Massage-Inspired Haptic Device for Interpersonal Connection in Long-Distance Communication

The use of tactile senses in mediated communication has generated considerable research interest in past decades. Since massage is a common practice in Asian cultures, we propose to introduce massage-based interactions in mediated communication between people in a close relationship. We designed a device for distant interactive massage to be used during online conversation and we assessed its effect on interpersonal connection with eight pairs of Chinese participants in romantic relationships. All pairs were asked to engage in a conversation, either through a video call or through a massage-assisted video call. The findings showed that the use of the massage device significantly increased the perceived emotional and physical connection between the users. The results also showed a significant increase in the engagement in the massage activity, e.g., total massage time and average force per finger, from positive conversation to negative conversation, demonstrating an evidence of the interplay between audio-visual and haptic communication. Post hoc interviews showed the potential of the massage device for long-distance communication in romantic relationships as well as in parents-children relationships.

Plantas aquáticas em ambientes antropizados e naturais: perspectivas filogenéticas

Com base na correlação esperada, de que condições antrópicas reduzem a diversidade filogenética, este estudo comparou assembleias de plantas aquáticas, naturais e antropizadas, a fim de perceber tal padrão. Para isso, foram calculadas métricas filogenéticas para testar a hipótese, recorreu-se ao teste de Mantel entre a diversidade filogenética e a distância geográfica das áreas analisadas, fez-se uma análise de similaridade para determinar as conexões florísticas, além da detecção das síndromes de dispersão dos táxons avaliados. Como resultados, observou-se que, apesar de as áreas naturais e antropizadas apresentarem diferença significativa em termos de riqueza, são compostas pelas mesmas famílias e gêneros botânicos, ou seja, independentemente do status de conservação da área ou da distância geográfica. Há aceitação de um modelo nulo, em que o sucesso da dispersão dos grupos avaliados foi determinante para a explicação dos fatos.
The Clinical Value of Multimodal Ultrasound for the Differential Diagnosis of Hepatocellular Carcinoma from Other Liver Tumors in Relation to Histopathology

Recent advances in the field of ultrasonography offer promising tools for the evaluation of liver tumors. We aim to assess the value of multimodal ultrasound in differentiating hepatocellular carcinomas (HCCs) from other liver lesions. We prospectively included 66 patients with 72 liver tumors. The histological analysis was the reference standard for the diagnosis of malignant liver lesions, and partially for benign tumors. All liver lesions were assessed by multiparametric ultrasound: standard ultrasound, contrast-enhanced ultrasound (CEUS), the point shear wave elastography (pSWE) using shear wave measurement (SWM) method and real-time tissue elastography (RTE). To diagnose HCCs, CEUS achieved a sensitivity, specificity, accuracy and positive predictive value (PPV) of 69.05%, 92.86%, 78.57% and 93.55%, respectively. The mean shear-wave velocity (Vs) value in HCCs was 1.59 ± 0.29 m/s, which was lower than non-HCC malignancies (p < 0.05). Using a cut-off value of 1.58 m/s, SWM achieved a sensitivity of 54.76%, and 82.35% specificity, for differentiating HCCs from other malignant lesions. The combination of SWM and CEUS showed higher sensitivity (79.55%) compared with each technique alone, while maintaining a high specificity (89.29%). In RTE, most HCCs (61.53%) had a mosaic pattern with dominant blue areas corresponding to type “c” elasticity. Elasticity type “c” was 70.59% predictive for HCCs. In conclusion, combining B-mode ultrasound, CEUS, pSWE and RTE can provide complementary diagnostic information and potentially decrease the requirements for other imaging modalities.
Enhancing 3GPP CAPIF Authentication and Authorization Across Mobile Operators Using OpenID Connect and Single Sign-On

A key enabler for vertical businesses to adopt the 5G networking paradigm is the introduction of Network Applications as the horizontal middleware layer between 5G operators and vertical applications. The Network Application ecosystem allows reliable and secure interaction between the control plane of mobile operators and the various vertical businesses, in a standardised way defined by the Common API Framework. Although the framework's security features and mechanisms ensure robust communication between mobile operators and vertical applications, they cannot sustain the rapidly evolving Network Application marketplaces, which require seamless onboarding, authentication and authorization of Network Applications across multiple mobile operators. The paper investigates the security enhancements of incorporating the OpenID Connect protocol in the Common API Framework standard and supporting the single sign-on authentication scheme for Network Applications across different Common API Framework instances. The work, which builds on top of the EU funded EVOLVED-5G, aims on a robust and distributed solution using open-source protocols for authentication and authorization, incorporating security-as- a-service features for 5G and beyond network implementations.
Bioactivity-Guided Isolation and Antihypertensive Activity of Citrullus colocynthis Polyphenols in Rats with Genetic Model of Hypertension

