Purpose: Recurrence patterns in rectal cancer patients treated with preoperative chemoradiotherapy (PCRT) are needed to evaluate for establishing tailored surveillance protocol.Methods: This study included 2,215 patients with locally-advanced mid and low rectal cancer treated with radical resection between January 2005 and December 2012. Recurrence was evaluated according to receipt of PCRT; PCRT group (n = 1,258) and no-PCRT group (n = 957). Early recurrence occurred within 1 year of surgery and late recurrence after 3 years. The median follow-up duration was 65.7 ± 29 months.Results: The overall recurrence rate was similar between the PCRT and no-PCRT group (25.8% vs. 24.9%, P = 0.622). The most common initial recurrence site was the lungs in both groups (50.6% vs. 49.6%, P = 0.864), followed by the liver, which was more common in the no-PCRT group (22.5% vs. 33.6%, P = 0.004). Most of the recurrence occurred within 3 years after surgery in both groups (85.3% vs. 85.8%, P = 0.862). Early recurrence was more common in the PCRT group than in the no-PCRT group (43.1% vs. 32.4%, P = 0.020). Recurrence within the first 6 months after surgery was significantly higher in the PCRT group than in the no-PCRT group (18.8% vs. 7.6%, P = 0.003). Lung (n = 27, 44.3%) and liver (n = 22, 36.1%) were the frequent the first relapsed site within 6 months after surgery in PCRT group.Conclusion: Early recurrence within the first 1 year after surgery was more common in patients treated with PCRT. This difference would be considered for surveillance protocols and need to be evaluated in further studies.

Authors: Saborío-Romano Oscar , Bidadfar Ali , Sakamuri Jayachandra Naidu , Zeni Lorenzo , Göksu Ömer , Cutululis Nicolaos Antonio
Published: June 2020

Before diode rectifier (DR) technology for connecting offshore wind
farms (OWFs) to HVdc is deployed, in-depth studies are needed to assess
the actual capabilities of DR-connected OWFs to contribute to the secure
operation of the networks linked to them. This study assesses the
capability of such an OWF to provide communication-less frequency
support (CLFS) to an onshore ac network. It is shown that the HVdc
link’s offshore terminal direct voltage can be estimated from
measurements at the OWF’s point of connection with the DR platform. Two
different methods are proposed for implementing CLFS in the OWF active
power controls. In Method 1, the estimated offshore terminal direct
voltage is used for estimating the onshore frequency deviation. In
Method 2, the actual offshore terminal direct voltage measurement is
used instead. Unique features of the provision of CLFS from OWFs
connected to HVdc via DRs are highlighted, and the dynamic and static
performance of the CLFS control scheme is compared to that of the
communication-based frequency support scheme. To assess the impact of
parameter estimation errors on the provision of CLFS, a parametric
sensitivity study is presented as well, and recommendations are given to
increase accuracy.

The purpose of this study was to determine the effectiveness of extension communication among fisherwomen in the management of eco-tourism. This research was conducted in the tourist area of Benan Island, Lingga Regency, Riau Islands Province, using a mixed method, which is a combination of qualitative and quantitative research methods. The results of the analysis conclude that fisherwomen are said to be effective in conducting extension education to support sustainable eco-tourism management in the village. This is seen from the effectiveness value of several components in the effective category range (330-540), among others the frequency of Extension conducted by fisherwomen to the family environment and surrounding communities has a value of 380, the value of the level of knowledge about the goals of eco-tourism management obtained by the community from extension communication is 370, and the value of implementing sustainable eco-tourism management by the surrounding community of 360. Extension communication methods with individual direct dialogue are considered more effective (380) compared to direct group dialogue (253). This indicates that fisherwomen need a higher intensity of training in order to increase their knowledge and skills as well as their involvement in ecotourism management in the village.
Granice sporów interpretacyjnych w prawoznawstwie

Published: June 2020

Does legal interpretation have borders? Are these borders conventionally established? What makes the given ‘legal reasons’, set forth by certain normative theories of legal interpretation, acceptable in legal discourse (even if the reasons are wrong)? In the present paper, we argue that the notion of the borders of legal interpretation is linked to the general notion of the borders of law. We indicate the scope of ‘interpretive theoretical disagreements’ in law, as discussed by certain new, ‘institutional’ versions of legal positivism. Interpretive borders are not fully determined by the given ‘institutional’ framework. In our view, these borders are also more generally determined inter alia by certain truistic (platitudinous) beliefs related to law and interpretation.

