A predictive model to estimate post-donation glomerular filtration rate (eGFR) and risk of CKD at 1-year was developed from a Toulouse-Rangueil cohort in 2017 and showed an excellent correlation to the observed 1-year post-donation eGFR. We retrospectively analyzed all living donor kidney transplants performed at a single center from 1998 to 2020. Observed eGFR using CKD-EPI formula at 1-year post-donation was compared to the predicted eGFR using the formula eGFR (CKD-EPI, mL/min/1.73 m2) = 31.71+ (0.521 × preoperative eGFR) − (0.314 × age). 333 donors were evaluated. A good correlation (Pearson r = 0.67; p &lt; 0.001) and concordance (Bland-Altman plot with 95% limits of agreement −21.41–26.47 mL/min/1.73 m2; p &lt; 0.001) between predicted and observed 1-year post-donation eGFR were observed. The area under the ROC curve showed a good discriminative ability of the formula in predicting observed CKD at 1-year post-donation (AUC = 0.83; 95% CI: 0.78–0.88; p &lt; 0.001) with optimal cutoff corresponding to a predicted eGFR of 65.25 mL/min/1.73 m2 in which the sensibility and specificity to predict CKD were respectively 77% and 75%. The model was successfully validated in our cohort, a different European population. It represents a simple and accurate tool to assist in evaluating potential donors.
Les pouvoirs « périphériques » des présidents d'Europe post-communiste : symboles ou pouvoirs réels ?
Authors: Frison-Roche François 
Published: March 2023

The "peripheral" powers of presidents in post-communist Europe: Symbolic or real?
The constitutions of post-Communist countries in Europe grant to the president of the republic a panoply of constitutional powers of the sort found in several Western constitutions. A majority of these presidents are elected directly through universal suffrage and have powers (said to be "peripheral" herein since their importance is not obvious) enabling them to play an essential role in politics. These constitutionally granted powers - over the army, intelligence services and national security council, and in emergencies - expose the ambiguity of the persons and parties involved in the post-Communist transition during the 1990s. Most of them wanted to arrange for a sharing of power through the adoption of a mixed (semi- presidential) institution rather than to establish a truly parliamentary or presidential system.
L'institutionnalisation des compétences implicites du Président russe et leur rôle dans le fonctionnement du pouvoir présidentiel

Published: March 2023

Institutionalizing the Russian president's "implicit" powers: The exercise of presidential power
The "implicit" powers of the president of Russia are not described in the constitution or are mentioned in very general, ambiguous terms. Alongside classical presidential prerogatives, the president has the power, for instance, to create advisory organs, head certain ministries and administrations, make appointments to major positions and give instructions to various authorities. This scope of action has considerably expanded the presidency. The contents of these "implicit" powers, their institutionalization since 1990 and the effect of administrative practices from the Soviet era in exercising them are analyzed. The effects of these powers on the Russian political system are examined.
Le développement rural en Lituanie : entre désengagement de l'État, émergence d'une société civile et apprentissage des outils européens
Authors: Maciulyte Jurgita 
Published: March 2023

Rural development in Lithuania: Between government withdrawal, the emergence of "civil society" and learning how to use European policy tools
Dismantling the collectivistic model in the 1990s has led to strong social differentiation in rural societies and disrupted operations there. The generalized bankruptcy of the farms formed out of the privatization of kolkhozes and sovkhozes has resulted in unemployment and poverty. It has also destroyed social and cultural infrastructures, and seriously affected living conditions in the countryside. Despite this worrisome social and economic situation, rural policies have, during the first decade after the country's return to independence, exclusively focused on farming and modernizing commercial farms. Since Lithuania joined the EU in 2004, the government has been forced to formulate a policy in line with the EU's, which provides financial and technical support mainly through the LEADER initiative (Links between Actions for the Development of the Rural Economy). After an initial experimental phase (2004-2006) centered around funding educational projects, the program has, for the period 2007-2013, adopted a broad policy of diversifying economic activities and renovating villages by drawing on projects worked out by local action groups — the new public and private actors touted by the EU. A lack of democracy and institutional shortcomings at the district level limit this transfer of the European model. Light is shed on the growing importance of the "rural communities" and local action groups that sprung up in the countryside during the 1990s in reaction to reduced government support.
ASSOCIATION BETWEEN THE EXPRESSION OF PRO-INFLAMMATORY CYTOKINES TNF-Α, IL-1B, IL-6, C-REACTIVE PROTEIN AND THE STATE OF INSULIN RESISTANCE IN OVERWEIGHT WOMEN ON PRECONCEPTIONAL PERIOD AND IN PREGNANCY
Authors: MAKSYMENKO L. 
Published: March 2023

