Solution-processed, ultrasensitive, high current density vertical phototransistor using porous carbon nanotube electrode

Multi-wall carbon nanotube (MWCNT) thin film has been identified as the ideal electrode material due to their inherent electronic and optoelectronic properties. We have successfully fabricated a vertical field-effect phototransistor (vFEpT) using MWCNT as a porous source electrode. The optimized MWCNT electrodes showed an electrical conductivity of 3.92 × 103 S/m and a sheet resistance of about 490 Ω/□, with a layer thickness of about 520 nm. The as-fabricated transistor has p-type conductivity because of the unintentional doping of the PbS layer and the intrinsic hole transport property of the MWCNT network. Additionally, the device shows excellent photoelectric performance at 30 mWcm−2 of illumination, with a high current density of 2.3 × 10−3 Acm−2. With a high conductivity network for carrier transfer and separation, the special characteristics of MWCNT nanoporous thin film enable improved photoelectric properties, such as a high photoresponsivity of 3.16 AW−1 and a specific detectivity of 2.33 × 1012 Jones when illuminated at 808 nm light irradiance with an intensity of 0.6 µW/cm2. Furthermore, the device demonstrated a steady dynamic response to an optical signal, with rising and falling times of 31.8 ms and 32.9 ms, respectively. This work presents a new method for creating high-performance vertical phototransistors with MWCNT as the source electrode.

Analyzing e-government agencies’ Twitter/X engagement: A case study of Nevada

This research aims to investigate the dynamics of interactivity between Nevada’s e-government and its citizens through the utilization of social media, with a specific focus on Twitter. Employing a mixed-methods approach, the study analyzed how Nevada state agencies engage with the public on Twitter, while concurrently assessing citizens’ responses through qualitative empirical research. These responses were categorized into content features, encompassing subjective opinions and sentiments (positive/negative), and structural features, comprising objective elements like special characteristics and multimedia components. Content analysis was employed to explore these features, leading to the identification of seven themes within a hypothesized two-dimensional framework, encompassing both the reflection of interactivity and the transmission of interactivity.<br /> Quantitative methods, specifically ANOVA and multiple regression analysis, were utilized to test the hypothesis. The findings revealed that Nevada e-government agencies predominantly used Twitter for one-way information dissemination, with limited two-way communication with citizens. To enhance interactivity, it is suggested that e-government posts incorporate multimedia elements and external links to facilitate information dissemination. Public administrators in the State of Nevada should focus on providing valuable and beneficial government posts, encouraging citizens to respond and express their opinions. Continuous training for public administrators is recommended, given the rapid advancements in technology and social media platforms.<br /> Furthermore, adopting best practices from domestic and international social media companies is advised to stay innovative. Public administration should transition from merely governing individuals and information to becoming facilitators and moderators of discourse on social media platforms. State e-government can strengthen citizen interaction by consistently delivering valuable information on social media, thereby obtaining immediate feedback, and influencing public opinion.

Experimental study on the influence of surface properties on droplet collision dynamics, from adhesion to rebound to breakup

Liquid droplet impact on dry surfaces often results in bouncing or breakup beyond a certain threshold. Surface contact angles, especially dynamic ones present during impact, significantly affect this process. Our experimental study underscores that advancing and receding contact angles influence droplet behaviors like rebounding and different types of breakup. This discovery provides new insights and criteria for understanding liquid droplet impact on surfaces. Special characteristics were found in the breakup on microstructured surfaces: the size of fractured droplets notably decreases, and the spreading–breakup occurs more easily and earlier. Additionally, microstructured surfaces reduce contact time to some extent. Furthermore, the uniqueness of oblique impacts is mainly reflected in how they lower the threshold of the receding contact angle for rebound. Studying the correlations and differences in droplet rebound and breakup related to these surface characteristics will contribute to improving research on liquid–solid interactions and the design of hydrophobic surfaces, including microstructured surfaces.

