Authors: SİLAV Zuhal
Published: September 2023

Amaç: Meme kanserinde immunhistokimyasal biyobelirteç olarak umut vaat eden Ki67 proteini, mitoz döngüsünün tüm aktif fazlarında bulunduğundan hücre proliferasyon değerlendirmelerinde kullanılır. Ki67 indeksi meme kanserli hastalarda prediktif ve prognostik değerdedir. Manuel değerlendirme (MD) ile Ki67 sayımı gözlemciler arası değişkenliğe hassas ve zaman alıcıdır. Son yıllarda, dijital görüntü analizinin (DGA) Ki67 ölçümleri için hızlı ve objektif olduğunu belirten çalışmalar artmaktadır ancak bu yöntemin rutin uygulamaya girmesi ileri çalışmaları gerektirmektedir. Bu araştırmada 85 invaziv meme kanseri vakasında MD, DGA ve GK (göz kararı) Ki67 ölçümlerini kıyaslanmıştır.
Yöntem: Tümör moleküler tipleri, mitoz sayıları, GK, MD ve DGA ile ölçülmüş Ki67 değerleri ve korelasyonları saptandı. DGA analizleri ViraPath (Virasoft Yazılım, İstanbul, Türkiye) yazılımıyla, parametreler arasında istatistik korelasyonlar NCSS (Number Cruncher Statistical System, 2020) ile incelendi.
Bulgular: Her üç farklı metotla belirlenmiş Ki67 indeks değerlerinin yaş, histolojik derece, mitoz sayıları ve moleküler tip açısından korelasyon ve farklılıkları literatür ile uyumlu bulundu. DGA ve MD ile sayılmış Ki67 indeksleri arasında sınıf içi korelasyon katsayısı 0,974 olarak ölçüldü ve Bland Altman analizleri ile MD ve DGA sayımları arasındaki fark sıfıra yakın saptandı.
Sonuç: DGA sayımları MD’nin yerini alacak güvenilirlikte sonuçlar vermektedir. Çok merkezli ve metot standartlarını optimize edecek çalışmalarla patoloji pratiğine zamansal katkı ve yüksek hassasiyet kazandırılabilir.

Irritadas/os por el Antropoceno. Por una sociología del Antropoceno (mientras sucede)
Authors: Biskupovic Consuelo
Published: September 2023

El desafío del Antropoceno, planteado desde las ciencias sociales, implica abordar cómo y qué se pierde, qué se recupera, qué desaparece. La articulación entre la política y la economía, tema central para las ciencias sociales desde su fundación, ya no puede pensarse igual en el contexto de la crisis ecológica. Para pensar en este nuevo escenario, en este texto retomamos cuatro puntos cruciales del texto de Tironi y Undurraga. El primero es la idea de que la naturaleza (o la ecología) no puede ser pensada aparte de la política; debemos tratar los asuntos de naturaleza y política como una sola cuestión que se manifiesta para todos los colectivos. El segundo es que se le ha prestado escasa atención a las configuraciones políticas que van más allá de la teoría de los (nuevos) movimientos sociales. El rol de los activismos y de las organizaciones ha sido un espacio escasamente considerado por la sociología chilena para pensar la crisis ambiental, aun cuando en Chile las/os ciudadanas/os han tenido históricamente un rol activo en temáticas ambientales. En tercer lugar abordamos el ‘cuerpo‘ afectado tanto por los efectos de la industria extractivista como por la crisis climática, recalcando la importancia de integrar al análisis cómo son experimentadas las intersecciones de pertenencia étnica, género, clase y territorio. Finalmente, abordamos cómo el concepto Antropoceno incomoda y su universalidad molesta. Esta nueva era geológica aparece como una categoría de contexto que nos excede y sobrepasa.

