Authors: Lin Yibin , Sutunyarak Chonlavit
Published: May 2024

This study focuses on the problems of imperfect internal control effectiveness, insufficient information transparency, and plummeting stock prices. The study selects the data of non-financial main board listed companies in China’s Shanghai and Shenzhen A-shares from 2012 to 2021 as a sample, and adopts an empirical research methodology, which reveals that the effectiveness of internal control is negatively related to the trend of share price crash, and efficient internal control is positively related to the transparency of corporate information environment. The findings suggest the impact of internal control on the risk of stock price crash at the individual stock level and provide empirical support for listed companies to manage their risks. This study has practical value in guiding listed companies to strengthen internal control, improve information transparency, mitigate the risk of stock price crashes, and provide a decision-making basis for the healthy and stable development of the capital market.

Published: May 2024

Plastic pollution in the hydrosphere ranks among the most pervasive environmental issues since the inception of the plastic industry and its widespread use in our daily lives. Nowadays, numerous countries worldwide suffer from this pollution not only along coastlines but also in deep-sea ecosystems. Our study carried out in the Gulf of Annaba aims to assess the prevalence and spatial distribution of plastic waste. Sampling was conducted at four coastal sites: El Battah, Seybousse, Rizzi Amor, and Ain Achir, both before and after the Covid-19 pandemic. The results reveal varying rates of macro and microplastic contamination, influenced by geographical differences, urban activities, and hydrodynamic factors. Moreover, the proportions of contamination depend on the types of waste. Furthermore, our study showed a clear divergence, particularly in two periods before and after the pandemic. Due to the lockdown, implemented in 2020, there was a marked decrease in the percentage of sediment plastic pollution, attributed to reduced human activity and partial cessation of industrial operations in these areas.

Published: May 2024

The investigation of Nida Valley water aimed to assess fluctuations in physicochemical properties. In this study, environmental monitoring method was utilized to evaluate the changes in physicochemical properties of water. Over a 24-month period, from June 2021 to May 2023, a total of 228 water samples were collected from 10 sampling sites, with a monthly sampling frequency. Statistical analyses were utilized including the Shapiro–Wilk test (α = 0.05), Kruskal–Wallis test and Wilcoxon (Mann–Whitney) rank sum test (α = 0.05), Pearson correlation analysis (α = 0.001) and principal component analysis (PCA). Statistical analyses revealed significant differences between months in GW samples for for temperature, dissolved oxygen, pH, total nitrogen, total phosphorus, chloride, manganese, and zinc in GW samples and for T and DO in SW samples. Pearson correlation coefficient analysis (α = 0.001) identified strong positive correlations within the SW dataset. Similarly, significant positive correlations were observed among the GW dataset. Noteworthy positive correlations were also detected between the GW and SW datasets. Principal component analysis (PCA) revealed a substantial dissimilarity between GW2 samples compared to others, characterized by elevated manganese, iron, and Sulfate content. Two distinct groups emerged: Group 1 included samples at GW1, GW2, GW3, GW5, and SW2, while Group 2 comprised all other samples. This study demonstrated the stability in the physicochemical properties of SW and underscore a discernible correlation between the hydrochemical compositions of both SW and GW in the riparian area. Outstanding characteristics in hydrochemical component of sample waters have been indicated.
Influence of build orientation on porosity, strength and dimensional accuracy of laser sintered polyamide porous bone scaffolds
Authors: Gorana Falguni , Modi Yashwant Kumar
Published: May 2024

Development of synthetic bone graft via bone tissue engineering involves seeding of patient’s stem cells onto a porous scaffold in presence of growth factors. Porosity, strength and dimensional accuracy of the porous scaffold play a vital role in this process. This work aims at ascertaining influence of build orientation on porosity, mechanical strength and dimensional accuracy of the selectively laser sintered polyamide porous scaffolds. Initially, CAD models of test specimens with pre-designed porosity were created in Solidworks® software. All the specimens were fabricated on EOSINT P395, a selective laser sintering machine, along various primary (Flat, Edge, Upright and Flat_diag) and secondary (0o, 30o, 45o, 60o and 90o) orientations. Results show that measured porosity of most of the specimens was (range: 42.89-35.26%) less than the designed porosity (41.71%). Maximum average tensile strength (16.84 MPa) was recorded for specimens printed along Flat_0o orientation. Specimens printed along Upright_90o orientation showed highest average compressive strength (8.26 MPa). Specimens printed along Flat orientation showed relatively better average impact strength. Best dimensional accuracy was obtained for specimens printed along Flat orientation.
Noncombat injury and illness prevalence and working score percentage quantify the impact on duty availability in US Army Special Operations military working dogs
Authors: Harroun-White Hailey E. , Facciolla Cynthia A. , Knobbe Marc G.
Published: May 2024

OBJECTIVE

This cross-sectional study determined the 2-year period prevalence and quantified the impact on working status of noncombat injury and illness by a working score percentage (WSP) based on the number of duty days lost (DDL).

