Abstract
Background
Despite the possible traumatic significance of cancer and of the incidence, prevalence, and survival of young women with breast cancer, these patients are underrepresented in multidimensional research. In the present survey, QoL and psychological distress were studied in a sample of young female breast cancer patients during the first year of their disease. More in detail, the study was firstly aimed to assess if QoL of 18–45 years old female breast cancer patients was different from QoL of women from the general population and if it changed over time. Secondly, it described the psychological distress and its change over time. Finally, it assessed if QoL registered 1 year post-surgery may be explained by QoL and/or psychological distress registered during the hospitalization.

Methods
One hundred six, consecutive 18–45 years old, female primary breast cancer patients undergoing anticancer surgery filled out the Short Form 36 Health Survey Questionnaire, the Hospital Anxiety and Depression Scale and a socio-demographic and clinical form during hospitalization to receive surgery (T0), and again at 12 months post-surgery (T1).

Results
At T0, participants showed a better physical functioning (p = 0.001) than the female normative sample, whereas their mental functioning was worse (p < 0.001). In this time, mental functioning within our sample was weaker than physical functioning (p < 0.001). Over time, physical functioning decreased (p < 0.001), whereas mental functioning increased (p < 0.001). Both at T0 and T1, anxiety was higher than depression (p < 0.05). Both distress dimensions decreased over time (p < 0.001). Nevertheless, at T0 the 25.5 and 26.4% of the sample were respectively possible and probable cases of anxiety, whereas the 17.9 and 9.4% were possible and probable cases of depression. At T1, the percentages were 17.9 and 18.9% for anxiety, and 8.5 and 6.6% for depression. In both considered times, a better QoL corresponded to less psychological distress. However, QoL and psychological distress assessed at T0 did not predict the QoL at T1.

Conclusions
This study documented as QoL and psychological distress may change during the first year after surgery for a primary breast cancer in young women; therefore, they should be monitored over time to detect and treat women with alarming levels on them.

Abstract
Background
Little attention has been paid to whether snoring frequency is associated with body composition in menopausal women, particularly in China. This study objected to investigate the association between self-reported snoring and body composition in (peri-post) menopausal Chinese women as well as metabolic indicators.

Methods
This cross-sectional study enrolled 715 participants aged 40–67 years from the Menopause Clinic in the Shanghai Sixth People’s Hospital. Participants were categorized into four subgroups stratified by self-reported snoring frequency: never, rarely (< 1 night per week), occasionally (1–2 nights per week), regularly (≥3 nights per week), while body composition was measured using bioelectrical impedance analysis (BIA). Besides, blood sample were collected to test the glycolipid indicators.

Results
In our sample of investigation, regular snoring (≥3 nights per week) was found to be an independent risk factor for higher fat mass (total, upper limbs, trunk), with the highest risk of 2.4 times for fat mass of trunk after adjusting for metabolic confounders(p = 0.003). Meanwhile, regular snoring was independently associated with higher fat mass (total and each segment) only in menopausal transition (p = 0.023).

Conclusions
We suggested that self-reported regular snoring may be taken as a simple alternative to predict higher fat mass (≥17.11 kg, upper quartile) in menopausal women. Similarly, body composition should be attached to the great importance to those who in menopausal transition in order to help to prevent obstructive sleep apnea (OSA).

Abstract
Background
Fetal anemia is associated with a hyperdynamic circulation and cardiac remodeling. Rapid intrauterine transfusion (IUT) of blood with high hematocrit and viscosity into the umbilical vein used to treat this condition can temporarily further affect fetal heart function. The aim of this study was to evaluate the short-term changes in fetal myocardial function caused by IUT using automated analysis of cine-loops of the fetal heart obtained by color tissue Doppler imaging (cTDI).

Methods
Fetal echocardiography was performed before and after IUT. cTDI recordings were obtained in a four-chamber view and regions of interest were placed at the atrioventricular plane in the left ventricular (LV), right ventricular (RV) and septal walls. Myocardial velocities were analyzed by an automated analysis software to obtain peak myocardial velocities during atrial contraction (Am), ventricular ejection (Sm), rapid ventricular filling (Em) and Em/Am ratio was calculated.
Myocardial velocities were converted to z-scores using published reference ranges. Delta z-scores (after minus before IUT) were calculated. Correlations were assessed between variables and hemoglobin before IUT.

