Joint Damage Identification in Frame Structures by Integrating a New Damage Index with Equilibrium Optimizer Algorithm

Beam-column joints are responsible for maintaining the integrity and stability of frame structures, and any damage to these critical components can endanger the overall safety and reliability of the structure. Hence, early detection of structural joint damage is of paramount importance. However, most of the available structural damage identification methods focus on identifying damage in structural members, and relatively fewer methods have been developed so far for assessing damage in structural joints. In view of this, the present study proposes a new two-stage method for joint damage identification of frame structures. In the first stage, an efficient damage indicator, called residual moment-based joint damage index (RMBJDI), is developed and applied to detect the location of potentially damaged joints. This damage indicator can help to reduce the number of involved damage variables by excluding healthy joints from the problem. In the second stage, the reduced dimension damage identification problem is formulated as an optimization problem and is further tackled by employing a robust meta-heuristic algorithm, namely equilibrium optimizer (EO), to determine the damage severity of suspected damaged joints. In order to assess the capability and effectiveness of the presented joint damage identification method, two numerical examples of frame structures are conducted under both noise-free and noisy conditions. The results demonstrate that the proposed two-stage method, which integrates RMBJDI with EO, is a highly accurate and powerful tool for localizing and quantifying the joint damage in frame structures.
Treatment of Seborrheic Keratosis by High Frequency Focused Ultrasound – An Early Experience with 11 Consecutive Cases

Purpose High intensity focused ultrasound operating at 20 MHz has been demonstrated as a safe and efficient treatment modality for a range of dermatological indications. The method is potentially also applicable to removal of seborrheic keratosis. Patients and Methods A total of 54 seborrheic keratoses in 11 volunteer subjects (8 women and 3 men, average age 51.5 ± 13.2 years) were treated in a single session with a medical 20 MHz high intensity focused ultrasound device developed for dermatological conditions. Handpieces with nominal focal depths of 0.8 mm below the skin surface were used to administer acoustic energy of 0.99–1.2 J/dose. An integrated dermoscope in the handpiece was used to monitor the treatment in real-time. Treatment efficacy and side-effects were assessed directly after treatment and at follow-up 4–15 weeks after treatment. Results The treatment showed positive results in 96.3% of the cases. About 68.5% of the cases were classified as complete response and 27.8% of the cases as partial response. Two cases (3.7%) did not respond to treatment and were classified as stable condition. No subjects experienced worsening of their condition, and no treatment received the classification of progressive condition. Side effects were primarily redness in the treatment area due to superficial telangiectasia, mild scarring, and persisting and slow-healing lichen planus-like keratosis. No adverse events were observed. Conclusion HIFU is concluded to be a safe and efficient skin treatment for seborrheic keratoses. It has advantages over conventional treatments that can lead to pain during treatment and scarring after healing.

Majority and Minority Carrier Traps in NiO/β-Ga2O3 p+-n Heterojunction Diode

Identifying defects/traps is of vital importance for the implementation of high-performance Ga<sub>2</sub>O<sub>3</sub> power devices. In this work, majority and minority carrier traps in beta-gallium oxide (<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub>) have been investigated and identified by means of deep level transient spectroscopy (DLTS) in Ni/<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub> Schottky barrier diode (SBD) and NiO/<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub> p<sup>+</sup>-n heterojunction diode (HJD). For both diodes, a dominant energy level of majority carrier (electron) trap states is determined to be <inline-formula> <tex-math notation="LaTeX">${E}_{C}-$ </tex-math></inline-formula>(0.75–0.79) eV with a concentration of (2.4–4.1) <inline-formula> <tex-math notation="LaTeX">$\times 10^{{13}}$ </tex-math></inline-formula> cm<inline-formula> <tex-math notation="LaTeX">$^{-{3}}$ </tex-math></inline-formula>. Meanwhile, an additional trapping level at <inline-formula> <tex-math notation="LaTeX">${E}_{V} +0.14$ </tex-math></inline-formula> eV with a concentration of 1.2 <inline-formula> <tex-math notation="LaTeX">$\times 10^{{14}}$ </tex-math></inline-formula> cm<inline-formula> <tex-math notation="LaTeX">$^{-{3}}$ </tex-math></inline-formula> yield is present in NiO/<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub> bipolar HJD but absent in the Ni/<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub> SBD unipolar counterpart. The detection of such minority carrier traps originates from the hole injection through trap-assisted tunneling (TAT) from <inline-formula> <tex-math notation="LaTeX">$\text{p}^{+}$ </tex-math></inline-formula>-NiO to <inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub>. The bias- and frequency-dependent DLTS characteristics identify that such shallow-level minority carrier traps are located in the <inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub> bulk region rather not interfacial states at the NiO/<inline-formula> <tex-math notation="LaTeX">$\beta $ </tex-math></inline-formula>-Ga<sub>2</sub>O<sub>3</sub> heterointerface. The identification of both majority and minority carrier traps in this work may shed light on the in-depth understanding of carrier transport mechanisms in Ga<sub>2</sub>O<sub>3</sub>-based unipolar and bipolar power devices.