ANIMALS

126 dogs from 9 US Army Special Operations kennels.

METHODS

Dog injury and illness events between May 1, 2021, and April 30, 2023, were recorded to determine period prevalence and calculate a WSP metric to quantify loss of duty status.

RESULTS

93 health events occurred in 62 of 126 (49.2%) dogs over a 24-month period resulting in 4,130 DDL. The period prevalence was 25 of 126 (19.8%) for dental injuries, 20 of 126 (15.9%) for musculoskeletal injuries, and 13 of 126 (10.3%) for gastrointestinal illnesses. Musculoskeletal conditions resulted in the highest total DDL at 1,472 (35.6%) in 20 dogs, followed by neurologic conditions at 950 (23%) in 4 dogs and heat injuries at 521 (12.6%) in 7 dogs. The total population 24-month mean WSP was 88.1% (95% CI, 86.6 to 89.5). The mean WSP for 43 dogs with acute events was 96.0% (95% CI, 95.0 to 97.0), and the mean WSP for 14 dogs with chronic events was 55.2% (95% CI, 47.8 to 62.5).

CLINICAL RELEVANCE

Quantifying the impact of noncombat illness and injury on the working status of military working dogs is the first step to identify risk factors, develop preventive strategies, resource veterinary care requirements, and improve these canine athletes’ health and welfare. The metrics developed in this study can be used to evaluate the population health of working, herding, and sport dogs.
A study on the correlation between the digital economy and resource allocation efficiency in the context of factor mobility
Authors: Zhang Yongcai
Published: May 2024

In the context of the rapid development of the Internet, the digital economy has become an important growth engine, which has an important impact on the optimization of resource allocation. This paper takes the digital economy for resource allocation efficiency as the research framework and explores the impact mechanism of the digital economy from the perspective of factor flow. After relevant data research, the development capacity of the digital economy has an important positive impact on both capital and labor dimensions in terms of resource allocation, and the digital economy can balance the way of resource allocation in different regions under the perspective of factor mobility. The current analysis of regional heterogeneity shows that the impact of the digital economy in China’s inland regions is higher than that in China’s coastal regions. Based on the above conclusions, this study suggests that it is necessary to further develop digital technology, promote the deepening reform of government policies, regulations, and institutions, and promote the reform of the factor market, to enhance the efficiency enhancement of the digital economy in the allocation of resources.

Anatomic considerations during placement of mandibular retromolar miniplates for orthodontic anchorage – A study of the characteristics of retromolar fossa
Authors: Sharma Pooja Navin , Sabrish Sharanya , Prashantha G. S. , Sagarkar Roshan , Mathew Silju , Krishnamurthy Sathyashree
Published: May 2024

Objectives:

The mandibular retromolar area offers a novel site for orthodontic skeletal anchorage. It houses the retromolar foramen (RMF), and surgical interventions in this area can lead to undesirable outcomes. This study aims to assess the characteristics of the RMF and its relation to the occlusal plane (OP) using cone-beam computed tomography (CBCT) data.

Material and Methods:

This cross-sectional observational in vitro study involved the analysis of CBCT data from 136 samples (68 males and 68 females) within the age range of 18–40 years. The study focused on factors such as the presence or absence of the RMF, whether it was unilateral or bilateral, the number of foramina on each side, and the distance of the RMF from the OP. Data analysis was conducted using the Statistical Package for the Social Sciences software, with P < 0.05 deemed statistically significant at a 95% confidence level.

Results:

About 39% of the sample showed the presence of RMF. The prevalence of unilateral RMF was higher than that of bilateral RMF. The mean distance of RMF above the OP was 5.99 mm, and that below the OP was 3.82 mm.