Uncovering the Profile of Ubiquitination Motif in Catalytic Proteins using Sequence Contextual Features

Ubiquitin molecules modify their target protein by conjugating the amino group of lysine side chain, thereby regulating the activity and function of most intracellular proteins. However, within multiple lysine residues on a target protein, only particular residues can be modified by ubiquitin molecules. The occurrence of ubiquitination varies on different lysine residues. The ubiquitination of a lysine residue is ubiquitinated depends on the environment of amino acid sequences near the lysine residue; this sequence is called a motif. Although the interaction of motifs with ubiquitin molecules have been extensively studied, there have been no reports on the ubiquitination motifs. In the current study, 133878 ubiquitinated peptide data from 27762 proteins in 30 articles and the mUbiSiDa database in the past decade were collected and analyzed. A total of 208 motifs were found with a score above 6, covering most of the ubiquitination peptides. Of these, six motifs with higher scores and significant regularity were found to belong to zinc finger proteins and serine/threonine kinases, termed zinc finger and serine/threonine kinase motifs, respectively. Analysis on four zinc finger motifs revealed that the ubiquitination sites in zinc finger motifs, xxHxxxxxxE_K_xxxCxxCxxx and xxxKxxHxxx_K_xxxxxExxKx, were located between two zinc finger domains, while the ubiquitination sites in zinc finger motifs, xxxxxxxxCG_K_xFxxxxxxxx and CxxxxxxFxQ_K_xxxxxxxxxx were located within zinc chelation structure near one Cys residue. Different proteins contain different types and quantities of zinc finger motifs. The results of the 3D structure showed that the ubiquitination sites in motif CxxxxxxFxQ_K_xxxxxxxxxx were located in the ring structure of the zinc finger domain. This may affect the interaction between zinc finger domains and DNA. Meanwhile, the ubiquitination sites of the other three zinc finger motifs located outside the interaction structure between zinc finger domains and DNA may not serve to block interaction but degradation. The analysis of two serine/threonine kinase motifs revealed that some residues near the ubiquitination site in two serine/threonine kinase motifs were completely identical in different proteins; however, these conserved residues were completely different in different motifs, suggesting the varied function of the two motifs. Moreover, it was found that no protein simultaneously contains both serine/threonine kinase motifs. Although there were significant differences in the amino acid sequences of these motifs, their spatial structures were highly conserved. These results suggest that the regulatory functions of the two motifs may differ. This is because two motifs may be recognized by different ubiquitinases or deubiquitinases. Overall, these results suggest that the motifs of ubiquitination sites exhibit high regularity and special structural characteristics in different types of proteins. This study sheds light on the profile and regularity of ubiquitination motifs, promoting the prediction of the function, structure, and modified sites of ubiquitinated proteins.

Nussbaum-Based Adaptive Neural Networks Tracking Control for Nonlinear PDE-ODE Systems Subject to Deception Attacks.

In this article, the novel adaptive neural networks (NNs) tracking control scheme is presented for nonlinear partial differential equation (PDE)-ordinary differential equation (ODE) coupled systems subject to deception attacks. Because of the special infinite-dimensional characteristics of PDE subsystem and the strong coupling of PDE-ODE systems, it is more difficult to achieve the tracking control for coupled systems than single ODE system under the circumstance of deception attacks, which result in the states and outputs of both PDE and ODE subsystems unavailable by injecting false information into sensors and actuators. For efficient design of the controllers to realize the tracking performance, a new coordinate transformation is developed under the backstepping method, and the PDE subsystem is transformed into a new form. In addition, the effect of the unknown control gains and the uncertain nonlinearities caused by attacks are alleviated by introducing the Nussbaum technology and NNs. The proposed tracking control scheme can guarantee that all signals in the coupled systems are bounded and the good tracking performance can be achieved, despite both sensors and actuators of the studied systems suffering from attacks. Finally, a simulation example is given to verify the effectiveness of the proposed control method.

