A novel approach for multimodality medical image fusion over secure environment

An emerging trend to deal with the issue of multimodality medical image fusion over the secure communication environment is required. Hence, this paper presents a human visual fusion algorithm for medical images such as computed tomography and magnetic resonance imaging which is based on the nonsubsampled shearlet transform (NSST) over the secure environment. Initially, the images are decayed through NSST into low and detailed highlights. The neighborhood aggregate of correlation‐based movement measures is proposed to intertwine the low frequency and sum‐modified‐Laplacian‐based fusion is utilized on detail subbands of NSST. After getting a fused image, a method noise thresholding approach is utilized to improve the accuracy of the proposed method. As a result, more accurate fused images is received. To measure the proposed method accuracy, the results of the fused images are also tested over the secure environment where encrypted/decrypted fused images are obtained using the random generator method. These decrypted fused images are also analyzed with original fused images with the proposed method as well as existing methods. From result analysis, it is observed that the proposed technique is better in holding a bone, calcification, cerebrospinal liquid, edema, and tumor subtleties of the source images and is more accurate than other existing fusion methods.
Diet reconstruction in cave bears from craniodental morphology: past evidences, new results and future directions

ABSTRACT The diet of the cave bear (Ursus spelaeus) is a controversial topic, as different paleobiological approaches (e.g. dental wear, isotopic biochemistry, skull morphometrics) result in different dietary inferences for the cave bear, ranging from carnivory to pure herbivory. Here, we review the main results obtained from these approaches, with special emphasis on those obtained from the morphometric analyses of the cave bear craniodental skeleton. Then, we compute a between-group Principal Components Analysis from a set of 3D-landmarks digitized on 103 mandibles of living bears and extinct cave bears and using a phylomorphospace approach. Moreover, we also reconstructed the evolutionary trajectory of the cave bear mandible from the hypothetical shape of its inferred ancestor. Our results indicate that the mandible of the cave bear possess specific traits indicative of a highly-herbivorous diet or, at least, more herbivorous than their closest living relative, the brown bear (Ursus arctos). Moreover, we also propose new directions for future research to obtain more detailed inferences on the potential food resources consumed by the cave bear being crucial to understand the ‘life and death’ of this vanished animal.
Metal-free and stable dye-sensitized polymer matrix for the detoxification of antibiotic drug levofloxacin under visible light illumination

ABSTRACT Herein, we developed novel malachite green (MG), crystal violet (CV), methyl orange (MO) sensitized Polymethylmethacrylate (named as MG@PMMA, CV@PMMA, and MO@PMMA) through the simple solution casting method. The successful formation was confirmed by various analytical and spectroscopic techniques. For the first time, the as-prepared MG@PMMA, CV@PMMA, and MO@PMMA were utilized as photocatalysts for the degradation of levofloxacin (LEV) drug under visible light. The UV–visible spectroscopy results revealed that the above 90%, 94%, and 95% of LEV degradation efficiency was achieved over MG@PMMA, CV@PMMA, and MO@PMMA, respectively. Furthermore, the dye-sensitized PMMA matrices demonstrated good repeatability and reusability even after the fifth usage.
Evaluation of Hepatotoxic effects of Leaves Extract of Cassia italica (Mill.) Lam. ex F.W. Ander (Leguminosae) in Albino Rats

The hepatotoxic effect of aqueous leaves extract of Cassia italica on some liver function parameters was investigated in albino rats. Five groups of the rats were administered the following graded doses of the extract orally: 0, 300, 600, 1500 and 3000 mg/kg bw, for groups 1, 2, 3, 4 and 5 respectively, once daily for 28 days. The serum ALAT, ASAT and ALP levels were found to increase significantly (p<0.05) in all the groups when compared to the control; whereas the serum Albumin levels decreased significantly (p<0.05) in all the groups when compared with the control. There was also a significant increase in Total Bilirubin level (p<0.05) in the groups administered with 3000 and 1500 mg/kg bw, but the reverse was the case in the groups administered with 600 and 300 mg/kg bw of the extract, which showed significant decrease (p<0.05) when compared with the control. These results suggest that, the aqueous leaves extract of Cassia italica has adverse effects on the functional capacities of rat liver. Keywords : Hepatotoxicity, extract, Cassia italic, rats

VARIASI GENETIK MADIDIHANG (Thunnus albacares; Bonnaterre, 1788) DENGAN ANALISIS MIKROSATELIT DI PERAIRAN INDONESIA