Results
Thirty-two fetuses underwent 70 IUTs. Fourteen were first time transfusions. In the LV and septal walls, all myocardial velocities were significantly increased compared to normal values, whereas in the RV only Sm was increased before IUT (z-scores 0.26–0.52). In first time IUTs, there was a negative correlation between LV Em (rho = − 0.61, p = 0.036) and LV Em/Am (rho = − 0.82, p = 0.001) z-scores and hemoglobin before IUT. The peak myocardial velocities that were increased before IUT decreased, whereas LV Em/Am increased significantly after IUT.

Conclusions
This study showed that peak myocardial velocities assessed by cTDI are increased in fetuses before IUT reflecting the physiology of hyperdynamic circulation. In these fetuses, the fetal heart is able to adapt and efficiently handle the volume load caused by IUT by altering its myocardial function.
Histone acetylation and the role of histone deacetylases in normal cyclic endometrium
Authors: Gujral Palak , Mahajan Vishakha , Lissaman Abbey C. , Ponnampalam Anna P. 
Published: August 2020

AbstractHistone acetylation is a critical epigenetic modification that changes chromatin architecture and regulates gene expression by opening or closing the chromatin structure. It plays an essential role in cell cycle progression and differentiation. The human endometrium goes through cycles of regeneration, proliferation, differentiation, and degradation each month; each phase requiring strict epigenetic regulation for the proper functioning of the endometrium. Aberrant histone acetylation and alterations in levels of two acetylation modulators - histone acetylases (HATs) and histone deacetylases (HDACs) - have been associated with endometrial pathologies such as endometrial cancer, implantation failures, and endometriosis. Thus, histone acetylation is likely to have an essential role in the regulation of endometrial remodelling throughout the menstrual cycle.

Abstract
Background
This study investigated the effects of Islamic religious and breathing techniques with heart rate variability (HRV) biofeedback therapies on HRV and psycho-physiologic coherence (resonance frequency), depression and anxiety in coronary artery bypass graft surgery (CABG) patients.

Methods
Sixty CABG patients were chosen and randomly assigned to religious, breathing techniques and control groups. The experimental groups received 8 weeks of treatments; a 2-h session with home works in each week. The control group received only their normal hospital interventions. The groups’ depression, anxiety, HRV and psycho-physiologic coherence levels were assessed before and after the interventions by DASS-21 for depression and anxiety, and em-wave desktop software for HRV and psycho-physiologic coherence. The data were analyzed using ANCOVA with Bonferroni Comparison test and descriptive tests in SPSS software.

Results
The findings showed that there were significant differences in psycho-physiologic coherence (HRV), depression and anxiety scores among the three groups in the post-tests. In fact, depression and anxiety were reduced more in the religious group, while psycho-physiologic coherence raised more in the breathing with the HRV feedback group.

Conclusion
The results showed that both Islamic religious and breathing techniques with HRV biofeedback therapies can be used in rehabilitation programs for CABG patients in clinics and hospitals.

AbstractMycopathogens are serious threats to the crops in commercial mushroom cultivations. In contrast, little is yet known on their occurrence and behaviour in nature. Cobweb infections by a conidiogenousCladobotryum-type fungus identified by morphology and ITS sequences asHypomyces odoratuswere observed in the year 2015 on primordia and young and mature fruiting bodies ofAgaricus xanthodermusin the wild. Progress in development and morphologies of fruiting bodies were affected by the infections. Infested structures aged and decayed prematurely. The mycoparasites tended by mycelial growth from the surroundings to infect healthy fungal structures. They entered from the base of the stipes to grow upwards and eventually also onto lamellae and caps. IsolatedH. odoratusstrains from a diseased standing mushroom, from a decaying overturned mushroom stipe and from rotting plant material infected mushrooms of different species of the genusAgaricuswhilePleurotus ostreatusfruiting bodies were largely resistant. Growing and grownA. xanthodermusandP. ostreatusmycelium showed degrees of resistance against the mycopathogen, in contrast to mycelium ofCoprinopsis cinerea. Mycelial morphological characteristics (colonies, conidiophores and conidia, chlamydospores, microsclerotia, pulvinate stroma) and variations of five differentH. odoratusisolates are presented. In pH-dependent manner,H. odoratusstrains stained growth media by pigment production yellow (acidic pH range) or pinkish-red (neutral to slightly alkaline pH range).
Bluetooth-based device-to-device routing protocol for self-organized mobile-phone mesh network