IMPACT OF INDUSTRIALIZATION ON THE DYNAMICS OF ATMOSPHERIC CARBON DIOXIDE: A MODELING STUDY

The expansion of the industrial sector is one of the prime contributors to the increase in the concentration of heat-trapping gases, mainly carbon dioxide ([Formula: see text]), in the atmosphere. Since the onset of the industrial revolution, industrial [Formula: see text] emissions have been contributing significantly to global warming and associated climate changes. To design strategies for the mitigation of climate changes, it is crucial to comprehend the role of industrialization in the elevation of atmospheric [Formula: see text] concentration. This paper presents a nonlinear mathematical model, comprising a set of nonlinear differential equations, to examine the impact of industrialization on the dynamics of atmospheric [Formula: see text]. Analysis of the model shows that if the industrial [Formula: see text] emission rate increases beyond a critical value, the system experiences Hopf-bifurcation about the interior equilibrium and periodic solution is generated. The direction and stability of periodic solutions arising through Hopf-bifurcation are investigated. Numerical simulation is presented to demonstrate the analytical findings.
Optimization of Non-Binary LDPC Coded Massive MIMO Systems With Partial Mapping and REP Detection

In this work, a non-binary low density parity check (LDPC) coded high dimensional multiple input multiple output (MIMO) scheme with partial mapping for high order modulation is proposed. For the proposed scheme, when <inline-formula> <tex-math notation="LaTeX">$M$ </tex-math></inline-formula>-ary quadrature amplitude modulation (QAM) is employed, then non-binary LDPC code constructed over Galois field with order <inline-formula> <tex-math notation="LaTeX">$\sqrt {M}$ </tex-math></inline-formula> is used for partial mapping, where <inline-formula> <tex-math notation="LaTeX">$\sqrt {M}$ </tex-math></inline-formula> is an integer. At the receiver side, a real-valued expectation propagation (REP) based detection algorithm is used to couple with the non-binary decoder seamlessly. Meanwhile, the symbol-wise <italic>a-priori</italic> information returned by the non-binary decoder is used to aid the REP detection. Furthermore, a symbol-wise extrinsic information transfer (SEXIT) chart based iterative optimization algorithm is used to optimize the concatenated non-binary LDPC code. This work proposed to model the <italic>a-priori</italic> information of non-zero codes/symbols of detector/decoder as the output of a cyclic-symmetric additive white Gaussian noise (AWGN) channel and a simplified method based on interpolation is proposed to calculate the component-EXIT chart of the REP-detector for massive MIMO. The proposed method can facilitate the optimization and avoid a large amount of simulations. Both SEXIT chart based analysis and numerical simulation results demonstrate the validity of the above idea.
Energy-based modeling and Hamiltonian LQG control of a flexible beam actuated by IPMC actuators

The control of a flexible beam using ionic polymer metal composites (IPMCs) is investigated in this paper. The mechanical flexible dynamics are modelled as a Timoshenko beam. The electric dynamics of the IPMCs are considered in the model. The port-Hamiltonian framework is used to propose an interconnected control model of the mechanical flexible beam and IPMC actuator. Furthermore, a passive and Hamiltonian structure-preserving linear quadratic Gaussian (LQG) controller is used to achieve the desired configuration of the system, and the asymptotic stability of the closed-loop system is shown using damping injection. An experimental setup is built using a flexible beam actuated by two IPMC patches to validate the proposed model and show the performance of the proposed control law.
Learning language

Interpreting what you hear through the medium of speech sounds is in many ways just like interpreting what you see through the medium of the structured light that strikes your eyes. Understanding descriptive speech is closely akin to perception of the world through vision, ordinary hearing or touch. This, plus a flexible view of the different ways in which one mind can take account of another, helps to explain how children can learn tens of thousands of words without special instruction and without requiring a 'theory of mind.

