Abstract
Background Blood product ordering is a complex process and mistakes can harm patients and lead to poor outcomes. Orders and order sets can be designed to help mitigate errors, but major changes in design can unintentionally cause new errors.
Objectives Our objective was as follows: (1) utilize formative in situ usability testing to iteratively improve the design of a redesigned blood product order set prior to go-live, (2) implement changes based on feedback derived from this testing, and (3) compare the error rate, system usability scale (SUS) score, time to task completion, and click counts between the prior order set in use at the time and the revised redesigned order set.
Methods A multidisciplinary project team convened to redesign blood product orders and order sets from scratch based on a review of the literature and benchmarking against four pediatric academic institutions with the goal of addressing prior ordering errors. The newly redesigned blood product order set was iteratively updated via in situ formative usability testing performed with available clinical users using a concurrent think-aloud protocol in real clinical environments. Errors, SUS scores, time to task completion, and click counts were assessed for the revised redesigned order set using summative testing.
Results Formative usability testing with 20 participants led to seven design changes in the redesigned order set which reduced the error rate at go-live. Summative usability testing showed that even though the usability scores were only slightly improved for the revised redesigned order set, the error rates in blood orders were significantly decreased.
Conclusion Usability testing can identify design errors early in the process which can be rectified prior to implementation, thus avoiding unintended consequences of changes.

AbstractThe majority of meningiomas are slow-growing benign tumors that can potentially be highly vascularized; however, acute hemorrhagic onset is rare. Herein, we describe two patients who presented with disturbance of consciousness and severe hemiplegia due to spontaneous hemorrhage from a falx atypical meningioma. A 49-year-old female presenting with a sudden disturbance of consciousness and severe left hemiplegia was found to have a falx meningioma and acute hemorrhage. Emergent resection achieved neurological relief and tumor control. A 60-year-old female with aphasia and severe right hemiplegia also had falx meningioma and hematoma, and successfully treated by emergent resection. Tumor was diagnosed as atypical meningioma in both cases. Both patients achieved mid-term tumor control for 4 and 7 years. Both patients were treated successfully with emergent surgical resection, and neurological relief and mid-term tumor control (7 and 4 years, respectively) were achieved. Given this success, immediate surgical resection with hematoma evacuation should be considered an acceptable therapeutic option for acute hemorrhagic atypical meningioma.

AbstractContrecoup brain injury refers to the classical opposite of the primary impact. Tamil Nadu has the highest rate of road traffic accident in India. Madurai has peak mortality due to accidents in India. Previous studies done on contrecoup head injury had shown patterns of injuries and mechanism of injury. Outcome and management of only occipitofrontal contrecoup head injury has been taken in this study. Mortality in this specific group is very high. Seventy-six patients of this specific head injury were admitted at Government Rajaji Hospital, Madurai. Patients were assessed for Glasgow coma scale (GCS), age, sex, progression of volume, mortality, traumatic brain injury-induced coagulopathy, and pillion rider outcome. Fourteen patients were surgically treated by decompressive craniectomy. Conservative management was done by antiepileptic and antiedema measures. Mostly affected were males (n = 54) followed by females (n = 22). GCS on admission mean value 9. In our study, mortality was 32% with sudden death of three patients due to hypothalamic compression. Hospital stay of the patient was significantly increased with progression of lesion with mean 9 days and p-value less than 0.01. Pillion riders (n = 18) were also affected in our study. Traumatic brain injury-induced coagulopathy (n = 12) was also detected, which was treated by injection tranexamic acid and injection vitamin K, thereby not leading to any death due to coagulopathy with significant p-value less than 0.01. We recommend helmet for both main and pillion rider with strict speeding regulations.
Polyp Endotherapy for Multiple Jejunal Lipomas Presenting as Small Bowel Intussusception: “Loop and Let Go Technique”
Authors: Achanta Chalapathi R. , Kinhal Sudhanva V. 
Published: June 2024

