Ultra-hot Jupiters orbit very close to their host star and consequently receive strong irradiation, causing their atmospheric chemistry to be different from the common gas giants. Here, we have studied the atmosphere of one of these particular hot planets, MASCARA-2b/KELT-20b, using four transit observations with high resolution spectroscopy facilities. Three of these observations were performed with HARPS-N and one with CARMENES. Additionally, we simultaneously observed one of the transits with MuSCAT2 to monitor possible spots in the stellar surface. At high resolution, the transmission residuals show the effects of Rossiter-McLaughlin and centre-to-limb variations from the stellar lines profiles, which we have corrected to finally extract the transmission spectra of the planet. We clearly observe the absorption features of CaII, FeII, NaI, Hα, and Hβ in the atmosphere of MASCARA-2b, and indications of Hγ and MgI at low signal-to-noise ratio. In the case of NaI, the true absorption is difficult to disentangle from the strong telluric and interstellar contamination. The results obtained with CARMENES and HARPS-N are consistent, measuring an Hα absorption depth of 0.68 ± 0.05 and 0.59 ± 0.07%, and NaI absorption of 0.11 ± 0.04 and 0.09 ± 0.05% for a 0.75 Å passband, in the two instruments respectively. The Hα absorption corresponds to ~1.2 Rp, which implies an expanded atmosphere, as a result of the gas heating caused by the irradiation received from the host star. For Hβ and Hγ only HARPS-N covers this wavelength range, measuring an absorption depth of 0.28 ± 0.06 and 0.21 ± 0.07%, respectively. For CaII, only CARMENES covers this wavelength range measuring an absorption depth of 0.28 ± 0.05, 0.41 ± 0.05 and 0.27 ± 0.06% for CaII λ8498Å, λ8542Å and λ8662Å lines, respectively. Three additional absorption lines of FeII are observed in the transmission spectrum by HARPS-N (partially covered by CARMENES), measuring an average absorption depth of 0.08 ± 0.04% (0.75 Å passband). The results presented here are consistent with theoretical models of ultra-hot Jupiters atmospheres, suggesting the emergence of an ionised gas on the day-side of such planets. Calcium and iron, together with other elements, are expected to be singly ionised at these temperatures and be more numerous than its neutral state. The Calcium triplet lines are detected here for the first time in transmission in an exoplanet atmosphere.

AbstractCongenital disorders of autophagy are multisystem disorders with significant neurological involvement. Ectopic p-granules protein 5 (EPG5)-associated Vici syndrome is a prototypical congenital disorder of autophagy and presents with the cardinal features of agenesis of the corpus callosum, cataracts, cardiomyopathy, immunodeficiency, and oculocutaneous hypopigmentation. The majority of EPG5 variants leading to Vici syndrome are null alleles with only a few missense variants published to date. Here we report a 3.5-year-old male with compound heterozygous EPG5 variants [NM_020964.2: c.772G > T/c.5943–9_5943–5del]. His clinical presentation deviates notably from classic Vici syndrome with a lack of hypopigmentation, cataracts, immunodeficiency, cardiomyopathy, or failure to thrive. Neurological manifestations within the known disease spectrum include early-onset global developmental delay, hypotonia, and postnatal microcephaly. Seizures, hearing loss, or optic nerve atrophy are absent, however. Magnetic resonance imaging demonstrates a thin but fully formed corpus callosum. Based on the ameliorated and primarily neurological phenotype, we hypothesized that the functional impact of the EPG5 variants present would be milder with a higher amount of residual EPG5 expression. Analyses of EPG5 messenger ribonucleic acid (mRNA) in the patient and his parents were performed to examine expression level and splicing; mRNA from a healthy control and a patient with classic Vici syndrome was also included. Aberrant splicing due to the intronic mutation was detected, but no loss of expression. In contrast, we observed a 50% reduction in mRNA expression in classic Vici syndrome patient fibroblasts. These results support a model of disease severity, which correlates to the dosage of EPG5 expression.

