Look Before You Leap: Economics of Being an Omnichannel Retailer

This paper investigates how the market gets segmented when an omnichannel retailer enters a market hitherto served by non-omnichannel retailers. The added value derived from the omnichannel flexibility is expected to draw more customers to an omnichannel retailer, luring them away from the incumbent non-omnichannel peers. However, the customers are expected to be heterogeneous in their valuation of the omnichannel flexibilities offered. Also, since acquiring omnichannel flexibility entails additional costs for service integration, the omnichannel aspirant is expected to charge a higher price from the customers than its non-omnichannel competitors. Our model considers both these factors, and derives analytical expression for the expected market share of the omnichannel retailer as a function of the price charged by the non-omnichannel peers, the extent of flexibility provided, and the cost of providing the same. Also, given the cost of service integration, we estimate the level of flexibility that an omnichannel retailer must offer if it wants to acquire a specific market share. The findings indicate that the associated integration cost imposes a restriction on the maximum market share an omnichannel entrant can aspire to capture.
Shallow–Deep Convolutional Network and Spectral-Discrimination-Based Detail Injection for Multispectral Imagery Pan-Sharpening

Pan-sharpening is a significant task in remote sensing image processing, which merges a high-resolution panchromatic (PAN) image and a low-resolution multispectral (MS) image to create a high-resolution MS image. In this article, we propose a novel deep-learning-based MS image pan-sharpening method that combines a shallow–deep convolutional network (SDCN) and a spectral discrimination-based detail injection (SDDI) model. SDCN consists of a shallow network and a deep network, which can capture mid-level and high-level spatial features from PAN images. SDDI, inspired by the “Amélioration de la Résolution Spatial par Injection de Structures” concept, is developed to merge the spatial details extracted by SDCN into MS images with minimal spectral distortion. SDCN and SDDI are collaboratively learned for achieving high-spatial-resolution MS image and preserving more spectral information. Both the visual assessment and the quantitative assessment results on IKONOS and QuickBird datasets confirmed that the proposed method outperforms several state-of-the-art pan-sharpening methods.
Advertising a Desired Change: When Process Simulation Fosters (vs. Hinders) Credibility and Persuasion

Ads promising a desired change are ubiquitous in the marketplace. These ads typically include visuals of the starting and ending point of the promised change (“before/after” ads). “Progression” ads, which include intermediate steps in addition to starting and ending points, are much rarer in the marketplace. Across several consumer domains, the authors show an ad-type effect: progression ads foster spontaneous simulation of the process through which the change will happen, which makes these ads more credible and, in turn, more persuasive than before/after ads (Studies 1–3). The authors also show that impairing process simulation and high skepticism moderate the ad-type effect (Studies 4–5). Finally, they show effect reversals: if consumers focus on achieving the desired results quickly, and it is possible to do so, progression ads and the associated process simulation backfire in terms of credibility and persuasion (Studies 6–7). These findings contribute to existing research by identifying conditions under which progression ads have beneficial or disadvantageous effects. These findings have managerial implications because they run counter to current marketing practices, which favor before/after over progression ads.
Enrichissement de protéines ubiquitinées et une nouvelle approche protéomique pour l'identification des sites d'ubiquitination

The ubiquitin pathway is involved in a wide range of cellular events including receptor intemalization, signal transduction and prote as omal degradation. Misregulation of the later can cause many diseases such as cancer and inflammatory disorders. So far, few large-scale studies of protein ubiquitylation have been reported due to the difficulty of isolating these low abundance and rapidly degraded proteins. In this study, a differential proteomic strategy combining affinity purification and the use of a deubiquitylating enzyme (UBP) is proposed to identify ubiquitylated proteins targeted for proteasomal degradation. Two affinity purifications methods were developed, onebased on a protein binding ubiquitylated proteins (Rad23) and the other based on a modified version of ubiquitin (6xHis-ubiquitin). Combination of both purification methods was also evaluated. These purifications methods enabled the identification of more than 1400 potentially ubiquitylated proteins and 28 sites of ubiquitylation with 6 sites on ubiquitin. A differential proteomic approach was then applied by treating half of the enriched ubiquitylated proteins with UBP. The non-treated control and the UBP-treated prote in extracts were digested with trypsin and analyzed by nanoLC/LC-MS/MS on a high resolution LTQ-Orbitrap mass spectrometer. Peptide ions derived from ubiquitylated proteins comprise a miscleavage tryptic site harbouring a characteristic diglycine adduct on the lysine side chain. Comprehensive data mining and clustering analyses on peptide maps using in-house bioinformatics software were performed to characterize two distinct ion populations representing peptides containing or not the diglycine adduct. Validation of the approach enabled the identification of 3 peptide ion pairs correlated with the addition of an ubiquitylation site.
Expression profiling of genes in BeWo cells following forskolin induced differentiation

