Staged dissection reduces blood loss in surgery for metopic synostosis.

Fronto-orbital remodelling for metopic synostosis is an extensive operation with substantial blood loss, particularly from emissary veins in the glabellar region. One possibility to reduce blood loss may be to stage dissection and cauterise anomalous emissary veins before dissecting in the subperiostal plane. OBJECTIVE: The aim of the present study was to compare perioperative bleeding using a staged dissection in the glabellar region with the traditional subperiostal dissection technique during surgery for metopic synostosis. All consecutive patients operated for metopic synostosis with the new staged dissection technique (T2) were included. For comparison, the most recent equal number of cases operated with the traditional dissection technique (T1) were included. Age, sex, weight, surgical technique (spring or bone graft), perioperative blood loss, perioperative blood pressure, per- and postoperative blood transfusion, operation time and length of hospital stay were registered. RESULTS: A total of 80 patients were included; 40 T1 and 40 T2, respectively. Perioperative blood loss was significantly reduced with the new staged dissection technique. Blood loss in absolute numbers was reduced from 160.0 (120-240) (median and (interquartile range)) ml to 150 (102.5-170.0) ml, p=0.028. Blood loss in relation to patient weight was reduced from 24.2 ml/kg (15.3-33.3) to 18.7 (16.6-23.1) ml/kg, p=0.024. As percentage of total blood volume, blood loss was reduced from 32.3 (20.3-32.3) % to 29.9 (18.4-30.8) %, p=0.024. No other variables differed significantly between the techniques. CONCLUSION: In summary, staged dissection technique in the glabellar region, allowing control of the emissary veins, reduces perioperative blood loss during surgery for metopic synostosis.

Diffraction‐Driven Parallel Convolution Processing with Integrated Photonics

AbstractTraditional electronic processors often struggle with bandwidth limitations and high power consumption when executing extensive linear operations for deep learning tasks. Optical computing has emerged as a promising alternative, offering parallel and energy‐efficient computation capabilities. Yet, the development of high‐density optical computing architectures on integrated photonic platforms remains limited, hindered by constraints in neuron scalability and control engineering complexities. Addressing these challenges, this work presents a diffraction‐driven multi‐kernel optical convolution unit (MOCU) that enables on‐chip parallel convolution processing. By utilizing cascaded silica 1D metalines as pre‐trained large‐scale weights and employing spatial multiplexing at the output, MOCU allows simultaneous passive computation of diverse convolutions within a single unit. This architecture facilitates the construction of optical convolutional neural networks (OCNNs), enabling efficient machine vision processing with a streamlined design. To mitigate errors in MOCU‐embedded OCNNs, a lightweight electronic neural network operates concurrently to calibrate systematic deviations via a low‐rank adaptation (LoRA) algorithm, with minimal overhead. The fabricated MOCU chip demonstrates the highest independent 8‐kernel convolutions in parallel, each with a kernel size and occupying just 0.06 . This architecture effectively merges photonic and electronic technologies, offering a scalable design pathway for energy‐efficient, high‐density deep learning hardware.

Scalable Synaptic Transistor Memory from Solution-Processed Carbon Nanotubes for High-Speed Neuromorphic Data Processing.

Neural networks as a core information processing technology in machine learning and artificial intelligence demand substantial computational resources to deal with the extensive multiply-accumulate operations. Neuromorphic computing is an emergent solution to address this problem, allowing the computation performed in memory arrays in parallel with high efficiencies conforming to the neural networks. Here, scalable synaptic transistor memories are developed from solution-sorted carbon nanotubes. The transistors exhibit a large switching ratio of over 105, a significant memory window of ≈12V arising from charge trapping, and low response delays down to tens of nanoseconds. These device characteristics endow highly stabilized reconfigurable conductance states, successful emulation of synaptic functions, and a high data processing speed. Importantly, the devices exhibit uniform characteristic metrics, e.g., with a 1.8% variation in the memory window, suggesting an industrial-scale manufacturing capability of the fabrication. Using the memories, a hardware convolution kernel is designed and parallel image processing is demonstrated at a speed of 1M bit per second per input channel. Given the efficacy of the convolution kernel, a promising prospect of the memories in implementing neuromorphic computing is envisaged. To explore the potential, large-scale convolution kernels are simulated and high-speed video processing is realized for autonomous driving.

