adaptive fuzzy method outperforms the traditional fuzzy method. In terms of MSE, the adaptive fuzzy method performed better than the traditional fuzzy method. In addition, the values of coefficient of determine from the adaptive fuzzy method and the traditional fuzzy method are slightly different.

Authors: Ou Wenhao , Li Mengxuan , Liu Bin , Liu He 
Published: September 2021

Abstract
The change of foundation, line galloping and vibration will cause the change of the stress state of the tower. By monitoring the stress state of the tower, the accidents such as tower collapse and tower collapse can be forewarned in time. In view of the shortcomings of the existing tower stress monitoring device, such as inconvenient data collection and low measurement efficiency, this paper proposes a high-precision strain sensor chip and RFID technology-based strain sensor to monitor the tower strain. According to the characteristics of strain sensor collection unit and RFID technology, a low-power strain sensor for real-time monitoring of strain data of transmission towers was designed. It can be read and recorded by hand-held reader, which improves the collection efficiency of strain information of towers and reduces the manual operation. In view of the shortage of energy supply of transmission line sensors, the power consumption design extends the effective working time of the sensor.
Shooting-projection method for a small object moving under the influence of a force

Published: September 2021

Abstract
We consider a small object in 3D moving under the influence of a force that may depend explicitly on time, on the position of the object, and on its velocity. The equations of motion of classical mechanics are assumed to hold. If the position of the object is specified at some initial and some final time, obtaining the trajectory of the object requires the solution of a two-point boundary value problem. To solve the problem various numerical technics can be applied. This paper extends the recently proposed shooting-projection method to 3D. We introduce a Lagrangian from which, applying the principle of least action, the projection trajectory is derived. Analysis of the action reveals the meaning of the projection trajectory. Using the shooting-projection method, the considered two-point boundary value problem is solved for the case of a projectile motion in the presence of air resistance and wind.

Published: September 2021

Abstract
Chinese settlements in Lasem along the north coast of Java were the result of trading activities. The open-mindedness of Javanese people in coastal areas led to acculturation process between Javanese locals and Chinese immigrants that formed a new culture, including the architecture of Chinese-style houses in Lasem. The Chinese-style houses’ architecture has specific characteristics as the result of the cultural blend. This study aims to identify these characteristics, specifically the characteristics of Javanese architecture in the architecture of Chinese-style houses in Lasem. The method used in this study is qualitative descriptive method by aligning the acculturation theories with the architecture of Chinese-style houses in Lasem. The study concludes that there was a process of acculturation between Javanese and Chinese architecture that can be found in the ornaments, materials, and layout.
Research of the effect of droplets deformation on the radar characteristics of rains
Authors: Sozaeva L T , Zhaboeva M M 
Published: September 2021

AbstractThe results of calculations of the radar characteristics of rains for the averaged spectra of drops specific to the North Caucasus are presented. The results are obtained under the assumption that the droplets are deformed when falling in clouds and precipitation, taking the form of a flattened spheroid. For comparison, the radar characteristics calculated by the Mi algorithm for spherical droplets are given. For individual large droplets, which under the influence of an electric field can take extreme sizes, the reflectivity are also calculated. The analysis of the obtained results showed that when reconstructing the microstructural characteristics of hail clouds and precipitation at high intensities, it is necessary to take into account the shape of drops.

Published: September 2021

AbstractThis article presents the results of laboratory experiments on testing of equipment and methods for determining the specific charge on reagent particles formed during the sublimation of the AgI and the AD-1 pyrocomposition. The method for measuring charged particles is based on the use of the deflection of reagent particles in the electric field of a flat capacitor. Preliminary results obtained in the course of research made it possible to establish that when pyrotechnic compositions are sublimated in the electric field of a flat capacitor with polarity «0», «+», the reagent particles are charged negatively, and when using a capacitor with polarities «0», «–», the particles of the reagent are charged positively. When using a bipolar capacitor, the particles are charged both positively and negatively, the ratio between negative and positively charged particles is 7:3.

Published: September 2021

AbstractThe article examines the methodical aspects of the integrated use of passive and active radar to improve early warning methods for the development of powerful convective clouds and thunderstorm processes. Some results of complex experimental studies of the atmosphere and convective clouds in the Leningrad region are presented with the use of meteorological radar and ground-based microwave radiometers. Particular attention is paid to the use of microwave radiometry to separate the content of vapor moisture in the atmosphere and liquid water in the clouds, as well as the use of a comprehensive method of passive-active radar to determine the super cool water of powerful convective clouds. Prospects for improving technologies for predicting weather hazards associated with clouds and precipitation are connected with the use of a complex of radiophysical means of the Geophysical Observatory of the Mozhaisky Military Space Academy.

Published: September 2021

Abstract
40 hail and hail-hazardous clouds of various strengths were considered, which were seeded with the help of a glaciogenic agents in order to prevent and interrupt hail. An unseeded control cloud was matched for each seeded cloud. For this, the parameter dV35 was used – the volume of the radio echo of the cloud with a reflectivity of more than 35 dBZ above the level of zero isotherm. A cloud was considered to be a control cloud if at the time of the beginning of seeding and 10 minutes before that dV35 differs by no more than 15% from the same value of the seeded cloud. To assess the possible impact of seeding, the radar characteristics of pairs of seeded and control clouds were analyzed. It was found that in the seeded clouds the average, maximum and minimum values of the maximum reflectivity, the height of the upper boundary, the vertically integrated water content, the intensity of precipitation and dV35 are higher, and the height of the maximum reflectivity is slightly lower than the similar values of the control clouds.
