Factors Controlling the Distribution of Agglutinated Foraminiferal Morphogroups as Palaeoenvironmental Tracers in the Kharga Oasis, Egypt
Authors: Orabi Orabi H. , Malarkodi N. , Zahran E. 
Published: March 2022

Abstract
The present authors used the scanning electron microscopy and energy dispersive spectroscopy methodology as a standard approach for micropaleontological studies to detect test internal morphological and compositional features of agglutinated foraminifera grains collected from Maastrichtian-Paleogene of the Dakhla Oasis of Egypt.
Five main morphogroups dominate Lower Kharga Member,the mixture of infaunal and epifaunal morphogroups indicating mesotrophic conditions during that time.All evolving new species found in the Early Paleocene are small and species richness remains low with small simple test morphologies resembling the under zone CF3 with a new appearance of morphogroup epifaunal flattened planispiral.
Zone CF3 of Lower Kharga Member is characterized by the appearances of small-sized Trochammina which are associated with stressful environmental conditions. Zone P1c of the Upper Kharga Member is characterized by high percentages of calcareous agglutinated foraminifera and abundance of granular calcite and hyaline tests, which explained a sufficient quantity of calcium carbonate dissolved in the water and warm water basin. The strong decrease in diversity and heterogeneity of the assemblages, as well as the drastic drop in the number of infaunal elongated morphogroup coincident with the hiatus between CF3 and P1c (Maastrichtian/Danian boundary), indicate a dramatic decrease in the food supply to the sea-bottom floor.
Stream Sediment Geochemical Survey of Rare Earth Elements in and Around Daringbadi, Kandhamal District, Odisha
Authors: Patel D.K. 
Published: March 2022

Abstract
There are number of Rare Earth Element (REE) bearing minerals, which get into the stream sediment by weathering of host rock.A chemical analysis of the stream sediment samples help to delineate the source rock, as they represent the composition of the drainage basin. So with main objective to identify new prospective areas for possible occurrences of mineral deposits on the basis these stream sediment samples, Geological Survey of India launched a national geochemical mapping programme in 2001. During the FS 2018-19 geochemical mapping was carried out in and around Daringbadi, Kandhamal district, Odisha in parts of toposheet no. 74A01. To study the distribution of REE group of elements in the stream sediment samples of the study area, 364 nos. of stream sediment/slope wash samples were collected on 1km x 1km grid interval constituting 91 nos. of composite samples.The collected samples were processed and analysed by inductively coupled plasma-mass spectrometer (ICP-MS) in GCM Lab, GSI, ER, Kolkata. Analytical results of composite and Soil samples shows that in the study area average value of ∑REE is 666.81 ppm and higher concentration is found in the central part of the study area near Daringbadi village over granite gneiss, khondalite and charnockite rocks. Elements such as Pb and Zr have average concentration 3 to 3.5 times higher than the average UCC value which may be due to the presence of charnockite.
EU Enlargement in Disregard of the Rule of Law: A Way Forward Following the Unsuccessful Dispute Settlement Between Croatia and Slovenia and the Name Change of Macedonia
Authors: Basheska Elena 
Published: March 2022

AbstractEU enlargement has always been a political process. That said, the rule of law is an important aspect and principle of the EU enlargement policy. Implementation of EU driven reforms in candidate countries largely depends on the rule of law-based enlargement as well as on a clear EU perspective. Overpoliticisation of the enlargement process renders the EU’s enlargement law futile and undermines both the transformative effect of the pre-accession process and EU’s own values. The implementation of the enlargement condition for settlement of bilateral disputes, which became pronounced in the EU enlargement towards the Western Balkan countries, is having the negative effect of contributing to deterioration rather than promotion of the rule of law in both EU candidate countries and the EU’s enlargement process. Lack of predictability and rule of law accordingly, makes the effective application of the principle of conditionality impossible. A genuine reconsideration of the condition for settlement of bilateral disputes within the EU enlargement framework, clear EU perspective and viable way forward are urgently needed for bringing rule of law and the EU’s credibility on track.
Linking Gains to Wrongs
Authors: Gilboa Maytal 
Published: March 2022

