Combining Distance to Class Centroids and Outlier Discounting for Improved Learning with Noisy Labels

In this paper, we propose a new approach for addressing the challenge of training machine learning models in the presence of noisy labels. By combining a clever usage of distance to class centroids in the items' latent space with a discounting strategy to reduce the importance of samples far away from all the class centroids (i.e., outliers), our method effectively addresses the issue of noisy labels. Our approach is based on the idea that samples farther away from their respective class centroid in the early stages of training are more likely to be noisy. We demonstrate the effectiveness of our method through extensive experiments on several popular benchmark datasets. Our results show that our approach outperforms the state-of-the-art in this area, achieving significant improvements in classification accuracy when the dataset contains noisy labels.
Vision and Structured-Language Pretraining for Cross-Modal Food Retrieval

Vision-Language Pretraining (VLP) and Foundation models have been the go-to recipe for achieving SoTA performance on general benchmarks. However, leveraging these powerful techniques for more complex vision-language tasks, such as cooking applications, with more structured input data, is still little investigated. In this work, we propose to leverage these techniques for structured-text based computational cuisine tasks. Our strategy, dubbed VLPCook, first transforms existing image-text pairs to image and structured-text pairs. This allows to pretrain our VLPCook model using VLP objectives adapted to the strutured data of the resulting datasets, then finetuning it on downstream computational cooking tasks. During finetuning, we also enrich the visual encoder, leveraging pretrained foundation models (e.g. CLIP) to provide local and global textual context. VLPCook outperforms current SoTA by a significant margin (+3.3 Recall@1 absolute improvement) on the task of Cross-Modal Food Retrieval on the large Recipe1M dataset. We conduct further experiments on VLP to validate their importance, especially on the Recipe1M+ dataset. Finally, we validate the generalization of the approach to other tasks (i.e, Food Recognition) and domains with structured text such as the Medical domain on the ROCO dataset.

Efficacy of Aflibercept as initial treatment for neovascular age-related macular degeneration in an Iraqi patient sample

Age-related macular degeneration (AMD) is a progressive degenerative eye disorder that primarily affects individuals over 50. It causes gradual loss of central vision and can lead to irreversible severe visual loss if left untreated. AMD is a leading cause of blindness in the developed world. This study aimed to investigate the effects of a loading dosage of intravitreal Aflibercept on functional and morphological responses in neovascular AMD, considering demographic characteristics and the link between AMD-related retinal symptoms at presentations. A prospective interventional study was conducted from November 2021 to September 2022 on a sample of Iraqi patients with neovascular AMD who had active choroidal neovascularization (CNV) lesions confirmed by OCT-A and received intravitreal Aflibercept 2mg injection as initial therapy (3 loading doses). Best-corrected visual acuity (BCVA) was used to measure functional responses, and central macular thickness (CMT) and maximum area of the retinal thickness (MART) (by SD-OCT) were used to measure morphological responses. The study included 48 patients (57 eyes) with active neovascular AMD. The mean difference of BCVA in log MAR (0.2 ± 0.7) significantly improved from 1.3±0.7 at baseline to 1.1±0.8 after loading Aflibercept (P=0.034). The mean difference in CMT 113.6 ± 125.9 was statistically significant (P<0.0001). Also, the mean change in MART significantly decreased from 444.2 ± 127.1 µm at baseline to 348.7±74.5 µm (p < 0.0001) after loading Aflibercept. This study demonstrated that Aflibercept is a functionally and anatomically successful treatment for neovascular AMD.
Semaglutide in renal ischemia-reperfusion injury in mice