Metabolic disturbances and immune dysregulation cause adipose tissue stress and dysfunction in overweight individuals. The accumulation of immune cells in the fat microenvironment is considered to be the cause of insulin resistance and metabolic dysfunction.
The objective of the study was to evaluate the relationship between the indicators of the proinflammatory cytokine profile and the development of insulin resistance state in overweight women on preconceptional period and in pregnancy.
Material and methods. 117 women (68 with excessive and 49 with normal body weight) were studied on preconceptional period and at 9-12, 37- 40 weeks of pregnancy. The percentage of body fat mass (BFM) was diagnosed based on spectral bioimpedance measurement; serum concentrations of glucose and insulin by the immunoenzymatic method; insulin resistance index (HOMA-IR); the cytokines levels - tumor necrosis factor-alpha (TNF-a, interleukins (IL-1b IL-6) - “Diaclone” test system (France), C-reactive protein (CRP) -”Diagnostik Automatik Ins” (USA) by ELISA method. Statistica 10 statistical analysis package (Serial Number: STA999K347150-W) and MEDCALC® were used
Results. The study demonstrated higher levels of inflammatory mediators (TNF-a, IL-1b, IL-6, CRP) in overweight women and the presence of insulin resistance on preconceptional period. Pregnancy in overweight women is characterized by higher levels of pro-inflammatory cytokines compared to normal weight group. A relationship was studied between the percentage of BMI and TNF-a (r=0.87, p<0.001), IL-1b (r=0.84, p<0.001), IL-6 (r=0.87, p<0.001) and CRP (r=0.87, p<0.001) in the third trimester. A positive correlation between the levels of pro-inflammatory cytokines and the HOMA-IR was determined. It is shown that the risks of developing gestational diabetes increase in the presence of initial excessive body weight (OR=8.28; 95% CI:1.02-66.97; p=0.04), the state of insulin resistance on preconceptional period (OR=9.97; 95% CI: 2.22-44.83; p=0.002). In the group of patients with gestational diabetes the level of pro-inflammatory cytokines exceeded the indicators of the group of pregnant without gestational diabetes in the first trimester (TNF-a by 1.7 times, IL-1b by 1.2 times, IL-6 by 1.5 times, and CRP in 1.7 times) (p<0.05) with an elevation until the labor.
Conclusion. It has been proven that the increased expression of pro-inflammatory cytokines TNF-a, IL-1b, IL-6 and CRP during pregnancy is associated with a violation of tissue sensitivity to insulin, which increases in the presence of preconceptional excessive body weight with an increased risk of developing gestational diabetes.
CLINICAL RESULTS IN WOMEN WITH FERTILITY DUE TO ENDOMETRIOS IN THE PROTOCOLS OF ASSISTED REPRODUCTIVE TECHNOLOGIES
Authors: KHMIL S.V. , PIDHAINA I.YA. 
Published: March 2023

