Operation Scheduling of Distribution Network with Photovoltaic/Wind/Battery Multi‐Microgrids and Reconfiguration considering Reliability and Self‐Healing
Authors: Kalantari Alireza , Lesani Hamid
Published: May 2024

In this paper, a new simultaneous framework of distribution network operation is proposed based on the scheduling of photovoltaic/wind/battery multi‐microgrids with network reconfiguration considering self‐healing. The objective function is considered to minimize the energy losses, and multi‐microgrids cost and improve the reliability indices including minimization of energy not‐supplied (ENS) and minimizing system average interruption duration (SAIDI) and system average interruption frequency (SAIFI) indices. The optimization variables are defined as the situation of the distribution network switches to find the network’s optimal configuration with the installation location and size of renewable resources and battery energy storage during 24 hours. An improved beluga whale optimization (IBWO) based on a nonlinearly diminishing inertia weight (NDIW) approach is used to find the optimal variable set of the problem. The recommended methodology is implemented on 33‐bus and real 59‐bus distribution networks. The results demonstrated that by obtaining an optimal state of the network switches in the event of a fault, as well as the optimal scheduling of the two microgrids, the energy losses have decreased and the reliability indices have improved. The outcomes of the proposed methodology based on the hybrid multi‐microgrid allocation and network reconfiguration are stated that the losses, ENS, SAIDI, and SAIFI are reduced by 66.39%, 54.00%, 50.24%, and 33.61%, respectively, for 33‐bus network and are declined by 65.29%, 57.44%, 48.63%, and 62.33%, respectively, for the real 59‐bus Ahvaz network in comparison with the base network. The obtained results illustrated that in the condition of the network line outage, by simultaneously implementing the reconfiguration with the change of network switches and the optimal allocation and scheduling of HMGs in the network, self‐healing is provided to prevent a significant weakening of the network performance so that the resilience is improved in addition to minimizing the energy losses and the cost of HMG energy injection compared to the base network. The findings revealed that the objectives including losses, ENS, SAIFI, and SAIDI are increased by 78.29%, 33.00%, 83.33%, and 35.11%, respectively, due to outage of line 22 of the 33‐bus network and these objectives are increased by 52.32%, 10.30%, 32.29%, and 79.66%, respectively, due to outage of line 12 of the 59‐bus network compared with not considering the line outage. Moreover, the superior capability of the recommended NDIW‐based IBWO has been confirmed in comparison with the well‐known particle swarm optimizer (PSO) and ant lion optimizer (ALO) in solving the problem to achieve better objective value.

Pharmaceutical excipients are classified based on the function(s) in the processing and/or finished product. However, functionality evaluations, procedures, and related acceptance criteria for excipients tend to depend on the dosage form, and assessment is usually done on a case-by-case basis. This means that any useful and reliable evaluation of the overall functionality-related properties is only possible within the context of the specific formulation method. This study evaluated the physicochemical, functional, and related properties of purified gum obtained from the stem bark of the Cussonia arborea tree. The purified gum was acidic (pH 5.32–5.50) with percentage (%) moisture content and insoluble matter of 13.33 ± 0.33 and 0.47 ± 0.01, respectively. Moreover, it was soluble in all the aqueous-based solvents but insoluble in all the organic solvents. The total ash of the gum was higher than that of international standard gum Arabic. Micromeritic properties indicated the need for a flow aid to improve flowability. Six formulated batches of tablets containing 0.5–5%w/w of gum, respectively, were generally soft with none passing the USP T80 standard of drug dissolution indicating poor tablet binding and drug-releasing properties. The disintegration action of CAPG was poor (only batches containing 0.5 and 1% CAPG passed) and was not comparable to that of the standard corn starch. The gum was therefore considered a poor disintegrant and binder in the formulation of conventional release tablets.
Looking Back and Moving Forward: Historical Lessons for Current Research on Moral Development
Authors: Turiel Elliot
Published: May 2024

