In this work, we investigate various types of ionospheric disturbances
observed over Europe after the earthquake in Turkey on 6 February
2023.By combining observations from Doppler sounding systems,
ionosondes, and GNSS receivers, we are able to discern different types
of disturbances, propagating with different velocities and through
different mechanisms. We can detect the co-seismic disturbances produced
in the ionosphere close to the epicenter, as well the ionospheric
signatures of acoustic waves propagating as a consequence of propagating
seismic waves.
A Generalization of the Burridge and Knopoff Model
Authors: NETCHEV PLAMEN NEYTCHEV , Garzón Ricardo Ceballos , Bermudez Mauricio Alberto
Published: May 2023

The paper is dedicated to the classical glissade’s modeling in order to
explain the earthquake mechanisms. The B&K model has been rethought
generalizing the uniform movement of the largest stratum, corresponds to
any continually acting force. In addition, for the resistance function
has been used an expression obtained by the authors, based on the
Elementary Catastrophes Theory that fully satisfies the conditions of
the existence and uniqueness theorem regarding the solutions of the
systems of ODE. The generalized B&K model equations have been solved
numerically for a particular case through the respective standard
software package MATLAB. The analysis of the results highlights a
periodicity at the seismic activity (obtained at constant force) and the
earthquake’s appearances it is shown as a consequence of the different
system’s resonance points. All of the above would allow through the
reengineering methods obtaining valuable information related to the
structure and behavior of local plates.

Published: May 2023

On 12 October 2020 and 26 December 2021, NASA’s Global-scale
Observations of the Limb and Disk (GOLD) mission observed differently
shaped EPBs simultaneously within ~10o longitude, near
the subsatellite point and over the Atlantic, respectively which is
unusual. On 12 October 2020, three EPBs with differing curvatures were
observed in a ~12o longitude sector. The westside EPB
was curved towards the east, in a C-shape. The middle was straight. The
eastside EPB was curved westward, in a reversed C-shape. In the second
case, 26 December 2021, in a smaller longitude range of
~6o adjacent C-shaped and reversed C-shaped EPBs were
observed. EPBs’ zonal drift velocities at the magnetic equator and both
EIA crests were compared. These occurrences of oppositely shaped EPBs
simultaneously in a narrow longitude may indicate that small-scale
longitudinal variations in the E-region density, electric field, neutral
wind variations, or a combination of them were present.
Improving the stability of a probiotic product with Lactiplantibacillus plantarum 299v by introducing flow pack bags

Published: May 2023

Probiotic products are becoming more common in everyday use around the world, while at the same time, the interest of scientists in researching probiotic production and use is increasing. Stability of a probiotic product in pharmaceutical production is affected by the choice of probiotic strain, formulation, and packaging. Packaging is the final stage of production and presents a crucial factor for the stability of probiotic products to maintain declared probiotic viability during the products' shelf life. The present research describes the influence of additional packaging material on the encapsulated probiotic product, which contains Lactiplantibacillus plantarum 299v. In specific, the effect of additional blister protection within flow pack bags was investigated. Blisters were made of a chloride/poly-vinylidene chloride/polyethylene-triplex foil (PVC/PVdC/PE foil) and aluminum foil. Viability of probiotic lactobacilli cells protected in blisters only was compared to those packed in flow pack bags filled with nitrogen as an inert gas. Better protection of probiotic cells from oxygen, light, and moisture was determined in the capsules in the latter case. In specific, introduction of additional blister protection in flow pack bags resulted in ~11 % higher probiotic viability when compared to the other blister samples without such protection after 24 months, and therefore it enabled more efficient storage of the product during use.
Good-Bye I/B/E/S (or Not?)
Authors: Law Kelvin K. F.
Published: May 2023

In October 2018, I/B/E/S claimed to have anonymized the identifications (IDs) of 88 brokers and their analysts in its Detail History Files. This paper examines to what extent the change affects the post-2018 Detail History File. The main findings are as follows. First, there is no evidence of a large-scale ID anonymization for the annual and quarterly EPS forecasts for U.S. firms. Second, the anonymization predominantly affects the forecasts of non-U.S. firms. A significant percentage of forecasts for non-U.S. firms have been anonymized since January 2017 (at least one year earlier than what was claimed). Third, there is no evidence of a large-scale ID reshuffling of forecasts between the 2015 and 2021 Detail History Files. Last, because the anonymization has very little effect on the Recommendations Detail File, I am able to offer detailed steps to reverse engineer the anonymized analyst IDs in the Unadjusted Detail History File.

