SEM image contour extraction with deep learning method

The contour data extracted from SEM wafer images after the lithography are widely used in the critical dimension (CD), edge placement error (EPE) measurement. It is important to obtain the contours fast and accurate before the analysis of lithographic process and calibration of the lithographic models. Without the accurate contour data, the complete CDU, PVband analysis and inverse lithography technique are hard to realize. With the continuous shrink of the technology nodes, the demand for the accurate contour extraction increases. However, fast and accurate contour extraction from SEM images with defects and noises is challenging. We apply the U-Net to the semantic segmentation of SEM images. The contour extraction and evaluation can be done better after the image segmentation. Our experimental results show that satisfactory contour data of various types of lithographic patterns can be obtained with noisy SEM images.
Fabrication and physicochemical characterization of copper oxide–pyrrhotite nanocomposites for the cytotoxic effects on HepG2 cells and the mechanism

Abstract Novel CuO–FeS nanocomposites were synthesized to exert anticancer effects on HepG2 cells. The formation was initially demonstrated using UV–Visible spectrophotometry analysis, which indicated two peaks at 335 and 370 nm. Characteristic Fourier transform infrared spectroscopy peaks for Cu–O and Fe–S bonds were observed at 516, 577 and 619 cm−1 in addition to other notable peaks. The Miller indices correspond to the lattice spacing of monoclinic CuO and FeS as observed by selected area diffraction rings concurrent with the X-ray diffraction observations. The morphology was interpreted by scanning electron microscopy and transmission electron microscopy, indicating a particle size of 110 nm. As per energy-dispersive X-ray spectroscopy analysis, strong peaks for Cu (0.9, 8 and 9 keV), Fe (6–7 keV), O (0.5 keV) and S (2.5 keV) indicated the formation of CuO–FeS blend with no impurities. A mean particle size of 121.9 nm and polydispersity index of 0.150 were displayed by dynamic light scattering analysis and the zeta potential was −29.2 mV. The composites were not toxic to normal 3T3-L1 cells and were not haemolytic even at higher doses. In addition, the stable composites exerted cytotoxic effects on HepG2 cells (IC50 = 250 ± 5.7 μg/mL) and induced cell death by creating a loss in mitochondrial membrane potential and induction of mitochondrial apoptosis in a ROS-independent manner.
Security in vehicular ad hoc networks

In the last few years, Vehicular ad hoc Networks (VANETs) have attracted a lot of attention and have triggered the development of many new attractive applications. They have become a fundamental component of many intelligent transportation systems and VANETs are being used to improve road safety and enable a wide variety of value-added services. Nevertheless, VANET applications have stringent security requirements because they affect road traffic safety. Several security threats and different types of attacks against VANETs have emerged recently that attempt to compromise the security of such networks. These attacks can cause catastrophic results such as the loss of lives or the loss of revenue for those value-added services. Therefore, making VANETs secure has become a key objective for VANET designers. Since traditional security mechanisms are not always suitable to some unique features in VANETs (e.g., high mobility of nodes), industry and academia have been focusing on improving VANET security. We present threats and attacks that can be launched on VANETs and we identify the security solutions to mitigate them. We also highlight VANET security challenges that still need to be addressed to enable robust, scalable, cost-effective secure solutions for VANETs.
Accelerated multiphase water transformation in global mountain regions since 1990

Mountains are sensitive to climate change, and while amplified warming at high elevations is widely observed and fairly well understood, changes in the water cycles of mountain regions remain poorly quantified. Due to low temperatures at higher elevations, these changes involve multiphase water transformation (MWT). Through analyzing extensive data from global mountain regions, we determined that under the accelerating warming and lengthening ablation period since the 1990s, the strengthening solid�Cliquid transformation can be confirmed for 45 glacier basins or single glaciers. This is marked by an increase of 21.5 km2/10a in glacier area retreat rate, 387.65 mm for average negative glacier mass balance, and 60 m/10a for average glacier length retreat rate (of 414 glaciers) from the study period before the 1990s until the period after the 1990s. The accelerating liquid�Csolid transformation was indicated by an increase of 31.2 d/10a for the delaying trend of complete freeze time, an increase of 4.3 d/10a for the advancing trend of complete melting time, and an increase of 3.9 d/10a for the decreasing trend of ice cover duration for 22 lakes from the period before the 1990s until the period after the 1990s. The accelerating liquid�Cgas transformation can be confirmed by an increase of 1 and 0.69 mm/d/10a in the variation trend of actual evaporation and bare-soil evaporation from 1980�C1990 to 1990�C2017, respectively. Snow sublimation decreased by 0.69 mm/d/10a during 1980�C1990, followed by a statistically significant increase of 1.66 mm/d/10a during 1990�C2017, further confirming the accelerating solid�Cgas transformation. The accelerating gas�Csolid transformation can be reflected by an increase of 0.3 d/10a for the decreasing trend of frost days from 1960�C1990 to 1990�C2017. The moisture recycling ratio decreased by �C0.042 %/10a during 1980�C1990 and then increased by 0.443 %/10a during 1990�C2017, with the corresponding average values of 12.3% and 13.6%, respectively, which indicates an accelerating gas�Cliquid transformation. Approximately 59 rivers displayed an increase of 108.60 m3/s/10a for the runoff variation trend from the period before the 1990s until the period after the 1990s. In addition, the trends for lake number and lake area in the Tibetan Plateau increased 3.86 and 5.75 times, respectively, from 1976�C1995 to 1995�C2019. This acceleration can significantly change the spatiotemporal pattern of water resources and increase the frequency and intensity of disaster events, such as glacial lake outbursts, flooding, and waterlogging. Consequently, most mountain regions will require strong adaptation efforts to sustain water, food, and ecological security.
Correlation of Lumbar Spine Fat Thickness and Surgical Site Infection in Degenerative Lumbar Spine Surgery