AbstractA 46-year-old woman presented with abdominal pain, vomiting, and intermittent constipation for the last 2 days. She had similar history of recurrent symptoms for the last 6 months. Abdominal examination showed mild central abdominal tenderness and generalized abdominal fullness and no palpable mass. A diagnosis of intestinal obstruction was considered. Nasogastric aspiration was performed with intravenous (IV) antibiotics and IV fluids. Computed tomography (CT) scan of the abdomen showed “bowel in bowel” or “target” sign appearance of jejunum with a submucosal hypodense lesion (suggestive of lipoma) acting as the lead point. There were two more submucosal lipomas of sizes approximately 3 cm each in the distal jejunal loops. A diagnosis of jejunal lipomas causing small bowel intussusception was made. The patient improved with conservative management. Exploratory laparotomy was planned with an intent to resect the small bowel. The patient did not provide consent for the same and so the option of enteroscopy-guided polyp endotherapy was offered to the patient. An antegrade single balloon enteroscopy was done (SIF-Q180, Olympus Medical Systems, United States). Three submucosal lesions with smooth overlying mucosa were noted in the mid and distal jejunum consistent with lipomas. The base of the lesions was ligated tightly using endoloop to make them ischemic and detach. Notable changes in color and mucosal appearance were noted after the application of endoloop. Since all the lipomas detected on cross-sectional radiologic imaging have been tackled via antegrade route, a retrograde enteroscopy was not attempted further. After 2 days, the patient was discharged in stable condition. Follow-up cross-sectional imaging at 3 months showed no residual lipomas, and she remained symptom-free at the end of 6 months.

Published: June 2024

AbstractBow Hunter's syndrome (BHS) is a very rare condition in which there is rotational vertebral artery (VA) insufficiency. The association of BHS with rotational atlantoaxial instability is extremely rare. We are reporting a case of pediatric BHS who presented with features of VA insufficiency on neck rotation. Careful evaluation revealed rotational C1-C2 instability. Provocative digital subtraction angiography and dynamic neck computed tomography were the mainstay of our diagnostic armamentarium. Our case emphasizes the fact that VA abnormalities need special consideration in young patients with craniovertebral junction instability and a high degree of suspicion is necessary in most instances for accurate diagnosis.

Published: June 2024

AbstractThis research scrutinizes the trends and dynamics of Intellectual Property Protection (IPP) of Intangible Cultural Heritage (ICH) in China, utilizing a dataset of 91 papers from the CNKI database spanning 2011 to 2020. The study uses CiteSpace software to visualise and analyse the literature across multiple dimensions, including article count, authorship, institutional affiliations, and keyword co-occurrence. Findings indicate a lack of robust collaboration among authors and institutions in IPP and ICH, with a scarcity of active cooperative groups. Critical research hotspots identified encompass intangible cultural heritage, intellectual property protection, inheritors, legal protection, copyright, intellectual property law, and geographical indications, with the legal safeguarding of ICH’s intellectual property, digital conservation, traditional cultural expressions, and original authentication emerging as the leading research frontiers. This investigation provides a holistic view of China’s IPP and ICH landscape, offering essential scientific insights for ongoing scholarly discourse. This study mainly benefits policymakers and stakeholders in the cultural heritage sector, underscoring the necessity of enhanced authorial and institutional collaboration and the prioritization of legal and digital protection mechanisms to safeguard China’s intangible cultural legacy for posterity. The analysis is critical, informing policy formulation and strategic planning to bolster ICH’s protection and sustainable management in China.
A topological drive for spacetime travel
Authors: Cai Tingqi , Wang Yi 
Published: June 2024

Abstract
We present a toy metric of spacetime travel from topological change. A bubble-like baby Universe is detached and re-attached from our Universe. Depending on where the bubble is re-attached, matter may travel superluminally or backwards-in-time through the bubble. Quasiregular singularities are formed at the detachment and re-attachment spacetime points. The spacetime is traversable and not covered by any horizons. Exotic matter violating energy conditions is required to realize such spacetimes.