A history of research on the development of morality yields valuable lessons. In 1932, Piaget examined children’s moral judgments, proposing that actions feedback on judgments, which in turn feedback on actions. He analyzed children’s entry into the moral realm through a sense of obligation. Subsequently, Kohlberg proposed a sequence entailing differentiations of justice from non-moral considerations, emphasizing epistemology, and how one level of development is more adequate than prior levels. The Piaget and Kohlberg differentiation models of development have not held up to subsequent evidence; young children distinguish morality from social conventions as well as from the domain of personal jurisdiction. History points to issues requiring further analyses. These include expositions of children’s entry into the moral domain; developmental transformations and the bases for greater adequacy; interrelations between judgments and actions; and connections between judgments and emotions, including study of on-going, background dispositions labeled sentiments.

Published: May 2024

The present research shows the absurdity of education, especially education management, in the posthumanist schema. Posthumanists seem to want to form their own group, but researchers see that posthumanism is not new, especially in the world of education. Philosopher Mortimer J. Adler, in the framework of perennialism, shows the structure of education, especially in America, which, according to researchers, is relevant in Indonesia. Research findings are based on qualitative research with data retrieval methods from literature studies. Results showed that Mortimer J. Adler's philosophical thinking emphasizes the expansion of education management in both depth and fragility by and through learners, parents, teachers and related parties in the mecca of an independent curriculum.

Published: May 2024

This qualitative case study aimed to explore fillers usage to address speaking challenges related to the improvement of self-confidence and motivation in speaking practices done by two English foreign language (EFL) learners of the English department of one of the Islamic Universities in Malang, Indonesia. Data were collected through observations and in-depth interviews to two students employing filler strategies to address speaking challenges related to the improvement of self-confidence and motivation during their speaking exercises. The research revealed that both learners used fillers to address speaking challenges during the conversation due to their linguistic components’ shortage such as a limited mastery of vocabularies and having a little understanding on grammar. Fillers might bring them to have more self-confidence in speaking practices shown by not being afraid of making mistakes when they practice speaking with their speaking partners. Fillers might bring them to have more motivation in speaking shown by their enthusiasm to get involved in the discussion whether in group or class discussions. Thus, fillers usage is prominent due to its potential to address speaking challenges, enhance self-confidence and motivation, eventually contributing to an overall improvement in language proficiency particularly in speaking skill.

Published: May 2024

Recently, the readability of texts has become the focus of reading research because it is believed to have implications for reading comprehension, which is of utmost importance in the field of English as a foreign language (EFL), particularly in the teaching, learning and assessment of reading comprehension. Unfortunately, the influence of text readability on reading comprehension (and reading time) has not been well studied in the EFL context. Most text readability studies are conducted in medical contexts, but these studies are often limited in predicting readability scores for sample texts. To address this gap, the current study aimed to evaluate the influence of text readability levels (based on the Flesch-Kincaid grade level (FKGL)) on students’ reading comprehension and reading time. Data were collected through reading test and analyzed using SPSS version 22. The Friedman test revealed that the distribution of students' reading comprehension score (X2=197.532, p=0.000) and reading time (X2=215.323, p=0.000) are different in each text, suggesting that the readability of texts has a significant influence on both. This study contributed to the practices of reading instruction and assessment. Limitations and suggestions for further research are briefly discussed.

This study's focus is to determine refugee teachers' views regarding their ability to work as teachers in Germany, their initiatives, and the challenges they face. In this context, the study was conducted based on qualitative research methodology. In order to collect data a total of 265 teachers residing in the 16 states of Germany were reached. Upon examining the results, it is observed that the majority of participants express a desire to work as teachers in Germany, while only a few have actually obtained the opportunity to work as teachers in Germany. More than half of the participants who are currently working as teachers reside in the North Rhine-Westphalia state. When analyzing the results, it becomes evident that a significant portion of the participants are strongly inclined to pursue a teaching career in Germany. However, the data reveals that the actual attainment of employment as teacher in Germany remains relatively low among the respondents. Furthermore, it is noteworthy that a majority of the teachers currently employed in the profession are concentrated in the North Rhine-Westphalia state.