Repensar el Antropoceno. Un comentario a ‘Provocaciones y tensiones del Antropoceno: hacia una geologización de lo social’
Authors: Chernilo Daniel
Published: September 2023

Este breve comentario ofrece tres reflexiones al artículo ’Provocaciones y tensiones del Antropoceno: hacia una geologización de lo social’, de Manuel Tironi y Beltrán Undurraga. En primer lugar, se discute la idea de ’claroscuro’ que los autores utilizan para abordar sociológicamente el Antropoceno. Segundo, se critica la definición algo débil del concepto mismo de Antropoceno, que corre el riesgo de disolver buena parte de sus rendimientos más significativos. Finalmente, se toma distancia de su llamado a la ’sociología chilena’, desde una perspectiva tanto local como global.

Fast radio bursts (FRBs) are a class of highly energetic, mostly extragalactic radio transients lasting for ∼milliseconds. While over 600 FRBs have been published so far, their origins are presently unclear, with some theories for extragalactic FRBs predicting accompanying high-energy emission. In this work, we use the Canadian Hydrogen Intensity Mapping Experiment (CHIME) Fast Radio Burst (CHIME/FRB) Project to explore whether any FRB-like radio emission coincides in space and time with 81 gamma-ray bursts (GRBs) detected between 2018 July 17 and 2019 July 8 by Swift/BAT and Fermi/GBM. We do not find any statistically significant coincident pairs within 3σ of each other’s spatial localization regions and within a time difference of up to one week. In addition to searching for spatial matches between known FRBs and known GRBs, we use CHIME/FRB to constrain FRB-like (∼1–10 ms) radio emission before, at the time of, or after the reported high-energy emission at the position of 39 GRBs. For short gamma-ray bursts (SGRBs), we constrain the radio flux in the 400–800 MHz band to be under a few kJy for ∼5.5–12.5 hr post-high-energy burst. We use these limits to constrain models that predict FRB-like prompt radio emission after SGRBs. For long gamma-ray bursts, we constrain the radio flux to be under a few kJy from ∼6 hr pre-high-energy burst to ∼12 hr post-high-energy burst.
Black Hole Accretion with Saturated Magnetic Pressure and Disk Wind
Authors: Huang Jiahui , Feng Hua , Gu Wei-Min , Wu Wen-Biao
Published: September 2023

We construct an analytical black hole accretion disk model that incorporates both magnetic pressure and disk wind, which are found to be important from numerical simulations. A saturated magnetic pressure that relates the Alfvén velocity with local Keplerian velocity and gas sound speed is assumed in addition to radiation and gas pressures. The mass accretion rate is assumed to have a power-law form in response to mass loss in the wind. We find three sets of self-consistent solutions that are thermally stable and satisfy the model assumptions. At high accretion rates, the disk is geometrically and optically thick, resembling the slim disk solution. At relatively low accretion rates, our model predicts an accretion flow consisting of a geometrically thin and optically thick outer disk (similar to the standard disk), and a geometrically thick and optically thin inner disk (similar to the advection-dominated accretion flow, or ADAF). Thus, this is a natural solution for a truncated disk connected with an inner ADAF, which has been proposed to explain some observations. The magnetic pressure plays a more important role than the outflow in shaping the disk structure. The observed disk luminosity tends to saturate around 8 times the Eddington limit, suggesting that supercritical accretion onto black holes can be used for a black hole mass estimate, or a standard candle with known black hole masses.

We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method. Our selection consists of a set of color and surface brightness cuts, combined with modern machine-learning methods, to target low-redshift dwarf galaxies (z < 0.03) between 19 < r < 21 with high completeness. We employ a convolutional neural network (CNN) to select high-priority targets. The LOW-Z survey has already obtained over 22,000 redshifts of dwarf galaxies (M
* < 109
M
⊙), comparable to the number of dwarf galaxies discovered in the Sloan Digital Sky Survey DR8 and GAMA. As a spare fiber survey, LOW-Z currently receives fiber allocation for just ∼50% of its targets. However, we estimate that our selection is highly complete: for galaxies at z < 0.03 within our magnitude limits, we achieve better than 95% completeness with ∼1% efficiency using catalog-level photometric cuts. We also demonstrate that our CNN selections z < 0.03 galaxies from the photometric cuts subsample at least 10 times more efficiently while maintaining high completeness. The full 5 yr DESI program will expand the LOW-Z sample, densely mapping the low-redshift Universe, providing an unprecedented sample of dwarf galaxies, and providing critical information about how to pursue effective and efficient low-redshift surveys.
ALMA 0.5 kpc Resolution Spatially Resolved Investigations of Nuclear Dense Molecular Gas Properties in Nearby Ultraluminous Infrared Galaxies Based on HCN and HCO+ Three Transition Line Data
Authors: Imanishi 今西 Masatoshi 昌俊 , Baba 馬場 Shunsuke 俊介 , Nakanishi 中西 Kouichiro 康一郎 , Izumi 泉 Takuma 拓磨
Published: September 2023

