When does it pay to invest in pricing algorithms?
Authors: Wang Xin , Li Xi , Kopalle Praveen K. 
Published: December 2022

AbstractNowadays, firms frequently use big data and pricing algorithms to offer consumers personalized prices according to their willingness to pay. Advances in information technologies have further facilitated the use of customized pricing, which we consider an important facet of transformative marketing. At the outset, personalized pricing may appear to reduce the asymmetry of information between the firm and consumers, and benefits the firm but hurts consumers. To investigate this view, we consider a novel setting in which consumers must incur search costs to make an informed purchase from the firm. Contrary to conventional wisdom, we find that personalized pricing can sometimes make both the firm and consumers better off, thus leading to a win–win situation. We also show that an imperfect pricing algorithm can outperform a perfect one, thereby explaining why certain retailers like Amazon are adopting imperfect pricing algorithms. On the one hand, a moderately reliable pricing algorithm gives high‐preference consumers a chance to be misclassified as low‐preference consumers and obtain a low price, thereby encouraging consumer search. On the other hand, a highly reliable pricing algorithm significantly reduces consumers' surplus, which stifles consumer search. As a result, both firm profit and consumer surplus can be nonmonotone in the reliability of the algorithm. To the best of our knowledge, this is the first paper that documents the effect of personalized pricing under consumer search.
From the AKNS system to the matrix Schrödinger equation with vanishing potentials: Direct and inverse problems
Authors: Demontis Francesco , van der Mee Cornelis 
Published: December 2022

AbstractWe relate the scattering theory of the focusing AKNS system with vanishing boundary conditions to that of the matrix Schrödinger equation. The corresponding Miura transformation, which allows this connection, converts the focusing matrix nonlinear Schrödinger (NLS) equation into a new nonlocal integrable equation. We apply the matrix triplet method to derive the multisoliton solutions of the nonlocal integrable equation, thus proposing a new method to solve the matrix NLS equation.
Dermoscopy and reflectance confocal microscopy‐augmented characterization of pigmented micro‐basal cell carcinoma (less than 2 mm diameter)
Authors: Foltz Emilie , Ludzik Joanna , Witkowski Alexander 
Published: December 2022

AbstractBackgroundBasal cell carcinoma (BCC) is the most common skin cancer, accounting for approximately 80% of nonmelanoma skin cancer diagnoses each year. Among other factors, the staging of BCC is influenced by its measured diameter. Stage 1 BCC is defined as a lesion measuring 2 cm across or less. Of note, there have been increasing publications reporting features of “small‐sized” BCCs, which can present smaller than 1 mm. However, few of these studies have characterized features of pigmented small‐sized BCC. The application of in‐vivo imaging such as dermoscopy and reflectance confocal microscopy (RCM) allows for the non‐invasive distinction of these lesions from benign and malignant melanocytic neoplasms, thereby reducing unnecessary biopsies.MethodsWithin one year, three patients presented to Oregon Health and Science University's dermatology clinic with pigmented lesions of concern measuring less than 2 mm that were histologically confirmed as pigmented BCC. We sought to characterize the features of these lesions in a case series with the non‐invasive imaging modalities of dermoscopy and RCM.ResultsAll cases presented clinically as a small, brown, macule on the face. Each of the three cases exhibited differing features on dermoscopy. With the application of RCM, we were able to visualize characteristic BCC features, prompting removal by shave biopsy.ConclusionTo our knowledge, no other study has reported dermoscopic and RCM features of a cohort of pigmented BCCs 2 mm in diameter or smaller. We propose to define BCCs of this size as micro‐BCCs. The variability of dermoscopic findings observed in our study, combined with the small size of these pigmented lesions, shows the utility of RCM as a non‐invasive diagnostic tool for pigmented micro‐BCCs.