Published: May 2024

On 1 October 2004, a new Royal Netherlands Embassy building opened in Warsaw, Poland. Its striking, contemporary appearance surprises and seduces at the same time: glass, concrete and wood artfully intersect in a sophisticated design that champions transparency and openness. This four-year building project commissioned by the Dutch Ministry of Foreign Affairs was entrusted to the highly acclaimed Dutch architect Erick van Egeraat (b. 1956). His carefully conceived architectural programme invites a wider discussion on the ways in which embassy architecture can support the aspirations of modern diplomacy. To this end, this article situates the Dutch Embassy building within the wider context of Dutch–Polish diplo-matic relations and examines how its design contributes to defining the practice of Dutch diplomacy. It also proposes a comparative view of trends within Dutch embassy architecture by considering other contemporary ex-amples in South America, Central Europe and Africa.
Warring Emotions: Anger, Settler Colonialism and Racecraft in Sixteenth-Century Florida
Authors: Martel Heather
Published: May 2024

This is an emotional history of an emotional alliance of French and Indigenous warriors who united to avenge the Spanish massacre of the Huguenot Fort Caroline in Florida in 1565. In this alliance, Indigenous fury was normalised when it served French Protestant interests. However, Protestant representations of Spanish and Indigenous rage used for the black legend presently came to found racist arguments for structural violence in settler colonialism and American white supremacy that are gendered and rooted in bodies. To explain, this essay sets this revenge story within the logics of the sixteenth-century French emotional regime.
Learned 1D Passive Scalar Advection to Accelerate Chemical Transport Modeling: A Case Study with GEOS-FP Horizontal Wind Fields
Authors: Park Manho , Zheng Zhonghua , Riemer Nicole , Tessum Christopher W.
Published: May 2024

We developed and applied a machine-learned discretization for one-dimensional (1D) horizontal passive scalar advection, which is an operator component common to all chemical transport models (CTMs). Our learned advection scheme resembles a second-order accurate, three-stencil numerical solver but differs from a traditional solver in that coefficients for each equation term are output by a neural network rather than being theoretically derived constants. We subsampled higher-resolution simulation results—resulting in up to 16× larger grid size and 64× larger time step—and trained our neural-network-based scheme to match the subsampled integration data. In this way, we created an operator that has low resolution (in time or space) but can reproduce the behavior of a high-resolution traditional solver. Our model shows high fidelity in reproducing its training dataset (a single 10-day 1D simulation) and is similarly accurate in simulations with unseen initial conditions, wind fields, and grid spacing. In many cases, our learned solver is more accurate than a low-resolution version of the reference solver, but the low-resolution reference solver achieves greater computational speedup (500× acceleration) over the high-resolution simulation than the learned solver is able to (18× acceleration). Surprisingly, our learned 1D scheme—when combined with a splitting technique—can be used to predict 2D advection and is in some cases more stable and accurate than the low-resolution reference solver in 2D. Overall, our results suggest that learned advection operators may offer a higher-accuracy method for accelerating CTM simulations as compared to simply running a traditional integrator at low resolution.

Significance Statement

Chemical transport modeling (CTM) is an essential tool for studying air pollution. CTM simulations take a long computing time. Modeling pollutant transport (advection) is the second most computationally intensive part of the model. Decreasing the resolution not only reduces the advection computing time but also decreases accuracy. We employed machine learning to reduce the resolution of advection while keeping the accuracy. We verified the robustness of our solver with several generalization testing scenarios. In our 2D simulation, our solver showed up to 100 times faster simulation with fair accuracy. Integrating our approach to existing CTMs will allow broadened participation in the study of air pollution and related solutions.