Conclusion:

The high prevalence (39%) of RMF suggests that the retromolar fossa region should be evaluated before the placement of mini-plates. The prevalence of RMF above the OP was significantly higher than that below the OP.
A case of loose anagen hair syndrome associated with trichotillomania in a 14-year-old girl
Authors: Thomas Naveen , Francis Johny Vakayil , Athira R.
Published: May 2024

Loose anagen hair syndrome (LAHS) and trichotillomania (TTM) are two distinct conditions. LAHS is a rare condition characterized by easily removable anagen hair without any sensation of pain. It primarily affects young girls and is associated with a sparse hair growth and a delicate hair texture. LAHS can occur spontaneously or be inherited in an autosomal recessive manner. On the other hand, TTM, also known as hair pulling disorder, is an obsessive-compulsive disorder characterized by the recurrent, overwhelming urge to repeatedly pull out one’s hair. Hair pulling can occur anywhere on the body but is most common on the scalp, eyebrows, and eyelashes and subsequently results in bald patches. It is linked to psychosocial impairment and a decrease in the overall quality of life. We present a case of 14-year-old female with a longstanding history of sparse and disorderly hair since childhood due to LAHS associated with TTM. Treatment involved topical minoxidil and psychiatric counseling, resulting in significant improvement initially. However, a relapse was observed a year later, emphasizing the complexity of managing this dual pathology.
Semen Cryopreservation in Oncofertility
Authors: Muthukumar Shruthivishali , Tholeti Prathima
Published: May 2024

Oncofertility, an interdisciplinary field, aims at improving the uality of life of cancer patients prone to iatrogenic infertility by offering fertility preservation options for a potentially fertile future. Semen cryopreservation (SC) is a well-established and effective way of preserving fertility in adolescent and young adult cancer-diagnosed males as they face potential fertility loss due to cancer and its treatments. The pathophysiology of certain cancers, such as testicular cancer or Hodgkin’s lymphoma, has been shown to have an adverse effect on semen uality. Ablative therapies like chemotherapy and radiotherapy can result in compromised sperm parameters depending on the dose and the type of the drug or radiation. Hence, it is recommended to encourage cancer-diagnosed males to store sperm prior to gonadotoxic therapy to restore potential fertility in the future. Despite the feasibility of SC, this option remains underutilised due to several limitations.
Intrasellar chordoma masquerading as a pituitary neuroendocrine tumor: Illustrative case
Authors: Sato Daisuke , Hasegawa Hirotaka , Kimura Soichiro , Sato Junichiro , Shinya Yuki , Umekawa Motoyuki , Yasunaga Yoichi , Makita Noriko , Saito Nobuhito
Published: May 2024

Background:

Chordomas are rare, locally aggressive neoplasms recognized as derivatives of the notochord vestiges. These tumors typically involve the midline axial skeleton, and intracranial chordomas exhibit proclivity for the spheno-occipital region. However, purely intrasellar occurrences are extremely rare. We report a case of intrasellar chordoma, which masqueraded as a pituitary neuroendocrine tumor.

Case Description:

An 87-year-old female presented with an acutely altered mental state after a few-week course of headaches and decreased left vision. Adrenal insufficiency was evident, and magnetic resonance imaging revealed an intrasellar lesion with heterogeneous contrast enhancement and marked T2 hyperintensity. Central adrenal insufficiency due to an intrasellar lesion was suspected. Cortisol replacement was initiated, and transsphenoidal surgery was performed. Anterosuperior displacement of the normal pituitary gland and the absence of the bony dorsum sellae were notable during the procedure. Histological examination led to a diagnosis of conventional chordoma, and upfront adjuvant stereotactic radiosurgery was executed. She has been free from tumor progression for 12 months.

Conclusion:

This case and literature review suggested that the pathognomonic features of intrasellar chordoma were heterogeneous contrast enhancement, marked T2 hyperintensity, osteolytic destruction of the dorsum sellae, and anterosuperior displacement of the pituitary gland. Clinical outcomes seemed slightly worse than those of all skull base chordomas, which were the rationale for upfront radiosurgery in our case. Neurosurgeons should include intrasellar chordomas in the differential diagnosis of intrasellar lesions, carefully dissect them from the adjacent critical anatomical structures, and consider upfront radiosurgery to achieve optimal patient outcomes.

Methods:

A 61-year-old underwent an open esophageal diverticulectomy for symptomatic Zencker’s diverticulum.

Results:

Postoperatively, she presented with right upper extremity weakness and sensory deficits consistent with a C5P that was later confirmed by electromyography.