Published: December 2022

AbstractThe benefits of manure as a source of nutrients for plants and to improve soil quality are well‐known. Monitoring of manure application is needed if environmental issues are to be prevented. In particular, the availability and accumulation of phosphorus (P) has to be subject to rigorous monitoring. This study aims to both evaluate the efficacy of the resin method in extracting inorganic labile P in soils under the long‐term application of dairy liquid manure (DLM), and verify the influence of DLM on the recovery of applied P and soil legacy P. To realize our objectives, two long‐term field experiments were established under a no‐tillage system with annual DLM application on sandy clay loam (sandy Oxisol) and clayey (clayey Oxisol) soils. Treatment consisted of DLM applications (0, 60, 120, 180 m3 ha−1 year−1), independent of mineral fertilizer. Soil samples were taken from the 0–5, 5–10 and 10–15 cm layers after 10 years from the beginning of the trial. A single extraction with resin underestimated inorganic labile P; however, successive extractions were able to take up 43% and 26% of the total P in sandy and clayey Oxisols, respectively, whereas in a single extraction the take‐up was 17% and 8% from the same soils, respectively. The resin method was more effective in extracting P from the sandy Oxisol. Thus, when interpreting soil P contents for fertilizer planning, the soil texture should be taken into account. DLM application decreased P recovered from applied P, ranging from 54% to 83% (sandy), and 43% to 67% (clayey), and substantially increased soil legacy P.

AbstractWound dehiscence, oftentimes a result of the poor tensile strength of early healing wounds, is a significant threat to the post‐operative patient, potentially causing life‐threatening complications. Vanadate, a protein tyrosine phosphatase inhibitor, has been shown to alter the organisation of deposited collagen in healing wounds and significantly improve the tensile strength of incisional wounds in rats. In this study, we sought to explore the effects of locally administered vanadate on tensile strength and collagen organisation in both the early and remodelling phases of excisional wound healing in a murine model. Wild‐type mice underwent stented excisional wounding on their dorsal skin and were divided equally into three treatment conditions: vanadate injection, saline injection control and an untreated control. Tensile strength testing, in vivo suction Cutometer analysis, gross wound measurements and histologic analysis were performed during healing, immediately upon wound closure, and after 4 weeks of remodelling. We found that vanadate treatment significantly increased the tensile strength of wounds and their stiffness relative to control wounds, both immediately upon healing and into the remodelling phase. Histologic analysis revealed that these biomechanical changes were likely the result of increased collagen deposition and an altered collagen organisation composed of thicker and distinctly organised collagen bundles. Given the risk that dehiscence poses to all operative patients, vanadate presents an interesting therapeutic avenue to improve the strength of post‐operative wounds and unstable chronic wounds to reduce the risk of dehiscence.

Abstract
This paper considers the deformation of Al/B4C and NiTi/TiC composites and 6061T6 aluminum alloy with double-layer composite coatings reinforced by B4C and TiC particles. Three- and two-dimensional dynamic problems are solved numerically using Abaqus/Explicit. The thermomechanical behavior of homogeneous aluminum matrices and substrates is modeled by an isotropic elastic-plastic formulation. The nitinol matrix implies the possibility of a completely reversible elastic phase transition from austenite to martensite upon reaching the critical equivalent strains. The fracture of particles in the composite coating is modeled using the Huber criterion, taking into account the stress mode type. The study also examines the effects of the volume fraction of boron carbide particles and the phase transition in NiTi on the magnitude of residual stresses and strains in composites after cooling and under mechanical loads. The influence of the arrangement of composite layers on the strength of the material with a double-layer coating is evaluated theoretically and experimentally. The results of the experiments qualitatively confirm the simulation results.
The Stable Carbon and Nitrogen Isotope Compositions of Larvae of Burrowing Shrimps (Crustacea: Decapoda: Gebiidea and Axiidea) from Vostok Bay, Sea of Japan
Authors: Kornienko E. S. , Kiyashko S. I. 
Published: December 2022

AbstractLarvae of eight burrowing shrimp species from Vostok Bay, Sea of Japan, were analyzed for their carbon (δ13C) and nitrogen (δ15N) isotope composition. In zoeae I of these species, the δ13C values varied in a range characteristic of planktotrophic organisms, with the average values for larvae of gebiids being lower than for larvae of axiids. The highest δ15N values, comparable to those reported for omnivorous zooplankton, were recorded from larvae ofLeonardsaxius amurensisandBoasaxius princeps. The dominance of phytoplankton in the diet of zoeae I ofNihonotrypaea makaroviwas indicated by the low δ15N values close to the nitrogen isotope ratio of particulate organic matter. According to the nitrogen isotope composition, the larvae of threeUpogebiaspecies and twoNihonotrypaeaspecies held an intermediate position (with δ15N values ranging from 6.2 to 6.4‰). It was found that the diet of the studied burrowing shrimp larvae does not depend on the taxonomic position, and food preferences differ markedly even in zoeae of congener species, which should be taken into account when cultivating decapod larvae under laboratory conditions.