Different Adaption Strategies of Abundant and Rare Microbial Communities in Sediment and Water of East Dongting Lake.

The dynamics of aquatic microbes is of great importance for comprehending the acclimatisation and evolution of microorganisms in lake ecology. However, little is known about the adaption strategies of microbial communities in East Dongting Lake, which had special and complexity geographical characteristics. A semi-enclosed lake area (A) and a waterway connected to Yangtze River (B) both existed in the lake zone. Here, we investigated bacterial and fungal community diversity, community network and community assembly processes in sediment and water. The results indicated that the proportion of OTU numbers and their relative abundance for rare and abundant taxa were different obviously between sediment and water, but not between bacteria and fungi. However, abundant subcommunities dominated the shifts of bacterial community diversity and structure in A region, while rare subcommunities for fungal community diversity. Compared to fungal community, bacterial network was more compact and more key stones were identified as rare taxa. In addition, stochastic processes (dispersal limitation) drove the community assembly of abundant and rare subcommunities, but the effects of deterministic processes (including variable and heterogeneous selections) affected more on rare rather than abundant taxa. Partial Mantel test further indicated that the effect of environmental factors was a stronger force in shaping abundant bacterial subcommunities (TOC, NH4+-N, TN, and ORP) and rare fungal subcommunities (ORP). Environmental factors explained more of the variation in bacterial community structure than that in fungal community structure, although they had additional effects on fungal community diversity and community assembly. Moreover, bacterial community affected the fungal community as a biotic factor in water. This research provided new insights into better understanding of microbial communities in the complex environment of the East Dongting Lake.

On the issue of the effectiveness of the civil law method in the regulation of health protection relations

The subject of the study is the rights of citizens to health protection, as well as the possibility of their transformation in the direction of strengthening the legal nature of these relations. In the context of the dominance of the sectoral approach in law, the author develops ideas about subjective law as an effective regulator of patient behavior. The opinion is expressed that the responsibility of the subject's independent choice can give a new impetus to improving the level of quality indicators of medical care, ensuring the timeliness, qualification and comprehensiveness of examinations. An attempt has been made to shift the focus in the process of streamlining relations from the subject of legal regulation to methods. New opportunities have been identified to increase the level of the legal nature of court decisions that can take into account the objective need to expand the scope of private law (civil) ways of influencing the patient on the medical process. The dialectical method has become the main research method. The conditions for improving medical care are revealed, taking into account the differences between public law and civil law regulatory methods in solving problems of law enforcement practice. The scientific novelty is that the examples of legal practice have provided new knowledge necessary for the development of existing doctrinal approaches in legal science. The limitations of the sectoral approach in law, due to the high degree of dynamism of society, are convincingly argued. It has been established that orientation to the subject of legal regulation, as an unconditionally dominant factor in choosing a strategy and tactics for streamlining relations, does not always ensure the completeness of the legal nature of judicial acts. The emphasis of legal regulation in health protection is focused on the priority use of public law (or "organizing") methods that guarantee the mass provision of medical care designed for everyone. The possibility of providing quality indicators of care to a specific patient with special health characteristics and conditions for receiving it is still secondary. It is necessary to actively apply civil law methods of protecting the right to health protection, while skillfully using the resource potential of the law.

Analysis of free amino acids and evaluation of the quality of gallnut honeys from different geographical areas