Meteorological Conditions Favorable for Strong Anthropogenic Aerosol Impacts on Clouds

Ship‐track‐like polluted cloud tracks provide a direct way to study aerosol‐cloud interactions. Here, we study environmental conditions favorable for pollution tracks' formation. We study polluted cloud tracks forming downwind of localized anthropogenic air pollution hot spots of Norilsk and Cherepovets in Russia and Thompson in Canada. Polluted cloud tracks form on 20%–37% of days with liquid‐phase clouds. The large‐scale atmospheric circulation largely determines the occurrence of track‐favoring conditions. Tracks tend to form in clean and thin clouds under stable and dry conditions that are more often associated with anticyclonic large‐scale flow in the studied locations.
Channel Characteristics Analysis of Galvanic Coupling Intra-Body Communication

Intra-Body Communication (IBC), which employs the human body as the channel to transmit health informatics, is a potential approach for connecting wearable and implantable devices. Undoubtedly, its channel characteristics provide deep insights to select parameters that are beneficial for the physical layer design of the Body Area Network (BAN). Nevertheless, such analysis has not been systematically addressed. To this end, the transfer function from the quasi-static model in the electromagnetic field is considered at first. Then, the linearity of the galvanic coupling IBC channel is verified. Besides, the proper frequency band for data transmission is investigated using the water-filling algorithm. Moreover, the theoretical Bit Error Rate (BER) performances of different modulations are studied. Results revealed that the galvanic coupling IBC channel can be modeled as a linear band-limited Additive White Gaussian Noise (AWGN) channel. Finally, suitable modulations for various scenarios are discussed based on the channel characteristics found. Consequently, this work can further enrich the design of the IBC for medical applications.
Hepatotoxic products of cyanobacteria and their toxicological effects

Chronic human exposure to water contaminated with hepatotoxic cyanobacterial compounds (cyanotoxins) can lead to an increased incidence of hepatocellular carcinoma or other forms of liver disease. Humans can be exposed to cyanotoxins through ingestion, inhalation and dermal contact, i.e. by using contaminated drinking water, recreational water, water used for hemodialysis or via food. Among hepatotoxic cyanotoxins, cyclic peptides microcystins and nodularin should be emphasized, as well as the tricyclic alkaloid cylindrospermopsin. In addition, the existence of a new hepatotoxic cyanobacterial secondary metabolite, called limnotrixin, has been investigated in recent years. Due to the different chemical structures of these cyanotoxins, mechanisms of their toxic effects also differ. Globally, hepatotoxins are the most common cyanobacterial toxins and, among them, microcystins are the most frequently detected during cyanobacterial blooms and also the most extensively studied. The latter is also the case in the Republic of Serbia, where cases of cyanobacterial blooms in water bodies used for water supply are mostly related to species that are potential microcystin producers (e.g. representatives of the genera Microcystis and Planktothrix). Additionally, microcystins are the only group of hepatotoxic cyanotoxins for which regular monitoring has been established in our country, which primarily refers to the water bodies used as water supply sources. However, since there is an increased frequency of cyanobacterial blooming, both worldwide and in our country, it is very important to monitor potential risks and understand the toxicity and potential carcinogenicity of hepatotoxic products of cyanobacteria, which was the main aim of this study
Energy Efficiency Optimization for Rate-Splitting Multiple Access-Based Indoor Visible Light Communication Networks

With the explosive proliferation of connected devices and mobile users in the Internet-of-things, multiple access techniques are urged to be developed for the next generation wireless communications. Recently, rate-splitting multiple access (RSMA) has been a promising communication technology that holds advantages of strong robustness, low complexity, and high spectral efficiency, which can be integrated with the indoor visible light communication (VLC) broadcast system to compensate for the shortcomings of limited modulation bandwidth of LEDs. However, the research on the RSMA-based VLC systems is still in its infancy and there exist various problems to be explored. To benefit from the RSMA technique, this paper investigates the energy efficiency optimizations for both single-cell and multi-cell RSMA-based VLC broadcast systems. Specifically, these two systems are modeled, where the VLC broadcast channel follows Lambertian radiation model, and the splitting design and successive interference cancellation of RSMA are employed to mitigate the multi-user interference. Especially for multi-cell networks, the zero-forcing approach is adopted to eliminate the inter-cell interference. To maximize the energy efficiency, the precoding and power allocation problems are formulated for single-cell and multi-cell networks while accommodating multiple constraints including dynamic operation ranges of LEDs, QoS requirements, and interference elimination. For solving these non-convex fractional problems, two pieces of successive convex approximation (SCA)-based algorithms are proposed, in which the variable transformation and linear approximation are adopted. Simulation results indicate that the proposed schemes can achieve superior energy efficiency with fast convergence for various network loads and user deployments.
Effect of solvents and temperature on the structural, thermodynamic and electronic properties of capped phenylalanine: A computational study