Ischemia and reperfusion injury (I/R) is a serious condition leading to organ failure, characterized by poor blood supply followed by rapid resuscitation of blood flow and reoxygenation. Renal failure caused by renal ischemia has high mortality and morbidity. This study aimed to explore the potential role of Semaglutide as a novel and effective therapeutic strategy for acute renal failure. Additionally, we aimed to assess the possible protective effect of Semaglutide on kidney I/R injury in mice through modulation of the inflammatory and oxidative pathways via phosphatidylinositol 3-kinase/adenosine triphosphate (PI3K/AKT) activation. We employed twenty-eight albino mice to induce the I/R injury model by clamping the renal artery for 30 min followed by a period of reperfusion for 2 hours. The control group was exposed to I/R injury, while the Semaglutide-treated group was pretreated with the drug 12 hours before induction of ischemia at a dose of 100 nmol/L/kg via the intraperitoneal route (i.p). In addition, the DMSO-treated group was subjected to similar conditions to the Semaglutide-treated group. At the end of the experiments, kidneys and blood samples were collected for investigation. Semaglutide could act as a protective agent against acute kidney injury by reducing inflammatory molecules such as tumor necrosis factor-alpha (TNF-α) and its cognate receptor, TNF-α R, interleukine-6 (IL-6). Furthermore, Semaglutide reduced F8 isoprostane levels, increased PI3K and AKT levels in renal tissues, and mitigated renal damage. Semaglutide had renoprotective effects via modulation of the inflammatory response and oxidative pathway by targeting the PI3K/AKT signaling pathway.
Definition of generalized Bratteli diagrams 6 2 . 2 . Isomorphism of generalized Bratteli diagrams 8 3

Bratteli-Vershik models have been very successfully applied to the study of various dynamical systems, in particular, in Cantor dynamics. In this paper, we study dynamics on the path spaces of generalized Bratteli diagrams that form models for noncompact Borel dynamical systems. Generalized Bratteli diagrams have countably infinite many vertices at each level, thus the corresponding incidence matrices are also countably infinite. We emphasize differences (and similarities) between generalized and classical Bratteli diagrams. Our main results: (i)We utilize Perron-Frobenius theory for countably infinite matrices to establish criteria for the existence and uniqueness of tail-invariant path-space measures (both probability and σ-finite). (ii) We provide criteria for the topological transitivity of the tail equivalence relation. (iii) We describe classes of stationary generalized Bratteli diagrams (hence Borel dynamical systems) that: (a) do not support a probability tailinvariant measure, (b) do not admit a continuous Vershik map, (c) are not uniquely ergodic with respect to the tail equivalence relation. (iv) We provide an application of the theory of stochastic matrices to analyze diagrams with positive recurrent incidence matrices.
ANALYSIS AND APPROXIMATION OF A SCALAR CONSERVATION LAW WITH A FLUX FUNCTION WITH DISCONTINUOUS COEFFICIENTS

We study here a model of conservative nonlinear conservation law with a flux function with discontinuous coefficients, namely the equation ut + (k(x)u(1 - u))x = 0. It is a particular entropy condition on the line of discontinuity of the coefficient k which ensures the uniqueness of the entropy solution. This condition is discussed and justified. On the other hand, we perform a numerical analysis of the problem. Two finite volume schemes, the Godunov scheme and the VFRoe-ncv scheme, are proposed to simulate the conservation law. They are compared with two finite volume methods classically used in an industrial context. Several tests confirm the good behavior of both new schemes, especially through the discontinuity of permeability k (whereas a loss of accuracy may be detected when industrial methods are performed). Moreover, a modified MUSCL method which accounts for stationary states is introduced.

Strain-activated edge reconstruction of graphene nanoribbons

The edge structure and width of graphene nanoribbons (GNRs) are crucial factors for the electronic properties. A combination of experiment and first-principles calculations allows us to determine the mechanism of the hexagonhexagon to pentagon-heptagon transformation. GNRs thinner than 2 nm have been fabricated by bombardment of graphene with high-energetic Au clusters. The edges of the GNRs are modified in situ by electron irradiation. Tensile strain along the edge decreases the transformation energy barrier. Antiferromagnetism and a direct band gap are found for a zigzag GNR, while a fully reconstructed GNR shows an indirect band gap. A GNR reconstructed on only one edge exhibits ferromagnetism. We propose that strain is an effective method to tune the edge and, therefore, the electronic structure of thin GNRs for graphene-based electronics.
On Infinite Tensor Products of Von Neumann Algebras