AbstractGallnut honey, a typical Chinese medicinal commodity, is produced from the nectar of Rhus chinensis Mill. Gallnut honey is very popular with consumers because of its health effects and nutritional value, but its specific nutritional composition and medicinal components are not clear. Free amino acids are important nutritional components of honey, and can provide relevant information about the honey, such as geographical and botanical origin, as well as adulterations. The aim of this paper was to explore the free amino acid characteristics of gallnut honeys in different areas. 18 free amino acids from 17 places in China were determined by automatic amino acid analyser analysis, and the geographical characteristics were studied by principal component analysis and cluster analysis. Results showed that gallnut honey is rich in free amino acids. A total of 12 types of free amino acids were detected in all honey-producing areas, and the total amino acid content was 0.132–0.292 g/100 g. Due to its free amino acid content gallnut honey has high nutritional supplement potential, and exhibits good pharmacodynamic activity and special taste characteristics. Flavour-related free amino acids were primarily aromatic free amino acids and umami free amino acids. Pharmacodynamic free amino acids accounted for 61.22–83.85%. Results also showed that free amino acids contribute to the geographical tracing of honey, and samples of gallnut honey at different altitudes can be distinguished by cluster analysis.

Enhanced erosion-corrosion resistance of monolithic ENP coating on ductile cast iron by using electrochemical pretreatment and heat treatment

This research aims to enhance the erosion-corrosion durability of monolithic ENP coating used on ductile cast iron. The ENP coating does not usually adhere well to the cast iron surface due to the special characteristics and innertness of the graphite sphere so an electrochemical surface pre-treatment containing a cathodic treatment was implemented to ensure proper adhesion of the coating to the surface. A slurry pot erosion-corrosion test was performed at a linear velocity of 10 m/s for 16 h, and it verified the efficacy of the treatment. Three different heat treatments were carried out on coated samples at 200 °C, 400 °C, and 600 °C. The sample heat-treated at 600 °C exhibited a pseudo-passivation behavior and displayed the best corrosion resistance of 0.1407 μA/cm2. Nonetheless, in erosion-corrosion tests, it was outperformed by other coatings due to the removal of its oxide layer. The heat treatment at 400 °C resulted in the highest hardness of 871 Vickeres and the best erosion-corrosion resistance of 8.8 mpy compared to 11.74 mpy for the as-plated sample and 381.3 mpy for the cast iron substrate.

부당 보전처분을 이유로 한 손해배상 - 대법원 2023. 6. 1. 선고 2020다242935 판결 -

If the creditor of a preservative measure loses the litigation on the merits, the creditor's intention or negligence in executing the preservative measure is presumed. This is the established position of our precedents. This precedents’ position is basically reasonable because preservative measures are made under the sole responsibility of the creditor based on an unilateral vindication by the creditor. Unless there is special evidence to the contrary, the creditor who loses the litigation on the merits is responsible for compensating the debtor for the damages suffered by the execution of the wrongful preservative measure. However, it is necessary to approve the rebuttal of presumption of the creditor’s intention or negligence more flexibly considering the concrete validity of each case. Especially when there are specific circumstances in which it is difficult to attribute the execution or maintenance of preservative measures solely to the creditor, it is not appropriate to place the responsibility entirely on the creditor. Examples include: Where legal assessment is difficult due to complex facts. Where the result of the litigation on the merits is overturned by a higher court due to such difficulties. Where it is difficult to determine whether it is due to a gap in facts or a gap in legal evaluation because the facts and the legal evaluation ore the interpretation of the law are closely intertwined. In the case of the the Supreme Court Decicion, the complex factual situations involving the amount of damages against the infringement of intellectual property rights led to divergent conclusions of the lower and higher court. The conclusions were different not because the facts that underlie the judgments were decisively changed, but because there were differences in legal evaluation or interpretation of the same facts. In these cases, it would be appropriate to consider that there is a substantial reason to rebut the presumption of the creditor's intention or negligence. There is a clear need to warn creditors to prevent wrongful preservative measures and to make creditors bear the damages from them. However, it is also undesirable to make the creditors hesitate to exercise their rights even when there is significant reason to believe that they are justified. As the creditor’s responsibility for wrongful preservative measures is imposed from the perspective of fairness, when and to what extent the responsibility should be imposed must be determined by fully considering the concrete facts and special characteristics of each case.