Background and Objective CD45 is a receptor protein tyrosine phosphatase present on the surface of all hematopoietic cells except for erythrocytes and platelets. Proteomics studies, however, have demonstrated the presence of a CD45 c-terminal catalytic peptide in platelets. Therefore, we investigated the functional role of this truncated isoform of CD45 in platelets, which contains the c-terminal catalytic domain but lacks the extracellular region.
Methods and Results We used an antibody specific to the c-terminus of CD45 to confirm the presence of a truncated CD45 isoform in platelets. We also examined ex vivo and in vivo platelet function using CD45 knockout (KO) mice. Aggregation and secretion mediated by the glycoprotein VI (GPVI) receptor was impaired in CD45 KO platelets. Consequently, CD45 KO mice had impaired hemostasis indicated by increased tail bleeding times. Also, using a model of pulmonary embolism we showed that CD45 KO mice had defective in vivo thrombus formation. Next, we investigated whether or not the truncated isoform of CD45 had a role in GPVI signaling. The full-length isoform of CD45 is known to regulate Src family kinase (SFK) activation in lymphocytes. We find a similar role for the truncated isoform of CD45 in platelets. SFK activation was impaired downstream of the GPVI receptor in the CD45 KO murine platelets. Consequently, Syk, PLCγ2, and pleckstrin phosphorylations were also impaired in CD45 KO murine platelets.
Conclusion We conclude that the truncated CD45 isoform regulates GPVI-mediated signaling and platelet functional responses by regulating SFK activation.

Published: June 2019

Objectives This study aimed to describe a stress radiography to detect medial glenohumeral ligament rupture and to investigate the repeatability and reproducibility of this test.
Materials and Methods Six adult Beagle cadavers were used. Both shoulders of each dog were randomly assigned into two groups: a normal shoulder group (NS group) and an affected shoulder group (AS group) where the medial glenohumeral ligament was arthroscopically transected. Goniometry, image analysis and radiography (normal and stress views) were performed before and after arthroscopic procedures. An abduction angle was determined for each stress view and an evaluation of the repeatability and the reproducibility was performed.
Results Abduction angles were significantly larger in the AS group as measured by goniometer (p < 0.001), image analysis (p < 0.001) and radiographic stress view (p < 0.001) than in the NS group. The abduction angle difference varied from 12° to 29.3° (median difference of 19.4°) between NS and AS groups. There were good intra-observer and very good inter-observer agreements. A very good (r = 0.74; r = 0.72, respectively) significant (p < 0.001) positive correlation between goniometric and radiographic techniques and between image analysis and radiographic techniques was observed.
Clinical Significance Shoulder abduction angles measured with a stress radiograph-specific view provide objective data that may contribute to diagnosis of medial shoulder instability in dogs.

Published: June 2019

Introduction We analyzed perioperative risk factors for morbidity and mortality for the patients undergoing surgical intervention for vestibular schwannoma along with rates of cerebrospinal fluid (CSF) leaks that required surgery.Materials and Methods Patients undergoing surgery vestibular schwannoma were identified in the American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2016 using current procedural terminology (CPT) codes for posterior fossa surgical approaches and International Classification of Diseases 9th revision (ICD 9) and ICD 10 codes for peripheral nerve sheath tumor. Preoperative laboratories, comorbidities, and operative times were analyzed along with CSF leaks and unplanned returns to the operating room.Results Nine-hundred ninety-three patients fit the inclusion criteria. Average age was 51, 41% were male, and 58% were female. Mortality within 30 days of the operation was very low at 0.4%, complications were 7% with infection being the most common at 2.3%, and unplanned reoperations happened in 7.4% of the cases. Dependent functional status (odds ratio [OR]: 5.7, 95% confidence interval [CI]: 1.9–16.6, p = 0.001), preoperative anemia (OR: 2.4, 95% CI: 1.2–4.5, p = 0.009), and operative time over 8 hours (OR: 1.9, 95% CI: 1.1–3.4, p = 0.017) were the only significant predictors of perioperative complications. CSF leak postoperatively occurred in 37 patients (3.7%). Reoperation for CSF leak was necessary in 56.3% of the cases. Operative time over 8 hours was the only independent significant predictor of postoperative CSF leak (OR: 2.2, 95% CI: 1.1–4.3, p = 0.028).Conclusion Dependent functional status preoperatively, preoperative anemia, and duration of surgery over 8 hours are the greatest predictors of complications in the 30-day postoperative period.
Converting existing transmission corridors to HVDC is an overlooked option for increasing transmission capacity
Authors: Reed Liza , Morgan M. Granger , Vaishnav Parth , Erian Armanios Daniel 
Published: June 2019