We present the results of our ALMA ≲0.5 kpc resolution dense molecular line (HCN and HCO+
J = 2–1, J = 3–2, and J = 4–3) observations of 12 nearby (ultra)luminous infrared galaxies ([U]LIRGs). After matching beam sizes of all molecular line data to the same values in all (U)LIRGs, we derive molecular line flux ratios by extracting spectra in the central 0.5, 1, and 2 kpc circular regions and in 0.5–1 and 1–2 kpc annular regions. Based on non–local thermal equilibrium model calculations, we quantitatively confirm that the innermost (≲0.5 kpc) molecular gas is very dense (≳105 cm−3) and warm (≳300 K) in ULIRGs, and that in one LIRG, it is also modestly dense (104–5 cm−3) and warm (∼100 K). We then investigate the spatial variation of the HCN-to-HCO+ flux ratios and high-J to low-J flux ratios of HCN and HCO+. A subtle sign of a decreasing trend in these ratios from the innermost (≲0.5 kpc) to the outer nuclear (0.5–2 kpc) region is discernible in a significant fraction of the observed ULIRGs. For two ULIRGS hosting an active galactic nucleus (AGN), which display the trend most clearly, we find based on a Bayesian approach that the HCN-to-HCO+ abundance ratio and gas kinetic temperature systematically increase from the outer nuclear to the innermost region. We suggest that this trend comes from potential AGN effects because no such spatial variation is found in a starburst-dominated LIRG.
The Role of Pickup Ions in the Interaction of the Solar Wind with the Local Interstellar Medium. I. Importance of Kinetic Processes at the Heliospheric Termination Shock

Published: September 2023

The role of pickup ions (PUIs) in the solar wind interaction with the local interstellar medium is investigated with 3D, multifluid simulations. The flow of the mixture of all charged particles is described by the ideal MHD equations, with the source terms responsible for charge exchange between ions and neutral atoms. The thermodynamically distinct populations of neutrals are governed by individual sets of gas dynamics Euler equations. PUIs are treated as a separate, comoving fluid. Because the anisotropic behavior of PUIs at the heliospheric termination shocks is not described by the standard conservation laws (a.k.a. the Rankine–Hugoniot relations), we derived boundary conditions for them, which are obtained from the dedicated kinetic simulations of collisionless shocks. It is demonstrated that this approach to treating PUIs makes the computation results more consistent with observational data. In particular, the PUI pressure in the inner heliosheath (IHS) becomes higher by ∼40%–50% in the new model, as compared with the solutions where no special boundary conditions are applied. Hotter PUIs eventually lead to charge-exchange-driven cooling of the IHS plasma, which reduces the IHS width by ∼15% (∼8–10 au) in the upwind direction, and even more in the other directions. The density of secondary neutral atoms born in the IHS decreases by ∼30%, while their temperature increases by ∼60%. Simulation results are validated with New Horizons data at distances between 11 and 47 au.
Estimators of Bolometric Luminosity and Black Hole Mass with Mid-infrared Continuum Luminosities for Dust-obscured Quasars: Prevalence of Dust-obscured SDSS Quasars
Authors: Kim Dohyeong , Im Myungshin , Kim Minjin , Kim Yongjung , Shin Suhyun , Shim Hyunjin , Song Hyunmi
Published: September 2023