Q-? ) 0ij. This problem has been completely solved in a series of papers [1, 3, 9, 10, 15] when each j if of type I, and partial results have been obtained in the general case [4, 13]. In order that 2 be of type I it is necessary that each Nj is of type I [11], hence that case is completely taken care of in the quoted papers. Similarly, if 2 is finite each 2? j is finite, hence a result of Bures [4, Thm. 4.3] gives necessary and sufficient conditions in order that 2 be finite. If one of the gj is of type III then 2 is of type III [11]. Therefore, what is left is to give necessary and sufficient conditions in order that 2 be semi-finite under the assumption that each ? j is semi-finite. This will be done in the present paper: the result is then quite analogous to that when each 2? j is a type I factor. Our proof differs from that in the type I situation in that we avoid most of the measure theoretic arguments of Moore [9] and some of the manipulations with infinite series by him and Takenouchi [15]. Instead we use some powerful results of Tomita [17] and Takesaki [16] on the modular automorphisms of von Neumann algebras induced by faithful normal states. For our purposes the simplest defintion of modular automorphisms is given by Takesaki [16, Thms. 13. 1 and 13. 2]. Let 2 be a von Neumann algebra and p a faithful normal state of S. p is said to satisfy the KMS boundary condition with respect to a strongly continuous one parameter *-automorphism group at, -oo 0 such that for each pair of operators A, B in 2 there is a function F(z) holomorphic in the strip 0 < Im z < 8 with boundary values, F(t)-1p (gt (A)B) and F(t + iP) p (Bgt (A) ). Let now p be a faithful
Stability of equatorially symmetric and asymmetric climates under annual solar forcing

A simple coupled ocean‐atmosphere model is developed to investigate the maintenance of the latitudinal asymmetries of the sea surface temperature (SST) field and the intertropical convergence zone (ITCZ). the model is of the minimum degree of freedom necessary to describe latitudinal asymmetries, computing only the difference between the hemispherical SST maxima. A wind‐evaporation‐SST feedback is found to destabilize the equatorial symmetry established by the annual‐mean solar radiation. By considering the nonlinear SST threshold for deep convection, equatorially asymmetric steady states are reached, with a single ITCZ off the equator.
ASM: An Adaptive Secure Multicore for Co-located Mutually Distrusting Processes

With the ever-increasing virtualization of software and hardware, the privacy of user-sensitive data is a fundamental concern in computation outsourcing. Secure processors enable a trusted execution environment to guarantee security properties based on the principles of isolation, sealing, and integrity. However, the shared hardware resources within the microarchitecture are increasingly being used by co-located adversarial software to create timing-based side-channel attacks. State-of-the-art secure processors implement the strong isolation primitive to enable non-interference for shared hardware but suffer from frequent state purging and resource utilization overheads, leading to degraded performance. This article proposes ASM, an adaptive secure multicore architecture that enables a reconfigurable, yet strongly isolated execution environment. For outsourced security-critical processes, the proposed security kernel and hardware extensions allow either a given process to execute using all available cores or co-execute multiple processes on strongly isolated clusters of cores. This spatio-temporal execution environment is configured based on resource demands of processes, such that the secure processor mitigates state purging overheads and maximizes hardware resource utilization.
Population genomics of helminth parasites

Abstract Next generation sequencing technologies have facilitated a shift from a few targeted loci in population genetic studies to whole genome approaches. Here, we review the types of questions and inferences regarding the population biology and evolution of parasitic helminths being addressed within the field of population genomics. Topics include parabiome, hybridization, population structure, loci under selection and linkage mapping. We highlight various advances, and note the current trends in the field, particularly a focus on human-related parasites despite the inherent biodiversity of helminth species. We conclude by advocating for a broader application of population genomics to reflect the taxonomic and life history breadth displayed by helminth parasites. As such, our basic knowledge about helminth population biology and evolution would be enhanced while the diversity of helminths in itself would facilitate population genomic comparative studies to address broader ecological and evolutionary concepts.
Experimental study on the oscillatory Kelvin–Helmholtz instability of a planar liquid sheet in the presence of axial oscillating gas flow