Authors: Marwaa Mille Nabsen , Klakk Egebæk Heidi , Dalgaard Guldager Julie
Published: May 2023

Objective: To identify and describe occupational and physiotherapy rehabilitation modalities used to support an interdisciplinary rehabilitation in adults (aged 16 + years) with concussion.Methods: A scoping review methodology was used. Included studies were categorized according to Wade’s elements of rehabilitation and the Danish White Paper definition of rehabilitation.Results: Ten studies were included in this review, addressing: “assessment” (n = 9), “goal-setting” (n = 4), “training” (n = 10), and “social participation and discharge support” (n = 4). Interventions were delivered mainly by physiotherapists or an interdisciplinary team. In two studies occupational therapists were part of the interdisciplinary team. Randomized controlled trials more often addressed several of the rehabilitation elements using interdisciplinary intervention delivery. No studies specifically aimed their intervention at patients with acute or subacute concussion.Conclusion: The therapeutic modalities identified were: (i) manual and sensory motor interventions; (ii) physical exercises; and (iii) management of, or coping with, symptoms. More research is needed on how to better support social participation and discharge or return to work in the rehabilitation process. In addition, interventions delivered in the acute phases of concussion need further exploration.LAY ABSTRACTIndividuals with prolonged or persisting symptoms from a concussion often struggle to participate in activities of daily living, and their quality of life and work ability is affected. Interdisciplinary rehabilitation is recommended, and it is recognized that occupational and physiotherapy is important to support the interdisciplinary rehabilitation and promote recovery. However, this scoping review found that occupational therapists were seldom part of the interdisciplinary rehabilitation team. Furthermore, the physiotherapy and occupational rehabilitation modalities used consisted of manual or sensory motor interventions, physical exercise interventions, and management and coping. Only a few studies included social participation and discharge support as a part of the rehabilitation. No studies specifically aimed their intervention at preventing prolonged symptoms in patients with acute or subacute concussion. There is a need for more research into how to better support social participation and discharge in the rehabilitation process. Also, interventions delivered in the acute phases of concussion need further exploration.
Long-standing Complex Regional Pain Syndrome-type I: Perspectives of Patients Not Amputated
Authors: Domerchie Patrick N. , Dijkstra Pieter U. , Geertzen Jan H.B.
Published: May 2023

Objective: Complex Regional Pain Syndrome type I (CRPS-I) is an often intractable regional pain syndrome, usually affecting limbs in which amputation may be a final resort. Not all patients are suited for amputation. This retrospective case series with explorative interviews aims to gain insight in the quality of life in those who have been denied an amputation and their functioning with CRPS-I.Patients and methods: Between 2011 and 2017, 37 patients were denied an amputation. Participants were interviewed regarding quality of life, treatments received since their outpatient clinic visit and their experiences at our outpatient clinic. Results: A total of 13 patients participated. Most patients reported improvements in pain, mobility and overall situation. All patients received treatments after being denied an amputation, with some reporting good results. Many felt they had no part in decision making. Of the 13 participants 9 still had an amputation wish. Our participants scored worse in numerous aspects of their lives compared with patients with an amputation from a previous CRPS-I study of us.Conclusion: This study shows that amputation should only be considered after all treatments have been tried and failed, since most participants reported improvements in aspects of their functioning over time.
LAY ABSTRACTPeople with complex regional pain syndrome suffer from severe pains, usually in a limb, which can lead to serious and longstanding disability. Sometimes when all other treatments have been tried, amputation is the only option left. Not all patients are suitable for amputation. This study tries to gain insight into those patients who have been denied an amputation. Our findings show that over time most patients reported improvements in pain, mobility and overall situation. All patients received further treatments after being denied amputation. Our study showed that amputation should only be considered after all other treatments have been tried and have failed, since over time, most of our participants still reported improvements in various aspects of their functioning.
Understanding the fluxes of greenhouse gases in reservoirs under the inspiration of Margalef
Authors: León-Palmero Elizabeth
Published: May 2023

Reservoirs are significant sources of greenhouse gases (GHG), such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), to the atmosphere. These systems receive and metabolize a larger amount of organic and inorganic carbon and nitrogen from their watersheds than lakes, resulting in the production of CO2, CH4 and N2O. Despite their global relevance, there are still important uncertainties regarding the magnitude, variability and drivers of their emissions that undermine global estimates. Therefore, a comprehensive understanding of the origin of these emissions is required. Here, I investigate the fluxes of CO2, CH4 and N2O and their concentrations in the water column of twelve Mediterranean reservoirs during the stratification and mixing periods to discern the main pathways involved in their production and the spatial and seasonal variability among these gases and their emissions and radiative forcing. Finally, I provide a theorical framework to understand GHG emissions as a response of reservoirs to eutrophication and external forcing. I integrate Margalef’s ideas about how eutrophication perturbs the biogeochemistry of inland waters with the main findings of my previous work to analyze how the C, N and P inputs from reservoir watersheds modify the biogeochemical cycling of C, N, P and O, and determine the production and emission of CO2, CH4, and N2O. This perturbation effect is especially notable for CH4, and N2O emissions, which increase significantly in eutrophic waters, even exceeding the climate forcing of CO2. Therefore, emission of GHG should be seen as part of the reservoir response to the external forcing that displaces a fraction of the materials to the atmospheric boundary.