Differentiation of the BeWo cell line derived from human choriocarcinoma has been widely used as an in vitro model for studying trophoblast fusion and differentiation. In the present study, we have monitored gene expression changes in differentiating BeWo cells using differential display RT-PCR and microarray analysis. Following 72 hrs of 10 M forskolin treatment, DD RT-PCR analysis showed the differential regulation of several transcripts. The differential expression of these transcripts was also confirmed by RT-PCR and northern blot analysis. Microarray analysis revealed the up-regulation of hCG, hCS, Secretory Leucocyte Protease Inhibitor (SLPI) and down regulation of PCNA and Cyclin D1, thus validating the experimental system. Furthermore, several candidate genes that could influence trophoblast differentiation, cell adhesion and cellular proliferation were identified. Genes involved in cellular proliferation include cyclin M3, replication factor 3, signal-induced proliferation-associated gene 1, osteonectin, clusterin, etc clearly indicating a growth-arrested phenotype for the differentiating BeWo cells. Genes that regulate the invasive behaviour of trophoblasts include MMP2, cathepsin K, cystatin B, SLPI and cysteine-rich angiogenic inducer 61, etc. The co-ordinated regulation of proteases and protease inhibitors suggests that these genes play an important role under in vivo conditions in the regulation of trophoblast invasion at the uterine-placenta interface in vivo. Trophoblastic differentiation associated genes included adipose differentiation-related protein, GADD45A, PPAR binding protein, galectin 3, tubulins, collagen, stathmin, etc. These results suggest the usefulness of this model to understand the molecular mechanism of proliferation, invasion and differentiation of placental cells.
Super tough poly(lactic acid) blends: a comprehensive review

Poly(lactic acid) or poly(lactide) (PLA) is a renewable, bio-based, and biodegradable aliphatic thermoplastic polyester that is considered a promising alternative to petrochemical-derived polymers in a wide range of commodity and engineering applications. However, PLA is inherently brittle, with less than 10% elongation at break and a relatively poor impact strength, which limit its use in some specific areas. Therefore, enhancing the toughness of PLA has been widely explored in academic and industrial fields over the last two decades. This work aims to summarize and organize the current development in super tough PLA fabricated via polymer blending. The miscibility and compatibility of PLA-based blends, and the methods and approaches for compatibilized PLA blends are briefly discussed. Recent advances in PLA modified with various polymers for improving the toughness of PLA are also summarized and elucidated systematically in this review. Various polymers used in toughening PLA are discussed and organized: elastomers, such as petroleum-based traditional polyurethanes (PUs), bio-based elastomers, and biodegradable polyester elastomers; glycidyl ester compatibilizers and their copolymers/elastomers, such as poly(ethylene-co-glycidyl methacrylate) (EGMA), poly(ethylene-n-butylene-acrylate-co-glycidyl methacrylate) (EBA-GMA); rubber; petroleum-based traditional plastics, such as PE and PP; and various biodegradable polymers, such as poly(butylene adipate-co-terephthalate) (PBAT), polycaprolactone (PCL), poly(butylene succinate) (PBS), and natural macromolecules, especially starch. The high tensile toughness and high impact strength of PLA-based blends are briefly outlined, while the super tough PLA-based blends with impact strength exceeding 50 kJ m−2 are elucidated in detail. The toughening strategies and approaches of PLA based super tough blends are summarized and analyzed. The relationship of the properties of PLA-based blends and their morphological parameters, including particle size, interparticle distance, and phase morphologies, are presented.
The role of host-based color and fluorescent pigments in photoprotection and in reducing bleaching stress in corals

Coral tissue colors result from both the intracellular symbiotic dinoflagellates and the host's cellular pigments. The brownish colors are due to the symbionts' photosynthetic pigments; and the bright purple-blue and fluorescent colors produced by the coral host are proteins closely related to Green Fluorescent Protein (GFP). One of the documented biological functions of GFP-like pigments in corals is light optimisation. When light is excessive, GFPs reduce symbiont photoinhibition and photo-damage to coral tissues. We explored the ecological roles of coral coloration and found that spectral properties of GFP-like pigments of many common, shallow reef corals match the absorption of dinoflagellate pigments and demonstrate strong evidence for their photoprotective function by absorbing high energy, damaging solar radiation, dissipating excess energy via fluorescence and by overall photon removal/deflection. A survey of the depth-related distribution of fluorescent and purple-blue color-morphs further confirmed the role of GFPs in photoprotection. These color-morphs were most abundant at high-light shallow depths and their numbers dropped with increasing depths. However, at deeper sites, numbers of fluorescent color-morphs increased, suggesting a reversal of GFP function from sunscreening to that of light amplification in light-limited habitats. We also examined the degree of bleaching damage in different color-morphs during and following the 2002 mass bleaching event. We found that low-GFPpigmented morphs had significantly higher degrees of damage to their symbionts, especially to photosynthesis and a higher degree of partial colony mortality than in high-GFP-pigmented morphs. These results further substantiate earlier findings that GFP-like pigments reduce photoinhibition and the severity of bleachingrelated physiological damage of corals.
Disturbance Extraction for Burst Detection in Water Distribution Networks Using Pressure Measurements