Investigation of Lead, Nickel, and Cadmium Levels in Urine Samples of Healthy and Patients with Kidney Failure in Al-muthanna Governorate, Iraq

Background: The Iraqi ecosystem, particularly in the southern area, has been polluted due to human activity. Analyzing biological materials is the most common method for detecting the presence of toxic substances in the human body. Method: Heavy metal levels of Pb, Ni, and Cd in urine specimens collected from individuals with renal failure and healthy individuals residing in Al-Muthanna province were measured by using atomic absorption spectroscopy. Urine Specimens were collected from two cohorts of male and female participants: the group of individuals with renal failure and the group of individuals who are in good condition. The specimens of urine from both the group of patients with renal failure and the group of healthy individuals were taken from the Al-Muthanna governorate in southern Iraq. This governorate served as a focal point for extensive military operations throughout the Gulf War. Results: The concentrations of toxic substances (Pb, Ni, and Cd) in the urine specimens of the cohort of patients suffering from renal failure are 0.411, 0.197, and 0.113 mg/l, respectively. Concentrations of (Pb, Ni, and Cd) in the healthy group are 0.249, 0.101, and 0.0294 mg/l, respectively. The toxic metals found in urine samples can be organized in the following order: Pb > Ni > Cd. Conclusion: The findings indicated that the concentrations of toxic substances in specimens of urine from individuals with renal failure are considerably greater than those in the control group of healthy individuals. According to the findings, patients' incidence of renal failure may be related to the prevalence of harmful compounds in southern Iraq.

Identification of strategic location for environmental noise control through the application of land use regression (lur) in a neural network platform

The significant causes of rising noise pollution within urban areas lie in extensive transportation networks, industrial operations, and commercial activities. Addressing this complexity, our study employs Land Use Regression (LUR) modelling to assess the intricate relationship between land-use features and environmental noise in urban landscape. The objective of this study is to provide a framework for predicting environmental noise levels in Delhi, India. For which, Lday, Lnight, LAeq, 24h, and Ldn noise descriptors were modelled at daily resolution data from 31 fixed-site monitors. The prediction at first stage for LUR was found to be R2 = 0.53 which was validated using the n-1 method. The model was later optimized using a NN. Output from the NN is included in the GIS environment to identify the hotspot of the noise. Previously identified engineering interventions applicable to urban contexts that were listed from the literature review were allocated as per hotspots because of the modelled output. The study also explored the avenue of using Delhi-specific transport variables developed from Google travel time data for prediction improvement of the noise level. The research contributes to advancement of noise pollution assessment and management methodologies, particularly in situations with no available validated traffic noise models.

Sharp Trace and Korn Inequalities for Differential Operators

AbstractWe establish sharp trace and Korn-type inequalities that involve vectorial differential operators, the focus being on situations where global singular integral estimates are not available. Starting from a novel approach to sharp Besov boundary traces by Riesz potentials and oscillations that equally applies to $$p=1$$ p = 1 , a case difficult to be handled by harmonic analysis techniques, we then classify boundary trace- and Korn-type inequalities. For $$p=1$$ p = 1 and so despite the failure of the Calderón-Zygmund theory, we prove that sharp trace estimates can be systematically reduced to full k-th order gradient estimates. Moreover, for $$1<p<\infty $$ 1 < p < ∞ , where sharp trace estimates yield Korn-type inequalities on smooth domains, we show for the basically optimal class of John domains that Korn-type inequalities persist – even though the reduction to global Calderón-Zygmund estimates by extension operators might not be possible.

