Relationship between seepage water volume and total suspended solids of landslide dam failure caused by seepage: an experimental investigation
Authors: Dhungana Prakash , Wang Fawu 
Published: April 2020

Abstract
Background
Landslide dams inevitably demonstrate the potential for catastrophic failure with high-risk damage to life and property at the downstream site. Hence, knowledge of the internal stability of dam materials is a key to predicting the seepage failure of landslide dams. In this study, experiments were conducted to examine the relationship between seepage volume and total suspended solids (TSS) of seepage water based on hydro mechanical constrains. Understanding the relationship between the seepage volume and TSS with hydro-mechanical constraints supports the prediction of the seepage failure of landslide dams at the field level.

Result
Experiments were conducted with a mixed sample of silica sands. Seepage water was collected from a flume tank with the facility to measure the hydraulic gradient, vertical displacement, and seepage water volume. Grain size affected the life span of the dam. The seepage volume increased with the increase in the percentage of silica sand S4, whereas TSS increased with the increase in the percentage of silica sand S8. With the increase in the dam height, the dam life decreases for low coeficient of uniformity of the grain size distribution. With the increase in the reservoir size, TSS decreased, and the total seepage volume increased.

Conclusion
Dam failure depends on the particle size, dam geometry, inflow rates, reservoir size, hydraulic gradient, and seepage water volume, and TSS of seepage water. The results indicated that with the increase in fine particles, the life span decreases, and TSS increases. With the increase in the flow rate, the dam life span decreases, and the TSS and seepage volume rate increase.The dam height leads to an increase seepage volume with low TSS, where the life span of the dam also depends on the particle size distribution With the increase in the reservoir size, the seepage water volume decreases with low TSS.

Abstract
Background
Metastasis of renal cell carcinoma (RCC) to the gallbladder is rare, and its clinicopathological feature remains poorly understood. We here present two cases of gallbladder metastasis from RCC presenting as a hypervascular polypoid lesion.

Case presentation
The first case was a 73-year-old man who had undergone right nephrectomy for clear cell RCC. Imaging studies detected a hypervascular polypoid lesion in the gallbladder 6 years after nephrectomy. Laparoscopic cholecystectomy was done. The pathological findings of the polypoid lesion showed proliferation of clear cells in the submucosal layer. Immunohistochemically, the tumor was positive for carbonic anhydrase 9 (CA9) but negative for cytokeratin 7 (CK7), suggestive of metastatic RCC. The second case was a 43-year-old man who had undergone right nephrectomy for clear cell RCC. Imaging studies revealed a hypervascular polypoid lesion of 20 mm in diameter in the gallbladder 1 year after nephrectomy. The patient underwent expanded cholecystectomy and extra-hepatic bile duct resection with lymphadenectomy. Microscopically, the polypoid lesion of the gallbladder was composed of clear cells in the submucosal layer. Immunohistochemical analysis showed positive staining for epithelial membrane antigen (EMA) and carcinoembryonic antigen (CEA) but negative staining for CK7, leading to the diagnosis of metastatic RCC.

Conclusions
Gallbladder metastasis from RCC is rare but should be considered when a hypervascular polypoid lesion in the gallbladder is detected during the follow-up period after RCC treatment.

Abstract
Introduction
Peritonitis is a crucial complication that leads to hospitalization or even death in patients who are undergoing peritoneal dialysis (PD). The incidence of PD-related peritonitis associated with nontuberculous mycobacteria has increased in recent years. However, a well-established treatment for peritonitis is lacking, particularly in peritonitis caused by Mycobacterium abscessus which is a difficult to treat disease due to its inherent resistance to majority of available antibiotics. To the best of our knowledge, this case is the first to report on intraperitoneal multiple nodules that developed due to PD-related peritonitis caused by M. abscessus.

Case presentation
This case reported a case of a 40-year-old female patient who was undergoing PD and who showed multiple intraperitoneal nodules that resembled peritoneal cancer on computed tomography (CT) and that developed after PD-related peritonitis and catheter removal. After multiantibiotic therapy, multiple nodules were found to have disappeared on CT. The nodules continued to disappear and the patient did not show signs of recurrent peritonitis, although there was a possibility of recurrence.

Conclusion
To the best of our knowledge, this case is the first to report on nodules that resembled peritoneal cancer and that developed in the abdominal cavity due to PD-related peritonitis caused by M. abscessus. Positron emission tomography–CT was not useful in distinguishing peritoneal cancer from nodules caused by M. abscessus.

