Quantum-dot cellular automata serial decimal digit multiplier
Authors: Gladshtein Michael 
Published: February 2025

Abstract
The quantum-dot cellular automata (QCA) technology is considered as a possible nanoelectronic technology for future computing facilities. The leading role of QCA wires makes it preferable for serial data transfer/processing. Many modern computer applications require direct processing of decimal information without representation and conversion errors. The main purpose of the research is to design a novel QCA serial decimal digit multiplier. A QCA wire can be considered as a virtual tape with written binary symbols. The designed multiplier uses the Turing machine run-time multiple tapes reconfiguration to multiply two decimal digits encoded in the 5-bit Johnson–Mobius code. The proposed multiplier has successfully passed verification. In comparison with possible QCA BCD multipliers, it shows significant hardware simplification.

Abstract
Traumatic brain injury (TBI) can have a multitude of effects on neural functioning. In extreme cases, TBI can lead to seizures both immediately following the injury as well as persistent epilepsy over years to a lifetime. However, mechanisms of neural dysfunctioning after TBI remain poorly understood. To address these questions, we analyzed human and animal data and we developed a biophysical network model implementing effects of ion concentration dynamics and homeostatic synaptic plasticity to test effects of TBI on the brain network dynamics. We focus on three primary phenomena that have been reported in vivo after TBI: an increase in infra slow oscillations (<0.1 Hz), increase in Delta power (1 - 4 Hz), and the emergence of broadband Gamma bursts (30 - 100 Hz). Using computational network model, we show that the infra slow oscillations can be directly attributed to extracellular potassium dynamics, while the increase in Delta power and occurrence of Gamma bursts are related to the increase in strength of synaptic weights from homeostatic synaptic scaling triggered by trauma. We also show that the buildup of Gamma bursts in the injured region can lead to seizure-like events that propagate across the entire network; seizures can then be initiated in previously healthy regions. This study brings greater understanding of the network effects of TBI and how they can lead to epileptic activity. This lays the foundation to begin investigating how injured networks can be healed and seizures prevented.

Abstract

Introduction
Managing atrial fibrillation in kidney transplant patients poses a challenge for both nephrologists and cardiologists. Data regarding the safety and efficacy of catheter ablation in this patient’s cohort is scarce.

Methods and results
In this two-center prospective study, we included all consecutive kidney transplant patients who underwent atrial fibrillation ablation between April 2017 and March 2022. A 1:3 propensity score matching created a control group of non-transplant AF patients undergoing ablation. We included 16 kidney transplant patients and 48 matched controls. Ablation was successful in all patients. The periprocedural complication rate (6.3% in the kidney transplant group vs. 6.3% in the control group, p value = 1) did not differ between the two groups. One transplant patient experienced graft dysfunction after a complication. At 18 months, AF recurrence-fee rates were 69% in the transplant group and 70.1% in controls (p = 0.95). By the last follow-up, all transplant patients had discontinued antiarrhythmic drugs, while 19.6% of the patients in the control group were treated with antiarrhythmic drugs (p = 0.09). Kidney function in the transplant group remained stable (eGFR 32 [23.8, 40.5] ml/min/1.73 m2 before vs. 34 [29.8, 38] ml/min/1.73 m2 at last follow up, p = 0.93).

Conclusions
This study demonstrates that catheter ablation is a viable option for treating AF in kidney transplant patients, with comparable outcomes to non-transplanted individuals. Discontinuing antiarrhythmic drugs reduces drug interaction risks, but minimizing procedural complications remains critical to preserving graft function.

Intramodal consistency in triplet-based cross-modal learning for image retrieval
Authors: Mallea Mario , Ñanculef Ricardo , Araya Mauricio 
Published: February 2025

Abstract
Cross-modal retrieval requires building a common latent space that captures and correlates information from different data modalities, usually images and texts. Cross-modal training based on the triplet loss with hard negative mining is a state-of-the-art technique to address this problem. This paper shows that such approach is not always effective in handling intra-modal similarities. Specifically, we found that this method can lead to inconsistent similarity orderings in the latent space, where intra-modal pairs with unknown ground-truth similarity are ranked higher than cross-modal pairs representing the same concept. To address this problem, we propose two novel loss functions that leverage intra-modal similarity constraints available in a training triplet but not used by the original formulation. Additionally, this paper explores the application of this framework to unsupervised image retrieval problems, where cross-modal training can provide the supervisory signals that are otherwise missing in the absence of category labels. Up to our knowledge, we are the first to evaluate cross-modal training for intra-modal retrieval without labels. We present comprehensive experiments on MS-COCO and Flickr30k, demonstrating the advantages and limitations of the proposed methods in cross-modal and intra-modal retrieval tasks in terms of performance and novelty measures. We also conduct a case study on the ROCO dataset to assess the performance of our method on medical images and present an ablation study on one of our approaches to understanding the impact of the different components of the proposed loss function. Our code is publicly available on GitHub https://github.com/MariodotR/FullHN.git.
The prosody of the extended VP
Authors: Brodkin Dan 
Published: February 2025