Madidihang (Thunnus albacares) merupakan spesies yang bermigrasi jauh yang distribusinya di perairan tropis hingga perairan subtropis. Spesies ini ditemukan di Samudra Atlantik, Hindia dan Pasifik. Informasi genetik ikan dengan migrasi jauh seperti tuna penting diketahui untuk kepentingan pemanfaatan secara lestari. Penelitian ini bertujuan untuk memperoleh informasi keragaman genetik dan struktur populasi yang dieksploitasi dan kekerabatan populasi madidihang di perairan Indonesia. Pengumpulan sampel genetik dilakukan di tiga lokasi yaitu di Barat Sumatra, Selatan Bali dan perairan Sulawesi Utara. Metode yang digunakan adalah analisis mikrosatelit yang terdiri dari ekstraksi, purifikasi, amplifikasi polymerase chain reaction (PCR) dan elektroforesis. Hasil analisis terhadap 3 loci DNA mikrosatelit menunjukkan bahwa tingkat kekerabatan ketiga kelompok sampel relatif dekat yaitu berkisar antara 0,132-0,206. Hal ini menunjukkan bahwa Populasi madidihang di perairan Indonesia merupakan stok tunggal dan terjadi perkawinan acak. Meskipun demikian, sebagai spesies yang bermigrasi jauh lintas negara, pengelolaan madidihang juga memerlukan kerjasama yang baik antar negara yang tergabung dalam organisasi pengelolaan perikanan tuna regional.Yellowfin tuna (Thunnus albacares) is a highly migratory species that distribute from tropical to subtropical waters. This species can be found in the Atlantic, Indian and Pacific Oceans. Genetic information in fish with long distance migration such as tuna is very important for sustainable use. This study aims to obtain information on genetic diversity and population structure exploited and kinship of yellowfin tuna populations in Indonesian waters. Genetic sampling of yellowfin tuna was conducted in three locations in Indonesian waters in western Sumatra, southern Bali and North Sulawesi waters. The methods used was microsatellite analysis which consist of extraction, purification, polymerase chain reaction (PCR) amplification and electrophoresis. The result of 3 microsatellite DNA locus analysis showed that the level of kinship between the three sample groups in Indonesian waters was relatively close, ranging from 0.132 to 0.206. This shows that yellowfin tuna population in Indonesian waters is a single stock and random copulation. However, as a highly migratory species that migrate across the nations, yellowfin tuna management also requires good cooperation among countries incorporated in regional tuna fisheries management organizations.
Factors affecting subsidiary staffing of Japanese multinationals: a panel data analysis

Global staffing is a crucial factor for the success of the overseas operations of multinational corporations (MNCs). This study examines the contextual and organisational factors that affect the localisation of subsidiary staffing in the overseas operations of Japanese multinational companies. Using panel data containing more than 15 000 observations of Japanese overseas subsidiaries and a random-effects logit model, we found that the cultural distance between the home country and the host country has a significant impact on the localisation of subsidiary staffing. In addition, the strategic importance of subsidiaries, as well as the local market orientation and business experiences in the host country, but not research and development (R&D) intensity of Japanese parent firms, have a significant impact on the localisation of foreign subsidiary staffing. We discuss the theoretical and practical implications of these findings.
Development and application of environmental DNA surveillance for the threatened crucian carp (Carassius carassius
)

The crucian carp (Carassius carassius ) is one of few fish species associated with small ponds in the UK. These populations contain genetic diversity not found in Europe and are important to conservation efforts for the species which has declined across its range in Europe. Detection and monitoring of extant crucian carp populations are crucial for conservation success. Environmental DNA (eDNA) analysis could be very useful in this respect as a rapid, cost‐efficient monitoring tool. We developed a species‐specific quantitative polymerase chain reaction (qPCR) assay for eDNA surveillance of crucian carp to enable non‐invasive, large‐scale distribution monitoring. We compared fyke netting and eDNA analysis at ponds with (n = 10) and without (n = 10) crucian carp for presence–absence detection. We examined biotic (crucian carp density represented by catch‐per‐unit‐effort [CPUE] estimate) and abiotic influences on eDNA detection probability using a hierarchical occupancy model, and eDNA quantification using a mixed‐effects model. eDNA analysis achieved 90% detection for crucian carp (n = 10), failing in only one pond where presence was known. CPUE estimate and conductivity had positive and negative influences on eDNA detection probability in qPCR replicates respectively. Similarly, conductivity had a negative effect on DNA copy number, whereas copy number increased with CPUE estimate. Our results demonstrate that eDNA analysis could enable detection of crucian carp populations in ponds and benefit ongoing conservation efforts, but imperfect species detection in relation to biotic and abiotic factors and eDNA workflow requires further investigation. Nonetheless, we have established an eDNA framework for the crucian carp as well as sources of imperfect detection which future investigations can build upon.
Water Use Efficiency‐Based Multiscale Assessment of Ecohydrological Resilience to Ecosystem Shifts Over the Continent of Africa During 1992–2015