AbstractIntroductionWorldwide, cancer of the breast is the most commonly diagnosed disease and the second leading cause of cancer-related mortality amongst women yearly (Miller et al., 2016). Computer-aided drug discovery (CADD) is a fundamental shortcut in drug discovery arena. CADD tools ascertain key molecule for testing, predicting the effectiveness, the possible side effect, and also assist in upgrading drug-likeliness of drug molecules (Leelananda and Lindert, 2016). The propose of carrying out this research is to design new 2-anilinopyrimidine derivative compounds based on the interaction of the derivative compounds (ligand) and thyroid hormone receptor (TRβ1), and also analyze their pharmacokinetic properties as drug compounds that would be used by the pharmaceuticals against triple-negative breast cancer (MDA-MB-468 cell line).ResultsThree compounds (12, 17, and 18) had the highest docking score ranging from − 7.3 to − 7.4 kcal/mol. This showed that the compounds (ligands) bind tightly with the active site of the thyroid hormone receptor (TRβ1). Based on their tight interactions with the receptor, the compounds were chosen as lead compounds in the design of fourteen new compounds by incorporating some fragments found to bind intensely with the active site of the thyroid hormone receptor (TRβ1). All the newly designed compounds passed the pharmacokinetic analysis (adsorption, distribution, metabolism, excretion, and other physicochemical test) passed the drug-likeness test, and they also adhered to the Lipinski rule of five.ConclusionsNew derivative compounds of 2-anilinopyrimidine against MDA-MB-468 cell line were designed based on the information obtained from the molecular docking studies. Furthermore, the pharmacokinetics analysis (adsorption, distribution, metabolism, excretion (ADME) and other physicochemical properties) carried out on the newly designed compounds showed this compounds can be made into oral drugs for patients with triple-negative breast cancer (MBA-MD-468 cell line) as they serve as most promising inhibitors against thyroid hormone receptor (TRβ1).

Published: April 2020

SummaryDoctors experience high levels of work stress even under normal circumstances, but many would be reluctant to disclose mental health difficulties or seek help for them, with stigma an often-cited reason. The coronavirus disease 2019 (COVID-19) crisis places additional pressure on doctors and on the healthcare system in general and research shows that such pressure brings a greater risk of psychological distress for doctors. For this reason, we argue that the authorities and healthcare executives must show strong leadership and support for doctors and their families during the COVID-19 outbreak and call for efforts to reduce mental health stigma in clinical workplaces. This can be facilitated by deliberately adding ‘healthcare staff mental health support process’ as an ongoing agenda item to high-level management planning meetings.
Broadband dynamically tunable terahertz absorber based on a Dirac semimetal
Authors: Xiong Han , Shen Qi , Ji Qing 
Published: April 2020

In this paper, we propose a broadband tunable metamaterial absorber in the terahertz (THz) region. The absorber comprises a Dirac semimetal film, a dielectric layer, and a gold ground plane. Numerical results show that the absorptivity remains above 90% in the range from 5.7 THz to 8.4 THz when the Fermi level is 65 meV. By varying the Fermi energy of the Dirac semimetal film from 40 meV to 80 meV, the absorption bandwidth and absorption peaks can be dynamically tuned. To explain the mechanism of high absorption, the magnetic field, surface current, and power loss density distributions at different resonant frequencies were presented. Our work may have potential applications in various fields such as sensors, detectors, and photovoltaic devices in THz regions.
Cybersecurity im medialen Diskurs

Published: April 2020

ZusammenfassungDie Digitalisierung hat in den letzten Jahren ein komplexes, sich scheinbar ständig veränderndes Feld möglicher Risiken hervorgebracht, dessen Ausmaße für Unternehmen zunehmend schwer erkennbar sind. Entsprechend wichtig wird die Frage, wie EntscheidungsträgerInnen und MitarbeiterInnen Gefahren im digitalen Raum besser erkennen, adäquat einschätzen und auf diese reagieren können. Da sich EntscheidungsträgerInnen in kleineren KMU meist über Internetrecherchen oder in der Tagespresse über Cybersecurity informieren, hängt ihre Risikoeinschätzung und Maßnahmensetzung davon ab, wie Cybersecurity-Themen in diversen Medien dargestellt und diskutiert werden. Basierend auf einer Diskursanalyse von 504 Medienberichten zum Thema Cybersecurity in Unternehmen zwischen 2010 und 2019 kommt der Beitrag zu dem Ergebnis, dass sich die Medien weniger an langfristig bestehenden Bedrohungslagen orientiert haben, sondern vielmehr an den spektakulärsten Zwischenfällen und typischen Rollenverteilungen zwischen „Gut“ und „Böse“. Insgesamt wurde der Cyberspace als ein unsicherer Raum für Unternehmen dargestellt – teilweise aufgrund des Verhaltens ihrer eigenen MitarbeiterInnen. Für IT-Unternehmen, Polizeibehörden und die Forschung bedeutet der Nachvollzug des medialen Cybersecurity-Diskurses eine verbesserte Einsicht in die selektive und situative Behandlung von Bedrohungslagen durch Medien und die damit verbundenen Verzerrungen unternehmerischer Risikoeinschätzungen. Zentral für die unternehmerische Cybersecurity ist zudem die Kompetenz der MitarbeiterInnen, die Gefahren akkurat erkennen zu können.