Published: August 2020

AbstractThe bluetooth technology provides a point-to-point communication interface to mobile phones and other electronic devices, which can be used to form a self-organized ad hoc mesh network consists of mobile phones. In such a self-organized mesh network, the data packets are not transferred by traditional telecommunication backbone network but through bluetooth-based hop-by-hop routing among mesh nodes in the network. Such an ad hoc mesh network may find a wide span of application scenarios where access to backbone network infrastructure is not available, yet it needs an efficient routing protocol to provide a timely transmission mechanism for data packets to reach their destination even under situations when network topology is in constant changes due to mobile node’s movement. In the bluetooth-based device-to-device routing protocol (BDRP) presented in this paper, we propose several key designs as processed data table, node exclusion by packet and source control routing to provide an end-to-end packet transmission solution in a dynamically changing topology with constraints on network bandwidth, battery power, and storage space on a mobile device. The processed data table and node exclusion by packet mechanisms contribute to eliminating a great number of non-useful duplicate packets in routing path, and the source control routing algorithm implemented with a cross-layer packet retransmission process provides a fast and low-overhead routing policy and an assurance to packet reaching destination. In the simulation experiment conducted BDRP demonstrates its effectiveness and efficiency in eliminating undesirable duplicate packets and adaptability to constant topological changes. The performance comparison experiment indicates that the BDRP outperforms the optimized link state routing (OLSR) protocol in packet arrival rate, particularly under situations when mobile nodes are in fast moving mode, yet manages to maintain the same level of transmission delay as OLSR’s even with the packet retransmission process. The work presented in this paper provides a key technology for the applications of Bluetooth mobile phone mesh network in a larger geographic area and a broader application domain.

S-RASTER: contraction clustering for evolving data streams
Authors: Ulm Gregor , Smith Simon , Nilsson Adrian , Gustavsson Emil , Jirstrand Mats 
Published: August 2020

AbstractContraction Clustering (RASTER) is a single-pass algorithm for density-based clustering of 2D data. It can process arbitrary amounts of data in linear time and in constant memory, quickly identifying approximate clusters. It also exhibits good scalability in the presence of multiple CPU cores. RASTER exhibits very competitive performance compared to standard clustering algorithms, but at the cost of decreased precision. Yet, RASTER is limited to batch processing and unable to identify clusters that only exist temporarily. In contrast, S-RASTER is an adaptation of RASTER to the stream processing paradigm that is able to identify clusters in evolving data streams. This algorithm retains the main benefits of its parent algorithm, i.e. single-pass linear time cost and constant memory requirements for each discrete time step within a sliding window. The sliding window is efficiently pruned, and clustering is still performed in linear time. Like RASTER, S-RASTER trades off an often negligible amount of precision for speed. Our evaluation shows that competing algorithms are at least 50% slower. Furthermore, S-RASTER shows good qualitative results, based on standard metrics. It is very well suited to real-world scenarios where clustering does not happen continually but only periodically.