Authors: Gale Andrew Scott
Published: May 2023

New material of Roveacrinidae from the middle–upper Cenomanian Grey Chalk Group of the Kent coast (Folkestone-Dover) is described. The fauna includes 10 taxa, including a new genus and species ( Dubrisicrinus minutus) and three new species ( Styracocrinus shakespearensis, Roveacrinus aboudaensis and Dentatocrinus serratus). The biostratigraphical significance of roveacrinid faunas is placed in a global context, and it is demonstrated that the roveacrinid zone CeR5, previously recorded only from Morocco, is approximately equivalent to the upper middle Cenomanian Acanthoceras jukesbrownei ammonite Zone, and zone CeR6 – to the Calycoceras guerangeri ammonite Zone. The new material also provides novel information on the cup structure of roveacrinids, which is reviewed and placed in a phylogenetic context.

Published: May 2023

In order to solve the problem that the initial center of traditional clustering algorithm is easy to fall into local optimum and time-consuming. An improved combination optimization algorithm of principal component analysis and weighted K-means clustering is proposed. The algorithm introduces the maximum and minimum distance, weighted Euclidean distance, starting from the mean sum of the distances of the remaining clustering points, avoiding the influence of outliers and edge data. The proportion method is used to improve the principal component, and the characteristic influence factor obtained is used as the initial characteristic weight to construct a weighted Euclidean distance metric. According to the influence factors of feature contribution rate on clustering, a clustering method of feature weight influence factors is proposed. The representative feature factors are selected to highlight the clustering effect. Finally, the driving cycle of automobile is synthesized and the instantaneous fuel consumption is analyzed. The results show that: the difference value of speed acceleration joint distribution of the proposed method is only 1.05%, which saves 44.2% of the time compared with the traditional K-means clustering, and the driving cycle fitting degree is high, which can reflect the actual vehicle operation characteristics and fuel consumption.

Published: May 2023

In recent years, COVID-19 has swept the world, and people in crowded public places are usually large. In order to reduce the risk of virus transmission, stop the spread of the epidemic and reduce cross-infection, wearing masks correctly has become an important measure to prevent the virus. Aiming at the time-consuming and laborious situation of wearing masks manually, this paper proposes a mask wearing detection method based on yolov5. The input layer is mainly used for mosaic data enhancement, that is, adaptive anchor box and adaptive image scaling technology; Yolov5 in backbone mainly adopts focus and CSP (cross stage partial) structure; The neck layer adopts spp (spatial pyramid pooling) module and FPN (feature pyramid networks) + pan (pixel aggregation network) structure; The output mainly adopts ciou for the bounding box loss function_Loss is the average index of NMS (non maximum suppression). This method uses 8000 preprocessed images as the data set and trains 200 epochs to get the final model. The algorithm visually displays the training and test results through tensor board, and inputs the pictures captured by the camera into the model to detect whether the face wears a mask. The accuracy, recall and mean accuracy (map) of the algorithm on the test set are 94.8%, 89.0% and 93.5% respectively, which are higher than the detection results of yolov3 and yolov4 algorithms.

Published: May 2023

The variable fatigue loading (VL) is an important issue for aircraft safety. Indeed, aluminium alloy parts are always the subject of this type of thermo-mechanical alterations. This study examined the effect (VL) under normal operating conditions. We investigated the effect of fatigue variable loading (VL) under combined high temperature (HT) and shot peening (SP) treatment for (AA2024-T4 and AA2024-T361). Fatigue under loading from 250 to 350MPa with various combinations of loading cycles is presented.

The experimental fatigue life results were compared to Miner’s rule. The comparison shows that the fatigue life of tested specimens during the low to high stress sequences is higher than that of the (high to low) ones. This highlights the beneficial effect of (SP) which made the fatigue life predicted by Miner rule safe but not economical. We conclude that considered alloys under SP improves the variable fatigue life under 250°C. In fact, taking into account the interaction effects of loading sequences, those due to high temperature and surface treatment such as (SP) is very important for fatigue prediction based on such alloys.

Published: May 2023

The article proposes a new technique for estimating the instantaneous supply in gear hydraulic machines. It takes into account the peculiarity of the movement of the radius connecting the centers of rotation of the gears with the point of engagement. The dependence of the angular velocity of rotation and the length of the radius on the position of the engagement point due to slipping of the working profiles of the gear teeth are determined. Estimation of the degree of non-uniformity of the supply, in accordance with the obtained model, differs significantly from the traditional ideas about the pulsation of the instantaneous supply in gear hydraulic machines.