Published: April 2020

AbstractA single photon can be coupled to collective charge oscillations at the interfaces between metals and dielectrics forming a single surface plasmon. The electromagnetic near-fields induced by single surface plasmons offer new degrees of freedom to perform an exquisite control of complex quantum dynamics. Remarkably, the control of quantum systems represents one of the most significant challenges in the field of quantum photonics. Recently, there has been an enormous interest in using plasmonic systems to control multiphoton dynamics in complex photonic circuits. In this review, we discuss recent advances that unveil novel routes to control multiparticle quantum systems composed of multiple photons and plasmons. We describe important properties that characterize optical multiparticle systems such as their statistical quantum fluctuations and correlations. In this regard, we discuss the role that photon-plasmon interactions play in the manipulation of these fundamental properties for multiparticle systems. We also review recent works that show novel platforms to manipulate many-body light-matter interactions. In this spirit, the foundations that will allow nonexperts to understand new perspectives in multiparticle quantum plasmonics are described. First, we discuss the quantum statistical fluctuations of the electromagnetic field as well as the fundamentals of plasmonics and its quantum properties. This discussion is followed by a brief treatment of the dynamics that characterize complex multiparticle interactions. We apply these ideas to describe quantum interactions in photonic-plasmonic multiparticle quantum systems. We summarize the state-of-the-art in quantum devices that rely on plasmonic interactions. The review is concluded with our perspective on the future applications and challenges in this burgeoning field.
Self-induced thermo-optical effects in silicon and germanium dielectric nanoresonators
Authors: Tsoulos Ted V. , Tagliabue Giulia 
Published: April 2020

AbstractDielectric nanoresonators uniquely support both magnetic and electric resonances across a wide wavelength range. They are thus being exploited in a growing number of groundbreaking applications. In particular, they have been recently suggested as promising nanoheaters. However, while the thermo-optical properties of silicon and germanium resonators have been exploited to realize tunable metasurfaces based on external thermal inputs, the effect of self-induced optical heating onto their resonances has so far been neglected. In this study, we address the problem of self-heating of a thermo-optical resonator. In particular, employing a recursive procedure to account for the interdependence between the absorption cross section and the temperature of the resonator, we show that self-heating gives rise to a complex, nonlinear relationship between illumination intensity and temperature. Using both analytical and numerical models, we also observe that self-induced optical heating has nonnegligible effects on the spectral position of electric and magnetic resonances of spheres as well as anapole modes of nanodisks, even for moderate illumination intensities relevant for applications such as Raman scattering. Thus, our work demonstrates that self-induced optical heating must be properly accounted for when designing dielectric resonators for a wide range of devices.

Published: April 2020

Abstract
Recent development in nanofabrication technology has enabled the fabrication of plasmonic nanoapertures that can provide strong field concentrations beyond the diffraction limit. Further utilization of plasmonic nanoaperture requires the broadband tuning of the operating wavelength and precise control of aperture geometry. Here, we present a novel plasmonic coaxial aperture that can support resonant extraordinary optical transmission (EOT) with a peak transmittance of ~10% and a wide tuning range over a few hundred nanometers. Because of the shadow deposition process, we could precisely control the gap size of the coaxial aperture down to the sub–10-nm scale. The plasmonic resonance of the SiNx/Au disk at the center of the coaxial aperture efficiently funnels the incident light into the sub–10-nm gap and allows strong electric field confinement for efficient second harmonic generation (SHG), as well as EOT. In addition to the experiment, we theoretically investigated the modal properties of the plasmonic coaxial aperture depending on the structural parameters and correlation between EOT and SHG through finite-difference time-domain simulations. We believe that our plasmonic coaxial apertures, which are readily fabricated by the nanoimprinting process, can be a versatile, practical platform for enhanced light–matter interaction and its nonlinear optical applications.