Published: August 2020

AbstractPoor quality medicines represent an expanding global public health threat facilitated by the Internet. A recent survey showed that one in five students have used modafinil to enhance learning ability mainly purchased from Internet sources. The aim of this work was to develop on-the-spot and simple methods for the quantification of modafinil in generic medicines using Fourier transform-infrared (FTIR), near-infrared (NIR) and Raman spectroscopy along with partial least square regression (PLSR). Modafinil tablets were measured in intact form using NIR and Raman and in powdered form using FTIR, NIR and Raman. Additionally, powder mixtures of crushed modafinil tablets and excipient(s) were prepared either by diluting the crushed tablets with excipient(s), or sequentially adding excipient(s) to the crushed tablets. Three PLSR models were constructed in MATLAB 2014a from powder mixtures and two from intact and powdered tablets. For FTIR and Raman spectroscopy, PLSR models based on tablets gave linear calibration curve with correlation coefficient (r2) values above 0.94 and a root mean square error of calibration (RMSEC) below 0.96% m/m. Conversely, the PLSR model based on powder sequential addition gave the highest accuracy using the NIR spectra (r2= 0.99, RMSEC = 1.15% m/m). The latter model showed accuracy in predicting the concentration of the active pharmaceutical ingredient in modafinil generic medicines proving their authenticity. The overall results showed that the combination of the three spectroscopic methods with PLSR offered a rapid technique for authenticating generic modafinil medicines.
Detection of triggered shallow slips caused by large earthquakes using L-band SAR interferometry
Authors: Fujiwara Satoshi , Nakano Takayuki , Morishita Yu 
Published: August 2020

AbstractInterferograms pertaining to large earthquakes typically reveal the occurrence of elastic deformations caused by the earthquake along with several complex surface displacements. In this study, we identified displacement lineaments from interferograms; some of which occur on the shallow section of seismogenic faults. However, such displacements are typically located away from the hypocenter, and they are considered as triggered shallow slips. We found that the triggered shallow slips had a varied nature, as follows. (1) No evidence has yet been obtained regarding the generation of large seismic motion via triggered shallow slips; thus, their occurrence is seldom considered a cause of major earthquakes. However, we found that a movement of triggered shallow slip associated with an M 6-class earthquake occurred on an active fault that has previously caused an M 7-class earthquake. (2) At certain locations, several parallel displacement lineaments have been discovered. During the Kumamoto earthquake sequence in 2016, the strain created by the main shock and the motion of triggered shallow slips coincided at a specific location, resulting in the creation of parallel triggered shallow slips by the main shock. Conversely, at another location, the movements of the main shock and triggered shallow slips did not match, since the main shock was simply a trigger, whereas the latter parallel triggered shallow slips are likely a means for releasing previously accumulated strain. (3) The fault scaling law—which states that the length and displacement of a fault are proportional—does not hold true for triggered shallow slips. However, the parallel triggered shallow slips show a relationship between horizontal spacing and its displacement. This may be attributed to immobility in deep locations. These results lead to the following conclusions. Large earthquakes tend to trigger shallow slips on the pre-existing faults. Subsequently, these triggered shallow slips release accumulated strain by causing fault motions, which in turn result in displacement lineaments. The occurrence of such passive faulting creates weak, mobile fault planes that repeatedly move at the same location. These triggered shallow slips cause the diversity among active faults as a result.
Understanding the purpose of benefit corporations: an empirical study on the Italian case
Authors: Mion Giorgio , Loza Adaui Cristian R. 
Published: August 2020

AbstractRethinking the traditional understanding of organizational purpose appears to be necessary. A teleological paradigm shift seems to be on its way, changing the focus of attention from considering business organizations as instruments used to generate profits toward a more comprehensive understanding of their purpose and of the benefit they can create for society. Recently, new organizational entities have emerged, accompanied by the renewal of institutional frameworks, among them are benefit corporations. Italy was the first European country to introduce a legal framework to define the benefit corporation as a particular legal entity. The Italian law on the benefit corporations proposes the promotion of firms that pursue the generation of benefit in a responsible, sustainable, and transparent way and considering diverse stakeholders. This paper explores and describes the multidimensional understanding of benefit and purpose of Italian benefit corporations, utilizing qualitative and quantitative content analysis of 94 Italian benefit corporations’ purpose declarations, and providing a deep insight into the purpose declared by benefit corporations. The research highlights a certain vagueness in public declarations of the purpose of benefit corporations, even though it is clear that they attempt to differentiate themselves from traditional businesses by focusing on social objectives more than on economic ones. Furthermore, normative compliance emerged, but further normative requirements seem to be needed to make more effective the transformative potentiality of benefit corporations and to avoid risks of opportunistic behaviors.