The spatial‐temporal representation is a crucial key for understanding at what extent terrestrial ecosystems can maintain their structure and functions and recover from various ecosystem shifts (drought/wet). Hence, it is vital for sustainable ecosystem management, adaptation, and mitigation practices. This study assessed ecohydrological resilience to ecosystem shifts at contrast water‐limited and well‐watered regions at multiple scales (i.e., country scale, basin scale, climate type scale, and land cover scale) over Africa during the period 1992–2015, based on Standard Evapotranspiration Deficit Index (SEDI) and water use efficiency (WUE) at ecosystem scales, which was obtained from satellite‐derived evapotranspiration (ET) and simulated gross primary productivity (GPP) using the Carnegie‐ames‐stanford approaches (CASA) model. SEDI values indicated that 11 years were characterized by dry conditions, while 13 were wetter years during 1992–2015. WUE, ET, and GPP values indicated increased tendencies mostly in central to central west of African continent. The ecohydrological resilience exhibited that about 68.78% of African terrestrial ecosystems were highly, moderately, or slightly resilient, and about 31.22% were not resilient to ecosystem shifts with 11.28% vulnerably exposed to high risk of ecosystem shift and severely nonresilient. The extent areas exposed to severe ecohydrological nonresilience are distributed in Savannas and barelands land cover types, temperate‐dry summer‐hot summer (Csa), climate type, Mediterranean South Coast (B14), African‐North interior (B3), and Red Sea‐Golf of Aden Coast (b5) basins; and the four countries, namely, Egypt, Mauritania, Niger, and Tunisia. These findings may provide insightful scientific information about vulnerable regions for policy making and ecosystem management and increase the necessary awareness for taking reasonable adaptation mechanisms, such as afforesting open lands to increase the area of vegetation cover (i.e., choosing the drought or wet‐tolerant plant species) and water conservation and management measures to ensure the sustainability of terrestrial ecosystems under ecosystem shifts over the African continent.

Political Veganism: An Empirical Analysis of Vegans’ Motives, Aims, and Political Engagement

Scholars increasingly argue that the vegan lifestyle reflects a broader pattern of how political behavior is becoming more individualized and private. Veganism is particularly viewed as an unconventional form of political participation, as it is conducted to address ethical concerns and to change market practices. However, this argumentation lacks detailed empirical data. By means of an original standardized survey of a purposive sample of 648 vegans in Switzerland, this study shows that (1) a vast majority of vegans is politically motivated and aims to induce change in society at large; (2) they are highly engaged in a broad variety of political activities; and (3) politically motivated vegans live vegan more strictly and are more politically active than vegans motivated by personal concerns. This study contributes to the understanding of political participation in current times, and the insights gained may prove useful to vegan movement groups or the food industry.
Disease of Russian sturgeon ( Acipenser gueldenstaedtii ) caused by Aeromonas sp.

In this study, the bacteriological examination was performed to investigate the cause of juvenile sturgeon (Acipenser gueldenstaedtii) mortality, kept in a fish farm, in Turkey. During the disease outbreak, 15% of the sturgeon (2.7-4.2 g) died. The most important clinical signs were swimming upside-down in the water and no feed intake. The fish have exhibited an enlarged abdomen due to the swim-bladder gas problem. Aseptic liver and head-kidney of affected fish were streaked on Tryptic Soy Agar. The pure colonies were characterized by several biochemical tests and rapid commercial test kit (API 20NE). Genetic identification was performed by 16S rRNA gene sequencing. The antibacterial susceptibility of bacteria against six different antibiotics was also evaluated by disk diffusion method. Based on biochemical characteristics, the causative bacteria were identified as Aeromonas hydrophila (API 20NE, profile: 5477754). Bacteria were identified as Aeromonas sp. by molecular analysis. The bacteria were sensitive to enrofloxacin, florfenicol, oxytetracycline, sulfamethoxazole+trimethoprim, gentamycin and resistant to erythromycin. The most effective antibiotics were enrofloxacin and florfenicol. In this study, an infection caused by Aeromonas sp. was reported in Russian sturgeon. Overall this study revealed that Aeromonas sp. may be considered as a causative agent of inflation of the swim bladder in Russian sturgeon.
Preclinical Studies of the Lemon Hill as a Multi-approach Antioxidant and Antidiabetic Plant: Citrus Pseudolimon Tanaka