Significance
A sustainable electricity grid will likely need to move large amounts of low-carbon bulk power as part of a strategy to reduce emissions. That will require expansion of transmission capacity, and changes in the topology of the system, even as the use of distributed generation increases. In many cases, maximizing the capacity of existing transmission corridors may best be done by conversion to high-voltage direct current (HVDC). While typically not included in planning tools, such conversion is surprisingly cost-effective, even over relatively short distances, and, in some cases, may be the only way to achieve dramatic increases in the capacity of existing corridors. Conversion may become even more attractive as new solid-state power electronics become available.

Published: June 2019

Abstract
Based on high throughput density functional theory calculations, we evaluated systematically the stability of 580 M2AX compounds. The thermodynamic, mechanical, and dynamical stability and the magnetic structure are calculated. We found 20 compounds fulfilling all three stability criteria, confirming Cr2AlC, Cr2GeC, Cr2GaC, Cr2GaN, and Mn2
GaC, which have been synthesized. The stability trends with respect to the M- and A-elements are discussed by analyzing the formation energies, indicating that Cr and Mn containing M2AX compounds are more stable than Fe, Co, or Ni containing compounds. Further insights on the stability are obtained by detailed analysis of the crystal orbital Hamilton population (COHP).
Magnetic field independent shape of the zero-energy landau levels in a disordered T3 model

Published: June 2019

Abstract
Using the Lanczos recursion method, we exactly determine the shape of the zero-energy Landau level (LL) in a disordered T
3 lattice under a strong magnetic field. We discover that the shape of the zero-energy LL depends on the distribution of disorder, but is independent of magnetic field strength. Our analytical study attributes this intriguing behavior to the macroscopic and magnetic field independent degeneracy owing to the existence of the flat band. Moreover, our simulations unravel that the density of states obeys an unconventional scaling law, leading to the fact that the relation between the magnetoconductivity and the carrier density is independent of the disorder strength.

Published: June 2019

Abstract
The problem of utilization of production and consumption wastes is relevant for many countries and regions. Most sharply it is shown in regions with high concentration of the population and production. Such region in the south of Russia is the Rostov region. Formation in the territory of the Rostov region of large volumes of industrial and consumption waste is bound to the production specialization of economy of the region, intensive agriculture, high concentration of infrastructure facilities, dense population, prevalence of the cities. In the system of collecting and storage of a wastage in the territory of the region there are considerable shortcomings – the large number of dumps is used, there is no recycling of a wastage. These problems cause the necessity of searching of the new efficient scheme of salvage. As a way of a solution of the problem of a salvage in the Rostov region creation of 8 intermunicipal ecological waste processing complexes is considered. Parts of each complex will be solid waste landfills, the plants on sorting of garbage, the station on an overload of garbage and other infrastructure facilities on processings of a wastage. As a result, this project will allow to capture garbage removal all settlements of the Rostov region, to adjust processing of a wastage in secondary raw materials, to perform deep disinfecting of garbage and burial of its safe parts that will be significantly improved ecological by a situation in the region.

Authors: Kopylov P , Nazarov V P , Fedotkin D V 
Published: June 2019

Abstract
It is shown that for determination of tanks stability to explosion of gas-air mixtures it is important to calculate explosion pressure in dynamics (at filling or emptying of the tank) depending on level of filling. A method for determination of explosion pressure in the tanks is proposed, taking into account the dependency of the volume of hazardous area from time. It is shown that the formation of the zone of explosive concentrations is divided into three types depending on the ratio of saturated vapor concentration to the lower and upper flammability limits, and for RVS-5000 tanks the type II is characteristic. The results of calculations of explosion pressure from the time of evaporation taking into account the volume of explosion-hazardous area for a tank of 5000 m3 are presented.