We present bolometric luminosity (L
bol) and black hole (BH) mass (M
BH) estimators based on mid-infrared (MIR) continuum luminosity (hereafter, L
MIR) that are measured from infrared (IR) photometric data. The L
MIR-based estimators are relatively immune from dust extinction effects, hence they can be used for dust-obscured quasars. To derive the L
bol and M
BH estimators, we use unobscured quasars selected from the Sloan Digital Sky Survey (SDSS) quasar catalog, which have wide ranges of L
bol (1044.62–1046.16 erg s−1) and M
BH (107.14–109.69
M
⊙). We find empirical relations between (i) continuum luminosity at 5100 Å (hereafter, L5100) and L
MIR; (ii) L
bol and L
MIR. Using these relations, we derive the L
MIR-based L
bol and M
BH estimators. We find that our estimators allow the determination of L
bol and M
BH at an accuracy of ∼0.2 dex against the fiducial estimates based on the optical properties of the unobscured quasars. We apply the L
MIR-based estimators to SDSS quasars at z ≲ 0.5 including obscured ones. The ratios of L
bol from the L
MIR-based estimators to those from the optical luminosity-based estimators become larger with the amount of the dust extinction, and a non-negligible fraction (∼15%) of the SDSS quasars exhibits ratios greater than 1.5. This result suggests that dust extinction can significantly affect physical parameter derivations even for SDSS quasars, and that dust extinction needs to be carefully taken into account when deriving quasar properties.
A new species of Zoraptera, Zorotypus komatsui sp. nov. from Cameroon and a redescription of Zorotypus vinsoni Paulian, 1951 (Polyneoptera, Zoraptera)

Published: September 2023

A new species of the order Zoraptera, Zorotypus komatsui Matsumura, Maruyama, Ntonifor & Beutel, sp. nov., is described from Cameroon. The female and male morphology of another species, Z. vinsoni, is re-described, and its new distribution in Madagascar is recorded. A particular focus is on the male postabdominal morphology. This is apparently a crucial body region in the very small order with an extreme variation of the genital apparatus but otherwise a very uniform morphology. The male of the newly described species shares rudimentary male genitalia and well-developed postabdominal projections with the distantly related Spermozoros impolitus, apparently a result of parallel evolution. Whether males of Z. komatsui also perform external sperm transfer like S. impolitus remains to be shown. The collecting of the material used for this study suggests that the present knowledge of zorapteran species diversity of the Afrotropical region is very fragmentary.

Authors: Pirouzmand Neda , Pereira Daniel , Sutton Mitchell , Mathew Ashish J. , Chandran Vinod , Gladman Dafna D.
Published: September 2023

Objective

To estimate the prevalence of coronavirus disease 2019 (COVID-19) infection among patients with psoriatic arthritis (PsA), understand patients’ perspectives regarding their risk of COVID-19 infection, and evaluate the standard of virtual care offered during the early phases of the pandemic.

Methods

An online survey was conducted between June 2021 and September 2021 in patients with PsA who had consented to email contact. The survey was completed by 152/193 (79%) patients who had consented to the study.

Results

There were 86 (56.6%) men and 66 (43.4%) women with a mean age of 58 years and mean disease duration of 19 years. During the pandemic, the mean patient-reported symptom severity was 4.10, 3.24, and 3.72 for joint, skin, and overall symptom severity, respectively. Seventy-four percent of respondents would accept the effect of their PsA over the past month for the next few months. Of 79 patients who were tested for severe acute respiratory syndrome coronavirus 2, 4 tested positive. All 4 were admitted to hospital; 2 required oxygen. One hundred fifty-one patients (99%) had received at least 1 vaccine dose. Fifty-nine (38.8%) participants believed their PsA medications increased their COVID-19 infection risk. Of the 130 patients who had a telemedicine assessment, 83.1% were happy with their virtual consultations. Most were happy to continue with virtual consultations until the pandemic resolved. The average satisfaction level regarding pandemic care was 7.87 on a sliding 10-point scale.