Published: April 2020

Abstract
This paper presents the thermophysical properties of the 1-butyl-3-methylimidazolium–based ionic liquids (ILs) with different oxidative anions such as hexafluorophosphate and tetrafluoroborate. Differential scanning calorimetry (DSC), thermogravimetric, and rheology studies were carried out for the properties’ measurement. Heating and cooling rates of 1°C/min, 3°C/min, and 5°C/min were used for the DSC analysis. The specific heat capacity of the ILs was measured in the temperature range of −40 to 40°C. The experimental result shows that the specific heat increases with increasing the temperature and the viscosity decreases with increasing the temperature. From the thermogravimetric analysis, the onset temperature of the [BF4] tetrafluoroborate and [PF6] hexafluorophosphate was 362°C and 381°C. Dynamic viscosities of the ILs samples diminished exponentially with an increase in temperature. The density of the ILs samples diminished exponentially with the rising temperature. The electrical conductivity of tetrafluoroborate has the highest electrical conductivity compared to the hexafluorophosphate.
The Philosophy of the Enlightenment as a Paradigm of Transhumanism
Authors: Markuckas Marius 
Published: April 2020

In the works devoted to the phenomenon of transhumanism, it is widely recognized that philosophy of the Enlightenment had a great intellectual influence on the formation of transhumanism. Yet, this article states that the ideas of Enlightenment philosophy can be reasonably treated as not only consisting the conceptual transhumanism core but also as being a source of its internal contradictions. The paper defends the position that transhumanism in general is an intrinsically controversial project and introduces the premises for this contradiction – the basic anthropological views inherited from philosophy of the Enlightenment. Finally, the article questions the status of transhumanism as a techno-scientific program and states it to be an ideologically engaged project in anthropological engineering, which, in its turn, is devoid of any clear theoretical and practical outline.
Machiavelli’s Revolution and Koselleck’s Sattelzeit
Authors: Bustamante Kuschel Gonzalo 
Published: April 2020

This article suggests that human action in Machiavelli is both materialistic and temporalized. It further argues that Reinhart Koselleck’s view of Machiavelli’s understanding of time as historical circularity is misleading. The author is making the case that Machiavelli drew from Lucretian materialism to strip political concepts of content via an animal-materialist anthropology and ontology holding that man, as any animal, is material reality acting under an atomic arrangement wherein no time, whether linear or circular, can exist. The conclusion is that Koselleck’s interpretation of the circularity of time in Machiavelli kept him from seeing his role as an antecedent of the conceptual and temporal revolution underlying the Sattelzeit.

Published: April 2020

OBJECTIVES:
In this study, we evaluate the efficacy of Families Talking Together (FTT), a triadic intervention to reduce adolescent sexual risk behavior.

METHODS:
Adolescents aged 11 to 14 and their female caregivers were recruited from a pediatric clinic; 900 families were enrolled; 84 declined. Families were randomly assigned to FTT or 1 of 2 control conditions. The FTT triadic intervention consisted of a 45-minute face-to-face session for mothers, health care provider endorsement of intervention content, printed materials for families, and a booster call for mothers. The primary outcomes were ever having had vaginal intercourse, sexual debut within the past 12 months, and condom use at last sexual intercourse. Assessments occurred at baseline, 3 months post baseline, and 12 months post baseline.

RESULTS:
Of enrolled families, 73.4% identified as Hispanic, 20.4% as African American, and 6.2% as mixed race. Mean maternal age was 38.8 years, and mean adolescent grade was seventh grade. At the 12-month follow-up, 5.2% of adolescents in the experimental group reported having had sexual intercourse, compared with 18% of adolescents in the control groups (P &lt; .05). In the experimental group, 4.7% of adolescents reported sexual debut within the past 12 months, compared with 14.7% of adolescents in the control group (P &lt; .05). In the experimental group, 74.2% of sexually active adolescents indicated using a condom at last sexual intercourse, compared with 49.1% of adolescents in the control group (P &lt; .05).

CONCLUSIONS:
This research suggests that the FTT triadic intervention is efficacious in delaying sexual debut and reducing sexual risk behavior among adolescents.
Hans Urs von Balthasar and the Christian’s States of Life. Analysis of his Writings in Light of the Creation of the Figure of the Secular Institutes
Authors: Illanes José-Luis 
Published: April 2020

As the subtitle indicates, the article analyzes von Balthasar’s thought on the states of life of christians in light of the creation of the figure of Secular Institutes in 1947 by the Apostolic Constitution Provida Mater Ecclesia. The author highlights the difference between classical thinking on evangelical counsels, based on the search for Christian perfection, and von Balthasar’s view based on the concepts of state of life and form. It underlines the significance of the writings published by von Balthasar in 1948 and 1956 not only to perceive the development of the Swiss theologian’s thought on the states of life, but also to delve -deeper into the consideration of their underlying principles. The author concludes by pointing out the need to arrive at a reflection on holiness in the Church that stems more decisively from the affirmation of the universal call to holiness.