<남편 죽인 아내> 설화를 통해 본 제주 <메고할망> 설화와 본풀이 전승의 특수성 -여성의 ‘분노’와 ‘고통’에 대한 응시를 중심으로-

In The Wife Who Killed Her Husband folktale, the woman kills her current husband, who had previously murdered her first husband, as well as her children from her current marriage. In response to her actions, a memorial gate or pavilion is erected in her honor. In some variations of this tale, a son born from the current marriage kills his mother under the pretext of avenging his father’s death. Traditionally, this folktale has been interpreted through the concepts of “loyalty” and “revenge.” However, at the core of the narrative lies the misguided desire of a man to form a family by taking another man’s wife, alongside the anger of a woman whose life was ruined as a result. Recognizing and addressing the violence, victimization, and discrimination faced by women is a crucial part of forming a feminist subjectivity. When viewed through this lens, the son’s act of killing his mother can be interpreted as both a parody of and a backlash against the woman’s murder of her current husband. In contrast to The Wife Who Killed Her Husband folktale, where the woman’s report to the authorities leads to the erection of a memorial gate, the report made by Mego Halmang in the Jeju folktale leads to the punishment of her current husband and her own exoneration. The Jeju saying, “Even if you have ten (or nine) children, it’s all in vain,” which is often passed down along with the Mego Halmang folktale, reflects Mego Halmang’s feelings of shock and emptiness upon discovering that the husband with whom she has shared a long life and borne ten (or nine) children was, in fact, the murderer of her previous husband. In the folktale, after Mego Halmang kills her husband and children and dies in Bishini cave, the villagers who originally lived there leave and settle in Iseung cave, leaving Mego Halmang alone in the desolate Bishini cave. In the bonpuri, Mego Halmang, upon learning from the authorities that she is free to go wherever she wishes, descends to Iseung cave where the villagers live. People who experience suffering often feel an even greater need for someone to understand and acknowledge their pain. By continually revealing herself to the villagers living in Iseung cave and to the worshippers who visit Songssi Halmangdang, Mego Halmang gains recognition for her suffering. The gaze on women’s anger and pain is the special characteristic of the Jeju Mego Halmang folktale and its bonpuri within the overall landscape of the The Wife Who Killed Her Husband folktale.

Perancangan Sistem Keamanan Rumah Menggunakan Face Recognition (Pengenalan Wajah) Berbasis Raspberry Pi

Talking about technology, currently computer technology is developing very rapidly and is a field that has a very important role in several aspects of human life, including in the field of security. Currently, many home or room security systems have been developed with several identity verification methods using a computer system, using keys, cards, passwords, and so on. However, this method still has shortcomings such as humans' limitations in remembering number combinations which makes the door inaccessible. Therefore, techniques for reliable and accurate identification or verification can be designed using biometric technology that utilizes the special characteristics of the human individual.

Mixed-mode fracture assessment of largely deformable hyperelastic materials highlighting crack removal phenomenon

Due to the special mechanical characteristics, rubbers are nowadays utilized in various industries. In this research, the effect of an existing crack on the behavior of Nitrile Butadiene Rubber (NBR) filled with Carbon Black (CB), which has shown high deformability, is investigated experimentally, numerically and analytically under mixed-mode (I/II) loading. It is observed experimentally that in the cracked largely deformable rubbers, after the initial crack blunting, the crack is nearly removed and the specimen is deformed in such a way that almost no sign of stress concentration factor exists in the sample. Thus, the rupture of these rubbers is divided into two separate phases; named here as the crack removal phase and the final rupture phase, and for each separate phase, a distinct criterion is developed to assess the fracture of cracked rubbers. The good agreement between the theoretical predictions based on each criterion and the corresponding experimental data confirms the very good accuracy of the presented criteria. The independence of critical J-integral value (Jc) from the mode mixity is also investigated.