Conclusion:

The potential for C5P after esophageal diverticulectomy for symptomatic Zencker’s diverticulum is rare. Postoperative recognition and appropriate management are critical to recovery.
Meningioma recurrence: Time for an online prediction tool?
Authors: Albakr Abdulrahman , Baghdadi Amir , Karmur Brij S. , Lama Sanju , Sutherland Garnette R.
Published: May 2024

Background:

Meningioma, the most common brain tumor, traditionally considered benign, has a relatively high risk of recurrence over a patient’s lifespan. In addition, with the emergence of several clinical, radiological, and molecular variables, it is becoming evident that existing grading criteria, including Simpson’s and World Health Organization classification, may not be sufficient or accurate. As web-based tools for widespread accessibility and usage become commonplace, such as those for gene identification or other cancers, it is timely for meningioma care to take advantage of evolving new markers to help advance patient care.

Methods:

A scoping review of the meningioma literature was undertaken using the MEDLINE and Embase databases. We reviewed original studies and review articles from September 2022 to December 2023 that provided the most updated information on the demographic, clinical, radiographic, histopathological, molecular genetics, and management of meningiomas in the adult population.

Results:

Our scoping review reveals a large body of meningioma literature that has evaluated the determinants for recurrence and aggressive tumor biology, including older age, female sex, genetic abnormalities such as telomerase reverse transcriptase promoter mutation, CDKN2A deletion, subtotal resection, and higher grade. Despite a large body of evidence on meningiomas, however, we noted a lack of tools to aid the clinician in decision-making. We identified the need for an online, self-updating, and machine-learning-based dynamic model that can incorporate demographic, clinical, radiographic, histopathological, and genetic variables to predict the recurrence risk of meningiomas.

Conclusion:

Although a challenging endeavor, a recurrence prediction tool for meningioma would provide critical information for the meningioma patient and the clinician making decisions on long-term surveillance and management of meningiomas.

Published: May 2024

Background:

Trigeminal neuralgia (TN) is a debilitating disease with an annual incidence of approximately 4–27/100,000. In Ontario, over 2000 patients receive interventions for profound pain, including medical and surgical therapies. The global expected cost of these approaches is unknown. This study aims to analyze the cost-effectiveness of one surgical therapy, microvascular decompression (MVD), compared with the best medical therapy (carbamazepine) as first-line therapy.

Methods:

Costs were gathered from the Canadian Institute for Health Information, Ontario Drug Benefit Formulary, and Ontario Ministry of Health Schedule of Benefits for Physician Services. Academic literature was used to estimate unavailable items. A cost-benefit Markov model was created for each strategy with literature-based rates for annual cycles from years 1 to 5, followed by a linear recurrent cycle from years 6 to 10. Incremental cost-effectiveness ratios (ICERs) were calculated based on the incremental cost in 2022 Canadian Dollars (CAD) per pain-free year.

Results:

Base case cost per patient was $10,866 at 10 years in the “MVD first” group and $10,710 in the “carbamazepine first” group. Ten-year ICER was $1,104 for “MVD first,” with strict superiority beyond this time point. One-way deterministic sensitivity analysis for multiple factors suggested the highest cost variability and ICER variability were due to surgery cost, medication failure rate, and medication cost.

Conclusion:

Economic benefit is established for a “MVD first” strategy in the Ontario context with strict superiority beyond the 10-year horizon. If a cost-effectiveness threshold of $50,000 per pain-controlled year is used, the benefit is established at 4 years.
Operation of Amorphous TiO2 Protected Photocathodes Described with the Maxwell Equivalent Circuit
Authors: Service Erin , Moehl Thomas , Tilley David
Published: May 2024

The use of amorphous TiO2 (a-TiO2), deposited by atomic layer deposition (ALD), is a common strategy to protect semiconductors from degradation when used in water splitting photoelectrochemical (PEC) cells. Electrochemical impedance spectroscopy (EIS) is a suitable technique to study these PEC cells as it is capable of deconvoluting multiple processes occurring during operation, therefore providing information about mechanisms leading to overall device performance. When biased under hydrogen evolution conditions, EIS shows that two simultaneous processes occur in a-TiO2 protected photocathodes, which introduces an ambiguity in choosing the correct equivalent circuit to describe the operating device. In this report, a model p-Si|a-TiO2|Pt photocathode system is used to show that the Maxwell circuit best describes the operating mechanism, as opposed to the more commonly used Voight and nested circuits. This indicates that under hydrogen evolution conditions, both faradaic and non-faradaic processes are occurring. Whereas the faradaic process corresponds to the hydrogen evolution reaction itself, the non-faradaic process is traced to the p-Si|a-TiO2 interface.
Sub-picosecond Dynamics of Rydberg Excitons Produced from Ultraviolet Excitation of Neutral Cuprite (Cu2O)n Clusters, n < 13