Conclusion

COVID-19 prevalence was low among our patients. Patients were satisfied with their care during the pandemic. Most patients would happily continue with virtual care for the duration of the pandemic.
Open interoperability model for Society 5.0's infrastructure and services
Authors: Gumzej Roman , Rosi Bojan
Published: September 2023

As the Internet of Things (IoT) is considered the foundation of digital transformation in everyday life, the Industrial IoT (IIoT) is considered its business counterpart. Together with the Physical Internet (PhI), they represent the foundation of smart production and logistics as part of the new digitized Society 5.0. Smart grids of different kinds with applications, ranging from power distribution to transportation, represent the infrastructure of smart cities and communities. Like with the PhI, they rely on the acceptance and integration of their services to fully unleash their potential. Hence, apart from the open interoperability model, which enables the interoperability and operational transparency of the IoT and IIoT, consistent design and development of their diverse augmented services is crucial for their wider acceptance as well as their safe and sustainable utilization.
Fault-tolerant control of a hydraulic servo actuator via adaptive dynamic programming
Authors: Stojanovic Vladimir
Published: September 2023

The fault-tolerant control problem of a hydraulic servo actuator in the presence of actuator faults is studied utilizing adaptive dynamic programming. This task is challenging because of unknown system dynamics, uncertain disturbances or unmeasurable system states of such highly nonlinear systems in real applications. The aim is to achieve asymptotic tracking and actuator faults compensation by minimizing some predefined performance index. The discrete-time algebraic Riccati equation is iteratively solved by the adaptive dynamic programming approach. For practical reasons, adaptive dynamic programming techniques and fault compensation are integrated to iteratively compute an approximated optimal fault-tolerant control using real-time input/output data without any a priori knowledge of the system dynamics and unmeasurable states. As a result, a fault-tolerant control of hydraulic servo actuator is then designed based on adaptive dynamic programming via output feedback. Also, the convergence analysis of a data-driven fault-tolerant control is theoretically shown as well. Finally, intensive simulation results are given to prove the validity and merits of the developed data-driven fault-tolerant control strategy.

This study designed and implemented a personal learning environment platform for spoken English teaching in a junior high school in China to improve students' spoken English narrative competence. Altogether, 83 junior high school year one students took part in this study. The participants were divided into experimental and control classes for the two-month-long experiment. The personal learning environment-based spoken English platform was implemented in the experimental class, while the control class used traditional face-to-face instruction. Pre- and post-spoken English tests and semistructured interviews were used in the study. The data analysis revealed that PLEs has the potential to boost students' learning motivation and enthusiasm and improve their spoken English narrative performance as well. This study advanced practical research of PLEs in junior high school and enhanced the theoretical research in spoken English teaching.
Factors Associated With Initiation of Mechanical Ventilation in Patients With Sepsis: Retrospective Observational Study
Authors: Freundlich Robert E. , Li Gen , Leis Aleda , Engoren Milo
Published: September 2023

Background

Patients with sepsis are at risk for mechanical ventilation. This study aimed to identify risk factors for initiation of mechanical ventilation in patients with sepsis and assess whether these factors varied with time.

Methods

Data from the electronic health record were used to model risk factors for initiation of mechanical ventilation after the onset of sepsis. A time-varying Cox model was used to study factors that varied with time.

Results

Of 35 020 patients who met sepsis criteria, 28 747 were eligible for inclusion. Mechanical ventilation was initiated within 30 days after sepsis onset in 3891 patients (13.5%). Factors that were independently associated with increased likelihood of receipt of mechanical ventilation were race (White: adjusted hazard ratio [HR], 1.59; 95% CI, 1.39-1.83; other/unknown: adjusted HR, 1.97; 95% CI, 1.54-2.52), systemic inflammatory response syndrome (adjusted HR [per point], 1.23; 95% CI, 1.17-1.28), Sequential Organ Failure Assessment score (adjusted HR [per point], 1.28; 95% CI, 1.26-1.31), and congestive heart failure (adjusted HR, 1.30; 95% CI, 1.17-1.45). Hazard ratios decreased with time for Sequential Organ Failure Assessment score and congestive heart failure and varied with time for 4 comorbidities and 3 culture results.