Published: June 2024

Abstract

Objective. Physiological signals based emotion recognition is a prominent research domain in the field of human-computer interaction. Previous studies predominantly focused on unimodal data, giving limited attention to the interplay among multiple modalities. Within the scope of multimodal emotion recognition, integrating the information from diverse modalities and leveraging the complementary information are the two essential issues to obtain the robust representations. Approach. Thus, we propose a intermediate fusion strategy for combining low-rank tensor fusion with the cross-modal attention to enhance the fusion of electroencephalogram, electrooculogram, electromyography, and galvanic skin response. Firstly, handcrafted features from distinct modalities are individually fed to corresponding feature extractors to obtain latent features. Subsequently, low-rank tensor is fused to integrate the information by the modality interaction representation. Finally, a cross-modal attention module is employed to explore the potential relationships between the distinct latent features and modality interaction representation, and recalibrate the weights of different modalities. And the resultant representation is adopted for emotion recognition. Main results. Furthermore, to validate the effectiveness of the proposed method, we execute subject-independent experiments within the DEAP dataset. The proposed method has achieved the accuracies of 73.82% and 74.55% for valence and arousal classification. Significance. The results of extensive experiments verify the outstanding performance of the proposed method.
Investigating and predicting tribological characteristics of AZ31 alloy composites reinforced with nano-Al2O3 and micro-Sn particles: a comparative analysis using CCD-RSM and ANN models
Authors: Ajay C Veera , Manisekar K , Andrews A 
Published: June 2024

Abstract
In this research, the central composite-based response surface methodology was adopted to select the dominant optimal input factors on wear behaviour and coefficient of friction of an AZ31-microtin/2 wt% nano-Al2O3 composite prepared through a stir casting process with different wt% of Sn. The input factors, such as wt% of Sn reinforcement, sliding distance, sliding speed, and applied load, were selected to determine their significant effects on the coefficient of friction and wear behaviour with 30 trial runs. Analysis of variance (ANOVA) results indicated that Sn reinforcement plays a significant role in the wear behaviour of the nanocomposites, followed by applied load and sliding distance. In addition, an enhancement in wear resistance was witnessed by the addition of Sn reinforcement with AZ31/nano-Al2O3 composites. The optimal process parameters as per the desirability approach were found to be a weight percentage of Sn: 8%, load: 20 N, sliding speed: 2 m s−1, and sliding distance: 1000 m. According to the ANN results, the predicted data is perfectly acceptable with the actual experimental response value. The R values for the training, validation, and testing phases are 0.96166, 0.96801, and 0.98914 for COF, and 0.97688, 0.99247, and 0.99331 for wear rate, indicating a robust correlation between predicted and actual values. The worn-out pin samples were used to examine the worn surface morphology and analyze the wear mechanism.

Abstract
We analyze correlation structures in financial markets by coarse graining the Pearson correlation matrices according to market sectors to obtain Guhr matrices using Guhr’s correlation method according to P Rinn et al (2015, Europhysics Letters
110, 68 003). We compare the results for the evolution of market states and the corresponding transition matrices with those obtained using Pearson correlation matrices. The behavior of market states is found to be similar for both the coarse grained and Pearson matrices. However, the number of relevant variables is reduced by orders of magnitude.
Enhancement of SPR effect and sensing characteristics of no-core fiber with bubble structure
Authors: Yin Zhiyong , Jing Xili , Pei Menglei 
Published: June 2024

Abstract
In this work, we propose the SPR fiber sensor based on a bubble structure. Conventional SPR optical fiber sensors have an anomalous broadening of the resonance dip in the near-infrared band. Therefore, we propose to utilize a bubble structure to improve the FWHM of the spectrum. The sensor utilizes no-core fiber as the sensing platform and multimode fiber as the transmission fiber, and fabricates a bubble at the fusion of the two fibers. The effect of bubble size on the SPR effect is investigated experimentally, and the results show that bubbles can improve the sensitivity and reduce the FWHM of SPR sensor. The refractive index sensing test was implemented on the proposed SPR bubble sensor. The experimental results showed that the bubble structure enhanced the maximum sensitivity of the SPR sensor by 927.7 nm/RIU. Finally, the effect of the bubble on the response time of the sensor is discussed. The method of using a bubble structure to improve sensor performance is simple to operate and easy to implement.

