Conceptualisations of Territorial Cohesion in Central European border regions

ABSTRACT Despite decades of spending, Cohesion Policy appears unable to fully address growing national disparities and increasing ‘roll-out’ nationalism. In the present study we discuss regional effects of ‘fuzzy’ policy concepts, such as EU’s policy for Territorial Cohesion, in Central European borderlands from a stakeholder perspective. Identifying how key policy documents have framed the discussion of Territorial Cohesion, we furthermore demonstrate the differing ways regional stakeholders have interpreted this vision. By showing how multiple translations have produced dynamics that create a circular process, we conclude that this process leads towards non-comparable outcomes, increased misunderstanding, while fuelling EU scepticism.
Genomic profiling of cell lines reveals hidden research bias and caveats

Cancer cell lines are extremely valuable tools for carcinoma research. Biodiversity of cell lines and continuous random mutation in cell lines during passage, however, might result in phenotypic inconsistency and lead to biased experimental conclusions. Using statistics based on known and inferred protein interaction networks, as well as public research literature database, our study shows that essential driver genotypes of cell lines might have hidden impact on research results. Furthermore, by comprehensive genomic profiling of 8 most common used urothelial cell lines and comparing them to previous publications, we found that regardless of similar short tandem repeat (STR) profile, driver gene loss in cell lines could happen by random mutation. Our results suggest that clinical research using urothelial carcinoma cell lines might be influenced by cell line genotypes which could only be determined by next-generation sequencing. Meanwhile, this study indicates that the conditionally reprogrammed cells (CRCs), which closely resemble original tumor tissue, might represent a better alternative for in vitro research, which may be better used for personalized medicine.
Optimization of multilayer anti-reflection coatings for efficient light management of PEDOT:PSS/c-Si heterojunction solar cells

In this paper, we present a theoretical model for the optimization of multilayer anti-reflection coatings for PEDOT:PSS/c-Si heterojunction solar cell based on optical interference transfer-matrix theory. A comprehensive idea of designing multilayer anti-reflection coatings (ARCs) on the solar cell and minimization of the overall reflectance is provided in this work. Optical reflectance values for various single, double and three layer anti-reflection coatings on PEDOT:PSS deposited c-Si substrate have been deduced using a MATLAB program and compared with that of the measured value. The reflectance value is calculated to be lower than 4% in the visible wavelength spectra for ARC by alternately using high and low refractive index materials. This low value of reflectance suggests that the anti-reflection coating layers proposed in this study can be employed as the standard ARC materials for optical coatings of the PEDOT:PSS/c-Si heterojunction solar cells.
A Formal Technique for Text Summarization from Web Pages by using Latent Semantic Analysis

Web is the more attractive media for information consulting of, practically, whatever theme; humanity considers the Web, in the facts, the standard source of information. However as content grows, effort for discriminating and ﬁltering increases too. Orthogonally, users employ each time smaller devices with reduced screens for web reviewing. Both considerations suggest the neediness of software tools for information acquiring and reduction, i.e., text summarization. There are several methods for text summarization, however, majority of them are based on techniques who considere plain documents in contrast with tree like structures of web pages, other are settled on the existence of keywords ignoring relations among words. In this work we present a formal method for the preparation of text summaries based on latent semantic analysis (LSA), which exploits the implicit relationships between the words that appear in a common context. In this way, text summaries are enriched with a certain semantic ﬂavor incorporated by LSA. Furthermore we prepare the text summary induced by the query of an user and retrieving text excerpts more semantically similar to user’s interest. Additionally we deﬁne a formula called semantic similarity which encapsulates the properties of LSA and determines the best text web page node for producing summaries.
The Control Technique of AGC under Regional Grid Security Constraint and Dispatching Principles of Openness, Impartiality and Fairness

Renewable energy generation (REG), including wind farms and solar plants, are continuously installed in power systems with a relatively high speed. Due to large portion of installation and intermittent characteristic, fully absorbing REG has become a troublesome problem when under certain regional grid security constraints and dispatching principles for grid dispatchers. Based on the strategy of auto generating control and the heuristic optimization method of differential evolution (DE), a novel AGC implemented with the algorithm of the variant of DE (orthogonal learning differential evolution (OLDE)) is designed to solve the problem. In this paper, a 39-node New-England system with renewable energy plants paralleled is adopted to verify the performance. The experimental results with power increasing and decreasing cases both display that the AGC can meet the demand. Keywords—renewable energy generation; AGC; grid dispatching; orthogonal learning differential evolution
The Effect of Residential Segregation on Formal and Informal Employment of Roma in Serbia