Pipe bursts in water distribution networks cause considerable water losses and lead to potential environmental hazards. Effective burst detection methods enable water companies to repair broken pipes in a timely manner and minimize damage and disruption. A data‐driven detection method is developed and proven for real‐time leak and burst detection in water distribution networks. The method uses a unique integration of disturbance extraction and isolation forest techniques to enable detection of subtle burst signals from normally noisy pressure data. Verification and validation progress from synthetic data to the application to real‐life data from large‐scale open networks. The method is shown to generate comparable levels of detection, with low false positive rates, to other published techniques but without the need to introduce closed valves and expensive flow meters of district meter area structures and the loss of resilience these cause. The method offers the potential to effectively detect bursts from pressure data alone, helping to better manage the distribution of increasingly stressed water resources through aging pipe networks.
Bilingual verbs in three Spanish/English code-switching communities

Objectives/research questions: We investigate two understudied bilingual compound verbs that have been attested in Spanish/English code-switching; namely, ‘hacer + VInf’ and ‘estar + VProg’. Specifically, we examined speakers’ intuitions vis-à-vis the acceptability and preferential use of non-canonical and canonical hacer ‘to do’ or estar ‘to be’ bilingual constructions among bilinguals from Northern Belize, New Mexico and Puerto Rico. Methodology: Speakers from Northern Belize (n = 44), New Mexico (n = 32) and Puerto Rico (n = 30) completed a two-alternative forced-choice acceptability task and a language background questionnaire. Data and analysis: The data were examined using an analysis of variance and Thurstone’s Law of Comparative Judgment. Conclusions: Whereas Northern Belizean bilinguals gave the highest ratings to ‘hacer + VInf’, both groups of US bilinguals gave preferential ratings to ‘estar + VProg’ bilingual constructions. On the other hand, Puerto Rican bilinguals gave the highest preferential ratings to the canonical estar bilingual compound verbs (i.e. estar + an English progressive verb) but rejected hacer bilingual compound verbs. While ‘hacer + VInf’ and ‘estar + VProg’ may represent variants that are available to Spanish/English bilinguals, the present findings suggest a community-specific distribution, in which hacer bilingual compound verbs are consistently preferred over estar bilingual compound verbs in Northern Belize, whereas estar bilingual constructions are preferred among US bilinguals. Originality: This is the first cross-community examination of these bilingual compound verbs in Northern Belize (Central America/Caribbean), New Mexico (Southwest US) and Puerto Rico (US/Caribbean), three contexts in the Spanish-speaking world characterized by long-standing Spanish/English language contact and the use of bilingual language practices. Implications: Findings underscore the importance of bilingual language experience in modulating linguistic competence and the necessity to study code-switching from a language ecological perspective, as subtle context-specific patterns in code-switching varieties may be manifested not only in bilingual speakers’ oral production but in intuition as well. A more fine-grained understanding of speakers’ judgments is vital to experimental studies that seek to investigate code-switching grammars both within and across communities where code-switching varieties of the same language pair are spoken.
PREVALENCE OF TRICHOMONAS VAGINALIS AMONG PREGNANT WOMEN ATTENDING ANTENATAL CLINIC IN TWO HEALTH FACILITIES WITHIN KADUNA METROPOLIS, KADUNA, NIGERIA

Trichomoniasis being referred to as the most prevalent sexually transmitted infection of both male and female urogenital organs. This study was aimed at determining the prevalence of Trichomonas vaginalis among pregnant women attending antenatal at Sabon Tasha General Hospital (STGH) and Yusuf Dantsoho Memorial Hospital (YDMH) who were not on any treatment for sexually transmitted infection for 30 days prior to the period of this research. A total of four hundred and five (405) pregnant women consisting of two hundred and one (201) and two hundred four (204) from Sabon Tasha General Hospital and Yusuf Dantsoho Memorial Hospital respectively, were involved in the study between the periods of September 2019 to January 2020. Socio-demographic information such as age and marital status were obtained from all participating women within the age range of 15-43 years. The prevalence of trichomoniasis 25(6.17%) and 9(4.48%) for YDMH and STGH respectively was observed. Although the highest rate of trichomoniasis infection was recorded in age group of sexually active women (26-30), the prevalence of trichomoniasis in this study was not significantly affected by age and marital status (P>0.05). However, the variation of infection rate between the two health facilities in this study is an indication that the prevalence rate of trichomoniasis varies with location, nature of hygiene, sexual habit and level of education of the individual. The study advocates for sexual and health education at every antenatal clinic and routine screening for trichomoniasis among pregnant and women of reproductive age in order to curb the outbreak of the disease.
Seed viability and dormancy in roly poly (Salsola tragus L.) populations.