Abstract
As hydrogen fuel cell vehicles enter the public eye, it is necessary to develop reasonable hydrogen station layouts and capacity plans to predict and meet future hydrogen fuel demands. This article employs a classical flow capture model with the objectives of minimizing the unit cost of hydrogen station networks and maximizing the capture rate of regional traffic flows. Through the improvement of genetic algorithms for simulation, the study determines the location of hydrogen stations and calculates their corresponding scales. In the end, the hydrogen station network is obtained with a unit hydrogen cost of 11.60 yuan/kg and a traffic capture rate of 90.47%. The research results validate the effectiveness of the proposed model, providing a reference for the investment and construction of future hydrogen stations.
Preparation and application method of CNTs dispersion solution for direct electroplating on circuit board holes
Authors: Yu Jihong , Yang Jie 
Published: June 2024

Abstract
The utilization of carbon black dispersion solutions for the black hole method is common in the electronics industry due to their cost-effectiveness and stable performance. However, the slow electroplating speed caused by carbon black’s poor conductivity can impact industrial processes and time. This paper introduces a water-based dispersion solution of carbon nanotubes (CNTs) for the direct copper electroplating process on circuit board holes and its application method. The dispersion solution comprises “shortened” CNTs with a small aspect ratio, a dispersant, a pH adjuster, and other optimization agents. This black hole liquid functions as a conductive fluid with “shortened” CNTs as the conductive medium, exhibiting high dispersibility, strong through-hole capability, low resistance, and excellent adhesion. Its performance surpasses that of black hole liquids using single-carbon black as the conductive medium. The key advantage lies in avoiding the entanglement associated with conventional long aspect ratio CNTs, thereby enhancing the conductivity of the water-based dispersion solution. This facilitates the formation of a uniform conductive film through the electrostatic self-adsorption method, which is suitable for preparing a conductive film on circuit board hole walls before copper electroplating.

Published: June 2024

Abstract
The NO
x
emissions and combustion performance of pure ammonia and hydrogen-doped combustion (90% NH3 volume fraction and 10% H2 volume fraction) in the cyclone combustion chamber were comprehensively analyzed through numerical simulations under varying thermal operating conditions. The findings reveal that the flame characteristic length in hydrogen-doped combustion surpasses that in pure ammonia combustion, indicating an extended migration of the high-temperature zone after hydrogen doping. Furthermore, the addition of hydrogen results in an elevated exhaust temperature within the combustion chamber, while the Outlet Temperature Distribution Function (OTDF) decreases, signifies an enhancement in the uniformity of temperature distribution at the outlet. Moreover, the reflux zone experiences less impact, and the mixed gas velocity increases following hydrogen doping. Notably, NO
x
emissions demonstrate a significant decrease after the addition of hydrogen. The average NO emission concentration in pure ammonia combustion, under various operating conditions, is measured at 212.47 mg/m3, representing a 3.51-fold increase compared to hydrogen-doped combustion.

Abstract
SPIDER (Source for the Production of Ions of Deuterium Extracted from a Radio frequency plasma) is currently in a major shutdown period dedicated to the upgrade of several components in order to enhance its performances and guarantee their agreement with the ITER requirements. During this phase, an in-depth inspection of the beam source components is fundamental to understand SPIDER behaviour during the previous experimental campaigns, and in particular caesium evaporation inside the source by means of Cs ovens. Caesium evaporation and its deposition on the plasma grid (PG) is fundamental to minimize the work function of PG surface causing an increased generation of negative ions and a reduction of the electron density in front of the PG, which means less co-extracted electrons. This work presents the analysis of the caesium ovens performances and of their status after removal. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analyses were carried out on samples of plasma source walls, and the experimental data was compared to the results obtained from other investigations: numerical models for the caesium evaporation and deposition, chemical surface analyses (performed in strategical locations of the source walls and extraction grid), and Laser Absorption Spectroscopy (LAS) measurements. The non-uniformity of Cs distribution has been taken into account since it has repercussions on negative ion extraction efficiency and uniformity.

Abstract
A cryogenic scintillating bolometer demonstration experiment utilizing Li2MoO4 crystals is proposed for exploring neutrinoless double beta decay (0νββ) at China Jinping Underground Laboratory (CJPL). The hardware and software framework R&D for the entire detection system is currently in progress. In this study, we present a comprehensible offline data processing software designed for this project. The software facilitates event trigger and reconstruction by applying an optimal filter and Monte Carlo truth stream data generator. Based on the simulated stream data, a significant noise suppression and an increase on energy resolution are obtained, with an improvement of approximately 40% comparing to that estimated from the original pulse waveform.
