Review of Fault Ride Through Support Schemes and a New Strategy for Low-Inertia Power Systems

A massive deployment of renewable energy sources (RESs) is required to enable the decarbonization of the energy infrastructure. The replacement of conventional generators with inverter-based RESs reduces the rotational inertia and can threaten the frequency stability of the system. This work is motivated by analyzing an actual cascading event in a low-inertia system where a voltage sag event that was cleared within few milliseconds triggers a severe frequency disturbance. During a low voltage sag event, the reactive power is prioritized for voltage support purposes according to the existing low voltage fault ride through (LVFRT) grid regulations, which lead to a significant reduction of active power by RESs that triggers the cascading phenomenon. This event indicates that the existing LVFRT regulations require re-evaluation, especially in low-inertia power systems with increased penetration of RESs. Therefore, the existing grid regulations are thoroughly analyzed with a particular emphasis on the coupling phenomena where a voltage support can threat the frequency stability. Moreover, a new LVFRT strategy is proposed where active power prioritization is introduced for enabling an intense voltage support without causing a significant reduction on active power. The existing and proposed LVFRT schemes are benchmarked considering theoretical and simulation-based analysis indicating that the proposed scheme provides improved support and is adequate for low-inertia power systems with intense RESs penetration.
Bidirectional LSTM Network-Based Short-Term Load Forecasting Method in Smart Grids

Load forecasting, including classic time series analysis and more contemporary machine learning techniques, has emerged as one of the most prominent research domains. The primary emphasis of research in this field lies in predicting aggregated power usage. However, the significance of demand-side energy management, encompassing individual load forecasts, is increasingly gaining prominence. This work proposes load forecasting models that rely on deep neural networks (DNNs). These models are applied to a demand-side load database for analysis. The forecasting accuracy of DNN-based load forecasting models is assessed by comparing them with Convolutional Neural Network (CNN), Long Short-Term Memory (LSTM), and Bidirectional Long-Short-Term Memory (B-LSTM) models. The B-LSTM is a new recurrent artificial neural network recommended as the forecasting unit due to its ability to process information from both the past and present hidden layer using memory loops. Performance of the algorithm is check based on the mean absolute error, mean absolute percentage error, and root mean square error.
A Workflow paper on an effective approach for Face Spoofing Detection Using CNN

-The current facial biometric systems are vulnerable to spoofing attacks. A spoofing attack occurs when someone attempts to impersonate another person and gains unauthorized access by falsifying data. Face-spoofing attacks affect the high-security departments of corporations, government departments, and emerging SMEs. Several face spoofing countermeasures and live detection methods have been proposed, but the problem remains unresolved because of the difficulty in determining the characteristics and methods of spoofing attacks. It was recently shown that traditional facial biometric techniques are more vulnerable to spoofing attacks; therefore, the entire research community has had to focus more on finding solutions to spoofing attacks. The purpose of this study is to detail anti-spoofing methods and database evaluation. This research concludes that it is necessary to provide more general algorithms for detecting unpredictable spoofing attacks to increase system security, computational efficiency, and reliability.

w2---Measuring geophysical parameters of the Greenland ice sheet using airborne radar altimetry

This paper presents radar-altimeter scattering models fi_, each of thc diagenetic zones of the Greenland ice sheet. \. \FE radar-altimeter waxc['orms obtained during lhe 1991 and 1993 muhi-sensor airborne altimetry experiments over Greenland reveal that the Ku-band retm'n pulse changes sip nificantly with the different diagenetic zones. These changes are due to varying amounts of surface and volume scattering in the return wavefi)rm. In the ablation and soaked zones, wherc surface scattering dominates the AAFE return, geoph}sical parameters such as rms surt:ace height and rms sur['ace slope are obtained })y fitting tin' waveforms a surl'ace-scattering model. Wavefi),ms flom the percolation show that sut>sur['ace ice fi'aturcs have a much more significanl effect on the return pulse than the surrosmding srmwpack. Model percolation waveforms, created using a combined surt_,ce-and volume-scattering model and an ice-f'eature distribution obtained during the I993 field season, agree well with actual . \AFE waveforms taken in the same thne period. Using a cornlfined surfi,ce-and volmne- scattering model for the dry-snow-zone return waveforms, the rms sty'face height and slope and the attenuation coefficient _)f the snowpaek are ol)tained. These scattering m()dels not o),ly allow geophysical parameters of the ice sheet to be measured but also help in lhe underslanding of satellite radar-ahimeter data.
Novel and changing social evaluations of all-lowercase and exclamation points

