description: We analyze quantum dot models used in current research for misconceptions that arise from the choice of basis states for the carriers. The examined models originate from semiconductor quantum optics, but the illustrated conceptional problems are not limited to this field. We demonstrate how the choice of basis states can imply a factorization scheme that leads to an artificial dependency between two, actually independent, quantities. Furthermore, we consider an open quantum dot-cavity system and show how the dephasing, generated by the dissipator in the von Neumann Lindblad equation, depends on the choice of basis states that are used to construct the collapse operators. We find that the Rabi oscillations of the s-shell exciton are either dephased by the dissipative decay of the p-shell exciton or remain unaffected, depending on the choice of basis states. In a last step we resolve this discrepancy by taking the full system-reservoir interaction Hamiltonian into account.

description: Given a connect sum of link diagrams, there is an isomorphism which decomposes unnormalized Khovanov chain groups for the product in terms of normalized chain groups for the factors; this isomorphism is straightforward to see on the level of chains. Similarly, any plumbing $x*y$ of Kauffman states carries an isomorphism of the chain subgroups generated by the enhancements of $x*y$, $x$, $y$: \[ \mathcal{C}_R(x*y)\to \left(\mathcal{C}_{R,p\to1}(x)\otimes \mathcal{C}_{R,p\to1}(y)\right)\oplus\left(\mathcal{C}_{R,p\to0}(x)\otimes \mathcal{C}_{R,p\to0}(y)\right). \] We apply this plumbing of chains to to prove that every homogeneously adequate state has enhancements $X^\pm$ in distinct $j$-gradings whose $A$-traces (which we define) represent nonzero Khovanov homology classes over $\mathbb{F}_2$, and that this is also true over $\mathbb{Z}$ when all $A$-blocks' state surfaces are two-sided. We construct $X^\pm$ explicitly.

description: We present LeJit, a template-based framework for testing Java just-in-time (JIT) compilers. Like recent template-based frameworks, LeJit executes a template -- a program with holes to be filled -- to generate concrete programs given as inputs to Java JIT compilers. LeJit automatically generates template programs from existing Java code by converting expressions to holes, as well as generating necessary glue code (i.e., code that generates instances of non-primitive types) to make generated templates executable. We have successfully used LeJit to test a range of popular Java JIT compilers, revealing five bugs in HotSpot, nine bugs in OpenJ9, and one bug in GraalVM. All of these bugs have been confirmed by Oracle and IBM developers, and 11 of these bugs were previously unknown, including two CVEs (Common Vulnerabilities and Exposures). Our comparison with several existing approaches shows that LeJit is complementary to them and is a powerful technique for ensuring Java JIT compiler correctness.

(CR47) Rare Case of Giant Left Frontal Mucocele Presenting 28 years After Frontal Bone Fracture: Case Report and Points in Surgical Management
Creators: name: Peng, Lee King
Publisher: name: Zenodo
Year: 2022

description: Giant mucocele of the frontal sinus is a rare pathology caused by retention of mucous secretions in the frontal sinus, which can expand and erode adjacent frontal and orbital bones and extend into intracranial and/or intraorbital compartment. Here, we describe a case of giant left frontal mucocele in a middle-aged gentleman with predisposing history of bifrontal craniotomy for severe brain injury with left frontal bone fracture 28 years ago. Imaging findings were suggestive of large expansile lobulated lesion arising from left frontal sinus with surrounding mass effect on adjacent frontal lobe and bone, extraocular muscle and globe with left fronto-orbital bony defect with foreign bodies. Bifrontal craniotomy, excision of mucocele, cranialization of frontal sinus, frontal bone reconstruction with split calvarial graft and fasciaduraplasty with was performed. Postoperatively, patient was extubated and reported no recurrence of lesion. This case demonstrates the importance of recognition of frontal mucocele as a possible long-standing complication of frontal bone fracture and the need for proper surgical management to prevent recurrence or infective complications.