Introduction: Surgical site infection (SSI) is a serious and common complication following any surgery. Patientsundergoing lumbar surgery have a higher risk for SSI. Therefore, it is essential to accurately identifythe risk factors of SSIs to prevent them. There is an insufficient number of studies internationally andonly one to our knowledge nationally that studied the correlation between lumbar fat thickness andSSI in patients undergoing lumbar spine surgery. Our aim was to identify the correlation betweenlumbar fat thickness and SSI and determine its predictive value compared to other risk factors inpredicting the incidence of SSI. Methods: This retrospective cohort study involved all patients aged 18 and above who underwent primary elective degenerative lumbar spine surgery in National Guard Health Affairs (NGHA) from 2016 to 2020 at King Abdulaziz Medical City (KAMC), Riyadh, Saudi Arabia. All trauma and oncology cases, patients with previous spine surgery, non-instrumented cases, and emergency cases without preoperative radiological images were excluded. The pre-operative and post-operative measurements were assessed using the sagittal MRI images on the T1 view to measure the fat length of the lumbar spine from L2 to S1. Two observers evaluated the films, and the average measurement was documented for each level. Results: 151 patients were included in our study, four of whom developed SSI. When comparing the demographics of both groups, BMI was found to be a significant variable between both groups, with a P-value of 0.013. However, there was no significance regarding age, gender, DM, HTN, steroid use, and level of stay for each group. Furthermore, there was no significance in all vertebrae levels except for L4 fat thickness, which was significantly higher in the SSI group with a P value of 0.0264. Conclusion: Surgical site infection (SSI) is a serious and common complication following any surgical operation. Patients undergoing lumbar surgery have a higher risk for SSI. In this study, we concluded that an increased L4 fat thickness was a significant predictor of SSI.

PRODUCTIVE RESPONSE OF LACTATING DUAL-PURPOSE COWS GRAZING IN AN AGROSILVOPASTORAL SYSTEM DURING THE DRY SEASON SUPPLEMENTED WITH LOW LEVELS OF CRUDE PROTEIN

Background. Cattle production in tropical regions of Mexico is in dual-purpose farms (DP) on unintended agrosilvopastoral systems (ASPS) with pastures dominated by tropical grasses with scattered shrubs and trees. During the dry season due to the forage diminished nutritional value and availability most farmers supplement their cattle to sustain milk production and weight gains of calves, without taking into consideration the wide variety of forages available in grazing lands to decide the composition of supplements offered to their cattle. Objective/hypothesis. The objective of the study was to determine the effect of low levels of crude protein (CP) content in supplements (S10 = 100, S11 = 110 and S12 = 120 g CP/kg of DM) on the performance of lactating Brown Swiss (BS) cows on an ASPS during the dry season. We hypothesize that low levels of CP in supplements of lactating grazing cows on an agrosilvopastoral system during the dry season would not affect animal performance. Methodology. The study was carried out in the dry season (March to June of 2012), in a commercial DP in the State of Mexico. Eighteen multiparous BS cows and their calves were used in the study, randomly allocated to three groups (six cows/group), to receive one of three supplements (4.5 kg DM/cow/day), consisting of 100, 110 or 120 g/kg DM of crude protein (CP) S10, S11 and S12, respectively. Data were analysed as a complete random experimental design with a mixed model. Results. There were no significant differences in most of the animal performance variables (P > 0.05), except for fat protein corrected milk (FPCM) where S12 (6.4) was significantly higher than S10 and S11 (4.7 and 4.5 kg/day, respectively). Milk protein yields (kg/day) significantly increased as the CP level increased in supplements. High levels of milk urea nitrogen (MUN) were detected (mean 14.0 mg/dL). Implications. In similar DP farms where cattle have access to other sources of forages like shrubs and trees, it is possible to reduce the CP content of supplements and to increase the efficiency of utilization of those alternative forages as well as a reduction in supplementation costs. Conclusion. There were no significant differences in the performance of BS cows grazing on an ASPS during the dry season receiving supplements with low crude protein levels. When correcting to fat-protein milk yields a significant difference was found in favour of supplement with 120 g CP/kg of DM.
Separation of ISS Seismic Data via Vector Median Filter in T-X and F-X Domains