Abstract
This paper investigates the syntax of vso and vos clauses in Mandar (Austronesian) by leveraging the prosody. This language allows free alternations between vso and vos orders, but phonotactic diagnostics reveal that vso strings are optimally parsed into tight prosodic constituents while vos strings are not. These results converge with syntactic diagnostics to show that vso orders arise from leftward movement of the verb while vos orders are generated through an additional step of rightward "Equation missing"-scrambling of the s. Targeted manipulations then reveal that phonological phrases can be built around substrings of arguments in the vso string, providing a new type of evidence for fine functional structure in the extended vp (Larson 1988). The prosodic parse of scrambled arguments, finally, shows that "Equation missing"-scrambling places its targets in adjunct positions (Chomsky 1993) in Mandar, setting up an account of scrambling that is grounded in the principle of Greed (Lasnik 1995).
Assessing SDN Controller Vulnerabilities: A Survey on Attack Typologies, Detection Mechanisms, Controller Selection, and Dataset Application in Machine Learning

Published: February 2025

Abstract
SDN controllers become the main advantage of the architecture because they present a centralized control decision-making and general view of the network. They are, however, also a critical point that an attacker could exploit. More review of the body of research is needed regarding the types of attacks on SDN controllers, methods to detect them, and mitigation techniques directed specifically to the controller, particularly considering the approach of machine learning detection methods. This survey addresses the topics of attacks targeting the SDN controller, methods for their detection, what types of controllers are used in different studies, and datasets used in machine learning detection methods. The findings highlight that most attacks exploit vulnerabilities inherent in the OpenFlow protocol, while the detection methodologies remain primarily statistical and machine learning approaches. Additionally, the review shows that while outdated controllers like Floodlight and Ryu are still widely used in studies, actively supported controllers such as ONOS and ODL are used much less. Finally, the survey finds only two publicly available datasets tailored for SDN environments, none considering attacks directed at the controllers, illustrating a notable gap in the existing research. This survey also highlights the need for further research focusing on modern SDN controllers and developing comprehensive datasets to advance effective security solutions.

Published: February 2025

Zusammenfassung
Corona (COVID-19, „coronavirus disease 2019“) kann die Arbeitsfähigkeit langfristig bedrohen. Die Erkenntnisse zum Einfluss von Long- bzw. Post-COVID auf die Arbeitsfähigkeit sind begrenzt und heterogen. Dieser Beitrag untersucht anhand qualitativer Daten die Lebens- und Arbeitssituation von Betroffenen nach ihrer COVID-19-Rehabilitation und zeigt die Besonderheiten der Zielgruppe sowie daraus resultierende Herausforderungen für Rehabilitation bzw. Berufstätigkeit auf. Wir führten Interviews mit COVID-19-Betroffenen (n = 15) 12 Monate nach ihrem Aufenthalt in der medizinischen Rehabilitation (kardiologisch, pneumologisch, neurologisch). Die Rekrutierung erfolgte mittels „maximum variation sampling“. Zudem erfolgten Interviews (n = 5) und Gruppendiskussionen (n = 3) mit Klinikmitarbeitenden. Alle Gespräche wurden auditiv aufgezeichnet, transkribiert und inhaltsanalytisch ausgewertet. Klinikmitarbeitende und Rehabilitand*innen verfolgen die Arbeitsfähigkeit als zentrales Ziel. Motivation wird aus der Wiedererlangung des Selbstwertgefühls, sozialer Integration sowie aus finanziellen Sorgen und Existenzängsten geschöpft. Die Aufrechterhaltung der Arbeitsfähigkeit erfolgt oft zulasten außerberuflicher Tätigkeiten. Um trotz Beeinträchtigungen arbeiten zu können, werden Kompensationsstrategien entwickelt. Unzureichend erscheint die sozialmedizinische Leistungsbeurteilung, die derzeit keine langfristigen Prognosen bzgl. der Arbeitsfähigkeit zulässt. Nach einer Rehabilitation kehren viele zur Arbeit zurück, für einige Betroffene bleiben die Folgen der COVID-19-Erkrankung jedoch eine langfristige berufliche Bedrohung. Die Erfassung und Beobachtung der Arbeitsfähigkeit und Stabilität der Arbeitssituation sind wichtig, um genaue sozialmedizinische Prognosen zu ermöglichen.