description: We propose a new Riemannian gradient descent method for computing spherical area-preserving mappings of topological spheres using a Riemannian retraction-based framework with theoretically guaranteed convergence. The objective function is based on the stretch energy functional, and the minimization is constrained on a power manifold of unit spheres embedded in 3-dimensional Euclidean space. Numerical experiments on several mesh models demonstrate the accuracy and stability of the proposed framework. Comparisons with two existing state-of-the-art methods for computing area-preserving mappings demonstrate that our algorithm is both competitive and more efficient. Finally, we present a concrete application to the problem of landmark-aligned surface registration of two brain models.

description: ABSTRACT Introduction: Globally, governments and other funding bodies demand measurable returns for their investment which produce benefits beyond academia. Different methods of assessment, definitions of impact, inter-sectoral collaboration, costs, and time all have a bearing on successful evaluations of research impact. The aim of this paper is to review studies from a broad field of disciplines which report on research impact in the peer-reviewed literature. We will examine the characteristics and study design quality of publications that report research impact. This review will provide an insight in the extentd and type of research impact reported, and hopefully identify gaps in the existing literature. Methods and analysis: We will design a comprehensive search strategy in collaboration with an experienced librarian. The sources of peer-reviewed literature that will be searched include JCU One Search, Scopus, Web of Science, Emerald Insight, ProQuest, Sage Journals, Wiley, Informit, JSTOR, Academic OneFile, and Google Scholar. Author one will screen titles, abstracts and full-text articles, which will be cross-checked by author two. Data abstraction will be completed by author one and subsequently cross-checked by author two. We will create summary tables providing the characteristics of the included studies. Study design quality of included publications will be assessed according to The Critical Appraisal Skills Programme (CASP, 2017). Qualitative data will be coded in NVIVO, and synthesis performed through thematic analysis, presented in narrative form. Ethics and dissemination: Ethical approval is not required as our study will not include confidential data that can be linked to individuals. We will disseminate our results through a peer-reviewed publication.
(CR48) A Rare Presentation of Upper Airway Obstruction in Infancy with its Surgical Approach
Creators: name: Afiful Hadi
Publisher: name: Zenodo
Year: 2022

description: Introduction: Undiagnosed oropharyngeal teratomas that are present at birth are challenging to manage, especially in non-tertiary hospitals. Antenatal diagnosis of this disorder is crucial for proper planning for safe delivery as this mass may cause significant airway obstruction, leading to irreversible foetal morbidity and mortality. Case Presentation: We report a month-old baby boy who presented with progressive respiratory distress on day 7 of life and was hospitalised on day 15 due to a worsening of respiratory symptoms. Our examination showed a left oropharyngeal mass with obliteration of the pyriform fossa. Magnetic Resonance Imaging (MRI) confirmed the solid parapharyngeal mass with its epicentre at the oropharyngeal, which causes tracheal deviation to the contralateral side and narrowing of the oropharyngeal as well as hypopharyngeal diameter to 1.7cm. Transoral excision of the mass is done under general anaesthesia with uneventful postoperative recovery. Histopathology revealed a mature teratoma and 2 years of follow-up showed no recurrence. Conclusion: Teratomas in the head and neck are rare, accounting for 2–9% of all reported teratomas, and they are more uncommon in the oropharyngeal region. Although teratomas are benign tumours, they may be life-threatening because of their location. The rarity of it as the causes of upper airway obstruction in neonates may result in delayed diagnosis and this may result in difficulty during intubation if required. This case report brings forth the atypical clinical presentation and the chosen surgical approach in this infant versus the conventional transcervical approach, while also sharing our experience as a newly established paediatric otorhinolaryngology centre in Malaysia.