Improvements of the dynamics code TMSR3D for molten salt reactor leveraging triangular prism nodal method

Dynamic simulation with coupled model of neutronics/thermal-hydraulics (TH) is one of the crucial aspects in safety analysis for molten salt reactor (MSR), which requires a deeper insight into the interactions among hydrodynamics, heat transfer and neutron kinetics because of its special characteristics induced by fuel drift, in comparison to the traditional reactors using solid fuels. To improve the geometric adaptability and calculation precision of the MSR specific dynamics code TMSR3D based on quadrilateral nodal method and TH module including the multi-channel flow and single-channel heat transfer models, the analytic basis function expansion nodal (ABFEN) method using triangular prism nodes is implemented to solve the static neutron diffusion equations, an implicit backward difference method along with exponential transformation is adopted to deal with the neutron kinetics problems, and the concentration equations of delayed neutron precursors (DNP) considering fuel flow are solved by the method of characteristics. The VVER-440 transient benchmark is first selected to validate capacity of the updated code for simulating core with hexagonal assemblies. Subsequently, the Molten Salt Reactor Experiment (MSRE) is simulated for further validation, in which the steady-state characteristics including delayed neutron loss induced by circulating fuel, profiles of reactor temperature and DNP, impact of fuel residence time in external loop on the effective yields of delayed neutrons, two fuel pump driven transients, and the natural convection are analyzed and discussed in detail. The results agree well with that from similar codes and the experimental values, which indicate that the improvements conducted for TMSR3D are effective and correct.

Admission characteristics of patients with short term hospitalization

BackgroundSheba Medical Center (SMC) is the largest hospital in Israel and has been coping with a steady increase in total Emergency Department (ED) visits. Over 140,000 patients arrive at the SMC's ED every year. Of those, 19% are admitted to the medical wards. Some are very short hospitalizations (one night or less). This puts a heavy burden on the medical wards. We aimed to identify the characteristics of short hospitalizations.MethodsWe retrospectively retrieved data of consecutive adult patients admitted to our hospital during January 1, 2013, to December 31, 2019. We limited the cohort to patients who were admitted to the medical wards. We divided the study group into those with short, those with non-short hospitalization and those who were discharged from the ED.ResultsOut of 133,126 admissions, 59,994 (45.0%) were hospitalized for short term. Patients in the short hospitalization group were younger and had fewer comorbidities. The highest rate of short hospitalization was recorded during night shifts (58.4%) and the rate of short hospitalization was associated with the ED daily patient load (r = 0.35, p < 0.001). The likelihood of having a short hospitalization was most prominent in patients with suicide attempt (80.0% of those admitted for this complaint had a short hospitalization), followed by hypertension (68.6%). However, these complaints accounted for only 0.7% of the total number of short hospitalizations. Cardiac and neurological complaints however, made up 27.4% of the short hospitalizations. The 30-days mortality rate was 7.0% in the non-short hospitalization group, 4.3% in the short hospitalization group and 0.9% in those who were discharged from the ED.ConclusionsShort hospitalizations in medical wards have special characteristics that may render them predictable. Increasing the rate of treating personnel per patient during peak hours and referring subsets of patients with cardiac and neurological complaints to ED-associated short term observation units may decrease short admissions to medical departments.

PSXIII-16 Kinematics and viability of spermatozoa from Criollo and Angus bulls in a low-input system

