Long-Time Dynamics in Quantum Spin Lattices: Ergodicity and Hydrodynamic Projections at All Frequencies and Wavelengths
Authors: Ampelogiannis Dimitrios , Doyon Benjamin 
Published: May 2023

AbstractObtaining rigorous and general results about the non-equilibrium dynamics of extended many-body systems is a difficult task. In quantum lattice models with short-range interactions, the Lieb–Robinson bound tells us that the spatial extent of operators grows at most linearly in time. But what happens within this light-cone? We discuss rigorous results on ergodicity and the emergence of the Euler hydrodynamic scale in correlation functions, which establish fundamental principles at the root of non-equilibrium physics. One key idea of the present work is that general structures of Euler hydrodynamics, obtained under ballistic scaling, follow independently from the details of the microscopic dynamics, and in particular do not necessitate chaos; they are consequences of “extensivity”. Another crucial observation is that these apply at arbitrary frequencies and wavelengths. That is, long-time, persistent oscillations of correlation functions over ballistic regions of spacetime, which may be of microscopic frequencies and wavelengths, are predicted by a general Euler-hydrodynamic theory that takes the same form as that for smoothed-out correlation functions. This involves a natural extension of notions of conserved quantities and hydrodynamic projection and shows that the Euler hydrodynamic paradigm covers the full frequency-wavelength plane.
NLS ground states on the half-line with point interactions
Authors: Boni Filippo , Carlone Raffaele 
Published: May 2023

AbstractWe investigate the existence and the uniqueness of NLS ground states of fixed mass on the half-line in the presence of a point interaction at the origin. The nonlinearity is of power type, and the regime is either $$L^{2}$$

L
2

-subcritical or $$L^{2}$$

L
2

-critical, while the point interaction is either attractive or repulsive. In the $$L^{2}$$

L
2

-subcritical case, we prove that ground states exist for every mass value if the interaction is attractive, while ground states exist only for sufficiently large masses if the interaction is repulsive. In the latter case, if the power is less or equal to four, ground states coincide with the only bound state. If instead, the power is greater than four, then there are values of the mass for which two bound states exist, and neither of the two is a ground state, and values of the mass for which two bound states exist, and one of them is a ground state. In the $$L^{2}$$

L
2

-critical case, we prove that ground states exist for masses strictly below a critical mass value in the attractive case, while ground states never exist in the repulsive case.

Abstract
Background
No randomised clinical trials (RCTs) have simultaneously compared the safety of open (OA), transperitoneal laparoscopic (TLA), posterior retroperitoneal (PRA), and robotic adrenalectomy (RA) for resecting adrenal tumours.

Aim
To evaluate outcomes for OA, TLA, PRA, and RA from RCTs.

Methods
A NMA was performed according to PRISMA-NMA guidelines. Analysis was performed using R packages and Shiny.

Results
Eight RCTs with 488 patients were included (mean age: 48.9 years). Overall, 44.5% of patients underwent TLA (217/488), 37.3% underwent PRA (182/488), 16.4% underwent RA (80/488), and just 1.8% patients underwent OA (9/488). The mean tumour size was 35 mm in largest diameter with mean sizes of 44.3 mm for RA, 40.9 mm for OA, 35.5 mm for TLA, and 34.4 mm for PRA (P < 0.001). TLA had the lowest blood loss (mean: 50.6 ml), complication rates (12.4%, 14/113), and conversion to open rates (1.3%, 2/157), while PRA had the shortest intra-operative duration (mean: 94 min), length of hospital stay (mean: 3.7 days), lowest visual analogue scale pain scores post-operatively (mean: 3.7), and was most cost-effective (mean: 1728 euros per case). At NMA, there was a significant increase in blood loss for OA (mean difference (MD): 117.00 ml (95% confidence interval (CI): 1.41–230.00)) with similar blood loss observed for PRA (MD: − 10.50 (95% CI: − 83.40–65.90)) compared to TLA.

Conclusion
LTA and PRA are important contemporary options in achieving favourable outcomes following adrenalectomy. The next generation of RCTs may be more insightful for comparison surgical outcomes following RA, as this approach is likely to play a future role in minimally invasive adrenalectomy.