A lightweight finger multimodal recognition model based on detail optimization and perceptual compensation embedding

Multimodal biometric recognition technology has attracted the attention of many scholars due to its higher security and stability than single-modal recognition, but its additional parameter quantity and computational cost have brought challenges to the lightweight deployment of the model. In order to meet the needs of a wider range of application scenarios, this paper proposes a lightweight model DPNet using fingerprint and finger vein images for multimodal recognition, which adopts a double-branch lightweight feature extraction structure combining detail optimization and perception compensation. Among them, the detail extraction optimization branch uses multi-scale dimensionality reduction filtering to obtain low-redundant detail information, and combines the depth extension operation to enhance the generalization ability of detail features. The perception compensation branch expands and compensates the model's perceptual field of view through lightweight spatial location query and global information attention. In addition, this paper designs a perceptual feature embedding method to embed perceptual compensation information in the way of importance adjustment to improve the consistency of embedded features. The ABFM fusion module is proposed to carry out multi-level lightweight and deep interactive fusion of the extracted finger modal features from the global to the spatial region, so as to improve the degree and utilization rate of feature fusion. In this paper, the model recognition performance and lightweight advantages are verified on three multimodal datasets. Experimental results show that the proposed model achieves the most advanced lightweight effect and recognition performance in the experimental comparison of all datasets.

The Changing Hydrology of an Irrigated and Dammed Yangtze River: Streamflow, Extremes, and Lake Hydrodynamics

AbstractUnderstanding the role of anthropogenic activities in the hydrological cycle is critical to support sustainable water management for the Yangtze River Basin (YRB), which experiences extensive dam operation, irrigation and water withdrawal. However, this remains challenging due to insufficient accuracies of existing process‐based models for fully depicting anthropogenic activities as part of the hydrological cycle. To this end, this study enhances a national‐scale coupled land surface‐hydrologic‐hydrodynamic model (CLHMS) with a dynamic irrigation scheme for distinct crops, an extended reservoir operation scheme incorporating both water storage anomalies and water demand anomalies, and a cost‐function‐based approach to link water demands with reservoir operation. The enhanced model is extensively validated against historical streamflow, water storage of 90 reservoirs, and irrigation water withdrawal in the YRB, and the water level and storage of the Poyang Lake (PYL). By setting up controlled experiments in the YRB, we show that the streamflow decreases by 2%–6% due to irrigation and water withdrawal, and manifests an attenuated seasonality due to reservoir operation. At the basin scale, the increasing trend of extreme flood peaks exhibits a reversal under human activities, with the flood mitigation effect of irrigation and water withdrawal accounting for up to 50% of that of reservoir operation. The hydrodynamics of the PYL also exhibits considerable human‐induced alterations, with a 1.79 m‐decrease in the water level at the end of flood season. Our study sheds light on quantifying anthropogenic hydrologic impacts at basin scales, with important implications for understanding the co‐evolution between anthropogenic activities and the hydrological cycle.

Superior probabilistic computing using operationally stable probabilistic-bit constructed by manganite nanowire

Abstract Probabilistic computing has emerged as a viable approach to treat optimization problems. To achieve superior computing performance, the key aspect during computation is massive sampling and tuning on the probability states of each probabilistic bit (p-bit), demanding its high stability under extensive operations. Here, we demonstrate a p-bit constructed by manganite nanowire that shows exceptionally high stability. The p-bit contains an electronic domain that fluctuates between metallic (low resistance) and insulating (high resistance) states near its transition temperature. The probability for the two states can be directly controlled by nano-ampere electrical current. Under extensive operations, the standard error of its probability values is less than 1.3%. Simulations show that our operationally stable p-bit plays the key role to achieve correct inference in Bayesian network by strongly suppressing the relative error, displaying the potential for superior computing performance. Our p-bit also serves as high quality random number generator without extra data-processing, beneficial for cryptographic applications.

Postoperative Complications of Upfront Ovarian Cancer Surgery and Their Effects on Chemotherapy Delay.

