Minor-monotone graph invariants.

In this paper, all graphs are undirected, loopless and without multiple edges. A minor of a graph arises by a series of deletions and contractions of edges and deletions of isolated vertices, suppressing any multiple edges and loops that may arise. The interest in minor-monotone graph parameters is activated because the Robertson-Seymour theory of graph minors can be applied to them. Recently a number of minor-monotone parameters have been studied, motivated in particular by the graph parameter μ(G) introduced by Colin de Verdiere [5] (cf. [6]). The parameter μ( G) can be described in terms of properties of matrices related to G. It was motivated by the study of the maximum multiplicity of the second eigenvalue of certain Schrodinger operators. When such an operator is defined on a Riemann surface, one can approximate the surface by a densely enough embedded graph G, in such a way that μ(G) is the maximum multiplicity of the second eigenvalue of the operator. The interest raised by Colin de Verdiere's parameter can be explained not only by its background in differential geometry, but also by the facts that it is minor-monotone (so that the Robertson-Seymour graph minors theory applies to it), and that it characterizes planarity of graphs. Indeed, one has that μ(G):::::; 3 if and only if G is planar. Moreover, as follows from the results in [19] and [15], μ(G) :::::; 4 if and only if G is linklessly embeddable in R.3 . (A graph G is linklessly embeddable if it can be embedded in R.3 in such a way that the images of any two disjoint circuits in G are unlinked.) So with the help of μ, topological properties of a graph can be characterized in terms of spectral properties of matrices associated to the graph. In this paper we give a survey of the graph parameter μ(G), and some related parameters, in particular the parameter >. ( G) introduced in [12]. We first give an overview of μ(G) and . \(G), after which we give proofs of a number of results. Finally, we consider the parameters X(G) (defined by oriented matroids) and "'(G).
Filtered lattice homology of curve singularities

Let $(C,o)$ be a complex analytic isolated curve singularity of arbitrary large embedded dimension. Its lattice cohomology ${\mathbb H}^*=\oplus_{q\geq 0}{\mathbb H}^q$ was introduced by \'Agoston and the author, each ${\mathbb H}^q$ is a graded ${\mathbb Z}[U]$--module. Here we study its homological version ${\mathbb H}_*(C,o)=\oplus_{q\geq 0}{\mathbb H}_q$. The construction uses the multivariable Hilbert function associated with the valuations provided by the normalization of the curve. A key intermediate product is a tower of spaces $\{S_n\}_{n\in {\mathbb Z}}$ such that ${\mathbb H}_q=\oplus_n H_q(S_n,{\mathbb Z})$. In this article for every $n$ we consider a natural filtration of the space $S_n$, which provides a homological spectral sequence converging to the homogeneous summand $H_q(S_n,{\mathbb Z})$ of the lattice homology. All the entries of all the pages of the spectral sequences are new invariants of $(C,o)$. We show how the collection of the first pages is equivalent with the motivic Poincar\'e series of $(C,o)$. We provide several concrete computations of the corresponding multivariable Poincar\'e series associated with the entries of the spectral sequences. In the case of plane curve singularities, the first page can also be identified with the Heegaard Floer Link homology of the link of the singularity. In this way, the new invariants provide for an arbitrary (non necessarily plane) singularity a homological theory which is the analogue of the Heegaard Floer Link theory for links of plane curve singularities.
Analysis and Simulation of Istanbul Strait Marine Traffic Management Strategies

Istanbul Strait is one of the most crowded, narrowest straits in the world. More than fifty thousand ships per year (more than one ship in ten minutes in average) pass through the Istanbul Strait. It is also assumed to be the most dangerous strait in the world due to its narrowness and nature of the sea flows in the straits. Even though the number of accidents has decreased in recent years, the risk is still high. Management of Istanbul Strait is indeed a difficult job required to control many parameters. For example, opening the strait for one or two way traffic, applying different queuing strategies, or scheduling of limited number of maritime pilots affect the strait traffic. In order to see the effect of changes in management related strategies, it may not be very practical to really apply the changes in the traffic management. Simulation of marine traffic in Istanbul Strait is very important to be able to see the effects of different management strategies and possible changes affecting the marine traffic without really applying them. This paper presents a simulation model for marine traffic in Istanbul Strait. AutoMod software is used to develop the simulation model. Different queuing strategies and management related issues are analyzed in the simulation and their effects are compared in this paper.
Investigating Imaginary Mask Estimation in Complex Masking for Speech Enhancement