ObjectivesTo develop a breast cancer risk prediction model for Chamorro and Filipino women of the Mariana Islands and compare its performance to that of the Breast Cancer Risk Assessment Tool (BCRAT).DesignCase–control study.SettingClinics/facilities and other community-based settings on Guam and Saipan (Northern Mariana Islands).Participants245 women (87 breast cancer cases and 158 controls) of Chamorro or Filipino ethnicity, age 25–80 years, with no prior history of cancer (other than skin cancer), residing on Guam or Saipan for at least 5 years.Primary and secondary outcome measuresBreast cancer risk models were constructed using combinations of exposures previously identified to affect breast cancer risk in this population, population breast cancer incidence rates and all-cause mortality rates for Guam.ResultsModels using ethnic-specific relative risks performed better than those with relative risks estimated from all women. The model with the best performance among both ethnicities (the Breast Cancer Risk Model (BRISK) model; area under the receiver operating characteristic curve (AUC): 0.64 and 0.67 among Chamorros and Filipinos, respectively) included age at menarche, age at first live birth, number of relatives with breast cancer and waist circumference. The 10-year breast cancer risk predicted by the BRISK model was 1.28% for Chamorros and 0.89% for Filipinos. Performance of the BCRAT was modest among both Chamorros (AUC: 0.60) and Filipinos (AUC: 0.55), possibly due to incomplete information on BCRAT risk factors.ConclusionsThe ability to develop breast cancer risk models for Mariana Islands women is constrained by the small population size and limited availability of health services and data. Nonetheless, we have demonstrated that breast cancer risk prediction models with adequate discriminatory performance can be built for small populations such as in the Mariana Islands. Anthropometry, in particular waist circumference, was important for estimating breast cancer risk in this population.

IntroductionDespite various tobacco control measures in Japan, smoking remains a leading cause of mortality. This manuscript outlines proposed methodology for scoping review that aims to describe the knowledge gaps for local-level smoking cessation interventions in Japan, their implementation barriers and facilitators, and the use of implementation strategies.Methods and analysisA scoping review will be conducted using the updated guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses-extension for Scoping Reviews to systematically search peer-reviewed journal articles and grey literature to identify studies on smoking cessation interventions in Japan. The six-stage scoping review model will involve (1) identifying the research question; (2) identifying relevant studies; (3) selecting studies; (4) charting data; (5) collating, summarising and reporting the results; and (6) consultation exercise. Since there is little information available on the implementation context in the literature, we will use grey literature to identify organisations implementing smoking cessation interventions and conduct a cross-sectional survey among them to supplement the information gap. Based on a literature review, findings will be organised on smoking cessation interventions in local settings (ie, communities, workplaces, schools and hospitals) at the population, provider and individual levels in Japan to understand knowledge gaps. We will adopt the consolidated framework for implementation research to identify implementation barriers and facilitators, and the expert recommendations for implementing change to identify implementation strategies.Ethics and disseminationThis study does not require ethical committee approval. The scoping review method will be robust in searching available smoking cessation interventions in Japan. The findings of this study will be compiled as case studies of best practices on smoking cessation interventions and disseminated to relevant stakeholders at the public and private levels through publications, presentations in conferences and stakeholder meetings.

IntroductionThe revascularisation strategy for lower limb atherosclerosis obliterans (ASO) remains controversial. In this meta-analysis, we will summarise existing evidence to compare the long-term and short-term outcomes between endovascular revascularisation and open revascularisation for patients with ASO.MethodsRelevant randomised controlled trials (RCTs) and cohort studies are included from the following databases: MEDLINE/PubMed, Embase and the Cochrane Library. The last search time is 1 August 2022. Two reviewers will independently identify RCTs and cohort studies according to eligibility and exclusion criteria. The risk of bias of included cohort studies, and RCTs are assessed with the Newcastle-Ottawa Scale, Methodological Index of Non-randomized Studies and Cochrane Collaboration’s tool, respectively. The primary outcomes include overall survival, amputation-free survival and 30-day mortality. TSA Beta Software V.0.9.5.10 is used to perform the trial sequential analysis for primary outcomes. The Grades of Recommendations, Assessment, Development and Evaluation (GRADE) tool will be used to assess the level of evidence for outcome from RCTs. Stata V.17.0 software is used to pool primary outcomes.Ethics and disseminationThis study will be disseminated through peer-reviewed journals or conference reports. No ethical approval requirements are required because the results presented in this study are conducted based on published data.PROSPERO registration numberCRD42022359591
Additional operation rates after surgery for degenerative spine diseases: minimum 10 years follow-up of 4705 patients in the national Swedish spine register
Authors: Joelson Anders , Sigmundsson Freyr Gauti 
Published: December 2022