Abstract The oscillatory Kelvin–Helmholtz (K–H) instability of a planar liquid sheet was experimentally investigated in the presence of an axial oscillating gas flow. An experimental system was initiated to study the oscillatory K–H instability. The surface wave growth rates were measured and compared with theoretical results obtained using the authors’ early linear method. Furthermore, in a larger parameter range experimentally studied, it is interesting that there are four different unstable modes: first disordered mode (FDM), second disordered mode (SDM), K–H harmonic unstable mode (KHH) and K–H subharmonic unstable mode (KHS). These unstable modes are determined by the oscillating amplitude, oscillating frequency and liquid inertia force. The frequencies of KHH are equal to the oscillating frequency; the frequency of KHS equals half the oscillating frequency, while the frequencies of FDM and SDM are irregular. By considering the mechanism of instability, the instability regime maps on the relative Weber number versus liquid Weber number (Werel–Wel) and the Weber number ratio versus the oscillating frequency (Werel/Wel–$\varOmega$s2) were plotted. Among these four modes, KHS is the most unexpected: the frequency of this mode is not equal to the oscillating frequency, but the surface wave can also couple with the oscillating gas flow. Linear instability theory was applied to divide the parameter range between the different unstable modes. According to linear instability theory, K–H and parametric unstable regions both exist. However, note that all four modes (KHH, KHS, FDM and SDM) corresponded primarily to the K–H unstable region obtained from the theoretical analysis. Nevertheless, the parametric unstable mode was also observed when the oscillating frequency and amplitude were relatively low, and the liquid inertia force was relatively high. The surface wave amplitude was small but regular, and the evolution of this wave was similar to that of Faraday waves. The wave oscillating frequency was half that of the surface wave.
Upscaled dynamic capillary pressure for two-phase flow in porous media

Abstract A closed expression for the average pressure difference (often called the macroscopic dynamic capillary pressure in the literature) is proposed for two-phase, Newtonian, incompressible, isothermal and creeping flow in homogeneous porous media. This upscaled equation complements the average equations for mass and momentum transport derived in a previous article. Consistently with this work, the expression is derived employing a simplified version of the volume-averaging method that makes use of elements of the adjoint method and Green's formula. The resulting equation for the average pressure difference is novel, as it shows that this quantity is controlled by the pressure gradient (and body forces) in each phase, as well as interfacial effects, and is applicable to situations in which the fluid–fluid interface is not necessarily at its steady position. The effective-medium quantities associated with the sources are all obtained from the solution of a single adjoint (or closure) problem to be solved on a (periodic) unit cell representative of the process. The average pressure difference predicted by the derived expression is validated through excellent comparisons with direct numerical simulations performed in a model porous structure.

Biofeedback Has Therapeutic Effects on Asthma, Although Additional Research Is Needed to Document Specificity

Asthma is a common disorder leading to significant disability and healthcare cost throughout the world. Although medical treatment is usually highly effective in controlling it, asthma medicines often have high costs and attendant side effects. Biofeedback is an inexpensive noninvasive alternative with minimal side effects. This paper reviews evidence for two validated biofeedback treatments for treating asthma, heart rate variability biofeedback (HRVB), and muscle relaxation with surface electromyographic biofeedback. In multiple studies, although most of them are of modest size, both methods have clinically meaningful results, often allowing decreases in the use of steroid medication. Further research is needed to prove which specific components of HRVB are responsible for clinical effects, and to determine asthma populations that can best benefit from these methods. Despite demonstrated effectiveness, few insurance schemes reimburse for biofeedback, and national guidelines consider it only as worthy of further investigation. Funding for the requisite large-scale clinical trials remains lacking, creating a limbo-like status quo for these useful methods.
Tympanostomy Tubes: Are They Necessary? A Systematic Review on Implementation in Cleft Care

Objective To understand the indication for and the effects of early ventilation tube insertion (VTI) on hearing and speech for patients with cleft lip and/or palate (CLP). Design We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-guided systematic review of relevant literature. Setting Setting varied by geographical location and level of clinical care across studies. Patients, Participants Patients with CLP who underwent VTI were included. Interventions No interventions were performed. Main Outcome Measure(s) Primary outcome measures were hearing and speech following VTI. Secondary outcome measures were tube-related and middle ear complications. Early VTI occurred before or at time of palatoplasty while late VTI occurred after palatoplasty. Results Twenty-three articles met inclusion criteria. Articles varied among study design, outcome measures, sample size, follow-up, and quality. Few studies demonstrated support for early VTI. Many studies reported no difference in hearing or speech between early and late VTI. Others reported worse outcomes, greater likelihood of complications, or needing repeat VTI following early tympanostomy placement. Several studies had significant limitations, including confounding variables, small sample size, or not reporting on our primary outcome. Conclusions No consistency was found regarding which patients would benefit most from early VTI. Given the aforementioned variability and sub-optimal methodologies, additional studies are warranted to provide stronger evidence regarding VTI timing in cleft care.