Extensive surgery on advanced-stage epithelial ovarian cancer is associated with increased postoperative morbidity, which may cause a delay in or omission of chemotherapy. We examined postoperative complications and their effects on adjuvant treatment in patients undergoing primary debulking surgery (PDS). Stage IIIC-IV epithelial ovarian cancer patients who underwent PDS between January 2013 and December 2020 were included. Patients were divided into two groups according to the radicality of the operation, i.e., extensive or standard surgery, and their outcomes were compared. In total, 172 patients were included; 119 underwent extensive surgery, and 53 had standard surgery. Clavien-Dindo grade 3-5 (CDC 3+) complications were detected in 41.2% of patients after extensive operations and in 17% after standard surgery (p = 0.002). The most common CDC 3+ complication was pleural effusion. Despite the difference in the complication rates, the delay in chemotherapy did not differ between the extensive and standard groups (p = 0.98). Complications are common after PDS. Extensive surgery increases the complication rate, but most complications can be treated effectively; therefore, a delay in adjuvant treatment is rare.

Empirical Studies of Russian–Ukrainian War Related Fake News (Part 2)

The Russian–Ukrainian war, which broke out on 24 February 2022, resulted in several paradigm shifts in cyberwarfare. One aspect of these changes is psychological operations. Russia and Ukraine have conducted extensive psychological operations campaigns to fulfil their war aims, which have since been intense along modified objectives. This series of studies examines the impact of war-related fake news through various empirical research. In the first part of the paper, the authors read the emergence of psychological operations and related terms in the international academic literature using network analysis methodology. In the second part of the paper, the authors use sentiment and network analysis to investigate the spread of different fake news. In the third study, the authors measure the attitudes toward the perception of the Hungarian Defence Forces from the perspective of the war in the neighbouring country.

Learning automatic navigation control skills for miniature helical robots from human demonstrations

Magnetic micro-robotic technology holds immense potential for revolutionizing minimally invasive procedures, particularly in the realm of interventional medicine. The ability to effectively and precisely control micro-scale, magnetically actuated robots in real-world scenarios is important. Mastering this capability promises to elevate the precision and efficacy of medical interventions, thereby enhancing patient outcomes. Numerous methods were proposed in previous work and achieved significant progress. However, these efforts primarily focused on model-based strategies and control improvements, with little attention given to the manipulation of the surgeon. This paper presents an exploration of an imitation learning approach, leveraging extensive manual operation experiments, to replicate the task of robotic navigation in simulated vascular environments. The control strategies are directly acquired from experimental observations and encapsulated within a high-dimensional neural network, specifically a tailored variant of the Residual Network (ResNet). The robustness and effectiveness of our proposed methodology are validated through comprehensive experimentation. In automatic navigation trials, the average error spanned from 2.29 mm to 3.32 mm, leading to a mean trajectory deviation of approximately 2.92 mm. The average error rate is 31% lower than that observed in traditional model-based Proportional Integral Derivative (PID) controller (approximately 3.81 mm). In addition, the maximum error (4.87 mm) is 83% of that of the traditional method (5.85 mm). Our findings emphasize the viability and benefits of learning-based techniques in micro-robot control, paving the way for innovative control strategies in interventional surgeries applications.

Investigating the link between the Port of Miami dredging and the onset of the stony coral tissue loss disease epidemics

Since 2014, the stony coral tissue loss disease (SCTLD) has been decimating corals in the Caribbean. Although the trigger of this outbreak remains elusive, evidence suggests waterborne sediment-mediated disease transmission. The outbreak reportedly initiated in September 2014 at a reef site off Virginia Key (VKR), during extensive dredging operations at the Port of Miami. Here we use a high-resolution ocean model to identify the potential driver of the outbreak by simulating the dispersal of dredged sediments, wastewater plumes and disease agents. Our results suggest that VKR could have been impacted by fine sediments produced by dredging operations, especially those involving non-conventional rock-chopping techniques. Wastewater contamination was unlikely. Additionally, our connectivity analysis indicates potential disease transmission from other affected reefs to VKR. Our results therefore suggest that dredging operations might be responsible for the onset of the epidemics. This underscores the need for stricter operational guidelines in future dredging projects.