Speech enhancement methods have become effective at estimating a clean magnitude spectrum from a noisy speech signal. However, they are much less effective at recovering the noise-free phase. At higher signal-to-noise ratios (SNRs) this is unimportant, but at lower SNRs the noisy phase introduces a perceptible distortion to the enhanced speech that reduces quality and intelligibility. Complex masking methods have addressed this problem to some extent but they report underestimation of the imaginary mask which in turn limits the possible phase correction. This work first analyses the problem of imaginary mask estimation and examines further its effect on both phase and magnitude masking. Second, a CNN-DNN architecture is proposed for complex mask estimation that uses a new loss function aimed at giving errors in the imaginary mask component a greater contribution in model training. Experimental results are presented that consider variations to the loss function and demonstrate that improved speech quality and intelligibility can be achieved.
From Metabolism to Vitality: Uncovering Riboflavin’s Importance in Poultry Nutrition

Simple Summary Riboflavin, an essential B-vitamin, plays a crucial role in poultry metabolism, impacting energy production, growth, and immune regulation. Its role in redox reactions and energy metabolism is vital for optimal growth and development. Riboflavin is essential for ATP production and the conversion of tryptophan into niacin. Deficiency can lead to skeletal deformities, impaired growth, and compromised immune function. Dietary riboflavin supplementation is necessary due to variable bioavailability in plant-derived sources. The vitamin is absorbed through specialized transport proteins, and its cellular uptake is facilitated by specific receptors. Riboflavin’s role in protein synthesis and its antioxidant properties influence poultry growth and defense against oxidative stress. Its impact on reproductive performance, hatchability, and overall poultry health underscores its significance in poultry nutrition. Future research should focus on its interactions with other nutrients, exploring analogs, and integrating advanced technologies like precision nutrition and nanotechnology for enhanced delivery. Abstract Riboflavin, or vitamin B2, is indispensable for poultry, profoundly impacting their metabolic equilibrium, growth, and overall health. In a climate of increasing demand for poultry products and heightened production intensity, grasping the multifaceted roles of riboflavin in domestic fowl nutrition becomes paramount. This essential vitamin serves as a precursor to two vital coenzymes, flavin mononucleotide and flavin adenine dinucleotide, integral players in pivotal redox reactions and energy metabolism. Inadequate riboflavin levels translate into stunted growth, skeletal deformities, and compromised feed conversion efficiency, thereby adversely affecting poultry performance and bottom-line profitability. Riboflavin goes beyond its fundamental role, ameliorating nutrient utilization, facilitating protein synthesis, and augmenting enzyme activity, rightfully earning its epithet as the “growth-promoting vitamin”. Poultry’s reproductive success intricately hinges on riboflavin levels, dictating egg production and hatchability. It is imperative to note that riboflavin requirements exhibit variations among poultry species and distinct production phases, emphasizing the importance of judicious and balanced supplementation strategies. Aligning dietary recommendations with genetic advancements holds the promise of fostering sustainable growth within the poultry sector. Exploring the multifaceted aspects of riboflavin empowers researchers, nutritionists, and producers to elevate poultry nutrition and overall well-being, harmonizing with the industry’s evolving demands.
Si-Kintsugi: Towards Recovering Golden-Like Performance of Defective Many-Core Spatial Architectures for AI

The growing demand for higher compute and memory capacity driven by artificial intelligence (AI) applications pushes higher core counts in modern systems. Many-core architectures exhibiting spatial interconnects with high on-chip bandwidth are ideal for these workloads due to their data movement flexibility and sheer parallelism. However, the size of such platforms makes them particularly susceptible to manufacturing defects, prompting a need for designs and mechanisms that improve yield. Despite these techniques, nonfunctional cores and links are unavoidable. Although prior works address defective cores by disabling them and only scheduling workload to functional ones, communication latency through spatial interconnects is tightly associated with the locations of defective cores and cores with assigned work. Based on this observation, we present Si-Kintsugi, a defect-aware workload scheduling framework for spatial architectures with mesh topology. First, we design a novel and generalizable workload mapping representation and cost function that integrates defect pattern information. The mapping representation is formed into a 1D vector with simple constraints, making it an ideal candidate for open source heuristic-based optimization algorithms. After a communication latency optimized workload mapping is found, dataflow between the mapped cores is automatically generated to balance communication and computation cost. Si-Kintsugi is extensively evaluated on various workloads (i.e., BERT, ResNet, GEMM) across a wide range of defect patterns and rates. Experiment results show that Si-Kintsugi generates a workload schedule that is on average 1.34× faster than the industry standard layer-pipelined schedule on defective platforms.CCS CONCEPTS• Hardware → Yield and cost optimization; • Computing methodologies → Machine learning; Planning and scheduling; • Computer systems organization → Multicore architectures.
Effect of Two Types of Control Questions and Two Question Formats on the Outcomes of Polygraph Examinations *