Halperin States of Particles and Holes in Ideal Time Reversal Invariant Pairs of Chern Bands and The Fractional Quantum Spin Hall Effect in Moiré MoTe$_2$

subject: FOS: Physical sciences

description: An experiment in moiré MoTe$_2$ bilayers reported the first observation of a topologically ordered state with zero Hall conductivity and half of the edge conductance of a standard time-reversal invariant quantum spin Hall insulator. This state is believed to emerge at total filling one of a pair of bands with Chern numbers $C=\pm1$ related by time reversal symmetry. By viewing these bands as a pair of Landau levels with opposite magnetic fields, and starting from a parent magnet with one filled band, we demonstrate that a class of Halperin states constructed by adding particles to the empty Chern band and holes to the occupied Chern band have all the properties observed in MoTe$_2$. Remarkably, these states break time-reversal symmetry but have exactly zero Hall conductivity and helical edge conductance of $e^2/2h$. These states also feature a spinless composite fermion with the same charge as the electron but split equally between both valleys. In a standard Halperin 331 state, this particle would be a neutral Bogoliubov composite fermion. However, in our context this composite fermion is charged but remains itinerant because it is split into the two valleys that effectively experience opposite magnetic fields. The existence of such charged itinerant particles is a key difference between Landau levels with opposite magnetic fields and standard multi-components Landau levels, where all the itinerant particles are charge neutral, such as the magneto-roton of the Laughlin state or the Bogoliubov composite fermion of the Moore-Read state. When the electron density changes away from the ideal filling and these itinerant charged particles are added to the parent state, the disorder potential is less efficient at localizing them as compared to standard Lanadau levels. This can explain why the state in MoTe$_2$ did not display a robust Hall plateau upon changing the electron density.

description: The aim of the study was to systematically explore the relationships between various adipokines and risks of endometrial atypical hyperplasia (EAH), type I endometrial cancer (EC), and type II EC. We enrolled 219 patients in this study, including 39 EAH, 87 type I EC, 38 type II EC and 55 control individuals. We subsequently explored the association of adipokine levels and the leptin-to-adiponectin (L/A) ratio with EAH, type I EC, and type II EC. The plasma leptin level and L/A ratio were significantly higher in the EAH group than in the control group (p = 0.012). Leptin, resistin, vaspin, and visfatin levels were significantly higher in the type I EC group; however, the adiponectin level was lower in the type I EC, which resulted in a higher L/A ratio. Notably, the L/A ratio and visfatin level in the type II EC group were significantly higher. Multiple logistic regression analysis revealed that a higher leptin level was significantly associated with a higher EAH risk (p = 0.012). Higher leptin level (p = 0.042) and L/A ratio (p = 0.027) were significantly associated with an increased type I EC risk. By contrast, higher leptin (p = 0.059) and visfatin (p = 0.003) levels, higher L/A ratio (p = 0.033), and lower adiponectin level (p = 0.042) were associated with an increased type II EC risk. We suggested that adipokines are potentially correlated with EAH and EC risks. What is already known on this subject? EAH and EC are considered significantly correlated with obesity and the related insulin resistance. Studies reported that some of the adipokines mediate obesity-related EC risk. What do the results of this study add? We systematically explored whether the adipokines produced from adipose tissue, including leptin, adiponectin, resistin, vaspin, and visfatin as well as the L/A ratio were associated with increased EAH, type I EC, and type II EC risks; whether they are independent risk factors for EAH and EC. Moreover, we analysed the underlying roles of these adipokines in EC tumorigenesis and development. What are the implications of these findings for clinical practice and/or further research? This study aimed to systematically explore the relationships between various adipokines and risks of EAH, type I EC, and type II EC, to suggest that adipokine levels correlated with EAH and EC risks, and to analyse the underlying molecular mechanisms linking adipokines with endometrial carcinogenesis. It is helpful to improve our understanding of EC tumorigenesis and development.

description: Population annealing is a hybrid of sequential and Markov chain Monte Carlo methods geared towards the efficient parallel simulation of systems with complex free-energy landscapes. Systems with first-order phase transitions are among the problems in computational physics that are difficult to tackle with standard methods such as local-update simulations in the canonical ensemble, for example with the Metropolis algorithm. It is hence interesting to see whether such transitions can be more easily studied using population annealing. We report here our preliminary observations from population annealing runs for the two-dimensional Potts model with $q > 4$, where it undergoes a first-order transition.

description: Detection and molecular characterization of Chikungunya and Zika in a dengue endemic region of the Peruvian coast