Kompozit malzemelerde kullanılan yüzey plakaları, çekirdek malzemenin cinsi, yoğunluğu, boyutları malzemenin mekanik özelliklerini doğrudan etkilemektedir. Bu çalışmada kompozit sandviç panel malzemesinde çekirdek malzeme olarak farklı kalınlıkta PVC (PoliVinil Klorür) köpük kullanılmıştır. Vakum infüzyon yöntemiyle üretilen PVC köpüklü sandviç panellerin yüzey plakalarında tek yönlü ve çift eksenli karbon fiber kumaşlar kullanılmış, farklı fiber yönlenmelerine sahip panellere eğme ve basma deneyleri uygulanarak yüzey dayanımları karşılaştırılmıştır. Ayrıca, PVC köpükten farklı kalınlıkta çekirdek malzemeler kullanılarak çekirdek kalınlığının çekirdek kayma gerilmesi ve eğilme dayanımı üzerine etkisi araştırılmıştır. Sonuç olarak, panel plakalarında fiber yönlerinin yüzey mukavemetini etkileyen önemli bir parametre olduğu gözlemlenmiştir. PVC çekirdekli sandviç panellerde çekirdek kalınlığının artması sonucu basma ve eğilme dayanımının azaldığı ortaya çıkmıştır.
A MARKOV DECISION PROCESS APPROACH FOR MENTAL HEALTH
Authors: GÖÇGÜN Yasin
Published: June 2020

Mind has various functions such as remembering a certain event, processing information, and providing responses to information it faces. During depression, mind does not work in an efficient way because of wasteful thoughts constantly occupying it. In this paper, we study the problem of how to react during depression, focusing on two decisions: ignoring the effects of wasteful thoughts on mind, and attempting to resolve depression. We model the problem of how to react during depression as a Markov Decision Process and solve it optimally. We also test the performance of two easy-to-use decision rules under diverse scenarios: always ignoring and always attempting to resolve.

DISSIPATION OF THE ACOUSTIC OSCILLATIONS IN TWO-PHASE MEDIUM OF GAS-SOLID PARTICLES TYPE
Authors: Kochergin Anatoly , Pavlov Grigory , Valeeva Ksenia
Published: June 2020

The presented work is devoted to the study of the absorption of acoustic energy by a two-phase medium such as gas-solid particles. An experimental method was chosen for the study the effect on the distribution of acoustic pressure oscillations of various frequencies in a two-phase medium consisting of suspended solids (river sand, various powders, etc.), geometric and physical characteristics of the suspension.
To determine the density of the created two-phase curtain was used capacitive concentration meterthat was developed by the employees of KNRTU-KAI named after A.N. Tupolev. It was also established that with a decrease in the effective diameter of the solid phase, the acoustic resistance of the studied curtain increases at frequencies of more than 800 Hz, while oscillations in the frequency range of 100 ÷ 400 Hz propogate almost unchanged. As a result of interference phenomena, a decrease in sound intensity occurs. Consequently, an increase in the number of particles in the path of wave propogation due to an increase in the amount of suspended matter and the thickness of the curtain contributes to a decrease in the radiation intensity. It has been experimentally proven that the effectiveness of reducing the intensity of acoustic oscillations in a two-phase medium such as "gas-solid particles" increases as a result of:
-increasing the mass content of particles in the medium;
-increasing the thickness of the medium;
- reducing the density and particle size.
To assess the reduction in the intensity of frequency noise when oscillations propogate in a two-phase medium, an empirical dependence was obtained.