Effects of solvents and temperature on the structural, thermodynamic, and electronic properties of L-configuration of N-acetyl-phenylalaninyl amide (NAPA) were studied using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) approach. Enthalpy (H), entropy (S) and specific heat capacity (Cv) were found to increase with the increase of temperature (100 K-1600 K) because of the increasing intensities of molecular vibration. On the contrary, Gibb’s free energy (G) was found to decrease with the increase of temperature. The UV-light absorption maximum, λmax, is red-shifted in the presence of polar protic, aprotic and non-polar solvents. On the other hand, calculation shows that dipole moment in polar solvents (protic and aprotic), non-polar solvents, and the gas phase are ~3.35, ~3.0, and 2.5 D, respectively. However, no significant change was found in the HOMO-LUMO energy gap in the presence of different types of solvents. J. Bangladesh Acad. Sci. 45(2); 205-215: December 2021
Development of tools for SALT/RSS spectropolarimetry reductions: application to the blazar 3C279

Blazars represent a subset of AGN with relativistic jets, where the direction of the jet lies very close to our line of sight. The highly Doppler boosted emission from the blazar’s jet results in high apparent luminosities, and blazars display variability on periods from less than one day up to years. At optical wavelengths, the observed emission of the blazar is a superposition of the polarised non-thermal synchrotron emission, arising from the jet, and the unpolarised thermal emission, arising from the accretion disc, broad line region, torus and host galaxy. Polarimetry observations can serve as an important tool for diagnosing the emission from blazars. The RSS spectrograph, on SALT, can operate in spectropolarimetry mode and is currently being used to undertake spectropolarimetric observations of transient blazar sources. We present additional tools developed to work in conjunction with the current SALT spectropolarimetry reduction pipeline, polsalt, that aims to streamline the reduction of the SALT polarisation data, including the testing of the wavelength calibration of the individual O and E beams. This was applied to observations of 3C 279 during 2017.
Quantitative Research on Reinforced Concrete Performance Index of Reinforced Concrete Bridge Column

According to the failure characteristics of reinforced concrete(RC) bridge columns and the need of performance on the basis of anti-seismic design in bridge,RC bridge column performance levels,i.e.full operation,temporary operation,reparable operation,life safety,and collapse prevention were established.Combined with research achievement at home and abroad,quantitative decision indexes of bridge structure failure were established from point of view of socio-economics.Based on field investigations following a seismic event,quantitative indexes of performance levels for field seismic disaster investigation of RC bridge column were proposed.Based on the statistical data of 127 seismic performance tests of RC bridge columns with circular section subjected to flexural failure,regarded drift ratio as performance parameters,quantitative indexes for the five designated performance levels were put forward.The indexes were compared with the provisions among New Zealand standard,Japan design code,and California design code.The results show that the drift ratios of RC bridge column with different performance levels are reasonable which can be used to determine displacement of column top on the basis of anti-seismic design.
News, Nations, and Power Relations: How Neoliberal Media Reproduce a Hierarchical World Order

This article adopts a poststructural approach to examine the relationship between the news media and international relations. It compares 15 years of international aid coverage from two donor nations, the United States and Britain, and two recipient nations, India and Pakistan, to understand the types of identities news media construct for a nation in relation to other nations. Despite their differences, the news discourse in all four nations has a neoliberal orientation. Moreover, neoliberalism underpins a hierarchical structure of relations that privileges some nations as superior and makes other nations willing participants in their own subordination. While scholars of press–state relations regard newsmaking as epiphenomenal to foreign policymaking, this article argues that newsmaking and policymaking are mutually constitutive social phenomena: both draw from and, in turn, reproduce a shared conception of national identity vis-à-vis other nations. In doing so, the article illustrates the productive power of news media in international relations.