   ABSTRACT Background: Arboviral diseases has reemerged in the last years affecting primarily the coast of Peru. Piura is an endemic region of Dengue, where the recent appearance of Chikungunya (CHIKV) and Zika (ZIKV) has been renewed. Aim: To assess the presence of DENV, CHIKV, and ZIKV in serum samples of patients with acute febrile illness in a locality ofPiura, Peru and describe associated clinical features. Methodology: Descriptive cross-sectional study, sampling was done for convenience where it was obtained atotal of 496 serum samples from patients with acute febrile illness were collected from 18 primary care centers. All samples were analyzed via real-time RT-PCR to detect DENV, CHIKV, and ZIKV. In addition, positive samples for DENV were also processed for serotypes 1 to 4 classification via RT-PCR. Results: DENV was the most common arbovirus detected in 170/496 (34.3%), followed by ZIKV in 39/496 (7.9%) and CHIKV in 23/496 (4.6%). Among the 170 samples positive for DENV, serotype 2 was the most predominant type present in 97/170 (57.1%) of samples, followed by the serotype 3 in 9/170 (5.3%). Headaches, muscle pain, and joint pain were the most common symptoms associated with fever in patients with DENV and ZIKV. No symptoms predominance was observed in patients with CHIKV. Conclusions: DENV is considered the most frequent arbovirus in Peru and the number of cases has increased dramatically in the last 5 years. However, it is not the only arbovirus that circulates along the northern coast of Peru. It has also been determined the presence of ZIKV and CHIKV in our population, which may suggest the circulation of other arboviruses that have not been detected.

Characteristic Properties of Two Different Viscous Cosmology Models for the Future Universe

description: We analyze characteristic properties of two different cosmological models: (i) a one-component dark energy model where the bulk viscosity $ζ$ is associated with the fluid as a whole, and (ii) a two-component model where $ζ$ is associated with a dark matter component $ρ_{\rm m}$ only, the dark energy component considered inviscid. Shear viscosity is omitted. We assume throughout the simple equation of state $p=wρ$, with $w$ a constant. In the one-component model we consider two possibilities, either to take $ζ$ proportional to the scalar expansion (equivalent to the Hubble parameter), in which case the evolution becomes critically dependent on the value of the small constant $α=1+w$ and the magnitude of $ζ$. Second, we consider the case $ζ=~$const., where a de Sitter final stage is reached in the future. In the two-component model we consider only the case where the dark matter viscosity $ζ_{\rm m}$ is proportional to the square of $ρ_{\rm m}$, where again a de Sitter form is found in the future. In this latter case the formalism is supplemented by a phase space analysis. As a general result of our considerations we suggest that a value $ζ_0\sim 10^6~$Pa s for the present viscosity is reasonable, and that the two-component model seems to be favored.

description: Click-through rate (CTR) prediction is a crucial area of research in online advertising. While binary cross entropy (BCE) has been widely used as the optimization objective for treating CTR prediction as a binary classification problem, recent advancements have shown that combining BCE loss with an auxiliary ranking loss can significantly improve performance. However, the full effectiveness of this combination loss is not yet fully understood. In this paper, we uncover a new challenge associated with the BCE loss in scenarios where positive feedback is sparse: the issue of gradient vanishing for negative samples. We introduce a novel perspective on the effectiveness of the auxiliary ranking loss in CTR prediction: it generates larger gradients on negative samples, thereby mitigating the optimization difficulties when using the BCE loss only and resulting in improved classification ability. To validate our perspective, we conduct theoretical analysis and extensive empirical evaluations on public datasets. Additionally, we successfully integrate the ranking loss into Tencent's online advertising system, achieving notable lifts of 0.70% and 1.26% in Gross Merchandise Value (GMV) for two main scenarios.