Gender, Judging and the Courts in Africa has been professionally edited by Jarpa J. Dawuni. The volume starts with acknowledgments, a list of abbreviations, notes by the Chief Justice of Tanzania and a foreword. The foreword is particularly interesting. In it, Senior Vice President and General Counsel for the World Bank Group, Sandie Okoro highlights the benefits of gender-smart development policies in enhancing productivity and improving development outcomes. She highlights the fact that the World Bank's Women, Business and the Law reports analyze countries’ legislation to assess the legislative differences in the treatment of men and women in accessing economic opportunities. These reports have repeatedly found that economies become more resilient when societies pursue and implement policies aimed at achieving gender equality. The World Bank has consistently supported efforts to mainstream gender in policies, programs, and projects, as well as monitor the development outcomes of gender-related interventions. The World Bank recognizes that ensuring gender equality is not only a matter of human rights but also “smart economics”.

Many freshwater fish farming activities are carried out to meet the increasing demand for fish consumption. One commodity with high market demand is African catfish (Clarias gariepinus). The success of cultivation activities is the maintenance of broodstock is very influential on the eggs production. It is necessary to pay attention to the nutrients in the feed during cultivation. This study aims to determine the effect of adding soybean oil to feed on hatching eggs carried out at the Regional Technical Implementation Unit (UPTD) of Freshwater Aquaculture, Denpasar City. African catfish (C. gariepinus) were fed twice a day with feed mixed with soybean oil with three treatments namely 0%, 3% and 5% for five months. The fecundity and hatchability of eggs were calculated using a 10x10cm transect and analyzed using ANOVA analysis. Water quality observations were carried out once a week and ammonia at the end of each month. The results of this study obtained that fecundity values ranged from 214-546 grains/transect and egg hatchability values ranged from 0-62,62%. The results of observations of water quality showed a value that could still be tolerated by African catfish during the study. These results indicate that adding of 3% soybean oil to the broodstock feed of African catfish helps to increase the quality and quantity of hatching eggs.

This study aims to examine the effect of standardized social responsibility disclosure on earnings management and the role of management credibility in this relationship. The research sample is a company going public in the non-financial sector on the Indonesia Stock Exchange that has disclosed GRI-based social responsibility for the 2013-2019 period. The analysis technique used in this study is moderated regression analysis (MRA). The results of the study found that disclosure of social responsibility has a negative effect on earnings management and management credibility strengthens this relationship. The results of the study indicate that companies that put more effort into disclosing their social responsibility through standardized disclosures will reduce earnings management practices and this is reinforced by the existence of a credible management team. The novelty of this study lies in the use of a comprehensive index in measuring social responsibility disclosure which is a combination of aspects of accountability and performance, as well as the formulation of management credibility measurements.

Bananas are easily damaged, improper management of bananas can result in a decrease in quality and quality. In general, to measure maturity is still done conventionally, the weakness of this method is the level of accuracy that is not consistent and prone to errors. Utilization of images is very important to determine the ripeness of bananas by utilizing digital images. With the existence of digital images, to determine the ripeness of bananas based on their color can be done computationally (technology-based), namely by applying image processing using the HSV (Hue, Saturation, Value) color space transformation method. The HSV (Hue, Saturation, Value) color model classifies the intensity components of the conveyed color information (hue and saturation) in image colors. Based on the results of research on the analysis of the maturity level of bananas, the highest training accuracy is 100% and the highest testing accuracy is 100%. Meanwhile, in the analysis of coffee bean quality, the highest training accuracy was 87.5% and the highest testing accuracy was 90%. This accuracy indicates that the method developed in this study is quite good in analyzing the level of ripeness and quality of bananas. The developed system is also made in an interface that makes it easier for users to operate.

The Gender Performances of Margaret Atwood’s Aunt Lydia in "The Testaments"
Authors: Weiss Jordyn
Published: May 2023

This article examines the different gender performances that are demonstrated by three versions of the character Aunt Lydia: first, the Aunt Lydia of the novel version of The Handmaid’s Tale (Atwood, 2010); second, the television version of the same character for the Hulu series, The Handmaid’s Tale; and third, the Aunt Lydia that Margaret Atwood focuses on in her latest novel, The Testaments (2019). The research is primarily informed by Judith Butler and her various works on the subject of gender performativity. The Handmaid’s Tale novel’s Aunt Lydia performs the gender role of Gileadean Aunt. In the TV adaptation of the novel, Lydia continues her performance of the Aunt gender role, but audiences are also provided with a glimpse into Lydia’s pre-Gileadean gender performances. Finally, in The Testaments, Lydia performs multiple gender roles: that of the Aunt, as the other versions of her character do, and, in private, that of a woman who aims to restore Gileadean women’s freedom.