Abstract

Objective
To elucidate the regulatory mechanism of circRNAs in diabetic retinopathy.

Methods
Next-generation sequencing (NGS) was employed to identify circRNAs that are abnormally expressed in endothelial progenitor cells (EPCs) under hyperglycemia (HG) conditions. The regulatory mechanism and predicted targets of this circRNA were also studied via bioinformatics analysis, luciferase reporter assays, angiogenic differentiation experiments, flow cytometry, and RT-qPCR.

Results
Circ-astrotactin 1 (circ-Astn1) expression was decreased in EPCs under HG conditions, and circ-Astn1 overexpression inhibited HG-induced endothelial damage. The miR-138-5p and silencing information regulator 2 related enzyme 1 (SIRT1) were identified as circ-Astn1 downstream targets, which were further verified through luciferase reporter assays. SIRT1 silencing or miR-138-5p overexpression reversed the protective effect of circ-Astn1 on HG-induced endothelial cell dysfunction, as evidenced by increased apoptosis, abnormal vascular differentiation, and inflammatory factor secretion. SIRT1 overexpression reversed miR-138-5p-induced endothelial cell dysfunction under HG conditions. In vivo experiments confirmed that circ-Astn1 overexpression promoted skin wound healing through the regulation of SIRT1.

Conclusions
These findings suggest that circ-Astn1 promotes SIRT1 expression by sponging miR-138-5p. Circ-Astn1 overexpression suppresses HG-induced endothelial cell damage via miR-138-5p/SIRT1 axis.

Abstract
The environmental footprint of the aluminum industry is affected by greenhouse gas emissions and the amount of waste generated. Spent potlining (SPL) has traditionally been deposited, but increasing scrutiny is put to this practice. The cost of deposit is also increasing. First cut SPL is the carbon rich part and are the remaining cathode at end-of-life of an aluminum cell. A method for cleaning the first cut SPL is proposed which involves high temperature and low-pressure treatment for removal of fluoride-rich electrolyte remains. This way the carbon rich part of the SPL can become a product which can be reused or secondly used as an energy source, instead of being deposited. 5–19 kg of SPL has been treated for four hours in a furnace at low pressure and high temperature, and a post-treatment carbon purity up to 98 wt pct was found. The electrolyte condensate mainly consists of NaF og Na3AlF6. An LCA study on the process related to Norwegian aluminum smelters has been performed and the distance to the SPL treatment plant, the energy used during treatment and the SPL pre-processing, was found to affect the sustainability of such an industrial process the most.

Abstract
Ni-Cr-B-Si hardfaced coating is used in many mating components of Fast Breeder Reactors for improving their tribological properties. Selection of environment and load, plays a vital role in controlling wear loss of the hardfaced coating under rubbing conditions, in addition to its processing route. In the present study, a defect-free Ni-Cr-B-Si coating is made on 316L (N) stainless steel using Plasma Transferred Arc Welding (PTAW) process. Dominant phases dispersed in the γ-Ni matrix of the coating are identified to be borides (CrB, Cr5B3 and Cr3 B4), carbides (Cr23C6, Fe3C and Cr7C3) and nitride (BN). Average hardness of the coating is measured to be 536 ± 33 HV for 0.5 kg load. Tribological behavior of the coating is studied using a ball-on-disk tribometer at 2N and 5N loads in air (1 bar) and vacuum (10−9 bar), in order to simulate its friction and wear performance at contact pressures relevant for various structural components placed in a sodium environment. Results revealed higher average friction coefficient in vacuum than that in air, which is due to variation in dominant wear mechanism from tribo-oxidation to micro-plowing. Specific wear rate increased with both increase in load from 2 to 5N and change in environment from air to vacuum. This is attributed to the increased delamination-type wear along with oxidation in air and micro-plowing in vacuum as revealed by the unique tribo-induced morphology and chemistry corresponding to each of the wear test conditions. Techniques such as scanning electron microscopy, energy-dispersive spectroscopy, and Raman spectroscopy are used for the examination of tribo-pair surfaces, the results of which helped to elucidate the possible wear mechanisms. Results from the present study necessitate the relevance of choosing a hardfaced coating with appropriate microstructural and tribological characteristics for an intended application in order to minimize the risk of wear.
Is it Genocide?
Authors: James Paul 
Published: February 2025