Long-Term Outcomes of Modified Endoscopic Transcanal Approach to Small Acoustic Tumors.

The management options for small acoustic tumors are still controversial, and surgery is indicated in a select number of patients only. This is to avoid unnecessary extensive operations and risk of complications. Endoscopic transcanal approach, which was recently introduced, can be an alternative option to overcome these challenges. We have developed a modified technique for endoscopic transcanal removal of small acoustic tumors with tympanoplasty using tragal cartilage and without the need to harvest abdominal fat for obliteration. There was also no need to do an ear cul-de-sac procedure compared with the previous method. We report the long-term outcomes of this approach. Retrospective review. Tertiary hospital. Those who were diagnosed with small acoustic tumors between June 2016 and June 2022 were enrolled. Tumor removal via a Modified Endoscopic Transcanal Transpromontorial Approach (mETTA). Tumor control rate, closure rate of tympanic membrane, and complications such as cerebrospinal fluid (CSF) leakage and facial palsy were analyzed. Operation time and hospital stay were also analyzed. Twenty-two patients with a mean age of 55.5 ± 9.4 years were enrolled. Eighteen were vestibular schwannomas (VS), two were intracochlear schwannomas (ICS), and two were with intravestibulocochlear schwannomas (IVCS). Gross total removal was achieved in 21 cases. One had developed significant CSF leakage, and the other patient complicated with permanent facial palsy. The tympanic membrane healed well in all patients, but three patients showed delayed healing until several months and treated conservatively. Mean operation time was 149.6 ± 48.4 minutes, mean hospital stay was 8.9 ± 4.5 days, and mean postoperative follow-up period was 42.0 ± 15.7 months. Long-term results of modified endoscopic transcanal approach to small acoustic tumors are acceptable and comparable to classical treatments such as translabyrinthine approach or gamma knife radiation. This is an alternative option for smaller tumors warranting surgical removal and maintained cosmetic advantages.

Empowering a qudit-based quantum processor by traversing the dual bosonic ladder

High-dimensional quantum information processing has emerged as a promising avenue to transcend hardware limitations and advance the frontiers of quantum technologies. Harnessing the untapped potential of the so-called qudits necessitates the development of quantum protocols beyond the established qubit methodologies. Here, we present a robust, hardware-efficient, and scalable approach for operating multidimensional solid-state systems using Raman-assisted two-photon interactions. We then utilize them to construct extensible multi-qubit operations, realize highly entangled multidimensional states including atomic squeezed states and Schrödinger cat states, and implement programmable entanglement distribution along a qudit array. Our work illuminates the quantum electrodynamics of strongly driven multi-qudit systems and provides the experimental foundation for the future development of high-dimensional quantum applications such as quantum sensing and fault-tolerant quantum computing.

Gastrointestinal stromal tumours: incidence, recurrence and mortality. A decade of patients from a New Zealand tertiary surgical centre.

Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract. The New Zealand (NZ) population incidence has not previously been documented nor has the potential effect of ethnicity been reviewed. We furthermore wanted to assess the difference between those undergoing a wedge resection versus a more extensive operation which we hypothesised would correlate with recurrence and mortality. All patients (n = 103) with a GIST diagnosed and treated at Te Whatu Ora Waitematā (Auckland, New Zealand) between 2012 and 2021 are presented. Patient demographics, method of GIST detection, management approach, index surgery, histological features, use of adjuvant and neoadjuvant imatinib, follow-up, recurrence and mortality rates were analysed. This paper reports the largest NZ GIST cohort to date and estimates an incidence of 17 cases per million per year. Eighty-four patients underwent surgical resection, 58 received a wedge resection and 17 received a more extensive operation. Five-year disease-free survival rates were 100% in the low/very low risk, 90% in the intermediate and 59% in the high risk groups as determined by the modified NIH criteria. Our overall 5-year GIST-specific survival rate was 83%; it was 91% in those who underwent a wedge resection and 60% in the extensive operation group. There is evidence that Māori have higher rates of GIST recurrence compared to non-Māori and are more likely to require an extensive surgical resection.