Published: May 2023

AbstractUsing time-driven activity-based costing (TDABC), we examined resource allocation and costs for HIV services throughout Tanzania at patient and facility levels. This national, cross-sectional analysis of 22 health facilities quantified costs and resources associated with 886 patients receiving care for five HIV services: antiretroviral therapy, prevention of mother-to-child transmission, HIV testing and counseling, voluntary medical male circumcision, and pre-exposure prophylaxis. We also documented total provider-patient interaction time, the cost of services with and without inclusion of consumables, and conducted fixed-effects multivariable regression analyses to examine patient- and facility-level correlates of costs and provider-patient time. Findings showed that resources and costs for HIV care varied significantly throughout Tanzania, including as a function of patient- and facility-level characteristics. While some variation may be preferable (e.g., needier patients received more resources), other areas suggested a lack of equity (e.g., wealthier patients received more provider time) and presented opportunities to optimize care delivery protocols.
Analysis of the Cryptographic Algorithms in IoT Communications

Published: May 2023

AbstractThe advances on recent communication paradigms brings new security and privacy challenges, mainly about personal data collection by smart devices. Resource constrained devices face serious issues to run complex cryptographic algorithms. Trying to evaluate the performance impact of those algorithms in usual and common devices used in smart homes, in this paper we tested the impact of different cryptographic algorithms in low computational devices, typically used in smart devices applied in smart homes, testing different security configurations and using the two most used transport protocols (HTTP and MQTT). The experiment measures their effects on six commonly used embedded devices in IoT WSNs: ESP8622, ESP32, and Raspberry Pi (RPi) from 1 to 4. The experiment measured the power consumption, message delay, and additional message length (bytes). Moreover, the analysis was also used to model security algorithms. The experimental results from long runs (72 hours) reveal the cryptographic solution choice is significant for the message delay and additional message length.

Published: May 2023

Abstract
Background
Commensal bacteria secrete metabolites that reach distant cancer cells through the circulation and influence cancer behavior. Deoxycholic acid (DCA), a hormone-like metabolite, is a secondary bile acid specifically synthesized by intestinal microbes. DCA may have both pro- and antineoplastic effects in cancers.

Methods and results
The pancreatic adenocarcinoma cell lines, Capan-2 and BxPC-3, were treated with 0.7 µM DCA, which corresponds to the reference concentration of DCA in human serum. DCA influenced the expression of epithelial to mesenchymal transition (EMT)-related genes, significantly decreased the expression level of the mesenchymal markers, transcription factor 7- like 2 (TCF7L2), snail family transcriptional repressor 2 (SLUG), CLAUDIN-1, and increased the expression of the epithelial genes, zona occludens 1 (ZO-1) and E-CADHERIN, as shown by real-time PCR and Western blotting. Consequently, DCA reduced the invasion capacity of pancreatic adenocarcinoma cells in Boyden chamber experiments. DCA induced the protein expression of oxidative/nitrosative stress markers. Moreover, DCA reduced aldehyde dehydrogenase 1 (ALDH1) activity in an Aldefluor assay and ALDH1 protein level, suggesting that DCA reduced stemness in pancreatic adenocarcinoma. In Seahorse experiments, DCA induced all fractions of mitochondrial respiration and glycolytic flux. The ratio of mitochondrial oxidation and glycolysis did not change after DCA treatment, suggesting that cells became hypermetabolic.

Conclusion
DCA induced antineoplastic effects in pancreatic adenocarcinoma cells by inhibiting EMT, reducing cancer stemness, and inducing oxidative/nitrosative stress and procarcinogenic effects such as hypermetabolic bioenergetics.

AbstractCommunity-clinical linkage models (CCLM) have the potential to reduce health disparities, especially in underserved communities; however, the COVID-19 pandemic drastically impacted their implementation. This paper explores the impact of the pandemic on the implementation of CCLM intervention led by community health workers (CHWs) to address diabetes disparities among South Asian patients in New York City. Guided by the Consolidated Framework for Implementation Research (CFIR), 22 stakeholders were interviewed: 7 primary care providers, 7 CHWs, 5 community-based organization (CBO) representatives, and 3 research staff. Semi-structured interviews were conducted; interviews were audio-recorded and transcribed. CFIR constructs guided the identification of barriers and adaptations made across several dimensions of the study’s implementation context. We also explored stakeholder-identified adaptations used to mitigate the challenges in the intervention delivery using the Model for Adaptation Design and Impact (MADI) framework. (1) Communication and engagement refers to how stakeholders communicated with participants during the intervention period, including difficulties experienced staying connected with intervention activities during the lockdown. The study team and CHWs developed simple, plain-language guides designed to enhance digital literacy. (2) Intervention/research process describes intervention characteristics and challenges stakeholders faced in implementing components of the intervention during the lockdown. CHWs modified the health curriculum materials delivered remotely to support engagement in the intervention and health promotion. (3) community and implementation context pertains to the social and economic consequences of the lockdown and their effect on intervention implementation. CHWs and CBOs enhanced efforts to provide emotional/mental health support and connected community members to resources to address social needs. Study findings articulate a repository of recommendations for the adaptation of community-delivered programs in under-served communities during a time of public health crises.