Abstract: Two major variations of polygraph “Control Question” testing, the Zone Comparison (ZoC) and the Modified General Question Test (MGQT) were evaluated. Within each, the type of control question, Exclusive or “time bar” (e.g., “Before you were 21, did you ever.”) and Nonexclusive or “no time bar”(e.g., “Did you ever….? ”) was manipulated in a mock theft scenario, with 80 male and 40 female subjects randomly assigned to be either innocent or guilty. Polygraphic data collected by experienced field examiners were numerically scored by an evaluator blind to all aspects of the study. Decision accuracy was not related to the type of procedure (ZoC/MGQT) used or the subject’s sex. Accuracy was significantly related to the type of control question [χ2(2) = 11.46, p = 0.003; τc = 0.29]. Nonexclusive control questions produced greater accuracy than Exclusive control questions on both innocent and guilty subjects. These results and subjects’ self‐reports support the general “theory” on which control question (CQ) testing is based. The need for better empirical support of accepted dogma and current field practices is strongly indicated by these findings.
Nitric oxide synthase 1 as a potential modifier gene of decline in lung function in patients with cystic fibrosis

Background: The severity of lung disease varies widely in patients with cystic fibrosis (CF) who have the same type of mutations of the cystic fibrosis transmembrane regulator (CFTR) gene, suggesting involvement of “modifier” genes. The nitric oxide synthase 1 (NOS1) gene is a candidate for this role because exhaled nitric oxide (NO) is reduced in patients with CF and NOS1 activity contributes to transepithelial ionic transport, immune defence, and non-specific inflammation of the airways. Methods: Dinucleotide GT repeat polymorphism was studied in the 5′ untranslated region of the NOS1 gene, immediately upstream from the transcription initiation site, in 59 patients with CF and 59 healthy controls. Results: Nineteen alleles of the NOS1 gene were identified according to the number of GT repeats (from 18 to 36) in the 5 untranslated region. Exhaled NO levels were significantly correlated with the number of GT repeats. Patients with CF who had the NOS1 genotype associated with high NO production had a slower decline in lung function during the 5 year follow up period. There was no confounding effect of age, chronic bacterial colonisation of the airway, or CFTR genotype. Conclusions: These data suggest a possible link between the NOS1 gene locus and the rate of decline in lung function in patients with CF.
Fifty-five per cent return to competitive sport following anterior cruciate ligament reconstruction surgery: an updated systematic review and meta-analysis including aspects of physical functioning and contextual factors

Background The aim of this study was to update our original systematic review of return to sport rates following anterior cruciate ligament (ACL) reconstruction surgery. Method Electronic databases were searched from April 2010 to November 2013 for articles reporting the number of patients returning to sport following ACL reconstruction surgery. Return to sport rates, physical functioning and contextual data were extracted and combined using random-effects meta-analyses. Data from the original review (articles published up to April 2010) were combined with data from the updated search. Results Sixty-nine articles, reporting on 7556 participants, were reviewed. On average, 81% of people returned to any sport, 65% returned to their preinjury level of sport and 55% returned to competitive level sport after surgery. Symmetrical hopping performance (d=0.3) and the contextual factors of younger age (d=−0.3), male gender (OR=1.4), playing elite sport (OR=2.5) and having a positive psychological response (d=0.3) favoured returning to the preinjury level sport. Receiving a hamstring tendon autograft favoured returning to competitive level sport (OR=2.4), whereas receiving a patellar tendon autograft favoured returning to the preinjury level sport (OR=1.2). Conclusions Returning to sport varied according to different physical functioning and contextual factors, which could warrant additional emphasis in postoperative rehabilitation programmes to maximise participation.