ABSTRACT The antioxidant and antidiabetic activity of methanol leaves extract (CPMLE) and ethyl acetate fraction (CPEALF) of lemon hill (Citrus pseudolimon) was examined on key enzymes (α-glucosidase and α-amylase) in type-2 diabetes. In-vivo antidiabetic activity was evaluated in streptozotocin (STZ)-induced diabetic rats against CPMLE and CPEALF. Methanolic extract of the plant was effective against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging (IC50 = 313.20 µg mL−1), reducing power (IC50 = 366.69 µg mL−1), and H2O2 scavenging (IC50 = 498.26 µg mL−1) and phosphomolybdate radical scavenging activity (IC50 = 508.02 µg mL−1). Ethyl acetate fraction demonstrated DPPH radical scavenging (IC50 = 259.33 µg mL−1), reducing power (IC50 = 268.91 µg mL−1), and H2O2 scavenging (IC50 = 476.39 µg mL−1) and phosphomolybdate radical scavenging activity (IC50 = 278.60 µg mL−1). C. pseudolimon methanol extract had inhibitory activity against α-glucosidase (IC50 = 350.09 µg mL−1) and α-amylase (IC50 = 291.17 µg mL−1) enzymes. Oral administration of CPMLE and CPEALF reduced elevated fasting blood glucose, lipid levels, and oxidative stress along with Hb1AC level.
Cognitive proximity and innovation performance: are collaborators equal?

PurposeThis paper combines the concepts of search depth and cognitive proximity to investigate the impact of intense collaboration with different external agents on firms' innovation performance. It empirically tests whether firms that draw deeply on cognitively proximate collaborative partners are more innovative than those collaborating intensively with cognitively distant partners. It explores whether the impact of each external agent is equally important in determining the innovation output of firms.Design/methodology/approachUsing data from the Irish Community Innovation Survey 2012–2014, this paper employs a probit model to empirically test the impact of collaboration with cognitively proximate and distant sources of external knowledge to establish whether their impact on innovation performance is uniform.FindingsThe results show that not all collaborators equally impact firm innovation performance. Firms who indicate that knowledge sourced from backward linkages with suppliers is highly important are more likely to engage in both product and process innovation, with the effect more pronounced for the former. The extent of this is greatest for backward linkages compared to forward, horizontal and public linkages. Public linkages have the weakest impact on innovation output which raises questions from a policy perspective given the focus on university–industry collaboration for innovation. The findings indicate that collaboration with cognitively proximate sources of knowledge benefits firms' innovation output.Originality/valueThe study provides empirical evidence on the role of intense collaboration with cognitively proximate and distant external knowledge sources to explore their impact on the subsequent innovation performance of firms. The results can be used to help shape firm-level innovation policy, and indeed national policy, to promote innovation performance.
Immediacy Factors as Solutions to Email Satisfactory Communication Among South-East Nigerian Academic Staff: Structural Equation Modeling and Preliminary Findings

Notwithstanding the evidence of utilizing email among Nigerian academic staff as shown in the previous studies, a recent study demonstrated that they witnessed dissatisfactory communication via email as textbased communication medium. Therefore, the aim of our study was to evaluate if immediacy factors might influence their email satisfactory communication since these factors have been ascertained in the past studies as predictors to satisfactory communications in other asynchronous virtual communications. The respondents’ email satisfactory communication levels were further examined in the study for finding if they also contributed to their email dissatisfactory communication. Hence, a quantitative research method was conducted because the study required both descriptive and inferential studies for the aim of inferring the outcomes to the targeted population. Consequently, our key findings showed that more than half of the respondents’ email satisfactory communication level was not a high one. Additionally, our findings showed that the three immediacy factors which comprised prompt feedback, approachability and similar personality had direct effects on email satisfactory communication. However, similar personality factor contributed most to email satisfactory communication. Therefore, we recommend that they should consider these three immediacy factors, especially the similar personality if they aim to achieve email satisfactory communication. Our findings further explicitly contributed knowledge to asynchronous computer-mediated media satisfactory communication.
