Learning Cross-Modal Deep Embeddings for Multi-Object Image Retrieval using Text and Sketch

This is the author accepted manuscript. The final version is available from IEEE via the DOI in this recordIn this work we introduce a cross modal image retrieval system that allows both text and sketch as input modalities for the query. A cross-modal deep network architecture is formulated to jointly model the sketch and text input modalities as well as the the image output modality, learning a common embedding between text and images and between sketches and images. In addition, an attention model is used to selectively focus the attention on the different objects of the image, allowing for retrieval with multiple objects in the query. Experiments show that the proposed method performs the best in both single and multiple object image retrieval in standard datasets.European Union Horizon 2020CERCA Programme/Generalitat de Cataluny

Performance of lactating crossbred cows fed on forage based total mixed ration

A study was conducted to evaluate the forage based total mixed ration (TMR) in crossbred lactating cows on milk production and nutrient digestibility. TMR was prepared by mixing wheat straw, chapped green forages (sorghum and rice bean in experiment I and oat and berseem in experiment II) and concentrate feed having 17 percent dietary CP. Two feeding experiments for the period of 60 days duration each during rainy (experiment I) and winter seasons (experiment II) were conducted in first lactating crossbred cows. In both the experiment six first lactating cows were taken and divided into 2 groups. Group 1 (T1)was fed TMR and in Group 2 (T2) ingredients were fed separately. The total daily dry matter intake (DMI) in cows fed TMR increased significantly (p˂0.01) by 15.92 percent in experiment I, when multi cut sorghum and rice bean used as green fodder. However, the differences were negligible in experiment II,when oat and berseem used as green fodder. The dry matter (DM) and crude protein (CP) digestibility as well as digestible energy (DE) value of ration were increased significantly (p˂0.01) in cows fed on TMR based on berseem and oat as green fodder in experiment II. However, differences were non-significant in experiment I, when multi cut sorghum and rice bean used as green fodder in TMR. The overall increase in milk production was recorded by 16.96 and 19.49 percent in cows fed TMR during experiment I and II, respectively. Similarly, an increase in milk production in cows fed different feeds separately was also recorded 10.74 and 6.41 percent,respectively during experiment I and II. Thus, it i s concluded that feeding of TMR is beneficial for proportionate intake of all feed ingredients, overall feed intake and better digestibility of nutrients resulting into higher milk production.

Brexit or Brand it? The Effects of Attitude Towards Brexit and Reshored Brands on Consumer Purchase Intention

Copyright © 2022 The Authors. Brexit has caused a seismic shift in the British socio-economic and political landscapes, creating widespread uncertainties, while simultaneously giving hope and national pride to millions. The decision by a number of organizations to reshore their production has opened a new era for business management that challenges the axiomatic assumption of the benefits of offshored production. Although reshoring predates Brexit, the link between the two in the British context is not just serendipitous and they are argued to have reasonable interlinkages. However, there is inadequate empirical evidence to suggest that British consumers’ attitude towards Brexit has any effect on their intention to purchase reshored brands. Through a mixed-methods study comprising a survey of 415 respondents and 20 in-depth interviews, this paper addresses this research gap. Findings suggest that corporate social responsibility (CSR) and consumer reshoring sentiment (CRS) have positive effects on consumers’ attitude towards reshored brands. Despite CRS's positive influence on attitude towards Brexit, the latter does not have any significant effects on the intention to purchase a reshored brand, which is positively influenced by the attitude towards the same brand. As such, companies should enhance the image of their brands and CSR in order to harness the benefits of reshoring.University of Western Australia, as part of the Wiley – The University of Western Australia agreement via the Council of Australian University Librarians

A study of empyema thoracis and role of intrapleural streptokinase in its management