AbstractThis article provides a theoretical and doctrinal explanation of how the but-for test links gains to the wrong that produced them. Gain-based damages cases focus on the gain resulting from the defendant’s tortious behaviour. In these cases, the contrastive aspect of the but-for test, requiring the factfinder to consider the hypothetical result that would have occurred had the right thing happened instead of the defendant’s wrongdoing, is not confined to the question of reasonability, as it is in negligence cases. Rather, in gain-based damages cases, the factfinder faces the open-ended normative task of determining the hypothetically appropriate scenario that contrasts with the wrongdoing that happened in reality. For this reason, in gain-based damages cases, the normative sensitivity of the but-for test is revealed in full. The article explains how this sensitivity influences the result of the but-for test expressing the amount of gain causally attributed to the defendant’s wrongdoing.
Ergodicity of Iwasawa continued fractions via markable hyperbolic geodesics
Authors: LUKYANENKO ANTON , VANDEHEY JOSEPH 
Published: March 2022

AbstractWe prove the convergence and ergodicity of a wide class of real and higher-dimensional continued fraction algorithms, including folded and$\alpha $-type variants of complex, quaternionic, octonionic, and Heisenberg continued fractions, which we combine under the framework of Iwasawa continued fractions. The proof is based on the interplay of continued fractions and hyperbolic geometry, the ergodicity of geodesic flow in associated modular manifolds, and a variation on the notion of geodesic coding that we refer to as geodesic marking. As a corollary of our study of markable geodesics, we obtain a generalization of Serret’s tail-equivalence theorem for almost all points. The results are new even in the case of some real and complex continued fractions.

RésuméCette note de recherche a deux objectifs. Premièrement, nous présentons l'index relatif de confiance (IRC), une nouvelle mesure du potentiel de croissance et de la solidité du vote basée sur la probabilité exprimée par les électeurs de voter pour l'ensemble des partis dans leur circonscription. Nous nous penchons en détail sur les avantages de l'IRC et montrons qu'il permet d’évaluer le potentiel de croissance et la solidité du vote des partis politiques au niveau des circonscriptions et au niveau provincial. Deuxièmement, nous appliquons cet index au cas du Parti québécois à l'aide d’échantillons de grandes tailles récoltés pendant les campagnes électorales québécoises de 2012, 2014, et 2018. Cela nous permet d'illustrer et de tirer des constats sur le potentiel de croissance du Parti québécois.

AbstractGenomic surveillance has shaped our understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. We performed a global landscape analysis on SARS-CoV-2 genomic surveillance and genomic data using a collection of country-specific data. Here, we characterize increasing circulation of the Alpha variant in early 2021, subsequently replaced by the Delta variant around May 2021. SARS-CoV-2 genomic surveillance and sequencing availability varied markedly across countries, with 45 countries performing a high level of routine genomic surveillance and 96 countries with a high availability of SARS-CoV-2 sequencing. We also observed a marked heterogeneity of sequencing percentage, sequencing technologies, turnaround time and completeness of released metadata across regions and income groups. A total of 37% of countries with explicit reporting on variants shared less than half of their sequences of variants of concern (VOCs) in public repositories. Our findings indicate an urgent need to increase timely and full sharing of sequences, the standardization of metadata files and support for countries with limited sequencing and bioinformatics capacity.

Robust MPC for tracking changing setpoints in discrete‐time non‐linear systems with non‐additive unknown disturbance
Authors: Zamani Abbas , Bolandi Hossein 
Published: March 2022

AbstractThis paper develops a novel observer‐based robust tracking predictive controller for discrete‐time nonlinear affine systems capable of dealing with changing setpoints and non‐additive non‐slowly varying unknown disturbance with bounded variations. The existence of disturbance and/or sudden changes in a setpoint may lead to feasibility and stability issues in the stabilizing terminal constraint‐based MPC. Since robust tracking MPCs usually consider additive disturbance, the recursive feasibility of these methods may be lost in the presence of non‐additive non‐slowly varying disturbance. The robust tracking MPC presented here extends the artificial reference‐based MPC to deal with both changing setpoints and non‐additive non‐slowly varying disturbance. The key idea is the addition of tightened input and state constraints as new system constraints. The authors also guarantee the boundedness of disturbance observation error and closed‐loop tracking error. In this method, the optimal tracking error converges asymptotically to the terminal region, and the perturbed system tracking error remains in a variable size tube around the optimal tracking error. It is shown that the proposed controller can achieve offset‐free tracking in the presence of constant disturbance. The simulation results of the satellite attitude control system are provided to demonstrate the efficiency of the proposed predictive controller.
An end‐to‐end perceptual enhancement method for UHD portrait images
Authors: Yang Ying , Yang Mengning , Zhang Xin 
Published: March 2022