Convective clouds play an important role in Earth’s climate system and are a known source of extreme weather. Gaps in our understanding of convective vertical motions, microphysics, and precipitation across a full range of aerosol and meteorological regimes continue to limit our ability to predict the occurrence and intensity of these cloud systems. To improve predictability, the National Science Foundation (NSF) sponsored a large field experiment entitled “Experiment of Sea Breeze Convection, Aerosols, Precipitation, and Environment (ESCAPE).” ESCAPE took place between 30 May and 30 September 2022 in the vicinity of Houston, Texas, because this area frequently experiences isolated deep convection that interacts with the region’s mesoscale circulations and its range of aerosol conditions. ESCAPE focused on collecting observations of isolated deep convection through innovative sampling and developing novel analysis techniques. This included the deployment of two research aircraft, the National Research Council of Canada Convair-580 and the Stratton Park Engineering Company Learjet, which combined conducted 24 research flights from 30 May to 17 June. On the ground, three mobile X-band radars and one mobile Doppler lidar truck equipped with soundings were deployed from 30 May to 28 June. From 1 August to 30 September 2022, a dual-polarization C-band radar was deployed and operated using a novel, multisensor agile adaptive sampling strategy to track the entire life cycle of isolated convective clouds. Analysis of the ESCAPE observations has already yielded preliminary findings on how aerosols and environmental conditions impact the convective life cycle.
The Innate Capacity for Representing Subjective Experience: The Infant’s Mind is Neither Primitive nor Prerepresentational
Authors: Erreich Anne
Published: May 2024

The author cites the prominence of theories that locate serious adult psychopathology in the preverbal infant’s inability to formulate or represent traumatic experience. The work of two such authors, H. Levine and D. B. Stern, is briefly considered. The frame of reference for this investigation is that clinical and academic research findings are highly relevant to psychoanalytic theorizing. It is argued that when such findings are considered, a view of the infant with “primordial and unrepresented” states of mind has little evidence to support it. In fact, research findings summarized herein point to an opposite view: that of the “competent infant,” one with highly accurate perceptual discrimination capacities and an innate ability to register and represent subjective experience in both procedural and declarative memory, even prenatally. Given the infant’s competencies, it seems implausible to hold that representational deficits are at the heart of serious adult psychopathology, which is instead seen to be the result of defensive maneuvers against unknowable and unspeakable truth rather than the absence of a preverbal representational capacity. Current research findings seem to pose a significant challenge for psychoanalytic theories that espouse “primitive mental states”; “unrepresented,” “unformulated,” or “unsymbolized” experience; or “nonconscious” states.

This study explores the link between a history of breast cancer and the vulnerability to heart failure. Analyzing data from the National Inpatient Sample (NIS) for women diagnosed with breast cancer between 2016 and 2019 in the US, our research utilized logistic regression, adjusting for demographics, comorbidities, and lifestyle factors, and employed propensity score matching. With 2,276,639 weighted cases, our findings reveal a slight but significant elevation in heart failure risk among the breast cancer cohort, specifically in acute, chronic, and isolated systolic heart failure types. Racial differences were pronounced; Black women with breast cancer showed higher risks for all heart failure types, particularly chronic and systolic, while Asian or Pacific Islander patients had a lower incidence of certain heart failure types. This research underscores a modest increase in heart failure risk post-breast cancer, highlighting the critical need for integrated cardio-oncology care and personalized healthcare approaches to address and mitigate this risk effectively.
China’s Ukraine Policy: Unchanged Rhetoric Despite Changing Conjuncture
Authors: Alperen Ümit
Published: May 2024

This article discusses China’s approach to the Ukraine crisis and the factors that shape China’s attitude to this situation in the comparative timelines of the 2014 and 2022 crises. Despite the changes in China’s security perceptions and the balance of power in the international system, China’s rhetoric about the ongoing Ukraine crisis has vague rhetoric similar to the crisis in 2014. While China regards the 2014 Ukraine crisis as a regional crisis, it sees the recent situation as a crisis with global effects. China’s approach to the Ukraine crisis, which is on its way to becoming a global power, is shaped within the framework of multiple contradictory parameters. First, at the discursive level, the ‘five principles of peaceful coexistence’ have formed the discursive framework of Chinese foreign policy since the 1950s. Second, the rapidly developing China–Russia relations after the Cold War, and third, the increasing threat China perceives from the United States, which it sees as a global hegemonic power, and in this context, its global policies. As a result, it is possible to define China’s approach to the Ukraine crisis as passively pro-Russian.