Background and Objectives: Citrullus colocynthis belongs to the Cucurbitaceae family and is a wild medicinal plant used in folk literature to treat various diseases. The purpose of the current study was to explore the antihypertensive and antioxidant potentials of Citrullus colocynthis (CC) polyphenol-rich fractions using a spontaneous hypertensive rat (SHR) model. Materials and Methods: The concentrated aqueous ethanol extract of CC fruit was successively fractioned using solvents of increasing polarity, i.e., hexane, chloroform, ethyl acetate and n-butanol. The obtained extracts were analyzed for total phenolic content (TPC), total flavonoid content (TFC) and total flavonol content (TOF). Moreover, the CC extracts were further evaluated for radical scavenging capacity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assays and antioxidant activity using inhibition of linoleic acid peroxidation and determination of reducing potential protocols. The phytochemical components were characterized by HPLC–MWD–ESI–MS in positive ionization mode. Results: The results showed that ethyl acetate fraction (EAF) exhibited a higher content of phenolic compounds in term of TPC (289 mg/g), TFC (7.6 mg/g) and TOF (35.7 mg/g). EAF showed higher antioxidant and DPPH and ABTS scavenging activities with SC50 values of 6.2 and 79.5 µg/mL, respectively. LCMS analysis revealed that twenty polyphenol compounds were identified in the EAF, including phenolic acids and flavonoids, mainly myricetin and quercetin derivatives. The in vivo antihypertensive activity of EAF of CC on SHR revealed that it significantly decreased the mean arterial pressure (MAP), systolic blood pressure (SBP), diastolic blood pressures (DBP) and pulse pressure (PP) as compared to normal and hypertensive control groups. Moreover, EAF of CC significantly reduced the oxidative stress in the animals in a dose-dependent manner by normalizing the levels of superoxide dismutase (SOD), malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NOx) and total antioxidant capacity (TAC). Furthermore, the treatment groups, especially the 500 mg of EAF per kg body weight (EA-500) group, significantly (p ≤ 0.05) improved the electrocardiogram (ECG) pattern and pulse wave velocity (PWV). Conclusion: It was concluded that the EAF of CC is a rich source of polyphenols and showed the best antioxidant activity and antihypertensive potential in SHR.
Exploration of the Biocontrol Activity of Bacillus atrophaeus Strain HF1 against Pear Valsa Canker Caused by Valsa pyri

Valsa pyri-induced pear Valsa canker is among the most prevalent diseases to impact pear quality and yields. Biocontrol strategies to control plant disease represent an attractive alternative to the application of fungicides. In this study, the potential utility of Bacillus atrophaeus strain HF1 was assessed as a biocontrol agent against pear Valsa canker. Strain HF1 suppressed V. pyri mycelium growth by 61.20% and induced the development of malformed hyphae. Both culture filtrate and volatile organic compounds (VOCs) derived from strain HF1 were able to antagonize V. pyri growth. Treatment with strain HF1-derived culture filtrate or VOCs also induced the destruction of hyphal cell membranes. Headspace mixtures prepared from strain HF1 were analyzed, leading to the identification of 27 potential VOCs. Of the thirteen pure chemicals tested, iberverin, hexanoic acid, and 2-methylvaleraldehyde exhibited the strongest antifungal effects on V. pyri, with respective EC50 values of 0.30, 6.65, and 74.07 μL L−1. Fumigation treatment of pear twigs with each of these three compounds was also sufficient to prevent the development of pear Valsa canker. As such, these results demonstrate that B. atrophaeus strain HF1 and the volatile compounds iberverin, hexanoic acid, and 2-methylvaleraldehyde exhibit promise as novel candidate biocontrol agents against pear Valsa canker.
Application of Particle Filter in Path-loss Modelling

The article presents the dynamic estimation method of the path loss exponent parameter in the function of the distance based on the conducted measurements. A specific feature of this solution is its suitability for distance estimation on devices which are characterised by a small amount of resources. The presented method allows to provide an acceptable precision of distance estimation while using a relatively small measurement set. For this purpose, real RSSI (Received Signal Strength Indicator) measurements were used and estimation of the path-loss exponent was performed with the use of a Bayesian particle filter. The article, apart from a detailed demonstration of the algorithms, presents the results of the sensitivity analysis of this method to change the number of inserted particles and of the repetitions of calculations needed to estimate the path loss exponent. Additionally, the results of the model stability study on the size change of the experimental dataset RSSI are presented. The properties and accuracy of the proposed method are verified based on a set of actual measurement data. All the obtained results indicate the utility of the Bayesian filtering method for effective estimation of the path loss exponent and confirm the possibility of using the described method in systems with a limited amount of computing resources.
US Foreign Policy towards Pakistan, India and Afghanistan (2011-2012): Framing of Pakistani Press