Language is full of variation, which not only patterns along social dimensions but is also socially evaluated by language users (Campbell-Kibler 2007, Labov et al. 2011). However, social judgements are not exclusive to spoken or signed communication. In fact, people also make social evaluations when communicating in the digital space (Houghton, Upadhyay, and Klin 2018; Heath 2021), called computer mediated communication (CMC). This study investigates the social evaluations of two linguistic variables that are exclusive to CMC: capitalization and punctuation. In this study, we compare two capitalization conditions (sentences typed entirely in lowercase, and sentences with standard capitalization at the beginning of a sentence/for proper nouns) and three exclamation conditions (no punctuation, 1, or 2 exclamation points at the end of the sentence).
Phase ii trial of bevacizumab and erlotinib as a second-line therapy for advanced hepatocellular carcinoma

Background: Early clinical studies of bevacizumab and erlotinib in advanced hepatocellular carcinoma (HCC) have a tolerable toxicity and a promising clinical outcome. We evaluated the efficacy and tolerability of this combination as a second-line therapy for HCC refractory to sorafenib. Methods: For this single-arm, Phase II study, we recruited patients with Child–Pugh class A or B liver disease, Eastern Cooperative Oncology Group performance status 0–2, and advanced HCC that was not amenable to surgical or regional therapies and treatment with sorafenib had failed (disease progressed or patient could not tolerate sorafenib). Patients received 10 mg/kg intravenous bevacizumab every 14 days and 150 mg oral erlotinib daily for 28-day cycles until progression. Tumor response was evaluated every two cycles using Response Evaluation Criteria in Solid Tumors. The primary end point was the 16-week progression-free survival rate. Secondary end points included time to progression and overall survival. Results: A total of 44 patients were enrolled and had a median follow-up time of 33.8 months (95% confidence interval [CI]: 23.5 months – not defined). The 16-week progression-free survival rate was 43% (95% CI: 28%–59%), median time to progression was 3.9 months (95% CI: 2.0–8.3 months), and median overall survival duration was 9.9 months (95% CI: 8.3–15.5 months). Grade 3–4 adverse events included fatigue (13%), acne (11%), diarrhea (9%), anemia (7%), and upper gastrointestinal hemorrhage (7%). Conclusion: Bevacizumab plus erlotinib was tolerable and showed a signal of survival benefit in the second-line setting for patients with advanced HCC. Because standard-of-care options are lacking in this setting, further studies to identify predictors of response to this regimen are warranted.
Tree Community Structure and Composition of a One-Hectare Permanent Plot in the Montane Zone of Mount Kerinci, Kerinci Seblat National Park, Jambi

Information on tree community structure and composition is needed in forest management and restoration. These data can be obtained using a permanent plot for studying forest dynamics, including species-specific characteristics. These characteristics are useful in the identification of native species for commercial and restoration purposes. This study aimed to describe the tree community structure and composition of a one-hectare permanent plot in the montane zone of Mount Kerinci. Data collection was conducted from July to August 2016 on Mount Kerinci, Jambi. A plot was established at 2,182-2,258 m above sea level and subdivided into 100 subplots. All trees ≥ 10 cm DBH were tagged and measured. Twenty-eight species, 18 genera, 20 families, 570 individuals and Shannon index 2.89 were identified. Most of the potential species richness was covered on the research site. Syzygium lineatum was the species with the highest importance value and Myrtaceae had the highest family importance level. The study area was dominated by slow growing species that characterize primary forests. The population structure indicated a good capacity of forest regeneration, while the vertical structure formed a stratification consisting of three strata. The dominant large trees and 5 hyperdominant trees according to total biomass contribution were identified. These species are an important priority in forest management and restoration.
Towards an understanding of gender differences with respect to whitewater rafting preferences

Previous literature suggests that there are an increasing number of females participating in outdoor recreation. However, the majority of outdoor programs are still designed under a male dominated paradigm. Few authors have dedicated attention to the special needs of female participants. Furthermore, very little if any attention has been given to the needs of females who assume leadership roles in the community or family and who are responsible for planning and organizing group trips to the outdoors. This lack of attention is contrary to the importance that this market can have for a commercial outdoor recreation outfitter. It is therefore important to determine what type of outdoor experiences interest this market as well as to determine their preferences and the way they establish relationships with their outdoor recreation providers. As both genders are involved in planning outdoor experiences, it is necessary to gain further insight into the differences that exist to enable marketers to create more accurate strategies for attracting clients.
Beyond the Ligand: Extracellular and Transcellular G Protein – Coupled Receptor Complexes in Physiology and Pharmacology Bidirectional