Published: May 2024

Foreign bodies (FBs) in the digestive tract are common in children, we analyzed the clinical characteristics of children with FBs in the digestive tract and discuss the risk factors for serious complications. We retrospectively reviewed clinical data of 139 children with FBs in the digestive tract. Based on the severity of complications caused by FBs, the patients were divided into risk and general groups for analysis and comparison. Significant differences were observed in the retention sites of FBs, the diameter of FBs retained in the esophagus, FBs retention time exceeding 24 h, and the absence of witnesses between the 2 groups. Inadequate care, button batteries (BBs), ingested mmFBs, FBs retained in the esophagus, long-term retention, and giant gastric bezoars may cause serious complications. In addition to treating FBs and the complications, clinicians should emphasize the importance of childcare to prevent the ingestion of FBs.
Responding to Covid-19 Pandemic: Policy and Governance Perspective to Reverse Migration in Uttarakhand
Authors: Kandpal Prakash Chand
Published: May 2024

The coronavirus disease, commonly referred to as Covid-19, had engendered inadvertent and significant societal upheaval, widespread economic setbacks, and compelled the relocation of individuals on a global scale. Analogous repercussions have been witnessed in the context of India, notably exemplified by the mass exodus of migrant labourers from their designated areas of employment to their native regions, precipitated by a comprehensive governmental lockdown enacted to interrupt the transmission chain of Covid-19. This stringent lockdown exacerbated the plight of economically marginalised migrant workers, compelling them to endure financial precarity and minimal reserves while confined to their residences. Consequently, a substantial number of migrants, primarily employed in the informal sector, found themselves compelled to return to their ‘places of origin’ from their ‘places of destination’ as an imperative means of survival. The present article elucidates the characteristics and ramifications of this phenomenon of reverse migration, undertaking an evaluative analysis of India’s response to the challenges posed by reverse migration in the aftermath of the Covid-19 pandemic. Special attention is directed towards the policy and governance dynamics, with a particular focus on the hilly state of Uttarakhand, India.
A high-altitude geomagnetic matching area selection approach based on geomagnetic information entropy and geomagnetic direction entropy
Authors: Han Yongqiang , Liang Ruirui
Published: May 2024

Aiming at the obvious trend of the contours on the high-altitude geomagnetic map, this paper presents a method of high-altitude geomagnetic matching area selection combining geomagnetic information entropy and geomagnetic direction entropy based on the study of geomagnetic information entropy and geomagnetic direction entropy. The method first uses geomagnetic information entropy to select the region with rich geomagnetic information, and then determines the direction of the flight trajectory according to geomagnetic direction entropy to obtain the optimal matching trajectory. Finally, the method compares and analyzes the matching localization results of three flight trajectories in different directions on the geomagnetic map at an altitude of 30,000 m by using semi-physical simulation. The experimental results show that the flight navigation error along the trajectory with small information entropy is small, and its positioning error is 12.7% of the trajectory positioning error along the maximum information entropy direction. Selecting the flight trajectory according to the value of the geomagnetic direction entropy can greatly improve the precision and reliability of the geomagnetic matching localization. The method in this paper can provide a basis for path planning of the geomagnetic matching navigation.

Published: May 2024

This study assessed the effectiveness of modified schema-based instruction (MSBI) in teaching students with autism spectrum disorder (ASD) how to solve additive compare word problems. The study was conducted in Spain, and it involved three students with ASD who were 6, 7, and 9 years of age. A single-case, multiple-baseline across-students design was followed. Results indicated a functional relation between MSBI and improved performance in solving additive compare problems of type difference amount unknown and compare amount unknown, maintained for 4 to 6 weeks post-intervention. Additionally, two students successfully applied their skills to reference-amount-unknown compare problems, demonstrating successful generalization. However, their generalization to problems involving two operations was somewhat limited by difficulties with one of the operations. Social validity data collected from the students’ families and teachers indicated that both groups had positive views on the use of the MSBI for mathematical word problem-solving skills.