Surgical treatment of ovarian endometriosis remains a controversial issue. Sclerotherapy of endometrioma as a minimally invasive and affordable method proves its effectiveness for this category of patients, confirming it with clinical results in ART protocols.
The aim is to study the effectiveness of protocols of controlled ovarian stimulation using protocol pretreatment therapy and sclerotherapy in patients with endometriosis-associated infertility in assisted reproductive technology programs.
Materials and methods. 126 women with endometriosis-associated and tubal infertility were examined. The patients were divided into 3 clinical groups. Group 1 – 51 patients with infertility on the background of endometriosis, who, 2 months before the COS protocol with GnRH antagonists, underwent a course of protocol pretreatment therapy with sclerotherapy of the endometrioid cyst. Group 2 consisted of 45 patients with infertility on the background of endometriosis, who had a history of surgical treatment. Group 3 includes 30 women with tubal factor infertility, who were a control group. Depending on the treatment tactics, the clinical results of women of both research groups and the control group in ovulation stimulation protocols in ART programs were analyzed.
Results. The mean number of retrieved oocytes from patients with endometriosisassociated infertility who underwent conservative endometrioma treatment, as well as the mean number of mature oocytes (MII), the mean number of immature oocytes (MI), and the mean number of deeply immature oocytes (GV) were actually statistically do not differ from the number of oocytes in the same sorting in the control group of women with tubal factor infertility, but it is statistically significantly different between the women of the experimental groups with endometriosis-associated infertility who underwent conservative and operative treatment of ovarian endometriosis, (p1- 2<0.05 )*. In women who underwent endometrioma cystectomy, the ovulatory reserve significantly decreased due to a decrease in the absolute number of follicles, as well as their quality, which affected the subsequent clinical results of women in ART protocols.
Conclusions. The fact of the negative impact of endometriosis on the reproductive system and the woman’s body as a whole is proven by the clinical results of patients. Surgical treatment poses a serious risk to women with low ovulatory reserve. Preservation of the follicular apparatus, preservation of the quality of eggs offered by the method of sclerotherapy and protocol pretreatment therapy can increase the chances of success in women with infertility due to endometriosis in ART programs.

Abstract
Radiation tolerance of Cu(In,Ga)Se2 (CIGS) solar cells has been investigated using high-fluence proton beam irradiation for application to devices in extremely-high-radiation environments. CIGS solar cells deteriorated after high-energy proton irradiation with non-ionizing energy loss of 1 × 1016 MeVneq cm−2, however, the CIGS solar cells could generate power after high-fluence irradiation. The ideality factors increased from 1.3 to 2.0, and series resistance increased, indicating that the concentration of recombination centers increased in CIGS layers. After heat-light annealing, the conversion efficiencies gradually recovered, and the recombination centers were confirmed to be partly passivated by annealing at 90 °C. The short-circuit currents for 10 μm thick CIGS solar cells were recovered by dark annealing in the same manner as for 2 μm thick CIGS solar cells. Dark annealing on irradiated CIGS solar cells has beneficial effects on passivate the recombination centers, even using thicker CIGS layers.

On the hit problem for the polynomial algebra and the algebraic transfer
Authors: Võ Phúc Đặng 
Published: March 2023

<p>Let $\mathcal A$ be the classical, singly-graded Steenrod algebra over the prime order field $\mathbb F_2$ and let $P^{\otimes h}: = \mathbb F_2[t_1, \ldots, t_h]$ denote the polynomial algebra on $h$ generators, each of degree $1.$ Write $GL_h$ for the usual general linear group of rank $h$ over $\mathbb F_2.$ Then, $P^{\otimes h}$ is an $\mathcal A[GL_h]$-module. As well known, the (mod 2) cohomology groups of the Steenrod algebra, ${\rm Ext}_{\mathcal A}^{h, h+*}(\mathbb F_2, \mathbb F_2)$ is still largely mysterious for all homological degrees $h \geq 6.$ The $h$-th algebraic transfer $Tr_h^{\mathcal A}: (\mathbb F_2\otimes_{GL_h}{\rm Ann}_{\overline{\mathcal A}}[P^{\otimes h}]^{*})_n\longrightarrow {\rm Ext}_{\mathcal A}^{h, h+n}(\mathbb F_2, \mathbb F_2),$ defined by Singer [Math. Z. \textbf{202} (1989), 493-523], is a helpful tool to describe that Ext groups. Singer conjectured that this homomorphism is a monomorphism for any $h>0.$ There is currently no information about the conjecture for $h = 6.$ The purpose of this Note is to study Singer's conjecture for all $h\geq 1$ in degrees $n\leq 10 = 6(2^{0}-1) + 10\cdot 2^{0}$ and for $h=6$ in general degree $n:=n_s=6(2^{s}-1) + 10\cdot 2^{s},\, s\geq 0.$ Our approach is based on techniques of the hit problem for $P^{\otimes h}.$ This also extends a result in Mothebe et al. [J. Math. Res. \textbf{8} (2016), 92-100] on the hit problem for $P^{\otimes 6}$ in degree $n_s.$ More generally, for $h\geq 6,$ we show that the dimension of the cohit module $\mathbb F_2\otimes_{\mathcal A}P^{\otimes h}$ in degrees $2^{s+4}-h$ is equal to the order of the factor group of $GL_{h-1}$ by the Borel subgroup $B_{h-1}$ for every $s\geq h-5.$ Especially, for the Galois field $\mathbb F_{q}$ ($q$ denoting the power of a prime number), based on Hai's recent work [C. R. Math. Acad. Sci. Paris \textbf{360} (2022), 1009-1026], we claim that the dimension of the space of the indecomposable elements of $\mathbb F_q[t_1, \ldots t_h]$ in degrees $q^{h-1}-h$ is equal to the order of the factor group of $GL_{h-1}(\mathbb F_q)$ by a subgroup of the Borel group $B_{h-1}(\mathbb F_q).$ As applications, we establish the dimension result for the cohit module $\mathbb F_2\otimes_{\mathcal A}P^{\otimes 7}$ in degrees $n_{s+5},\, s > 0.$ At the same time, we prove that the non-zero elements $h_2^{2}g_1 = h_4Ph_2\in {\rm Ext}_{\mathcal A}^{6, 6+n_1}(\mathbb F_2, \mathbb F_2)$, and $D_2\in {\rm Ext}_{\mathcal A}^{6, 6+n_2}(\mathbb F_2, \mathbb F_2)$ are not in the image of $Tr_6^{\mathcal A}.$ We also give some conjectures on the $h$-th cohomology groups of the algebra $\mathcal A$ for $h\geq 6,$ and discuss their relationship to previous works. </p>
Quantifying Prediction Uncertainty in Regression using Random Fuzzy Sets: the ENNreg model
Authors: Denoeux Thierry 
Published: March 2023