Conclusions

The risk for mechanical ventilation associated with different factors varied with time after sepsis onset, increasing for some factors and decreasing for others. Through a better understanding of risk factors for initiation of mechanical ventilation in patients with sepsis, targeted interventions may be tailored to high-risk patients.

The Renin Angiotensin Aldosterone System (RAAS) is the main regulator of body fluid and electrolyte balance in the human body. Features of RAAS activation, such as hypertension and fluid retention, are not apparent in some categories of CKD-like tubular interstitial diseases. The beneficial effects of RAAS blockers are controversial if not activated.  This study was conducted to identify the features of RAAS activation in CKDu and to evaluate the representativeness of Aldosterone as a marker of activation. A cross-sectional study was conducted on 119 definite CKDu patients at the renal clinics in Girandurukotte and Wilgamuwa, Sri Lanka. The basic biochemical parameters, serum electrolytes, and osmolality were measured by using serum and urine samples of the participants. Statistical analysis was performed in IBM SPSS statistics version 23. Only 4.4% and 6.7% of study subjects had increased serum Aldosterone and serum Angiotensin II. There was a significant positive correlation between serum Aldosterone with serum creatinine (r=0.477, p<0.01) and Angiotensin II (r=0.379, p<0.01). Inversely, it was negatively correlated with eGFR (r=-0.353, p<0.01). Moreover, serum aldosterone had a significant elevation in the late stages (p=0.024) than early stages and was significantly associated with proteinuria (p=0.032).  Results showed no indications of activated RAAS in patients with the diagnosis of definite CKDu. A significant number of the population had hypernatremia which is positively correlated with hyperosmolality, indicating dehydration.  The possibility of subclinical dehydration that may have an effect with faster progression.

Regulation 2017/625 allows and encourages the use of rating schemes as a means to increase transparency in the agri-food chain. Since its implementation, a need for greater fairness, consistency, transparency, and objectivity in official controls has been reported by member states. The present study compares the results of inspection activity concerning food hygiene principles in ethnic and traditional butcheries. The sample consists of 50 food business activities randomly selected from traditional and ethnic butcheries subject to official control in Turin from January to June 2019. Our two objectives were to evaluate the degree of awareness and training of food business operators (FBOs) and to compare the written records drawn up by the competent authorities (CAs) during official inspections to evaluate their completeness and uniformity. The presence of old equipment is a common finding in both traditional and ethnic butchers. This could lead to ineffective cleaning operations and inappropriate functioning, which in turn could lead to a dangerous loss of control over products’ temperatures. Ethnic butchers showed a higher number of non-compliances for documentary examination, the presence/correctness of self-control plans, and management aspects such as by-product disposal and personnel hygiene. Training is the key point for both CAs and FBOs; inspectors must maintain their professionalism but also adhere to harmonized and intellectually supported criteria, and FBOs must prevent improper behavior. Eventually, we propose strategies to increase the efficacy and homogeneity of records, together with suggestions on how to implement training both for consultants and operators.
Physical exercise in asthma adolescents: a concept review
Authors: Privitera Salvatore , Privitera Antonio
Published: September 2023

Asthma is a frequent pathological condition during childhood and adolescence. Young asthmatics demonstrate decreased aptitude for physical activity and a limited exercise capacity. Lower hospitalisation rates, reduced school absenteeism, fewer medical examinations, and limited use of bronchodilators have been documented in children and adolescents with bronchial asthma who engage in physical exercise regularly. Structured physical exercise protocols should be encouraged as they can work as a synergistic therapeutic option in addition to regular pharmacologic treatment. This article outlines the most suitable exercise training techniques for young patients with bronchial asthma and their effects on health status.