Published: May 2024

Hydrostatic pressure resistance serves as a crucial metric in the assessment of water resistance in woven fabrics. The expeditious, precise, and efficient conduct of hydrostatic pressure tests holds paramount importance in advancing the progress and production of high-performance textiles. Addressing the challenges posed by intricate printed patterns on woven fabrics, and the presence of small, widely scattered water droplets, the study leverages the enhanced YOLOv8 model to develop a machine vision-based automated detection technique for assessing water resistance in woven fabric. The proposed method incorporates convolutional block attention module attention mechanisms into the backbone and neck network, replaces the path aggregation network structure of YOLOv8 with the bidirectional feature pyramid network structure, and introduces a dedicated detection head for small targets. These enhancements facilitate accurate identification of water outlet points on the woven fabric and precise recording of frame positions, enabling the precise measurement of hydrostatic pressure. Validation of the proposed model is conducted through a series of comparative experiments utilizing a self-collected dataset. The experimental results underscore the exemplary performance of the proposed model, evidenced by an AP0.5 score of 92.18%, showcasing superior overall efficacy in comparison with alternative models. Notably, the target localization time error is found to be less than 2 s when contrasted with manual detection. This method substantially enhances the accuracy of water droplet detection and localization in hydrostatic pressure resistance testing of woven fabric, characterized by complex surface patterns, thereby contributing to refinement of hydrostatic pressure testing methodologies in woven fabric analysis.

This study aimed to assess the current status of gestational diabetes mellitus (GDM) diagnosis and management, and the demand for a digital healthcare system, in order to develop an optimal digital-based management model for GDM. An anonymous online survey was conducted targeting pregnant/postpartum women (Group W), internal medicine physicians (Group P), and obstetricians (group O) from September 6, 2022 to December 31, 2022. The survey assessed the women’s knowledge of GDM and gathered information about healthcare professionals’ (HCPs) current GDM management practices. All groups were asked about their acceptance of and demands for a digital healthcare system for GDM. Statistical comparisons between groups were conducted using the chi-square test or Fisher’s exact test where appropriate. A total of 168 participants were in Group W, 185 in Group P, and 256 in Group O. Participants from all groups recognized the need for a digital healthcare system for GDM (Group W: 95.8%, Group P: 85.9%, Group O: 60%). However, HCPs showed less willingness to integrate these systems into their clinics than pregnant/postpartum women. Essential features identified were recording blood glucose levels and insulin, along with automatic data linkage from self-monitoring devices. Group W showed a higher preference for lab test access, search functionality, and fetal weight assessment than groups P and O (all P < .0001), while Groups P and O had a greater preference for recording insulin and maternal body weight compared to Group W ( P = .0141 and .0023, respectively). Both pregnant/postpartum women and HCPs acknowledged the benefits of utilizing a digital healthcare system for managing GDM. However, there were differences in perspectives among these groups.
Recruitment Barriers and Potential Strategies for Inclusion of Older Asian Americans in Alzheimer's Disease Research

Published: May 2024

The makeup of the US population of older adults continues to become more diverse as numbers from ethnic subgroups increase. However, these subgroups are generally underrepresented in research focused on Alzheimer's disease and related dementias (ADRD). This paper examines barriers to recruitment for older Asian Americans, to underpin potential strategies for future research, with particular emphasis on recruitment of Vietnamese Americans. The paper discusses three recommended strategies: implementing appropriate recruitment outreach methods, establishing and maintaining community partnerships, and adopting flexible and convenient assessment methods. All three complementary approaches may be applied to improve Vietnamese American aging research participation. This has the potential to promote early intervention, foster longevity, ameliorate health disparities, and reduce healthcare burdens for this population.
Beyond Code of the Street and Psychopathic Features: Black Masculinity and Self-Compassion
Authors: Morley Richard H. , Taylor Matthew J. , Mason Michael
Published: May 2024

The role of self-compassion in relation to code of the street, psychopathic features, and masculinity was examined among a sample of 207 African American men. Participants were recruited online through the MTurk website. Using correlational and Preacher and Hayes (2008) bootstrapping analyses, results showed that masculinity was positively correlated with code of the street but not self-compassion or psychopathy. The correlational analyses also revealed that self-compassion displayed a negative correlation with code of the street and psychopathy. Code of the street and psychopathy were also found to be positively associated. The mediational analysis demonstrated that self-compassion mediated the relationship between the code of the street and psychopathy. The potential utilization of self-compassion as a transforming concept is discussed.
Whose Streets? Our Streets! . . . or Maybe Not? Legitimizing Racialized Gendered Policing in Modern Cities
Authors: Williams Rhonda Y.
Published: May 2024