Neural and behavioural correlates of empathy and morality and their associations with psychopathic traits

Psychopathy is a personality disorder that can be defined by profound disturbances in empathic response to others and repeated engagement in immoral behaviour. This thesis set out to investigate how individual differences in psychopathic traits in the general population are associated with variability in distinct components of empathy and morality. This thesis endeavoured to answer five outstanding research questions: 1) Given the complexity and multidimensionality of empathy and morality constructs, which components of these constructs are associated with psychopathic traits at the behavioural level? [Chapters 2-3] 2) Are behavioural correlates of empathy and morality in psychopathic traits specific to affective-interpersonal traits/lifestyle-antisocial traits, or common to both? [Cs. 2-3] 3) Are these correlates consistent across genders? [Cs. 2-3] 4) Are associations between psychopathic traits and empathic [C. 4] and 5) moral processing reflected at the neural level [C. 5]? This thesis’ findings suggest that: 1) individual differences in psychopathic traits are associated with lesser empathic response to emotional stimuli, lesser propensity to feel moral emotions and atypical moral decision-making; 2) empathic atypicalities are driven by the joint variance between affective-interpersonal and lifestyle-antisocial facets, but those related to affective aspects of moral cognition seem to be driven by variance in affective-interpersonal traits; 3) empathic and moral atypicalities seem to be similar in men and women; 4) atypical amygdala and anterior insula function may represent neural markers of disrupted empathic processing for individuals with high levels of psychopathic traits; and 5) atypical functioning of the vmPFC/mOFC during moral processing may contribute to the disordered lifestyle and antisocial behaviour exhibited by individuals with high levels of psychopathic traits. These findings contribute to a more comprehensive understanding of the empathic and moral processing impairments that underlie psychopathic traits.

Sleep-related breathing disorders in adolescents aged 12 to 16 years : clinical and polygraphic findings.

STUDY OBJECTIVES To determine the frequency, symptoms, and polygraphic features of sleep-related breathing disorders (SRBD) in adolescents aged 12 to 16 years. DESIGN Cross-sectional study. SETTING Randomly selected secondary schools in the city of Seville, SPAIN: PARTICIPANTS A general population sample of adolescents (n = 101; mean [+/- SD] age, 13.2 +/- 0.8 years). INTERVENTIONS An 82-item questionnaire regarding anthropometric data and nocturnal and daytime symptoms suggestive of SRBD was administered. Symptoms were evaluated according to a 4-point frequency scale. Snorers answered "sometimes" or "often" in the question about snoring, and nonsnorers answered "never" or "rarely. " All subjects underwent an overnight cardiorespiratory polygraphy at home. RESULTS Twenty-nine percent of the subjects were snorers. Excessive daytime sleepiness was present in 14% of subjects, and sleep apnea was present in 3%. Polygraphy showed a respiratory disturbance index > or = 10 in 18 subjects (17.8%), but concurrent symptoms highly suggestive of SRBD were found in only 2 subjects (1.9%). Snorers had higher waist-to-hip ratios and a higher frequency of witnessed apnea or labored breathing as well as higher values of respiratory events as compared with nonsnorers. However, oximetry data were similar in both groups. CONCLUSIONS In a nonselected group of adolescents aged 12 to 16 years, the frequency of symptoms potentially associated with SRBD was similar to that reported for younger children. Snoring was associated with a higher occurrence of other nocturnal symptoms, a more central pattern of body fat distribution, and a higher respiratory disturbance index as compared with nonsnorers. Although polygraphic abnormalities were mild, two cases of probable SRBD were found with a prevalence rate of 1.9%.
Role of poly(ADP-ribose) synthetase activation in the suppression of cellular energetics in response to nitric oxide and peroxynitrite.

Poly(ADP-ribose) synthetase (PARS) activation: a pathway of cellular oxidant injury PARS is a protein-modifying and nucleotidepolymerizing enzyme that is abundantly present in the nucleus [l]. Its activation results in the cleavage of NAD' into ADP-ribose and nicotinamide. In turn, PARS covalently attaches ADPribose to various proteins, including nuclear proteins, histones and an automodification domain of PARS itself. PARS then extends the initial ADP-ribose group into a nucleic acid-like polymer, poly(ADP-ribose) [ 11. The physiological function of PARS has been the subject of debate. Initial work has implicated it in the process of DNA repair [ l ] . However, according to more recent data, it is not efficient as a DNA-repair enzyme [2]. On the contrary, it has been suggested that the physiological role of PARS is to slow cellular metabolism as an adaptive response to altered environmental conditions [3-51. In addition, there is also some evidence that PARS plays a role in the regulation of gene expression and cell differentiation, by regulating histone reshuffling