One Year of Experience in the Orthopaedic and Trauma Surgical Care of War Refugees and Soldiers from Ukraine in a Maximum Care Trauma Centre.

According to the United Nations, around 8,400 people have been injured and over 5,800 killed on the Ukrainian side in the Ukraine war, which has been going on for over 14 months. Extensive humanitarian aid operations were carried out to support Ukraine, so that war-wounded people from Ukraine were also cared for in Germany. In a retrospective cohort study, 10 patients were examined who were treated in the department between February 24th 2022 and February 24th 2023, using the cloverleaf system from Ukraine.The average duration of inpatient treatment was 53.10 days. The average ISS was 23.7. The patients were operated on an average of 3.3 times in our institution. All patients received consultative psychological care. All patients were initially put into protective isolation until the results of a corona test and microbiological swabs were available. After preliminary protective isolation, further isolation had to be carried out in 5 cases due to germs requiring isolation. Eight patients were released to state accommodation. Three patients were transferred back to Ukraine at their own request.The treatment of war-injured patients from Ukraine represents a particular challenge. It absolutely requires an interdisciplinary treatment concept that, in addition to special trauma surgery and orthopaedic expertise, also requires plastic-reconstructive, microbiological and, last but not least, psychological care. Due to the high rate of infections requiring isolation, long, costly therapy with multiple revision operations is often necessary.

Embolization of prostatic arteries to stop bleeding in prostate cancer

Prostatic bleeding is life-threatening, and its most common cause is locally advanced prostate cancer. In several patients, hemostatic therapy is ineffective. Surgery is not feasible in most patients owing to the high surgical risk. In such cases, prostatic artery embolization may be the method of choice to stop the bleeding. This procedure is minimally invasive; thus, it can be performed in patients with contraindications to more extensive operations. Despite limited experience with embolization of prostatic arteries, according to the literature, it is effective in 90% of treated patients. This article provides a review of the literature and clinical observations of the successful use of prostatic artery embolization to stop bleeding in patients with locally advanced prostate cancer.

The Importance of the Use of Unmanned Aerial Vehicles (UAVs) in the Oil and Gas Industry

The oil and gas industry, renowned for its extensive and intricate operations, confronts numerous challenges in maintaining and inspecting its infrastructure. Traditional inspection methodologies, often reliant on manual labor, are not only time-consuming and costly but also expose workers to hazardous conditions. These conventional methods necessitate the shutdown of operations, leading to considerable productivity losses and elevated costs. Over the past decade, the advent of unmanned aerial vehicles (UAVs) has introduced a transformative technology in this sector, providing a safer, more efficient, and cost-effective alternative to traditional inspection techniques. UAVs, equipped with advanced sensors and high-resolution cameras, facilitate detailed visual and thermal inspections of critical assets such as pipelines, flare stacks, and offshore platforms. These capabilities enable companies to perform routine inspections without halting operations, thereby minimizing downtime and operational disruptions. The implementation of UAV technology has notably enhanced safety by reducing the need for human intervention in perilous environments. For instance, the traditional inspection of flare stacks necessitates workers to ascend these structures, posing significant risks. UAVs obviate this requirement by delivering real-time visual data from secure distances. Moreover, the precision and accuracy inherent in UAV inspections contribute to the early detection of defects and potential issues, allowing for prompt maintenance and repairs, which further augment safety and operational efficiency. The environmental benefits of UAV technology are also noteworthy. By diminishing the reliance on heavy machinery and extensive transportation typically associated with inspections and maintenance, UAVs aid in reducing carbon emissions, thus aligning with the industry's sustainability objectives. In summary, the integration of UAVs into the oil and gas industry's inspection protocols represents a significant technological advancement. This integration aligns with the sector's goals of enhancing safety, efficiency, and environmental sustainability, marking a pivotal step forward in the industry's evolution.