ObjectivesTo identify rates of additional operation after the index operation for degenerative lumbar spine diseases.DesignRetrospective register study.SettingNational outcome data from Swespine, the National Swedish spine register.ParticipantsA total of 4705 patients who underwent one-level surgery for degenerative disk disease (DDD) or lumbar spinal stenosis (LSS) with or without degenerative spondylolisthesis (DS) between 1 January 2007 and 31 December 2010 were followed from 1 January 2007 to 31 December 2020 to record all cases of additional lumbar spine operations.InterventionsOne-level spinal decompression and/or posterolateral fusion for degenerative spine diseases.Primary outcome measuresNumber of additional operations.ResultsAdditional operations were more common at adjacent levels for patients with LSS with DS treated with decompression and fusion whereas additional operations were more evenly distributed between the index level and the adjacent levels for DDD treated with fusion and LSS with and without DS treated with decompression only. For patients younger than 60 years, treated with decompression and fusion for LSS with DS, the additional operations were evenly distributed between the index level and the adjacent levels.ConclusionsThere are different patterns of additional operations following the index procedure after surgery for degenerative spine diseases. Rigidity across previously mobile segments is not the only important factor in the development of adjacent segment disease (ASD) after spinal fusion, also the underlying disease and age may play parts in ASD development. The findings of this study can be used in the shared decision-making process when surgery is a treatment option for patients with degenerative lumbar spine diseases as the first operation may be the start of a series of additional spinal operations for other degenerative spinal conditions, either at the index level or at other spinal levels.

Published: December 2022

This study reports on the exploration of the phosphinoboration reaction with several thiosemicarbazones (R5R4NC(S)NR3N=CR1R2). Reactions between either Ph2PBpin (pin = 1,2-O2C2Me4) or Ph2PBcat (cat = 1,2-O2C6H4) with thiosemicarbazones containing a terminal primary or secondary amine afforded boron-containing heterocyclic 1,3,4-thiadiazoline products in excellent yield. The addition of Ph2PBpin to thiosemicarbazones containing an NMe2 group in the terminal position generated novel five-membered heterocycles in moderate yield, which included boron, sulfur, and nitrogen atoms. Heterocyclization of the thiosemicarbazones occurs preferentially in the presence of functional groups such as acetyl and pyridyl groups.
Growth of perturbations in Tsallis and Barrow cosmology
Authors: Sheykhi Ahmad , Farsi Bita 
Published: December 2022

AbstractWe report the effects of entropic corrections to the Friedmann equations on the growth of perturbations in the early stages of the universe. We consider two types of corrections to the area law of entropy, known as Tsallis and Barrow entropy. Using these corrections to entropy, we derive the modified Friedmann equations and explore the growth of perturbations in a flat universe filled with dark matter (DM) and the cosmological constant. We employ the spherically symmetric collapse formalism and work in the linear regime for the perturbations. Interestingly enough, we find that the profile of density contrast is quite different from the standard cosmology in Tsallis and Barrow cosmology. We observe that the growth rate of matter perturbations crucially depends on the values of Tsallis and Barrow parameters. By increasing these entropy correction parameters, the total density contrast increases as well. This implies that perturbations grow faster in a universe with modified entropy-corrected Friedmann equations.

Using the Automated Calibration Unit (ACU) and the Cable Loop System (CLS), multiple radioactive sources are deployed to various positions in the TAO detector for energy calibration. The residual non-uniformity can be controlled within 0.2%. The energy resolution degradation and energy bias caused by the residual non-uniformity can be controlled within 0.05% and 0.3%, respectively. The uncertainty of the non-linear energy response can be controlled within 0.6% with the radioactive sources of various energies, and could be further improved with cosmogenic $$^{12}{\textrm{B}}$$