AbstractAdvances in equipment enable photographers to take ultra‐high‐definition (UHD) photos, and photo retouching enables them to create an impressive image by artistically adjusting and enhancing the brightness, color etc. However, such image enhancement is an artistic and challenging task, which requires a lot of relevant experience and technology. Thus, using an automated algorithm is an attractive option. In recent years, deep learning has made great progress in image processing, which motivated the authors to explore this application in UHD image enhancement task. In this paper, an end‐to‐end perceptual enhancement method for UHD portrait images is proposed. Since the artistry of images comes from human perception, including the perception of exposure, structure, color etc., an image preprocessing method is proposed which can help the network learn the brightness change from the original image to the target image more accurately. Then, a composite perceptual loss function is proposed that combines global, structural, and color losses. This loss allows the network to simultaneously optimize the distance and perceptual similarity to a given target image during back‐propagation. To preserve the details of the UHD image and reduce the number of network calculations and parameters, a Perceptual Enhancement Network (called PEN) based on dilated convolution is proposed. Extensive experiments on the datasets show that the method excels in baselines in both subjective and objective evaluations.
Psychomotricité et émergence de la représentation
Authors: Orjubin Jean-Marc 
Published: March 2022

Cet article cherche à rendre compte de la pertinence de la thérapeutique psychomotrice près d’enfants suivis en pédopsychiatrie, dans l’appropriation des étapes nécessaires à la genèse de la représentation. L’intérêt de la clinique psychomotrice se fonde sur une acceptation de la complexité interrogeant de façon permanente et essentielle les liens entre corps, pensée et relation. La place du psychomotricien dans ce contexte est celle d’être un véritable « sujet médiateur », réceptacle et transformateur de la forme singulière et fondatrice de l’interrelation, celle du dialogue tonique, émotionnel et affectif. C’est dans le soutien et l’élaboration de ce dialogue corporo-psychique, véritable matrice identificatoire, que surviennent les prémices des représentations naissantes, permettant à l’enfant d’accéder progressivement au sentiment « d’être-soi ».
Les néologismes psychotiques
Authors: Brémaud Nicolas 
Published: March 2022

Depuis Snell (1852) de très nombreux psychiatres et psychanalystes se sont interrogés sur les néologismes psychotiques. Classiquement ils sont subdivisés en néologismes passifs et en néologismes actifs (Lefèvre, Séglas), suivant en cela un processus « automatique » ou un processus « volontaire ». Le mot inventé, selon Séglas, « dit tout », autrement dit, « dit tout » de la pensée délirante du sujet, comme s’il en venait condenser, synthétiser les éléments, s’imposant dès lors comme une évidence. Aussi le néologisme aurait-il un « poids » suffisant qui permettrait au sujet de s’en contenter et de n’avoir plus rien à expliquer. Au-delà de cette singularité du langage, au-delà du seul aspect sémiologique et de son intérêt pour le diagnostic différentiel, nous verrons que le néologisme s’impose en quelque sorte de l’« extérieur », et s’impose parfois comme une nécessité. C’est dire qu’il ne peut simplement être un « signe » pour le clinicien, et qu’il ne peut endosser le vêtement du déficit. Bien au contraire, cette création, cette invention même, doit bien avoir une fonction pour le sujet. Ce sont des mots ou expressions qui sortent du langage commun, qui se séparent de la langue dite « maternelle », qui doivent être distingués du mot d’esprit, et qui mettent en relief le rapport singulier du sujet à son Autre, qui ont en certains cas (schizophrénie) une fonction de régulation dans le rapport à l’Autre, à la jouissance, et à la pensée même du délirant, dont la réalité, le rapport au monde, pourrait sans ce soutien partir à la dérive.

AbstractTreatment of N-propargyl-N′-tosylhydrazines with molecular iodine (I2) in the presence of NaHCO3 under warming conditions gave efficiently the corresponding 5-substituted 4-iodo-1-tosylpyrazoles in good to moderate yields. In addition, the same reaction in the presence of acetic acid generated the corresponding 5-aryl-4-iodopyrazoles in moderate yields. The reactions are simple and efficient transition-metal-free methods for the preparation of 5-substituted 4-iodo­pyrazole unit.
“Catheter-Locking Device-Assisted” External Ventricular Drain Placement: A New Surgical Technique Preventing Intracranial Drain Displacement—Technical Note with Preliminary Single-Center Results
Authors: Scafa Anthony Kevin , Jiang Tingting , Piccirilli Manolo 
Published: March 2022

Abstract

Background External ventricular drain (EVD) placement is frequently performed in neurosurgical patients to divert cerebrospinal fluid (CSF) and monitor intracranial pressure. The traditional practice is the tunneled EVD technique performed in the operating room. EVD insertion through a bolt in intensive care units has also been reported. We describe here the usage of a novel technique, the “catheter-locking device-assisted” EVD placement, reporting our preliminary, observational single-center results.