ABSTRACT This paper aims to examine whether the degree of residential segregation affects formal and informal employment of the Roma ethnic minority in Serbia. I exploit the within district variation in the percentage of Roma to identify the effect of residential segregation on labor market outcomes. The results show that Roma in more segregated census tracts are more likely to hold an informal job than Roma in less segregated census tracts. There is suggestive evidence that the positive effect of segregation is driven by the information spillovers between Roma. I do not find an effect of residential segregation on employment in the formal sector.
Secondary Control for Storage Power Converters in Isolated Nanogrids to Allow Peer-to-Peer Power Sharing

It is usual in literature that power sharing among grid-forming sources of an isolated microgrid obeys their energy rating, instead of economic agreements between stakeholders, and circulating energy among them is usually avoided. However, these energy interchanges make strong sense and classical power sharing methods must be reformulated in the context of prosumer-based microgrids. This paper proposes a secondary control method for a prosumer-based low-voltage nanogrid that allows for energy interchange between prosumers, where storage systems, together with PV generators, are the controllable grid-forming sources. A power flow technique adapted to islanded microgrids is used for secondary control algorithm and the whole hierarchical control strategy for the prosumer converter is simulated and validated. This hierarchical control consists of three stages: tertiary control plans the energy interchange among prosumers, secondary obtains different voltage and power setpoints for each of the grid-forming sources, and, finally, primary control guarantees stable voltage and frequency values within the nanogrid with droop rules. Inner control loops for the power converter are also defined to track setpoints and assure stable performance. Simulation tests are carried out, which prove the stability of the proposed methods and the accuracy of the setpoint tracking.
Multiscale MHD‐Kinetic PIC Study of Energy Fluxes Caused by Reconnection

We present an analysis of the energy partitioning in the magnetotail during a substorm at 03:58:00 UT on 7 February 2009. The analysis employs a multiscale approach where we use a state from a global magnetohydrodynamics (MHD) model to spawn a kinetic particle‐in‐cell (PIC) simulation of a large portion of the tail. We directly investigate the energy fluxes resulting from magnetic reconnection. The kinetic run provides information on the additional processes absent in the MHD description. The ion bulk energy and enthalpy fluxes carry the greatest energy, but the Poynting flux and electron enthalpy flux also carry a significant portion. The other fluxes (e.g., heat flux) are relatively small but are especially important because they allow us to identify the extra processes present only in the kinetic description. The energy fluxes present in the MHD approximation (Poynting flux, enthalpy flux, and bulk energy flux) are quantitatively accurate, and the kinetic correction does not greatly alter the MHD picture. However, there are two unique effects resulting from the kinetic physics. First, the formation of a rarefaction of the plasma flow into the reconnection site leads to a progressive decline in time of the particle energy fluxes with respect to the Poynting flux. Second, we observe that the instabilities developing in the kinetic reconnection outflows form structures absent from the MHD description. These structures reveal themselves as fluctuations within the energy fluxes. Especially notable are regions of inverted heat flux, where the heat flux is in the opposite direction to the total energy and mass flow.
The aging of heroes: Posttraumatic stress, resilience and growth among aging decorated veterans

ABSTRACT Despite increasing interest in the mental health of aging veterans, the pathogenic and salutogenic ramifications of war have not been investigated among aging veterans who received decorations of valor. Filling this gap, 73 Israeli decorated veterans (DVs) and 73 non-decorated veterans (n-DVs) (M age = 68.5) were assessed for posttraumatic stress symptoms (PTSS), depression and anxiety 18 and 45 years after the war, and for posttraumatic growth (PTG) 45 years after the war. Analyses revealed deteriorating posttraumatic avoidance among n-DVs but not among DVs, and significantly lower rates of anxiety and depression and higher rates of PTG among the DVs. These findings suggest that factors related to being a DV may foster resilience to posttraumatic sequelae and are potentially conducive to PTG in later life. Though the study precludes making causal inferences, it serves as a springboard for future investigations into positive mechanisms underlying DVs’ relative resilience and growth in later life.
Pancreatic Tuberculosis Abscess Successfully Treated With Serial Endoscopic Ultrasound-Guided Aspirations