<p>We introduce a neural network model for regression in which prediction uncertainty is quantified by Gaussian random fuzzy numbers (GRFNs), a newly introduced family of random fuzzy subsets of the real line that generalizes both Gaussian random variables and Gaussian possibility distributions. The output GRFN is constructed by combining GRFNs induced by prototypes using a combination operator that generalizes Dempster's rule of Evidence Theory. The three output units indicate the most plausible value of the response variable, variability around this value, and epistemic uncertainty. The network is trained by minimizing a loss function that generalizes the negative log-likelihood. Comparative experiments show that this method is competitive, both in terms of prediction accuracy and calibration error, with state-of-the-art techniques such as random forests or deep learning with Monte Carlo dropout. In addition, the model outputs a predictive belief function that can be shown to be calibrated, in the sense that it allows us to compute conservative prediction intervals with specified belief degree.</p>

Published: March 2023

<p> A sector-shaped compact π/8 partial substrate-integrated waveguide cavity antenna from the TM220 diagonal mode of the SIW cavity is presented. A 61% size miniaturization is achieved compared to the SIW rectangular cavity in its complete mode configuration. The compact cavity radiator is used as an element of a compact 8-port multiple-input multiple-output (MIMO) antenna. The 8-port MIMO antenna occupies the entire full cavity with slots loaded on the top and bottom layers. The fabricated prototype has a -10 dB impedance bandwidth (BW) from 6.006-6.143 GHz. The mutual coupling within the BW is less than -21 dB. The presented MIMO antenna has an envelope correlation coefficient (ECC) less than 0.0027, and a percentage diversity gain reduction below 1.73%, which makes it a suitable candidate for use in MIMO-based wireless communications (This paper has been accepted for publication in <em>IEEE Antennas and Wireless Propagation Letters</em> )</p>
Multirate NOMA for Improving Connectivity in 6G Communications Networks

Published: March 2023

<p>In non-orthogonal multiple access (NOMA), user pairing, power allocation, and performance evaluation are typically performed while assuming that all users have equal symbol rates. However, such an assumption may significantly limit the design flexibility of NOMA and devalue its potential. Therefore, this paper considers a generalized scenario where the user-paring process may include users with different symbol rates, and thus, the proposed configuration is denoted as multi-rate NOMA (MRNOMA). In MR-NOMA, the relation between the symbol rate and energy is exploited to add a new degree of freedom when assigning power to the paired users. That is, the fact that the symbol energy is proportional to the symbol duration extends the range of power values that can be allocated to the high symbol rate user while satisfying the quality-of-service requirements for all users. Consequently, the number of served users can be increased, or such a feature can be used to increase the link throughput. The obtained results show that with optimal power selection, both the high and low symbol rate users can achieve lower bit error rates (BERs), which in turn increases the system throughput as a result of the improved transmission reliability. </p>