Abstract
In the context of the current war, the question “Is the Israeli state effecting genocide in Gaza?” suggests a threshold legal excursus, a definitional contestation, or a cry of moral outrage. This article does not take any of those paths. It lives the pain of the unethical deaths of tens of thousands of civilians in Gaza, while beginning the longer-term task of seeking a way beyond deploying the concept of “genocide” as a performative gesture of shock and horror. The article argues that the meaning of genocide is being emptied out by an unsettling of the grounding conditions of political debate and the relativization of political language. While the evidence is strong that crimes against humanity are being perpetrated in Gaza, both by the Israeli state in its attack upon civilians and by Hamas in holding hostages, the provisional ruling by the International Court of Justice that there is a case to be answered is the most resolute that we can be at this point. Clearly, the war has to stop. In the meantime, the article suggests an alternative way of naming the horror.
Family diagnosis and paleogeography extended by asymmetrically deformed burmite liberiblattinid
Authors: Vršanský Peter 
Published: February 2025

Abstract
In total, 97 species and over 4,000 specimens of cockroaches are known from the tropical Upper Cretaceous burmite. This paper describes a new North Myanmar amber cockroach belonging to the ecologically diverse Mesozoic family Liberiblattinidae Vršanský, 2002, along with a summarization of its palaeogeographic distributions over geologic time, cosmopolitan during Upper Jurassic and Early Cretaceous. Compostus supremus gen. et sp. n. resembles genera Stavba Vršanská et Vršanský in Vršanský et al. (2019) and Facioblatta Hinkelman, 2023, and autapomorphies (forewing membrane coloration, monstrous sponging palps, carved hind leg) justify unique feeding and/or reproductive behaviors. Besides asymmetries (foretarsi non-taphonomic L/R difference 171%), the holotype specimen reveals mutations extremely rare in burmite.

Ausgehend von dem Befund einer institutionellen Unsichtbarkeit von Kindern im Kinderschutz und Evidenzen dafür, dass auf Offenbarungsversuche von Kindern nicht unterstützend reagiert wird, wird eine organisationssoziologische Deutung von Stimme und Schweigen betroffener Kinder angeboten. Entsprechend ist das Schweigen, etwa das Ausbleiben von Beschwerden oder auch das fehlende Anzeigen von Fehlverhalten, ein Warnsignal für einen Rückzug der Kinder, die in den Institutionen des Kinderschutzes keine unterstützenden Interaktionspartner_innen finden.
Sexuality Construction, Pornography, and Gender Violence: A Qualitative Study with Spanish Adolescents
Authors: Navarro-Mantas L. , Sáez-Lumbreras A. 
Published: February 2025

Abstract
Sexuality is a central aspect of human beings, and adolescence is a crucial period of transition from childhood to adulthood where sexual awakening occurs. As a critical aspect of life, adolescents should have quality sexual education to guide them through this transition. However, currently, educational institutions often lack structured and standardized sexual education programs that go beyond medicalized models focused on sexual and reproductive health and contraceptive use. A qualitative design using in-depth interviews with an ethnographic perspective to obtain detailed information considering the context. The Venegas model on sexual-affective education was referenced. This model identifies four significant areas: gender, sexuality, love/affection, and body. A qualitative design based on in-depth interviews was chosen to obtain detailed information about the issues mentioned. Forty semi-structured interviews were conducted with adolescents aged 13 to 20 in two groups: students of compulsory secondary education and vocational training. Results showed boys tend to prioritize physical aspects of sexuality, such as masturbation and intercourse, whereas girls tend to focus more on emotional connections and concern about contraception. Pornography, patriarchal cultural patterns, sexism, and traditional gender roles shaped these initial experiences. Meanings and practices were revealed to be conditioned by a sexist model of attraction, body dissatisfaction, and learning through pornography, which was related to experiences of normalized control and sexual violence in relationships. Some positive advancements resulting from feminist achievements were also discovered, such as understanding the value of consent, empathy, and the appreciation of alternative models of masculinity by some girls. These results highlight the importance of developing sexual education programs from a psychosocial and feminist perspective. Such programs should aim to transform cultural norms and attitudes surrounding sexuality, promoting agency and healthier and more equitable relationships among adolescents.