Salsola tragus is a summer annual weed found throughout Australia. The characteristics of the seed bank, including seed viability and dormancy, were investigated for populations from the south-west of Western Australia. Seed bank characteristics were investigated for seeds that are released from the mature plants as well as for seeds that remain attached. Average seed viability ranged from 40% to less than 2% for seed collected at plant maturity. Seed viability levels were the same for attached seed and released seed, but a higher proportion of attached seeds were dormant. The portion of dormant seed produced was also variable between populations, and was higher for plants in stressful environments.
The tricuspid valve in review: anatomy, pathophysiology and echocardiographic assessment with focus on functional tricuspid regurgitation

The tricuspid valve (TV) is a complex anatomical structure that incorporates a saddle-shaped annulus, asymmetric leaflets, the subvalvular apparatus and the right ventricle and its loading conditions. In this paper, an appreciation of the normal anatomy and physiology of the TV is reviewed before discussing functional tricuspid regurgitation (TR), a disease that has garnered renewed interest due to increased awareness of adverse outcomes and novel transcatheter therapeutic options. Two and three-dimensional echocardiographic imaging of the TV using transthoracic and transesophageal windows are subsequently discussed. The future of cardiovascular medicine will have more to offer the “forgotten” right-sided chambers and valves, and this review aims to refresh knowledge and enthusiasm around the forgotten but crucially important TV.
Musiikin suomalainen tagaus Bandcamp-artistifoorumilla

Tässä artikkelissa tarkastelemme suomalaisten harrastaja-musiikintekijöiden tapoja asiasanoittaa (tagata) omaa musiikkiaan Internetin Bandcamp-palvelussa. Kuvaamme heidän asiasanavalintojaan, motiivejaan ja näkemyksiään sanavalintojen hyödyllisyydestä potentiaalisille kuuntelijoille. Tutkimuksen pohjana on 67 verkkokyselyyn saatua määrällistä ja laadullista vastausta. Tuloksena havaitaan, ettei selkeä enemmistö artisteista käyttänyt juuri lainkaan aikaa musiikkinsa genretai sisällönkuvailuun ja ettei artistien iällä, koulutusasteella tai statuksella ollut merkitystä tagien valintaan. Toisaalta lähes kaikki vastaajat myös käyttivät joitakin ulkoisia lähteitä sisällönkuvailuunsa ja pyrkivät markkinointietujen hakemisen sijasta täsmällisyyteen. Keskeisimmäksi tekijäksi nousi musiikin löydettävyys, mutta noin viidennes vastaajista ilmoitti myös hakeneensa jotakin tiettyä estetiikkaa, kuten esimerkiksi huumoria tai ”asennetta” valinnoillaan. He eivät pitäneet itseään erityisen osaavina sisällönkuvaajina, mutta silti vain alle neljännes vastaajista edes harkitsi asiasanojensa vaihtamista uusiin. Analysoimalla avointa, käyttäjälähtöistä asiasanoitusta, artikkeli tuottaa uutta tietoa sekä sisällönkuvailun että folksonomioiden tutkimukselle.
Optimization of Extended Phase-Shift Control for Full-Bridge CLLC Resonant Converter With Improved Light-Load Efficiency

The capacitor–inductor–inductor–capacitor (CLLC) resonant converters are drawing more and more attention for their superiority in soft switching, wide output range, and symmetrically bidirectional operation. However, CLLC converter still suffers the problems of unsatisfactory voltage regulation and low efficiency under light-load conditions. Therefore, this article proposes an optimization for extended phase-shift (EPS) control in full-bridge CLLC resonant converter to improve the light-load efficiency. In order to study the relations between phase-shifts of EPS control and converter efficiency, a detailed circuit model is first established to solve the voltage gain, time-domain expressions of main circuit variables, and root mean square (rms) values of resonant currents. Then, a comprehensive loss evaluation is conducted by calculating and analyzing the main power losses, including conduction loss, switching loss, and core losses of magnetic components. Besides, zero voltage switching conditions of primary and rectifier switches are derived to define the range of soft switching. Finally, based on these analyses, the optimal combination of phase-shifts for EPS control is determined to achieve the maximum conversion efficiency of full-bridge CLLC converter at light-load conditions. The validity of the proposed optimized EPS control is verified on a 18∼25 V/400 V, 200 W GaN-based CLLC resonant converter prototype.