This study provides a detailed quantitative and qualitative analysis of coverage of Pakistani press regarding US policy towards Pakistan, Afghanistan and India in the context of war against terrorism from January 2011 to December 2012. All unsigned editorials appeared in The News and Dawn examined by applying content analysis method containing themes related to US policy towards Pakistan such as: Drone attacks and USAID to Pakistan; US policy towards Afghanistan and US policy towards India. The study maintains that both Dawn & The News were critical to US policy towards Pakistan regarding Drone Attacks but the tone of The News was intense in nature. Moreover, the Dawn supported US policy to provide USAID to Pakistan, while The News was critical to it. On US policy towards India, The News supported the US policy to maintain friendly relations with India despite of Kashmir issue. On US policy towards Afghanistan, The News framed a negative picture of US while Dawn adopted a balance stance. The pattern of coverage supports the argument that the press and foreign policy relationship is issue-specific and it also has linked with media organization’s policy. This study also asserts that on foreign policy issues press framing is not necessarily influenced by country’s defined foreign policy objectives.
Biofilm development on new and cleaned membrane surfaces.

This thesis presents a comprehensive research report on microbiological aspects of biofouling occurrence in full-scale reverse osmosis (RO) systems. Biofouling is a process in which microorganisms attach to membranes and develop into a thick film that can choke the entire RO system. Management of this problem requires basic understanding of the mechanism of this phenomenon. The basic questions of this PhD research project therefore addressed the origin, succession and spatiotemporal development of biofilms in full-scale RO systems, in particular in relation to operational aspects of RO systems. The multifaceted research strategy involving acquisitions of representative samples and use of many molecular and microscopic analysis techniques in parallel was employed. The investigation showed that biofilms are able to grow on any surface in a full-scale RO plant. This gives local niches for detachment of biomass, either as single cells or cell clumps, and results in a spreading of bacteria to the further stages of the plant. In the RO membrane modules, the enriched bacteria might more easily colonise the surfaces since they will be better adapted to growth in the system than bacteria present in the feed water. Initially, the single cell colonizers (sphingomonads) form a number of flat and abundantly EPS-embedded cell monolayers over the entire membrane surface. The clumps-associated pioneers (mainly Beta- and Gammaproteobacteria) appear to be trapped mainly in the first part of the module, most likely due to a filtering action of the spacer. In time, these bacteria develop in pillar-like structures and slowly spread throughout the whole membrane module on top of the established sphingomonads biofilm. The secondary colonisers (bacteria and eukaryotes) occur in the resulting biofilm formations. Although composition of the biofilm microbial community undergoes a succession in time, the architecture of an established biofilm appears to be rather stable. Conventional treatment of RO membrane modules with chemicals did not lead to cleaning: the sphingomonads cells can be detected under the collapsed but obviously not removed biofilm EPS matrix. After cleaning, the biofouling layer seemed to grow faster (within 6 days) than a fresh biofilm (16 days). To conclude, biofouling is a complex phenomenon with two appearances: a fouling layer on the membrane limiting the water flux and a fouling layer on the spacer limiting the water flow through the spacer channel and resulting in an increased pressure drop. It became clear that cleaning strategies should focus more on the removal of accumulated biomass and not only on the killing of cells. Moreover, the basal Sphingomonas layer requires further research to appropriately control biofouling in RO systems. It might also be possible to design the RO - membrane module in a different manner, leading to a different biofilm morphology which gives less rise to operational problems.
Collaborative Governance dalam Pembangunan Masyarakat Perbatasan di Kabupaten Merauke

The development of border areas aims to realize the border paradigm as the homeland of the Republic of Indonesia and needs to be carried out comprehensively, in the sense not only through a welfare approach but also through a security and environmental approach. For this reason, collaborative governance is one of the concepts that can be applied in developing border areas. This research was conducted using a descriptive method and a qualitative approach in Sota District, which is an area directly adjacent to Papua New Guinea. The results of the study indicate that collaborative governance in the development of the RI-PNG border area in the Sota District has not gone well. Indicators of starting conditions and intermediate outcomes have been seen from several programs such as the formation of community groups for Pokos honey entrepreneurs, eucalyptus oil processors, and ant nest tea processors. However, when viewed from the indicators of the collaborative process and institutional design, there has not been an ideal collaboration between the government, the private sector, and universities. Where it can be seen that all community empowerment activities are still dominated by the government, in this case, the Regional Border Management Agency, the Natural Resources Conservation Center, the Wasur National Park Center, and Merauke Regency. Ideally, in a collaborative process, universities and the community should be involved as implementers and balancers of the programs provided by the government in improving the welfare of the community.