Published: June 2020

Our previous study, demonstrated the obesity-resistant phenomenon in the House musk shrew, Suncus murinus (S. murinus). In order to go further to explore the mechanism of the phenomenon of natural obesity resistance in S. murinus, we focused on the effects of diet on fat accumulation and metabolism. In this study, four-week-old male S. murinus were assigned to 1 of 2 experimental groups (n = 6 per group) and fed either a high-fat diet (HFD) or a normal trout diet (NTD) for 24 weeks. Body weight, food ingestion, visceral fat distribution, blood biochemistry and fecal lipids were monitored and analyzed in the HFD and NTD groups. It was found no differences in the average final body weight or body fat change between the two groups. Although animals fed HFD had similar serum triglyceride concentration to animals fed NTD, they had significantly higher phospholipid and total cholesterol concentrations than the NTD group. Furthermore, fecal lipid levels in the HFD group was significantly higher than those in the NTD group, suggesting that diet composition or energy density of the diet affects blood biochemistry. Although NTD-fed S. murinus had higher food ingestion than HFD-fed S. murinus, caloric intake remained almost the same. We speculated S. murinus may suppress obesity and control fat accumulation by controlling calorie intake. These results suggest that the obesity characteristics of S. murinus are not primarily due to dietary factors but to other mechanisms of regulation.

Published: June 2020

The moths that have been recorded in the Glasgow Botanic Gardens, Scotland over the years are reviewed and assessed in the context of the City of Glasgow, the vice-county of Lanarkshire (VC77), and the U.K. in general. The additions to the list since the last review in 1999 are highlighted. Some rare and endangered species are reported, though the comparatively low frequency of sightings of several normally common species suggests that the site is generally under-recorded. The same is true of Glasgow and Lanarkshire in general.

Fact and Fantasy in Byron’s Encounters with Ali Pasha: With a New Byron Letter
Authors: Rizzoli G.B.
Published: June 2020

A new Byron letter to Edward Everett, edited here for the first time, prompts a re-examination of Byron’s stay at Ali Pasha’s court in October 1809. Byron’s visit is analysed in its Ottoman-Albanian cultural context, in an attempt to distinguish the historical facts from the fantasies Byron spun around them.
Pace
Byron’s exaggerated accounts, his reception at Ali’s court had followed the well-established pattern of Western travellers’ visits. Byron was not a diplomatic envoy and he received no special treatment. Byron believed Ali was attracted to him, while Ali thought Byron embodied the despised local stereotype of the effeminate, sexually available boy. The difficulties Byron encountered in the Levant because of his feminine appearance are briefly discussed. The article also identifies key personages Byron met at Ali’s court, confirming the vice-consul Fauvel as the addressee of another Byron letter, and sheds light on Byron’s relationship with Edward Everett.
‘And Making Death a Victory’: Scepticism and Personal Conflict in
Childe Harold’s Pilgrimage
I–II and ‘Prometheus’
Authors: Marchionni Francesco
Published: June 2020

This article explores Byron’s interest in the
hybris
/
nemesis
dichotomy of the Promethean poetic trope in his oeuvre, based on his reading of Aeschylus’s
Prometheus Bound
. Drawing on theories of writing by Nietzsche and Derrida, the article addresses the ways in which the Promethean acts as a supplement of Byron’s poetic selfhood, constructing a discourse of scepticism about poetic truth, and the tragedy of Byron the poet conflicted between creation and destruction. The reading of the past/present dichotomy in
Childe Harold’s Pilgrimage
I–II highlights an early Byronic awareness of the tragic force inhabiting poetry, defacing the illusion of lyrical symbolism. The analysis of ‘Prometheus’ invites a further discussion of Byronic scepticism in light of his meditations on mourning, death and posterity, as well as addressing the ways in which the dramatic pattern of the poem resembles the fragmentation of poetic thought between composition and mental performance.
Lord Byron’s Deformed Foot: A Medical and Biographical Assessment
Authors: Hirschmann J.V.
Published: June 2020

Lord Byron was born with a deformed right foot, which many contemporary accounts suggest was a clubfoot. This congenital affliction consists of several abnormalities that Byron displayed, including a withered calf, short leg, and an inward twisting of the ankle, causing him to walk on the side of his foot rather than on its sole. Other proposed diagnoses do not account for these observations. Byron’s clubfoot did not receive appropriate treatment at an early age, when it might have been corrected. Despite his disability, he became a powerful swimmer, displaying great pride in his accomplishments, including crossing the Hellespont. His deformity caused him shame throughout his life and sometimes engendered derision. He tried, with variable success, to conceal it, even from his doctors during his fatal illness in Greece.
ALMA Observations of NGC 6334S. I. Forming Massive Stars and Clusters in Subsonic and Transonic Filamentary Clouds