description: We analyze the lepton number violating (LNV) meson decays that arise in a TeV scale Left Right Symmetry model. The right handed Majorana neutrino $N$ along with the right handed or Standard Model gauge bosons mediate the meson decays and provide a resonant enhancement of the rates if the mass of $N$ ($M_N$) lies in the range $\sim (100\, \rm{MeV}-5\, \rm{GeV})$. Using the expected upper limits on the number of events for the LNV decay modes $M_{1}^{+} \to\ell^{+}\ell^{+}π^{-}$~($M_{1}=B, D, D_{s}, K$), we derive constraints plausible on the mass of the right handed charged gauge boson by future searches at the ongoing NA62 and LHCb experiments at CERN, the upcoming Belle II at SuperKEK, as well as at the proposed future experiments, SHiP and FCC-ee. These bounds are complimentary to the limits from same-sign dilepton search at Large Hadron Collider (LHC). The very high intensity of Charmed mesons expected to be produced at SHiP will result in a far more stringent bound, $M_{W_R}>18.4$~TeV (corresponding to $M_N=1.46$~GeV), than the other existing bounds from collider and neutrinoless double beta decay searches.

description: With the introduction of ChatGPT, Large Language Models (LLMs) have received enormous attention in healthcare. Despite their potential benefits, researchers have underscored various ethical implications. While individual instances have drawn much attention, the debate lacks a systematic overview of practical applications currently researched and ethical issues connected to them. Against this background, this work aims to map the ethical landscape surrounding the current stage of deployment of LLMs in medicine and healthcare. Electronic databases and preprint servers were queried using a comprehensive search strategy. Studies were screened and extracted following a modified rapid review approach. Methodological quality was assessed using a hybrid approach. For 53 records, a meta-aggregative synthesis was performed. Four fields of applications emerged and testify to a vivid exploration phase. Advantages of using LLMs are attributed to their capacity in data analysis, personalized information provisioning, support in decision-making, mitigating information loss and enhancing information accessibility. However, we also identifies recurrent ethical concerns connected to fairness, bias, non-maleficence, transparency, and privacy. A distinctive concern is the tendency to produce harmful misinformation or convincingly but inaccurate content. A recurrent plea for ethical guidance and human oversight is evident. Given the variety of use cases, it is suggested that the ethical guidance debate be reframed to focus on defining what constitutes acceptable human oversight across the spectrum of applications. This involves considering diverse settings, varying potentials for harm, and different acceptable thresholds for performance and certainty in healthcare. In addition, a critical inquiry is necessary to determine the extent to which the current experimental use of LLMs is necessary and justified.

description: Unidentified Anomalous Phenomena (UAP), also known as Unidentified Flying Objects (UFOs), has shifted from being a stigmatized topic on the fringes of scientific inquiry to a legitimate subject of scientific interest with a need for high quality, curated data, and rigorous scientific investigation. This paper presents a preliminary scoping review and analysis of scholarly literature related to UAP from 1967 until 2023, exploring a diverse range of research areas across disciplines to illustrate scholarly discourse about the topic. The paper focuses on characterizing papers published in recent years and notes that Library & Information Science is unrepresented in the current UAP literature. The paper also discusses how researchers across the iFields can contribute to UAP studies through inherent expertise such as data curation and data science as well as information behavior and information literacy, among others. The paper concludes by emphasizing that UAP Studies offer a rich intellectual realm for information science research, with the iFields well positioned to play a crucial role in supporting and engaging in the study of UAP.

description: The control of spins and spin to charge conversion in organics requires understanding the molecular spin-orbit coupling (SOC), and a means to tune its strength. However, quantifying SOC strengths indirectly through spin relaxation effects has proven diffi- cult due to competing relaxation mechanisms. Here we present a systematic study of the g-tensor shift in molecular semiconductors and link it directly to the SOC strength in a series of high mobility molecular semiconductors with strong potential for future devices. The results demonstrate a rich variability of the molecular g-shifts with the effective SOC, depending on subtle aspects of molecular composition and structure. We correlate the above g -shifts to spin-lattice relaxation times over four orders of magnitude, from 200 μs to 0.15 μs, for isolated molecules in solution and relate our findings for isolated molecules in solution to the spin relaxation mechanisms that are likely to be relevant in solid state systems.