504 Significance Statement. Abstract —— G protein – coupled receptors (GPCRs) activation of the heterotrimeric G protein, thereby inducing the exchange of GDP for GTP on the G a -subunit and the dissociation of G a - from G bg -subunits. Subsequent G a -mediated hydrolysis of GTP to GDP enables the reassociation with G bg to terminate G protein signaling, a process catalyzed by RGS proteins. However, it is now emerging that GPCRs also form a variety of extracellular interactions generalized in the scheme. These complexes are highly diversified and can create junction- or synapse-specific environments to endow GPCR function with specific properties.
Integrating graphical proofs in Coq

We present Actema, a prototype of graphical user interface where formal proofs can be built through gestural actions, and its integration within Coq through the coq-actema plugin. The latter relies on a client-server architecture, where the plugin requests proof steps from the interface, and then compiles them to appropriate tactic calls. To avoid cluttering the proof script with these calls, graphical proofs are stored separately on disk, and recompiled upon execution of the script. This should also allow to “replay” proofs visually in the interface, which is vital for readability and maintenance. The plugin is usable with any Coq IDE, and its design adapted to any goal-directed interactive theorem prover supporting intuitionistic first-order logic.

The Egyptian Cardiothoracic Surgeon

MIMVS could be associated with an increased risk of barotrauma. One lung ventilation elevates inspiratory pressure more than those with normal or low body mass index; venous drainage and arterial line pressure will also be affected [1-3]. On the other hand, obese patients may benefit from MIVS to avoid the risk of sternal wound complications. However, it is controversial which technique has better outcomes regarding the incidence of postoperative bleeding and reexploration [4-6]. Few series exhibited no detrimental outcomes for patients with BMI >30
Electron counting statistics of open quantum systems

Electron transport through organic molecules is a process fundamental to life and plays a central role in the emerging field of molecular electronics. This thesis presents an investigation of electron transport through molecular systems from the perspective of full counting statistics. An extension of a Markovian counting statistics framework to a non-perturbative setting is presented which allows for an exact treatment of the phonon bath. This framework is applied to a theoretical photocell device inspired by the photosystem II reaction centre. It is demonstrated that the asymmetric coupling of excitation and charge transfer states to a structured spectral density rather than a smooth low energy background has the effect of reducing the output current along with an associated reduction in the current fluctuations. The insights gained from this are discussed in terms of design principles for pigmentprotein complexes used in nano-electronic devices and their relevance for biological function in vivo. Finally, the asymmetric coupling of excitation and charge transfer states to their vibrational environment is investigated more closely through the dynamics of a dimer model and the effect of the output current statistics of a prototype photocell.
Microdialysis: Reducing the Delay in Detection of Shift in Molecular Composition a Laboratory Study

Introduction: Microdialysis is one of the methods used clinically for the detection of ischemia. Although microdialysis is reliable, in most clinical settings there is a delay of 1-2 hours before the information is available. Objective: The aim of this study was to evaluate whether an increase in the Microdialysis per fusion rate from 0.3 to 1.0 or 2.0 μl/min was capable of reducing the delay in the detection of a shift in molecular composition. Methods and material: Microdialysis was performed in a container with 3 catheters per fused with 0.3, 1.0 and 2.0 μl/min. The molecular composition in the container regarding glucose and lactate was initially as follows: CGlucose=6.0 mmol/L and CLactate=2 mmol/L. At T=90 min the composition was changed to CGlucose=1 mmol/L and CLactate=12 mmol/L. Dialysates were harvested from the three catheters and were analysed regarding the concentration of glucose and lactate. For calculation of the relative recovery, samples were harvested directly from the liquid. The relative recovery and the delay before new steady state were calculated for each of the 3 catheters. The experiment was performed 8 times. Results: A decrease in relative recovery was found with the higher perfusion rate. For glucose, the relative recovery was 100, 88, and 69% at perfusion rates of 0.3, 1.0 and 2.0 μl/min. For lactate, the corresponding values were 103, 93, and 77%. An increase in the lactate/glucose ratio was found with the higher perfusion rate. The delays in detection of shift in molecular concentration were found to be 60, 20, and 10 minutes for catheters 0.3, 1.0 and 2.0, respectively. Conclusion: Using microdialysis it is possible to significantly reduce the delay while still detecting a shift in the concentration of glucose and lactate when the perfusionrate is increased.
The role of insulin glulisine to improve glycemic control in children with diabetes mellitus