“Whose streets? Our streets!” This special forum centered on The Streets Belong to Us: Sex, Race, and Police Power from Segregation to Gentrification conjures this popular urban protest chant that may (or may not) be familiar to many readers. While the response—“our streets!”—is forceful, it is far from a clear-cut truism or uncomplicated declaration. Herein, Fischer and five interlocutors discuss the historical and spatial complexities regarding who has a right to define, navigate, and regulate urban spaces. They take up the questions—to whom do the streets belong—by considering regimes of police power at the nexus of sex, moral reform, and so-called “troublesome” terrains in three twentieth-century U.S. cities. They also engage how, as Fischer states, law-enforcement practices of sexual policing decriminalized white womanhood while criminalizing Black womanhood, and thereby expanded police authority, racialized gendered state violence, carceral feminism, gentrification, and spatialized racial and economic inequalities.
Adaptive path tracking control for autonomous vehicles with sideslip effects and unknown input delays
Authors: Zhou Xin , Wang Heng , Li Qing , Wu Libing
Published: May 2024

This paper presents an adaptive path-tracking control of autonomous ground vehicles with sideslip effects and time-varying input delays. To handle the problem of unknown time-varying input delays, the vehicle kinematic model is transformed into a novel chain model, and a delay-based auxiliary integral term is introduced for the estimation of the unknown terms caused by time-varying delays. To avoid modeling errors caused by existing linear approximation methods, a new adaptive path-tracking control strategy is proposed, such that the optimal tracking performance is achieved by appropriately adjusting certain design parameters. In addition, the inherent complexity explosion issue is avoided with the aid of a boundary estimation strategy. All signals of the closed-loop systems are guaranteed to be bounded. Simulation results illustrate the effectiveness of the method proposed.
Endoscopic Management of Recurrent Epistaxis Caused by Retiform Hemangioendothelioma in a Child: A Case Report
Authors: Xu Baicheng , Tan Huan , Bian Panpan
Published: May 2024

Retiform hemangioendothelioma (RH) is a rare intermediate (locally aggressive) vascular tumor that mostly affects the dermis of the trunk and limbs, but has never been reported in the inferior turbinate. A 10-year-old Chinese boy presented with recurrent epistaxis in his left nasal cavity and anemia for more than 2 years. Radiographic and electronic video laryngoscopic images showed an expansile mass in the left inferior turbinate. Endoscopic surgery and electrocautery were performed to resect the tumor beyond the macroscopic border. Histopathologically, the tissues were infiltrated by hyperplastic blood vessels arranged in a retiform pattern, and endothelial cells proliferate significantly in some areas. Immunohistochemistry showed a positive result for CD31, CD34, Fli-1, and ERG. No epistaxis, tumor recurrence, or metastasis was found on reexamination over 18 months after surgery.
A Regional Analysis of the Impacts of Changes in Housing Values on Property Tax Assessment During and After the 2008 Financial Crisis
Authors: Deng Yunni , Skidmore Mark
Published: May 2024

This study examines the relationship between changing house prices and assessed value in the Detroit Michigan region. Using parcel-level data from 2008 through 2016, we construct a Hedonic Housing Price Index and an Assessed Value Index for 120 Michigan assessing jurisdictions in the five-county region surrounding Detroit (Macomb, Monroe, Oakland, Washtenaw, and Wayne). Our findings are consistent with the literature, indicating at least a three-year lag between changes in house prices and changes in property assessments. Communities considered to be distressed tended to over-assess properties before the crisis, but these communities recalibrated assessments to better align with market conditions after the financial crisis. Our evaluation also shows that while assessed values decreased more slowly than housing prices fell during the crisis, assessed values tended to fall to even deeper levels than housing prices over a longer time horizon.