Two dystopic visions on the relationship of humans and progress – Emile Souvestre and Cordwainer Smith

description: Abstract Zaha Hadid’s statement that is used as an epigraph to this book is also the cornerstone of this essay: “Non puo esserci progresso senza affrontare l’ignoto”. This sentence has an ambiguous meaning and can be interpreted in at least two different ways: either as a natural challenge or as an aggressive defiance. This ambiguity encompasses the relationship between individuals, communities and progress, reminding the image of Janus, each facing a different side, both forming the same and a different entity. It is a natural and complementary ambivalence. Every endeavour undertook by promoters of progress has a degree of uncertainty, a pending threat of failure, and the outcome always produces positive and negative consequences frequently in uneven ways. Culturally, in a consistent way at least from the beginning of modernity, Western civilisation has regarded progress as a natural unstoppable endeavour. Sometimes even as a duty of every rational educated person – to pass (or trespass) the frontier of the known, to act, to evolve, to transform, to change, and to discover the “God given world”. This almost linear way to understand progress, to view reality from a dominant, sometimes exclusive point of view, tends to erase the notion and effects of negative consequences both on individuals and on communities, assumed by the dominant culture as acceptable collateral damages in the name/notion of rational evolution. In this essay, the main goal is to defy this dominant trend of evolution as based mainly on material, objective, rational progress, and defy the unique view of a future based on quantifiable and technological evolution. This challenge will be done with the comparative analysis of two literary texts: Emile Souvestre’s Le monde tel qu'il sera and Cordwainer Smith’s “Alpha Ralpha Boulevard”.

The Interplay of Learning, Analytics, and Artificial Intelligence in Education: A Vision for Hybrid Intelligence

description: This paper presents a multi-dimensional view of AI's role in learning and education, emphasizing the intricate interplay between AI, analytics, and the learning processes. Here, I challenge the prevalent narrow conceptualisation of AI as tools, as exemplified in generative AI tools, and argue for the importance of alternative conceptualisations of AI for achieving human-AI hybrid intelligence. I highlight the differences between human intelligence and artificial information processing, the importance of hybrid human-AI systems to extend human cognition, and posit that AI can also serve as an instrument for understanding human learning. Early learning sciences and AI in Education research (AIED), which saw AI as an analogy for human intelligence, have diverged from this perspective, prompting a need to rekindle this connection. The paper presents three unique conceptualisations of AI: the externalization of human cognition, the internalization of AI models to influence human mental models, and the extension of human cognition via tightly coupled human-AI hybrid intelligence systems. Examples from current research and practice are examined as instances of the three conceptualisations in education, highlighting the potential value and limitations of each conceptualisation for education, as well as the perils of overemphasis on externalising human cognition. The paper concludes with advocacy for a broader approach to AIED that goes beyond considerations on the design and development of AI, but also includes educating people about AI and innovating educational systems to remain relevant in an AI-ubiquitous world.

description: Disruptions in hot cognition, i.e., the processing of emotionally salient information, are prevalent in most neuropsychiatric disorders and constitute a potential treatment target. EMOTICOM is the first comprehensive neuropsychological test battery developed specifically to assess hot cognition. The aim of the study was to validate and establish a Danish language version and reference data for the EMOTICOM test battery. To evaluate the psychometric properties of 11 EMOTICOM tasks, we collected data from 100 healthy Danish participants (50 males, 50 females) including retest data from 49 participants. We assessed test-retest reliability, floor and ceiling effects, task-intercorrelations, and correlations between task performance and relevant demographic and descriptive factors. We found that test-retest reliability varied from poor to excellent while some tasks exhibited floor or ceiling effects. Intercorrelations among EMOTICOM task outcomes were low, indicating that the tasks capture different cognitive constructs. EMOTICOM task performance was largely independent of age, sex, education, and IQ as well as current mood, personality, and self-reported motivation and diligence during task completion. Overall, many of the EMOTICOM tasks were found to be useful and objective measures of hot cognition although select tasks may benefit from modifications to avoid floor and ceiling effects in healthy individuals.