Published: May 2024

The ultrafast dynamics of sub-nanometer neutral cuprite clusters (Cu2O)n, n < 13, are examined with pump probe spectroscopy. Up-on absorption of an ultraviolet (400 nm) photon, all clusters exhibit a sub-picosecond lifetime that we attribute to carrier recombi-nation. Density functional theory shows a change in the structural motif between small planar clusters and three-dimensional struc-tures at n = 4. This transition is accompanied by a change in the excited state relaxation behavior, marking the onset for which life-times increase gradually with size. Time-dependent density functional theory calculations show the excited state lifetimes align with calculated topological parameters and charge carrier delocalization associated with the formation of Rydberg excitons. Termi-nal Cu atoms are found to be important for the production of Rydberg excitons at the lowest optically allowed excited state. The electron centers on terminal Cu atoms and the hole becomes delocalized across the remainder of the cluster.
Charting the Electronic Structure for Discovering Low-cost Intermetallic Catalysts
Authors: He Zhengda , Ouyang Bin
Published: May 2024

Discovering affordable, high-performance, and stable catalysts for the hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR) is essential for the commercialization of clean hydrogen technology. In this study, we utilized a high-throughput screening approach combined with electronic structure descriptors to identify new intermetallic catalysts that minimize noble metal contents while maintaining high performance and stability. We screened 2,358 binary and ternary intermetallic compounds constructed from 31 common transition metal elements. From the 462 bulk compositions that are synthetically accessible, we enumerated all possible low-Miller-index surfaces (12,057 surfaces in total) with density functional theory calculations. Seven electronic-structure-based descriptors are then applied to pinpoint aqueously stable surfaces offering performance comparable to the renowned Pt (111) and Ir (111) surfaces. This process led to the identification of several previously known noble-metal-containing catalysts, as well as a selection of new intermetallic catalysts.
Reimagining Enantioselective Aminoalcohol Synthesis via Chemoselective Electrocatalytic Radical Cross Couplings

Published: May 2024

Aminoalcohols are expressed in natural products, blockbuster pharmaceuticals, agrochemicals, and key building blocks for innumerable society-benefitting applications. Historically their synthesis relies on polar-bond retrosynthetic analysis and often suffers from extensive protecting/functional group manipulation chemistry that hinders their direct access. Here we show how a simple serine-derived chemical cassette can be leveraged in a series of electrocatalytic transformations to dramatically simplify the way such structures can be made enantio- and chemoselectively in a modular fashion. This chemistry can be used to rapidly create libraries of useful building blocks and the radical retrosynthetic logic employed can be applied to truncate the synthesis of known structures. This methodology can be used on large scale as well as demonstrated with a unique flow reactor setup.
Different role of ruthenium and platinum defective sites on the catalytic activity for the hydrogen evolution reaction

Published: May 2024

The reduction of protons to H2 (the hydrogen evolution reaction, or HER) is one of the two half reaction of water electrolysis. It produces H2 that can be used as energy vector or sustainable feedstock for other compounds. Platinum electrodes are the “golden standard” catalysts. However, due to Pt cost, there is a need for cheaper alternatives. Indeed, highly active ruthenium nanoparticles are promising alternative. In this contribution, we use DFT (PBE-D2) calculations to understand the differences in the catalytic activities of Ru and Pt materials by considering slab models containing crystalline close packed planes, terraces, steps, islands and adatoms. Results reveal that the strong adsorption of isolated H atoms on either material and on various sites prevents the hydrogen evolution reaction from taking place. Regardless of the model considered, the formation of a monolayer is also too favorable, thus suggesting that higher coverages are needed before HER onset. The adsorption energies of H atoms exceeding the monolayer on platinum's crystalline surfaces, defective steps and terraces are very close to the ideal value, consistent with platinum's high catalytic activity. These results outline that the presence of lowly coordinated metal centers has little effect on the reactivity of Pt. The adsorption energy of extra H on Ru surfaces depends on the adsorption site: On non-defective sites, the adsorption of the extra H is unfavorable, leading to inefficient catalysts. In contrast, the adsorption on defective sites is favorable and close to the ideal value, thus suggesting an enhancement of the catalytic activity when Ru coordination decreases. These results outline that the reactivity toward hydrogen of Ru materials is more sensitive to surface morphology than Pt-based ones. Indeed, the presence of low coordinated centers is larger on Ru nanoparticles, thus rationalizing their high HER catalytic activity.