Abstract The Chihuahuan Criollo cattle is a genetic resource with special adaptive characteristics to rough, arid and semi-arid ecosystems. There is a great interest in incorporating such adaptations into beef production systems as one of the strategies for sustainable production to face the climate change challenge. Reproductive success is determinant to achieve sustainability in animal production systems. Most research efforts to improve reproductive efficiency have focused on the study of females. However, it has been shown that much of the economic losses caused by embryonic deaths are due to the bull. The aim of this study was to evaluate the quality of thawed semen from Angus and Criollo bulls kept in a low-input system. Thirteen healthy bulls (n = 7 Angus and 6 = Chihuahuan Criollo), with an average age of 4.3 ± 0.48 yr, grazing in the same rangeland and subjected to natural pasture conditions, were studied. Semen obtained by electroejaculation, were frozen and subsequently thawed for analyses. Characteristics of motility, vitality (V), morphology (M) and plasma membrane integrity (PMI) were evaluated in fresh and thawed semen, whereas movement kinetics (MK) and acrosome reaction (AR) were evaluated in thawed semen. Statistical analysis was performed using the PROC GLM of SAS Studio 2022 including the fixed effects of breed, semen condition and their interaction for variables of progressive motility (PM), V, M, PMI and the effect of breed for variables of MK and AR. As expected, PM and V were less (P &amp;lt; 0.05) in thawed (57.93 ± 4.1 and 53.69 ± 2.7) compared with fresh (72.64 ± 3.9 and 74.98 ± 2.6) semen, whereas no differences (P &amp;gt; 0.05) were found in M. However, the interaction between semen condition and breed for PMI tended to the significance (P = 0.08) with a PMI of 68.95 ± 4.6 and 58.98 ± 4.3 for Criollo and Angus, respectively, in fresh semen, whereas in thawed semen this difference was inverted (52.08 ± 4.6 and 58.40 ± 4.6). It is important to note that the semen retained quality traits with values above the minimum accepted for use in artificial insemination, despite the scarcity of resources of the system in which the animals were kept. There were no differences by breed in the main MK variables; however, AR reported as live unreacted sperm was less (P &amp;lt; 0.05) in Criollo (40.49 ± 4.49) compared with Angus bulls (58.48 ± 4.49). In conclusion, it is important to incorporate the assessment of membrane integrity and acrosome reaction in thawed semen evaluation to obtain a more accurate prediction of the potential fertility of samples, even if motility parameters appear to be optimal.

Development of a novel circular saw blade substrate with high stiffness for mitigating vibration noise and improving sawing performance

The circular saw blade substrates featuring a large diameter-thickness ratio and multiple saw teeth are increasingly required to accomplish the first or second machining tasks with high efficiency in sawing operations. However, the weak bending stiffness of this substrate can easily cause intense vibrations and harsh noises, while its special structure characteristics pose further challenges to vibration mitigation. This research develops a novel circular saw blade substrate with high bending stiffness to improve dynamic stability. Taking the geometric features and boundary conditions of the substrate into account, a transverse vibration differential equation for high-speed sawing operation is established to investigate the relationship between the mode shapes of the substrate and the stability performance of the sawing system. Theoretical analysis shows that the laminated structure can enhance the bending stiffness. Using this finding, the novel substrate is designed equipped with an m-shaped damping cavity and a laminated core structure, and its dynamic performance is quantified by the complex modulus law and thin-plate vibration theory. Then, the optimized design of the relevant materials and geometrical dimensions of the novel substrate is executed by the pseudo-density method. Finally, the novel substrate is fabricated and then certified by sawtooth point dynamics tests and sawing experiments. The experimental results show that the sawing quality of the novel substrate is improved by more than 50.2 %, and the sawing vibration and weighted sound pressure level are reduced by about 35 % and 12 dB(A), respectively, compared with the conventional one.

Convergence analysis of iteratively regularized Landweber iteration with uniformly convex constraints in Banach spaces

In Banach spaces, the convergence analysis of iteratively regularized Landweber iteration (IRLI) is recently studied via conditional stability estimates. But the formulation of IRLI does not include general non-smooth convex penalty functionals, which is essential to capture special characteristics of the sought solution. In this paper, we formulate a generalized form of IRLI so that its formulation includes general non-smooth uniformly convex penalty functionals. We study the convergence analysis and derive the convergence rates of the generalized method solely via conditional stability estimates in Banach spaces for both the perturbed and unperturbed data. We also discuss few examples of inverse problems on which our method is applicable.