Authors: Serzhan S L , Trufanova I S , Malevannyi D V 
Published: June 2019

Abstract
Deep sea solid mineral resources (SMR) of the World Ocean, such as ferromanganese nodules (FMN), cobalt-manganese crusts (CMC) and the depth polymetallic sulphides (DPS) should become an alternative source of mineral resources in the near future. Reliable and productive complexes are necessary for the implementation of deep-sea mining on an industrial scale, which will be able to develop deposit with a minimum ecosystem load. So, the main problems in technological solutions are the collection or separation of SMR at the bottom and lifting them to the surface. As a technical solution, it is proposed to use a special construction draghead device for FMN and CMC collecting and separating from the bottom. The distinctive feature of the device is a vertical axis of rotation of the drive engine and the working body, which can be represented by a faceplate or a crown, the working element with the engine are concentrically inscribed in the casing with the catcher, which enclose the loosening zone, protecting surrounding water area from the turbulent mud and separated fractions. Nodules and crusts lifting using the draghead is carried out in the form of slurry through a pipeline.

Published: June 2019

Abstract
High concentration of mining enterprises in cryolithozone in Yakutia can become the reason of economic loss because of climate warming anomalies. The paper deals with the investigation of the features of cryolithosystems reaction to climate change and search for a certain rhythmic ordering of climatic fluctuations and response to it of space-time shifts in cryolithosystems. According to the results of engineering and geological surveys carried out by the authors in 2001-2017, numerical modeling of series of average annual temperatures of the hydrometeorological station Yakutsk (Central Yakutia) was conducted by means of Fourier Analysis, wavelet Analysis and series autocorrelation analysis. Temperature fluctuations associated with 11, 22, 36. 48 and 72-year solar-conditioned cycles were detected. The wavelet analysis also showed the presence of less short-term periodic oscillations. A large cyclic temperature wave with a period of about 75 years is revealed. A forecast of the development of warming change in Yakutia for the coming decades is made. After a short decline in the rate of warming, intensification of its dynamics in the late twenties and during the thirties of this century, as well as in the second half of the current century cycle is predicted. Inertial processes in the permafrost zone will lead to its greatest destruction in 20-30 years after the accentuation of increased warming.

Authors: Tsuprik V G , Zanegin V G , Kim L V 
Published: June 2019

Abstract
Determination of the force effect of ice formations on the marine structure is based on a model of interaction with the edge of the ice field. The development of a model of ice failure accounting for the results of studies of the failure mechanism of the ice field edge with the surface of the vertical shape structure is presented. The processes of cracking and shear of different nature with the formation of large and small fragments are described with mathematical model. A criterion of the limit value of the accumulated potential energy of elastic compression of the ice volume before structure is proposed as specific energy of mechanical failure of sea ice. The values of this criterion, which takes into account all types of ice failure, are obtained experimentally by testing large samples of ice on dynamic crushing.

Published: June 2019

Abstract
The paper deals with the thermal remote sensing data application in verification of Voronezh urban heat island model. We computed surface temperature layer and temperature variation layer for the warm season of 2015 on the basis of Landsat 8 TIRS scenes set. The values from those layers and the urban heat island layer at 234 ground control areas were compared. It validated the urban heat island model for built-up areas and showed the thermal differences for water and forests surfaces. To convert the real surface temperatures to urban heat island scores a regression model was computed. The study reveals that the thermal remote sensing data and the urban heat island model are complimenting each other in case of microclimatic studies in Voronezh.

Published: June 2019

Abstract
The article offers a brief overview of geochemical methods for petroleum prospecting and testing results of the exploration method based on hydrocarbon gas content in soil. For interpretation of the materials a new criterion developed by the authors was used— the naphtide coefficient. As a result of the testing high efficiency of the method is confirmed and it lead to localizing prospects within the Ukhta-Izhma region. Use of this method can contribute to the expansion of the hydrocarbon resource base in the region and demonstrate petroleum potential of unconventional structures of the Timan ridge. Analog to this, structures of the Rocky Mountains thrust belt and other oil and gas-bearing regions in the world, might demonstrate unexpectedly high hydrocarbon potential.