BACKGROUND: Clinical spectrum, microbiology and outcome of empyema thoracis are changing. Intrapleural instillation of fibrinolytic agents is being increasingly used for management of empyema thoracis. The present study was carried out to describe the clinical profile and outcome of patients with empyema thoracis including those with chronic empyema and to study the efficacy and safety of intrapleural streptokinase in its management. METHODS: Clinical profile, etiological agents, hospital course and outcome of 31 patients (mean age 40 ± 16 years, M: F 25: 6) with empyema thoracis treated from 1998 to 2003 was analyzed. All patients were diagnosed on the basis of aspiration of frank pus from pleural cavity. Clinical profile, response to therapy and outcome were compared between the patients who received intrapleural streptokinase (n = 12) and those who did not (n = 19). RESULTS: Etiology was tubercular in 42% of the patients (n = 13) whereas the rest were bacterial. Amongst the patients in which organisms could be isolated (n = 13, 42%) Staphylococcus aureus was the commonest (n = 5). Intrapleural streptokinase was instilled in 12 patients. This procedure resulted in increase of drainage of pleural fluid in all patients. Mean daily pleural fluid drainage after streptokinase instillation was significantly higher for patients who received intrapleural streptokinase than those who did not (213 ml vs 57 ml, p = 0.006). Only one patient who was instilled streptokinase eventually required decortication, which had to be done in five patients (16.1%). Mean hospital stay was 30.2 ± 17.6 days whereas two patients died. CONCLUSIONS: Tubercular empyema is common in Indian patients. Intrapleural streptokinase appears to be a useful strategy to preserve lung function and reduce need for surgery in patients with late stage of empyema thoracis

The paper identifies and analyses customers’ motives to co-create when interacting with smart services by integrating the self-determination theory with coordination mechanisms. The study also examines the how and to what extent value co-creation impacts on word-of-mouth and customer-based brand equity. An online questionnaire was employed for empirically validating the research model. The relationships were examined using partial least square path modelling. The findings show that intrinsic and extrinsic motives are significant antecedents of value co-creation. The coordination mechanisms namely, relating and knowing also significantly influence customers’ involvement in the value co-creation process. Results also show that value co-creation mediates the relationship between customers motives (intrinsic and extrinsic) to co-create and consequences. Findings of this study adds to the human–computer interaction literature by strengthening the nomological network of value co-creation when interacting with smart services by proposing a novel model integrating both the antecedents and outcomes of value co-creation. By recognizing how this practice could be motivated, service providers can bolster customer-firm interactions and enable favourable firm level consequences.Open Access funding enabled and organized by CAUL and its Member Institutions

The Jacob2 Lectin of the Entamoeba histolytica Cyst Wall Binds Chitin and Is Polymorphic

For many years, we and others have used cysts of Entamoeba invadens (Ei), a reptilian parasite, to model the infectious and diagnostic cysts of the human pathogen Entamoeba histolytica (Eh). The Ei cyst wall is composed of chitin fibrils, as well as Jacob and Jessie lectins that have unique chitin-binding domains. Our recent results suggest a “wattle and daub” model of the Ei cyst wall, where the wattle or sticks (chitin fibrils bound by multivalent Jacob lectins) is constructed prior to the addition of the mortar or daub (self-aggregating Jessie3 lectins). Here we “humanize” the Ei model of the cyst wall with four findings. First, a recombinant Eh Jacob2 lectin, which has three predicted chitin-binding domains surrounding a large spacer domain, binds chitin beads. Second, polymorphisms in the spacer domain of EhJacob2 discriminate clinical isolates of Entamoeba. Third, chitinase, Jacob2 lectin, and Jessie3 lectin are present in cyst walls of clinical isolates of Entamoeba. Finally, numerous sera from patients infected with Entamoeba recognize recombinant Eh Jacob1 and Jessie3 lectins

Back reaction effects on the dynamics of heavy probes in heavy quark cloud

We holographically study the effect of back reaction on the hydrodynamical properties of $\mathcal{N} = 4$ strongly coupled super Yang-Mills (SYM) thermal plasma. The back reaction we consider arises from the presence of static heavy quarks uniformly distributed over $\mathcal{N} = 4$ SYM plasma. In order to study the hydrodynamical properties, we use heavy quark as well as heavy quark-antiquark bound state as probes and compute the jet quenching parameter, screening length and binding energy. We also consider the rotational dynamics of heavy probe quark in the back-reacted plasma and analyse associated energy loss. We observe that the presence of back reaction enhances the energy-loss in the thermal plasma. Finally, we show that there is no effect of angular drag on the rotational motion of quark-antiquark bound state probing the back reacted thermal plasma.Comment: 29 pages, 21 figure