We present Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very Large Array (JVLA) observations of the massive infrared dark cloud NGC 6334S (also known as IRDC G350.56+0.44), located at the southwestern end of the NGC 6334 molecular cloud complex. The H13CO+ and NH2D lines covered by the ALMA observations at a ∼3″ angular resolution (∼0.02 pc) reveal that the spatially unresolved nonthermal motions are predominantly subsonic and transonic, a condition analogous to that found in low-mass star-forming molecular clouds. The observed supersonic nonthermal velocity dispersions in massive star-forming regions, often reported in the literature, might be significantly biased by poor spatial resolutions that broaden the observed line widths owing to unresolved motions within the telescope beam. Our 3 mm continuum image resolves 49 dense cores, whose masses range from 0.17 to 14 M
⊙. The majority of them are resolved with multiple velocity components. Our analyses of these gas velocity components find an anticorrelation between the gas mass and the virial parameter. This implies that the more massive structures tend to be more gravitationally unstable. Finally, we find that the external pressure in the NGC 6334S cloud is important in confining these dense structures and may play a role in the formation of dense cores and, subsequently, the embedded young stars.
Anomalous Bremsstrahlung and the Structure of Cosmic-Ray Electron–Positron Fluxes at the GeV–TeV Energy Range

−-source. and the distorted background

. We supposed that the difference between AMS-CALET and Fermi-LAT-DAMPE data originates from the energy loss of the fluxes due to the anomalous bremsstrahlung effect at a special window. The evolution of spectra under the anomalous bremsstrahlung effect satisfies an improved electromagnetic cascade equation. The above spectra are parameterized and they can be used for further physics studies. We suggest checking previous applications of the Bethe–Heitler formula when studying the propagation of high-energy electrons and photons.
Kinematics of Filaments in Cooling Flow Clusters and Heating by Mixing
Authors: Hillel Shlomi , Soker Noam
Published: June 2020

We compare a recent study of the kinematics of optical filaments in three cooling flow clusters of galaxies with previous numerical simulations of jet-inflated hot bubbles, and conclude that the velocity structure functions (VSFs) of the filaments better fit direct excitation by the jets than by turbulent cascade from the largest turbulent eddies. The observed VSFs of the optical filaments in the three clusters are steeper than that expected from a classical cascade in turbulent dissipation. Our three-dimensional hydrodynamical simulations show that as the jets inflate bubbles in the intracluster medium (ICM), they form vortexes in a large range of scales. These vortexes might drive the ICM turbulence with eddies of over more than an order of magnitude in size. A direct excitation of turbulence by the vortexes that the jets form and the slow turbulent dissipation imply that heating the ICM by mixing with hot bubbles is more efficient than heating by turbulent dissipation.
Gaussbock: Fast Parallel-iterative Cosmological Parameter Estimation with Bayesian Nonparametrics
Authors: Moews Ben , Zuntz Joe
Published: June 2020

We present and apply Gaussbock, a new embarrassingly parallel iterative algorithm for cosmological parameter estimation designed for an era of cheap parallel-computing resources. Gaussbock uses Bayesian nonparametrics and truncated importance sampling to accurately draw samples from posterior distributions with an orders-of-magnitude speed-up in wall time over alternative methods. Contemporary problems in this area often suffer from both increased computational costs due to high-dimensional parameter spaces and consequent excessive time requirements, as well as the need to fine-tune proposal distributions or sampling parameters. Gaussbock is designed specifically with these issues in mind. We explore and validate the performance and convergence of the algorithm on a fast approximation to the Dark Energy Survey Year 1 (DES Y1) posterior, finding reasonable scaling behavior with the number of parameters. We then test on the full DES Y1 posterior using large-scale supercomputing facilities and recover reasonable agreement with previous chains, although the algorithm can underestimate the tails of poorly constrained parameters. Additionally, we discuss and demonstrate how Gaussbock recovers complex posterior shapes very well at lower dimensions, but faces challenges to perform well on such distributions in higher dimensions. In addition, we provide the community with a user-friendly software tool for accelerated cosmological parameter estimation based on the methodology described in this paper.
New records and an updated checklist of snakes from Son La Province, Vietnam
Authors: Pham Anh , Ziegler Thomas , Nguyen Truong
Published: June 2020