AbstractAlthough digital health solutions are increasingly popular in clinical psychiatry, one application that has not been fully explored is the utilization of survey technology to monitor patients outside of the clinic. Supplementing routine care with digital information collected in the “clinical whitespace” between visits could improve care for patients with severe mental illness. This study evaluated the feasibility and validity of using online self-report questionnaires to supplement in-person clinical evaluations in persons with and without psychiatric diagnoses. We performed a rigorous in-person clinical diagnostic and assessment battery in 54 participants with schizophrenia (N = 23), depressive disorder (N = 14), and healthy controls (N = 17) using standard assessments for depressive and psychotic symptomatology. Participants were then asked to complete brief online assessments of depressive (Quick Inventory of Depressive Symptomatology) and psychotic (Community Assessment of Psychic Experiences) symptoms outside of the clinic for comparison with the ground-truth in-person assessments. We found that online self-report ratings of severity were significantly correlated with the clinical assessments for depression (two assessments used: R = 0.63, p < 0.001; R = 0.73, p < 0.001) and psychosis (R = 0.62, p < 0.001). Our results demonstrate the feasibility and validity of collecting psychiatric symptom ratings through online surveys. Surveillance of this kind may be especially useful in detecting acute mental health crises between patient visits and can generally contribute to more comprehensive psychiatric treatment.
The experience of dysmenorrhea
Authors: Serrahima Carlota , Martínez Manolo 
Published: May 2023

AbstractDysmenorrhea, or menstrual pain, is regularly suffered by 45 to 95% of menstruating women. Despite its prevalence, and despite the philosophical importance of pain as a general phenomenon, dysmenorrhea has been all but completely overlooked in contemporary analytic philosophy of mind. This paper aims at rectifying this situation. We single out three properties of what is often considered the paradigmatic case of painful experience, what we call injury-centered pains, and argue that dysmenorrhea does not have any of them, and hence that it does not neatly conform to the injury-centered model of pain. This calls into question the centrality of the injury-centered model, and suggests novel research avenues within theoretical debates on affectivity.

Published: May 2023

AbstractFlow prediction is regarded as a major computational process in strategic water resources planning. Prediction’s lead time has an inverse relationship with results’ accuracy and certainty. This research studies the impact of climate-atmospheric indices on surface runoff predictions with a long lead time. To this end, the correlation of 36 long-distance climate indices with runoff was examined at 10 key nodes of the Great Karun multi-reservoir system in Iran, and indices with higher correlation are divided into 4 different groups. Then, using Artificial Neural Network (ANN) and Ensemble Learning to combine the input variables, flow is predicted in 6-month horizons, and results are compared with observed values. To assess the impact of extending the prediction lead time, results from the proposed model are compared with those of a monthly prediction model. The performed comparison shows that using an ensemble approach improves the final results significantly. Moreover, Tropical Pacific SST EOF, Caribbean SST, and Nino1 + 2 indices are found to be influential parameters to the basin’s inflow. It is observed that the performance of the prediction process varies in different hydrological conditions and the best results are obtained for dry seasons.
Calculation method of equivalent permeability of dual-porosity media considering fractal characteristics and fracture stress sensitivity
Authors: Luo Xiang , Cheng Youyou , Tan Chengqian 
Published: May 2023

AbstractIn the petroleum industry, the accurate calculation of equivalent permeability of dual medium is very important for the estimation of reserves and the design of oil and gas production. At present, there are many methods to calculate the equivalent permeability of dual medium. These methods have their own advantages and disadvantages, and are suitable for different medium characteristics and physical problems, but they cannot calculate the equivalent permeability of dual medium under reservoir conditions. Thus, the emergence of fractal theory provides a theoretical basis for us to study the law of fluid transport in randomly distributed pores and fractures. Many scholars have deduced the analytical solution of the fractal model of double-porosity media, and the fractal dimension of the rock matrix and fracture network has been widely used in the permeability model of dual-porosity media. It has been proven that fracture permeability and pore matrix permeability considering fractal properties can be realistically applied. In this work, the fractal dimension of the rock matrix and fracture network aperture surface tortuosity are introduced to establish a dual-permeability calculation model considering the fracture closure effect. Taking the Yanchi Chang 8 area of the Ordos Basin as an example, comparing the results of the numerical simulation model and fractal model, the proposed two-porosity medium model considering the stress closure effect is more accurate. The sensitivity analysis of each parameter in the equivalent permeability model shows that considering the effect of stress closure reduced the fracture and pore aperture. The equivalent permeability is significantly influenced by the fracture inclination, the fractal dimension of the fracture aperture, and the fractal dimension of the matrix pore diameter. The rougher fracture surface and more tortuous capillary path forces particles to move longer distances, thereby reducing the permeability of the fracture network.
A new weighted extreme learning machine based on elastic net regularization embedded exponential regularized discriminative dictionary learning for image classification
Authors: Wu Di , Zhao PinYi , Wan Qin 
Published: May 2023