: Glulisine (Apidra ® ) is a rapid-acting human insulin analog approved for use in children with diabetes mellitus $ 4 years of age. Management of children with type 1 diabetes has seen a shift in favor of mimicking normal physiological insulin responses with multiple daily injections or continuous subcutaneous insulin infusions (CSII). Few studies have compared the rapid-acting insulin analogs in this population but limited data indicate that glulisine is as effective as lispro when used in a basal–bolus regimen. This review appraises the current available studies and reviews on insulin glulisine in children. An extensive keyword search of ‘insulin glulisine’, ‘insulin analogs’, and ‘Apidra’ in the pediatric population was performed. These studies have suggested that glulisine is safe, well tolerated, and is an effective option in the diabetes armamentarium. Further studies are needed to determine its safety for use in CSII pumps in the pediatric population.
Political Corruption: Readings in Comparative Analysis

Corruption is once again high on the international policy agenda as a result of globalization, the spread of democracy, and major scandals and reform initiatives. But the concept itself has been a focus for social scientists for many years, and new findings and data take on richer meanings when viewed in the context of long-term developments and enduring conceptual debates. This compendium, a much-enriched version of a work that has been a standard reference in the field since 1970, offers concepts, cases, and fresh evidence for comparative analysis. Building on a nucleus of classic studies laying out the nature and development of the concept of corruption, the book also incorporates recent work on economic, cultural, and linguistic dimensions of the problem, as well as critical analyses of several approaches to reform. While many authors are political scientists, work by historians, economists, and sociologists are strongly represented. Two-thirds of the nearly fifty articles are based either on studies especially written or translated for this volume, or on selected journal literature published in the 1990s. The tendency to treat corruption as merely a synonym for bribery is illuminated by analyses of the diverse terminology and linguistic techniques that help distinguish corruption problems in the major languages. Recent attempts to measure corruption, and to analyze its causes and effects quantitatively are also critically examined. New contributions emphasize especially: corruption phenomena in Asia and Africa; contrasts among region and regime types; comparing U.S. state corruption incidence; European Party finance and corruption; assessments of international corruption rating project; analyses of international corruption control treaties; unintended consequences of anti-corruption efforts. Cumulatively, the book combines description richness, analytical thrust, conceptual awareness, and contextual articulation.
Measurement of 87Rb Rydberg-state hyperfine splitting in a room-temperature vapor cell of 87Rb Rydberg-state hyperfine splitting in a room-temperature vapor cell.

We present direct measurements of the hyperﬁne splitting of Rydberg states in 87 Rb using electromagnetically induced transparency (EIT) spectroscopy in a room-temperature vapor cell. With this method, and in spite of Doppler broadening, linewidths of 3.7 MHz FWHM, i.e., signiﬁcantly below the intermediate-state natural linewidth, are reached. This allows resolving hyperﬁne splittings for Rydberg s states with n = 20 ,. , 24. With this method we are able to determine Rydberg state hyperﬁne splittings with an accuracy of approximately 100 kHz. Ultimately, our method allows accuracies of order 5 kHz to be reached. Furthermore, we present a direct measurement of hyperﬁne-resolved Rydberg-state Stark shifts. These results will be of great value for future experiments relying on excellent knowledge of Rydberg-state energies and polarizabilities.
Efficacy of Dietary Supplementation with Phytase and Citric Acid on Whole-Body Composition and Hematological Parameters of Cyprinus carpio and Cirrhinus mrigala Fingerlings Fed on Canola Meal-Based Diet

A 90-day feeding trial was designated to evaluate how canola meal (CM)-based diet supplemented with phytase (PHY) and citric acid (CA) affects whole-body composition and hematological parameters in Cirrhinus mrigala and Cyprinus carpio fingerlings. Sixteen experimental diets (T 1 ─T 16 ) with varied CA (0 and 2.5%) and PHY (0 and 750 FTU/kg) levels were prepared. The fingerlings were fed at the rate of 5.0% of live fish body mass. Fifteen fish were randomly stocked into triplicate tanks for each of sixteen test diets. Significant ( p <0.05) increase in crude protein (CP) and crude fat (CF) was noticed in fish fed T 12 (2.5% CA and 750 FTU/kg PHY) diets. Comparison of treatments showed maximum values of RBCs (3.57×106 mm -3 and 3.18×106 mm -3 ), PLT (83.32 and 80.35), Hb (8.92g/100ml and 8.62g/100ml) and PCV (29.07% and 30.07%) in C. mrigala and C. carpio fingerlings, respectively, when fed with T 12 diets. Conclusively, a 50% CM-based diet with 2.5% CA and 750 FTU/kg PHY supplementation, performed better in terms of whole-body composition and hematological parameters in C. mrigala and C. carpio fingerlings.