Son La Province is located in north-western Vietnam and the province contains a large area of 440,000 hectares of natural forest. A wide range of elevations and the complexity of landforms have given this province a great diversity of natural habitats and a high level of biodiversity potential. However, the snake fauna of Son La province is still poorly studied. Previous studies documented 56 species of snakes from this province.

As a result of our field surveys in Phu Yen, Song Ma, Thuan Chau and Van Ho districts, we report five species of snakes for the first time from Son La Province, northern Vietnam, namely Boiga cyanea, B. guangxiensis, Lycodon meridionalis (Colubridae), Protobothrops cornutus and P. mucrosquamatus (Viperidae), with novel data about morphological characters. In addition, we provide an updated checklist of 61 snake species from Son La Province. The snake fauna of Son La Province also contains a number of species of conservation concern: 11 species listed in the Red Data Book of Vietnam (2007), four species listed in the IUCN Red List (2020) and four species listed in the Vietnam Governmental Decree No. 06 (2019).

Authors: Iturrieta-González Isabel , Gené Josepa , Wiederhold Nathan , García Dania
Published: June 2020

Curvulariais a Pleosporalean monophyletic genus with a great diversity of species, including relevant phytopathogenic, animal and human pathogenic fungi. However, their microscopic identification is difficult due to overlapping morphological features amongst species. In recent years, multi-locus sequence analysis using the ITS region of the rDNA and fragments of the genesgapdhandtef1 revealed numerous cryptic species, especially in isolates that commonly produced 3-septate conidia. Therefore, based on sequence analysis of the above-mentioned DNA barcodes recommended for species delineation inCurvularia, we propose three novel species,C. paraverruculosa,C. suttoniaeandC. vietnamensis, isolated from soil, human clinical specimens and plant material, respectively, collected in different countries. These new species are morphologically characterised and illustrated in the present study.Curvularia paraverruculosadiffers from its counterparts,C. americanaandC. verruculosa, mainly by its narrower conidia.Curvularia suttoniaeandC. vietnamensisare closely related toC. petersonii, but the former two have larger conidia.
A comparative study of English and Greek tough -movement constructions
Authors: Alexiadou Artemis , Anagnostopoulou Elena
Published: June 2020

Dans cet article, nous discutons des constructions à mouvement tough en grec, que nous comparons à leurs équivalents anglais. Nous soutenons que les données du grec plaident pour une analyse en termes de ‹génération de base› des constructions de mouvement tough . Nous proposons, en outre, une explication du fait que très peu de prédicats fonctionnent comme des prédicats tough dans cette langue. Enfin, nous abordons la question du changement diachronique qu’ont subi les constructions de mouvements tough en grec, ce qui a entraîné la présence obligatoire d’un clitique dans la proposition enchâssée.
Les adjectifs tough du français comme prédicats dispositionnels
Authors: Van de Velde Danièle
Published: June 2020

L’objectif de ce travail est de décrire le sens des tough -adjectifs (TA) dans les Tough -constructions (TC) de type [SN est Adj à Vinf ( pour y)] et les constructions impersonnelles de type [ Il est Adj ( à SN) de Vinf x], en montrant qu’il n’est pas exactement le même. Dans les constructions impersonnelles, l’adjectif a deux arguments (‹Vinf x› et ‹ à SN›) ; dans les TC, ce même adjectif constitue avec l’infinitif un unique prédicat complexe à un seul argument – le SN sujet de prédication –, le complément en pour n’étant qu’un adjoint. Cette démonstration se fonde sur une analyse des rôles respectifs de l’adjectif et de l’infinitif, dans le groupe adjectival, l’adjectif qualifiant le sujet et l’infinitif spécifiant eu égard à laquelle de ses ‹dimensions› le sujet mérite cette qualification. Ces propriétés du TA permettent de le considérer comme un prédicat typiquement ‹dispositionnel›.