AbstractIt is well known that discriminative sparse representation can significantly improve the performance of image classification. However, there remain several tricky issues to be addressed due to the unsatisfied performance and high time consumption. In this paper, a novel classification framework called weighted extreme learning machine exponential regularized discriminative dictionary learning (WELM-ERDDL) is proposed to address these issues. The main contributions of this paper include (1) the WELM is embedded with ERDDL via exponential regularized linear discriminative analysis (ERLDA) for feature mappings while enabling nonlinear and diverse feature representation; (2) in the ELM learning process, the elastic net regularization is utilized to optimize more robust and meaningful output weights; (3) an effective weight update rule is designed for WELM. To verify the effectiveness of the proposed method, several experiments are conducted on real-world image classification databases. The results show that the proposed WELM-ERDDL framework is even more efficient than other state-of-the-art algorithms in general.

Published: May 2023

AbstractPurposeCarbon dioxide (CO2) lasers enable precise vaporization of lesions with minimal bleeding and have been widely used to excise a wide variety of lesions with good results. Papillomatosis is a disorder characterized by a wart-like growth that tends to recur relentlessly after surgical removal or medical treatment. Treatment of pediatric facial papillomatosis by utilizing a CO2 laser is a viable alternative strategy. This paper presents a case of an 8-month-old child with facial papilloma, that we treated by ablation using a CO2 laser, and discusses the efficacy of this treatment modality.MethodsA case of pediatric facial papilloma treated with CO2 laser ablation was reported, and the benefits of this treatment modality were reviewed and analyzed in the context of the existing literature.ResultsUnder general anesthesia, the lesional tissue of the left lip was excised, and the pathological diagnosis was confirmed to be maxillofacial papilloma. The lesions were surgically ablated in stages using a CO2 laser, and erythromycin ointment was applied to the treated areas after surgery. A total of three rounds of CO2 laser treatment were performed. The child had no complications during or after the operations; the child’s facial appearance was significantly improved, and there was no sign of recurrence during the 6-month follow-up.ConclusionsThe CO2 laser was useful for resection of this patient who had pediatric facial papillomatosis, and it can restore an aesthetic facial soft tissue profile without significant residual facial deformity. The CO2 laser can achieve precise vaporization resection of diseased tissue with minimal blood loss and a good cosmetic result.
The settlement of tax disputes by the International Court of Justice
Authors: Braumann Céline 
Published: May 2023

AbstractThis article analyses the ICJ, one of the most eminent actors of the international legal regime, as an actor of the international tax regime. So far, the ICJ’s role in tax dispute resolution has been a blind spot in the literature.The descriptive part of this article first discusses the case law of the PCIJ and ICJ that considers – albeit incidentally – questions of taxation. These tax-related cases are categorized as (i) ‘wrongful taxation’ constituting the subject matter of the dispute; (ii) taxation as evidence for a ‘genuine link’ between the state and a national; or (iii) taxation as an ‘effectivité’ to prove the de facto exercise of state authority over a given territory.The second half of the descriptive analysis assesses the Court’s jurisdiction over tax disputes. Tax treaties usually lack compromissory clauses. Yet, there are a number of jurisdictional bases that vest the Court with the competence to sit over hypothetical tax treaty disputes, although certain reservations may render the Court’s jurisdiction residual to other means of tax dispute settlement. Further, Article 344 TFEU possibly precludes EU member states from initiating ICJ proceedings concerning tax treaty disputes with other EU states.The second, normative part of this article contemplates the Court as a future ‘World Tax Court’. It briefly addresses (i) possible effects of the ICJ’s hypothetical involvement in tax disputes; (ii) whether the ICJ might have a future role in tax dispute settlement in light of recent developments; and (iii) whether it is even desirable to involve the Court in tax disputes.