Background: The role of vitamin D in reducing the risk of falls in older adults has not been clearly demonstrated. This study examined the effectiveness of vitamin D supplementation in reducing the risk of falls in older adults.Methods: Four databases (Cochrane Library, Embase, PubMed, and CINAHL) were searched without language restrictions or time limitations. These articles were comprehensively screened using EndNote version 20.1 software. A manual search of the reference lists of the identified studies was also performed. The analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta–Analyses (PRISMA) guidelines. The pooled evidence was analyzed using RevMan software version 5.4.Results: Seventeen studies met inclusion criteria among 550 potentially relevant studies. The pooled analysis of 38,598 older adults showed that vitamin D supplementation decreased the odds of having at least one fall by 1% (odds ratio [OR]=1.01; 95% confidence interval [CI], 0.92–1.11; p=0.86); however, the difference was not statistically significant. Of eight studies with 19,946 older adults, the pooled analysis showed a 12% (OR=1.12; 95% CI, 0.97–1.29; p=0.11) decrease in the odds of having at least one fracture among older adults; however, the difference was also not statistically significant. Pooled subgroup analysis showed that neither low (<2,000 IU/day) nor high (≥2,000 and <4,000 IU/day) doses of vitamin D supplementation had any significant effect on the incidence of falls and fractures.Conclusion: Vitamin D supplementation had no beneficial effect in reducing fall and fracture incidence among older adults.
Use Cases for Communication Between Plug-in Vehicles and Off-Board DC Charger
Authors:   Hybrid - EV Committee
Published: September 2023

This SAE Information Report, SAE J2836-2, establishes use cases and general information for communication between plug-in electric vehicles (PEVs) and the DC off-board charger. Where relevant, this document notes, but does not formally specify, interactions between the vehicle and vehicle operator.

This applies to the off-board DC charger for conductive charging, which supplies DC current to the vehicle battery of the electric vehicle through a SAE J1772 hybrid coupler or SAE J1772 AC Level 2-type coupler on DC power lines, using the AC power lines or the pilot line for power line communication (PLC), or dedicated communication lines that are further described in SAE J2847-2.

The specification supports DC energy transfer via forward power flow (FPF) from grid-to-vehicle.

The relationship of this document to the others that address PEV communications is further explained in Section 5.
The applicability of the Polluter Pays Principle in the field of nuclear energy in the EU
Authors: Veuchelen Ludo
Published: September 2023

This article will examine whether the Polluter Pays Principle is formulated and applied in EU versus nuclear (Euratom) law and what consequences such application could have for the EU Member Countries, e.g., when deciding on new nuclear projects or life time extension of nuclear installations.

The ECJ had already clearly accepted the Polluter Pays Principle’s function of internalization of all environmental costs. It is crystal clear that EU Institutions are required to apply the PPP, together with the Precautionary and the Proportionality Principles. The application of the PPP in the nuclear field has been emphasized in an EU Commission Recommendation of 24 October 2006.

On the other hand, with Council Directive 2011/70/EURATOM of 19 July 2011, a Community framework for the responsible and safe management of spent fuel and radioactive waste was launched. In its Article 5(1) the duty to establish and maintain a national framework was formulated, but no mention is made of the application of the PPP, not in this Directive nor in the national reports and the EU follow up reports. The terminology used therein, ‘adequate financial resources’, falls short of an unambiguous adherence to the Polluter Pays Principle. The PPP should hold that ALL costs for decommissioning, waste conditioning and final disposal should be carried by the polluter. A cap on the nuclear waste costs as decided in Belgium seems to be in full contradiction with the earlier decisions of the ECJ and with the EU Commission’s Recommendation of 2006. Furthermore, the EU General Environmental Principles are made applicable to the nuclear energy sector by the ECJ in the Hinkley Point C case. As argued in the present article, the Polluter Pays Principle will be a heavy burden to bring the EU legal acquis in line with all the uncertainties on the costs of closing the cycle of nuclear energy production. Accepting a ‘cap’ on the nuclear waste costs leaves a blank cheque for later generations, which is not only against the Polluter Pays Principle, but is also completely in contradiction with the EU Green Deal regarding fair competition in the field of energy production and limiting the effect of subsidies for costs which have to be borne by the nuclear waste producers.