A 28-year-old woman suffered from abdominal pain for 3 weeks before admission. The patient also had weight loss and a decrease in appetite. From the physical examination, we found abdominal tenderness in the right upper quadrant. The result of magnetic resonance imaging was a suspected pancreatic cyst. Endoscopic ultrasound (EUS) showed a hypoechoic lesion with a definite border in the head of the pancreas with lymph node enlargement (Figure 1). We performed fine-needle aspiration of the lesion which oozed pus (Figure 2). The fluid was sent for cytology examination and tuberculosis polymerase chain reaction (PCR). The cytology result showed giant cell granuloma, and the tuberculosis PCR was positive (Figure 3). We performed aspiration of the abscess 3 times every 2months until there was no pus aspirated and started administration of antituberculosis drugs for 9months. EUS evaluation was performed every 2 months. After treatment with antituberculosis medication, the patient’s abdominal pain was reduced, and she gained weight. EUS showed a decrease in size of the abscess and lymph nodes. The abscess resolved after 9 months (Figure 4).
A Technological and Typological Analysis of Lithic Material from Skovmosen I, Denmark

During road construction work, material attributed to the Final Palaeolithic was discovered at Skovmosen I, near Kongens Lyngby on Zealand, eastern Denmark. Although it is regularly mentioned in reviews of the southern Scandinavian Final Palaeolithic, the Skovmosen I assemblage has hitherto remained poorly described. We here review the site’s discovery history and its context. Aided by a three-dimensional digital recording protocol, this article details the assemblage composition and its technology. The assemblage is comprised of tanged points, scrapers and burins, alongside blades and cores as primary reduction products. Although evidently disturbed by the road construction that led to the site’s discovery, the material likely reflects the remains of a small Final Palaeolithic locale, where diverse activities were carried out.
Obesity Negatively Affects the Biological Functions of Mesenchymal Stromal Cells Derived from Bone Marrow, Subcutaneous and Visceral Fat of Young Mice

White adipose tissue (WAT) is distributed in several depots that have distinct metabolic and inflammatory functions. In our body there are subcutaneous (sWAT), visceral (vWAT) and bone marrow fat depots (BFAT). Obesity affects size, function and inflammatory state of WATs. This process can alter the stem cell niches present in these tissues and affect the functions of stem cells residing within. In particular, obesity may affect the activity of mesenchymal stromal cells (MSCs) present in WAT. MSCs are an heterogenous population containing stromal cells, progenitor cells, fibroblasts and stem cells that are able to differentiate in adipocytes, chondrocytes, osteocytes and other mesodermal derivatives. We performed a comparison of the effects of obesity on MSCs obtained from sWAT, vWAT and BFAT. Our study evidenced that obesity affected mainly the biological functions of MSCs obtained from bone marrow and vWAT with a decrease in proliferation rate, reduced percentage of cells in S phase and trigger of senescence. The onset of senescence was confirmed by expression of genes belonging to RB and P53 pathways. Our study evidenced that negative consequences of obesity on body physiology may be related also to impairment in the functions of stromal compartment present in the several adipose tissues. This finding provides new insights on the targets that should be considered for an effective treatment of obesity-related diseases.

Métodos cronobiológicos en las encuestas alimentarias: criterios de aplicación e interpretación de resultados

To evaluate the circadian system status of the subject may be of special interest in nutrition. Particularly for those studies related to the assessment of diseases related to malnutrition, as it is the case of most of the degenerative diseases such as obesity, cancer, or cardiovascular diseases. For this purpose, one of the approaches consists to measure a) the external synchronizers of the internal clock, such as light intensity, and changes from fasting to eating and from resting to activity. Indeed, “chronodisruptors” have been defined as “exogenous and endogenous exposures or effectors which are chronobiologically active and can thus disrupt the timing and order. Another approach to assess the circadian system health is to measure the b) outputs of the internal clock (circadian marker rhythms). Among such outputs, the rhythm of body temperature, motor activity, melatonin, cortisol and clock gene expression are the most commonly used. From the genetic perspective, we are now able to measure failures in the internal clock, in order to assess c) the genetics of the molecular clock. Indeed, new nutrigenetics techniques are giving us the opportunity to measure the association between different genetic variants of our clock genes and several illnesses such as obesity, cardiovascular diseases, diabetes or cancer. In addition to these techniques, selfreported questionnaires based in the morning-evening preferences have been developed as complementary procedures to assess human chronotypes.
Seasonal and longitudinal variation in fish assemblage structure along an unregulated stretch of the Middle Uruguay River