Loss of Cannabinoid Receptor CB1 Induces Preterm Birth

Preterm birth accounting approximate 10% of pregnancies in women is a tremendous social, clinical and economic burden. However, its underlying causes remain largely unknown. Emerging evidence suggests that endocannabinoid signaling via cannabinoid receptor CB1 play critical roles in multiple early pregnancy events in both animals and humans. Since our previous studies demonstrated that loss of CB1 defers the normal implantation window in mice, we surmised that CB1 deficiency would influence parturition events.Exploiting mouse models with targeted deletion of Cnr1, Cnr2 and Ptgs1 encoding CB1, CB2 and cyclooxygenase-1, respectively, we examined consequences of CB1 or CB2 silencing on the onset of parturition. We observed that genetic or pharmacological inactivation of CB1, but not CB2, induced preterm labor in mice. Radioimmunoassay analysis of circulating levels of ovarian steroid hormones revealed that premature birth resulting from CB1 inactivation is correlated with altered progesterone/estrogen ratios prior to parturition. More strikingly, the phenotypic defects of prolonged pregnancy length and parturition failure in mice missing Ptgs1 were corrected by introducing CB1 deficiency into Ptgs1 null mice. In addition, loss of CB1 resulted in aberrant secretions of corticotrophin-releasing hormone and corticosterone during late gestation. The pathophysiological significance of this altered corticotrophin-releasing hormone-driven endocrine activity in the absence of CB1 was evident from our subsequent findings that a selective corticotrophin-releasing hormone antagonist was able to restore the normal parturition timing in Cnr1 deficient mice. In contrast, wild-type females receiving excessive levels of corticosterone induced preterm birth.CB1 deficiency altering normal progesterone and estrogen levels induces preterm birth in mice. This defect is independent of prostaglandins produced by cyclooxygenase-1. Moreover, CB1 inactivation resulted in aberrant corticotrophin-releasing hormone and corticosterone activities prior to parturition, suggesting that CB1 regulates labor by interacting with the corticotrophin-releasing hormone-driven endocrine axis

Salinity reduces site quality and mangrove forest functions. From monitoring to understanding

Mangroves continue to be threatened across their range by a mix of anthropogenic and climate change-related stress. Climate change-induced salinity is likely to alter the structure and functions of highly productive mangrove systems. However, we still lack a comprehensive understanding of how rising salinity affects forest structure and functions because of the limited availability of mangrove field data. Therefore, based on extensive spatiotemporal mangrove data covering a large-scale salinity gradient, collected from the world's largest single tract mangrove ecosystem – the Bangladesh Sundarbans, we, aimed to examine (QI) how rising salinity influences forest structure (e.g., stand density, diversity, leaf area index (LAI), etc.), functions (e.g., carbon stocks, forest growth), nutrients availability, and functional traits (e.g., specific leaf area, wood density). We also wanted to know (QII) how forest functions interact (direct vs. indirect) with biotic (i.e., stand structure, species richness, etc.) and abiotic factors (salinity, nutrients, light availability, etc.). We also asked (QIII) whether the functional variable decreases disproportionately with salinity and applied the power-law (i.e., Y = a Xᵇ) to the salinity and functional variable relationships. In this study, we found that rises in salinity significantly impede forest growth and produce less productive ecosystems dominated by dwarf species while reducing stand structural properties (i.e., tree height, basal area, dominant tree height, LAI), soil carbon (organic and root carbon), and macronutrient availability in the soil (e.g., NH4+, P, and K). Besides, species-specific leaf area (related to resource acquisition) also decreased with salinity, whereas wood density (related to resource conservation) increased. We observed a declining abundance of the salt-intolerant climax species (Heritiera fomes) and dominance of the salt-tolerant species (Excoecaria agallocha, Ceriops decandra) in the high saline areas. In the case of biotic and abiotic factors, salinity and salinity-driven gap fraction (high transmission of light) had a strong negative impact on functional variables, while nutrients and LAI had a positive impact. In addition, the power-law explained the consistent decline of functional variables with salinity. Our study disentangles the negative effects of salinity on site quality in the Sundarbans mangrove ecosystem, and we recognize that nutrient availability and LAI are likely to buffer the less salt-tolerant species to maintain the ability to sequester carbon with sea-level rise. These novel findings advance our understanding of how a single stressor—salinity—can shape mangrove structure, functions, and productivity and offer decision makers a much-needed scientific basis for developing pragmatic ecosystem management and conservation plans in highly stressed coastal ecosystems across the globe