Methods From January to October 2021, 15 patients underwent a “catheter-locking device-assisted” EVD placement at our institute. For each of these patients, the following data were evaluated: (1) demographics, (2) etiology, (3) clinical presentation, (4) EVD complications, and (5) final clinical outcomes.

Results Median age of our population was 64 years, with a female/male ratio of 2:1. Average Glasgow Coma Scale score on admission was 8. Each patient maintained the drainage for an average time of 14 days. None of the patients suffered from postoperative intracerebral hemorrhage, CSF leakage, catheter migration, or discontinuation of the drainage system; none developed signs of infection. Nine patients required a permanent CSF diversion system. Outcome was good in 14 patients. One patient died for the underlying disease.

Conclusions The “catheter-locking device-assisted” EVD placement appears to be a safe and accurate alternative to both the standard tunneled and the bolt-assisted EVD insertion techniques. The use of this procedure may significantly reduce the incidence of the commonest EVD complications, though further investigation is required.
Soil salinity indicators and salinity build-up on saline water irrigation in seed spices
Authors: Chandel Sumita , Datta Ashim , Yadav R. K. 
Published: March 2022

Context Soil salinity is a major constraint in crop production in arid and semiarid regions where saline water is the main irrigation source affecting soil quality and crop productivity. Aims A pot experiment was conducted to study the impact of alternate application of saline water (electrical conductivity (EC): 6.0 dS m−1) and fresh water on soil salinity indicators and salinity build-up under four seed spices (Anethum graveolens L., Nigella sativa L., Pimpinella anisum L. and Trachyspermum ammi L.). Methods Soil samples were collected from a pot experiment (0–15 cm depth) conducted at ICAR-Central Soil Salinity Research Institute, Karnal, Haryana, and analysed for different physicochemical properties (pH and EC), cationic (Ca2+, Mg2+, Na+ and K+) and anionic (CO32−, HCO3−, Cl−, SO42−) concentration and their contribution to salinity build-up in soil. Key results Soil EC varied between 0.45 and 8.27 dS m−1 (EC1:2) and between 1.20 and 24.90 dS m−1 (ECe) irrespective of the seed spice species. The application of saline water in the early stages of growth followed by fresh-water irrigation resulted in a comparatively low ECe, and cation and anion concentrations over continuous saline-water irrigation irrespective of the seed spice crop. ECe, sodium adsorption ratio, potassium and pHs are the important indicators identified by principal component analysis and better explained soil salinity under this situation. Conclusions Keeping these in view, there is a need for cyclic use of saline and fresh water in growing seed spice crops to prevent soil degradation. Study recommends that these four seed spice crops should be irrigated with fresh water during crop establishment and flowering stage, whereas, in between, saline water can be applied. Implications Such management of saline water irrigation could help to reduce salinity and maintain soil health for sustaining crop productivity, specifically for seed spices, in arid and semiarid regions.
Emergent elastic fields induced by topological phase transitions: Impact of molecular chirality and steric anisotropy
Authors: Takae Kyohei , Kawasaki Takeshi 
Published: March 2022

SignificanceChirality, the property of an object that cannot be superimposed on its mirror image, plays an essential role in condensed matter, such as magnetic, electronic, and liquid crystal systems. Topological phases emerge in such chiral materials, wherein helical and vortex-like structures—called skyrmions—are observed. However, the role of elastic fields in these topological phases remains unexplored. Here, we construct a molecular model of two-dimensional crystals incorporating steric anisotropy and chiral interactions to elucidate this problem. The coupling between the elastic fields and phase transitions between uniform, helical, and half-skyrmion phases can be utilized to switch these topological phases by external forces. Our results provide a fundamental physical principle for designing topological materials using chiral molecular and colloidal crystals.

Significance
A clear mechanistic understanding of metformin’s antidiabetic effects is lacking. This is because suprapharmacological concentrations of metformin have been used in most studies. Using mouse models and human primary hepatocytes, we show that metformin, at clinically relevant doses, suppresses hepatic glucose production by activating a conserved regulatory pathway encompassing let-7, TET3, and a fetal isoform of hepatocyte nuclear factor 4 alpha (HNF4α). We demonstrate that metformin no longer has potent antidiabetic actions in a liver-specific let-7 loss-of-function mouse model and that hepatic delivery of let-7 ameliorates hyperglycemia and improves glucose homeostasis. Our results thus reveal an important role of the hepatic let-7/TET3/HNF4α axis in mediating the therapeutic effects of metformin and suggest that targeting this axis may be a potential therapeutic for diabetes.