The ISS (independent simultaneous sweeping) vibroseis seismic data acquisition method (Howe, D. et al., 2008) allows multiple vibrator fleets sweeping independently and simultaneously in different vibration points. It compresses acquired seismic data size and increases productivity significantly. However, during ISS vibroseis seismic acquisition the seismic waves from simultaneous sweeping vibrator points interfered with each other and it is necessary to deblend, or to separate the blended seismic data. This paper gives a brief introduction for ISS, and methods for deblend seismic waves.
Recognizing explosion sites without seismogram readings: neural network analysis of envelope-transformed multistation SP recordings 3–6 Hz

SUMMARY Seismic-waveform similarities for closely spaced earthquakes and explosions in particular are well established observationally. In many industrialized countries of low seismicity more than 90 per cent of seismic event recordings stem from chemical explosions and thus contribute significantly to the daily analyst workload. In this study we explore the possibility of using envelope waveforms from ap rioriknown explosion sites (learning) for recognizing subsequent explosions from the same site excluding any analyst interference. To ensure high signal correlation while retaining good SNRs we used envelopetransformed waveforms, including both the P and Lg arrivals. To ensure good spatial resolution we used multistation (network) recordings. The interpolation and approximation neural network (IANN) of Winston (1993) was used for teaching the computer to recognize new explosion recordings from a specific site using detector output event files of waveforms only. The IANN output is a single number between 0 and 1, and on this scale an acceptance threshold of 0.4 proved appropriate. We obtained 100 per cent correct decisions between two sets of ‘site explosions’ and hundreds of ‘non-site’ explosions/earthquakes using data files from the Norwegian Seismograph Network.
Lithological controls on soil properties, Snow Island, Maritime Antarctica

Soil–parent material is a critical controlling factor of soil properties in the Antarctic region due to a limited degree of soil development. However, the degree to which soil–parent material can be considered the major controlling factor in pedogenesis and subsequent soil physical and chemical properties in Antarctica should be better understood to improve soil mapping and interpretations. The present study aims to analyze the soil properties of different lithological groups on the President Head Peninsula on Snow Island, Maritime Antarctica. Thirty soil profiles across the major lithological groupings on Snow Island (beach deposits, andesites, basalts/andesites, conglomerate, sandstones, siltstones, and mudstones) were described, and the morphological, physical, and chemical properties of samples from sampled genetic horizons were characterized. Beach deposits were most clearly differentiated from other lithological groups, whereas most other groups overlapped strongly in observed properties. Whereas some lithological groups (e.g., sedimentary rock groups) were characterized largely by immature soils with little degree of pedogenesis, other sampled soils exhibited more development. The soil–parent material relationships of Snow Island revealed a unique setting of a complex heterogeneous landscape and show that the area has a great pedological complexity induced by phosphatization, melanization, and cryoturbation processes that preclude placing primary importance on parent material and lithology as the major controlling factor in Antarctic soils.
PACT-UK (PAncreatic Cancer reporting Template–UK): a cross-specialty multi-institutional consensus panel development of a standardised radiological reporting proforma for pancreatic cancer

Appropriate staging of pancreatic cancer is essential to ensure patients are offered all treatment options. This multispecialty national collaborative consensus project aimed to develop a succinct radiological reporting template, using the concept of structured reporting, to allow a more standardised means of reporting pancreatic cancer and ultimately optimise both patient care and research protocol design.In stage one, a core group of stakeholders (oncologists, radiologists and surgeons) identified the current landscape of radiological reporting, including a blinded radiological validation study and a national survey of consultant HPB surgeons. Stage two used consensus panel development methodology to generate a provisional template draft. Stage three involved trialling the template across all UK HPB units, with feedback assisting the development of a final version of the template.Stage one results identified a core dataset to develop a provisional template. Every UK Hepatopancreatobiliary (HPB) unit trialled this in clinical practice, leading to further refinements via consensus meetings. Ideal factors regarding tumour staging, extent of vascular involvement and response to systemic anticancer therapy were identified. This resulted in the generation of the PACT-UK (PAncreatic Cancer reporting Template–UK) template that is presented within the manuscript, as well as a user guide.This project has successfully produced the first consensus-driven radiological reporting template for pancreatic cancer, with the aim of its use becoming standard practice in the UK, while upcoming workshops facilitated by Royal College of Radiologists/British Society of Gastrointestinal and Abdominal Radiology will establish buy-in from radiologists at all HPB units. Plans for the use of PACT-UK within national audit and clinical trials are underway.

A new species of Orchomenella (Amphipoda, Tryphosidae) described from hydrothermal vent in the Okinawa Trough, Northwest Pacific

﻿Abstract A new species of the family Tryphosidae, Orchomenellacompressasp. nov., is described from hydrothermal vents in the Okinawa Trough. This is the first known Orchomenella species found in vent fields. Important morphological characters that differentiate O.compressasp. nov. from its congeners are the absence of eyes, the compressed distal three articles of gnathopod 2, the shape of the posterior margin of epimerons 2 and 3, and the number of dorsal spines on the telson. The genetic divergence of the analyzed COI gene clearly supports this new taxon.