ABSTRACT Diversity patterns and their causes remain important questions, especially for ecosystems that preserve natural conditions. This is the case of fish diversity in large Neotropical rivers. In this context, we investigated fish diversity patterns along an extensive unregulated river section (ca. 450 km) in the Middle Uruguay River Basin. Sampling was conducted seasonally between May 2017 and March 2018, at six sites (patches) with contrasting environmental conditions. We collected 3,008 individuals belonging to 90 species. Nine were migratory, which summed relevant biomass in local assemblages (20 to 60%). We observed spatial variation in assemblage structure, but weak seasonal effects. Overall, biomass was similar among sites, but richness tended to increase downstream. Migratory fishes showed opposed trends, with higher richness and biomass upstream, particularly catfishes (Siluriformes). Ordination analyses separated sites in three groups based on variations in composition and abundance, and revealed associations between these groups and specific hydro-geomorphic conditions (i.e., flow, depth, channel width and the presence of riparian vegetation). Our study revealed that fish diversity distributes heterogeneously along the main channel, where hydro-geomorphic patches select for distinct assemblages along riverine gradients.
Structure, morphology and luminescence properties of sol-gel method synthesized pure and Ag-doped ZnO nanoparticles

Highly Crystalline pure and Ag-doped ZnO nanoparticles were prepared using the inexpensive sol-gel synthesis method with the stimulation of transition metal ion surfactant. The prepared pure and Ag-doped (Silver doped) ZnO nanoparticles were characterised by various sophisticated techniques like x-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Dynamic Light scattering (DLS), Fourier Transform Infrared Spectroscopy (FTIR), UV–visible absorption, Photoluminescence (PL) and Zeta potential. The result indicates that the average grain size of the prepared nanoparticles was found to be a minuscule 24 nm with a commendable bandgap of 3.21 eV and 1.73 eV respectively. The hexagonal wurzite structures of pure and Ag-doped ZnO at room temperature confirmed the luminescence characteristics of the nanoparticles.
Unearthing the buried Palu–Koro Fault and the pattern of damage caused by the 2018 Sulawesi Earthquake using HVSR inversion

Abstract A systematic pattern of destruction was observed caused by the Mw 7.5 Central Sulawesi Earthquake. In brief, the quake ruptured 180 km of Palu–Koro Fault and led to massive destruction of residential buildings in Palu city, Donggala and Sigi Regencies. In Palu city, the damage was concentrated only in Balaroa and Petobo neighbourhoods where at least 930 and 1255 houses, respectively, collapsed. Microtremor time series recorded prior to the earthquake were used to analyse the subsurface structure of Balaroa and surroundings. Surprisingly, inversion of horizontal-to-vertical spectral ratio curves was able to locate the subsurface fault crossing the Balaroa and its dipping direction. Furthermore, the velocity profile deduced from this inversion points out the importance of local geology in the massive destruction in Balaroa. The existence of a subsurface pond led to an extremely water-saturated sandy soil underneath Balaroa. A combination of high level of water saturation and high peak ground acceleration (0.5–0.7 g) was strongly suspected to be the cause of the mega-liquefaction. The high degree of ground motion (>1.54 g) of spectral acceleration 0.2 s resulted in severe damage in elevated areas in Donggala, while in the Palu Basin, ground motion as high as 1.30g of spectral acceleration 0.5 s led to the destruction of four-storey or higher buildings.
The virus integrations in gut microbes associated with dysbiosis of microbial community in tumorigenesis of colorectal carcinoma

Patients with colorectal cancer (CRC) have a different gut microbial and viral communities from healthy individuals. But little is known about the ways and functions of interaction of virus-bacteria, let alone its correlation with the aetiology of CRC. In this study we aimed to identify the association between the genetic integration of virusbacteria and the expansion of some microbial population during tumorigenesis of human colorectum. Using a gut metagenomics sequencing data of healthy controls, advanced adenoma and carcinoma patients, to our knowledge, we demonstrate for the first time that the viral genetic integrations in gut microbes tend to occur in CRC patients and are potentially associated with the carcinogenesis. We found that almost all of the genetic integrations were happened between bacteriophages and bacteria, which could be influenced by the abundance of the phage communities. Importantly, the integrations of phage-carried positive effective genes offered selective advantages to the commensal and potential pathogenic bacteria, as a result, potentially led to a microbial dysbiosis along with the increasing bacterial diversity in carcinoma patients. Consequently, our work opens a new way to understand the carcinogenicity in complex intestinal ecosystems.
Queering Menstruation: Trans and Non‐Binary Identity and Body Politics

Menstruation has been historically known as a function of the female body that affects women. Trans and non-binary people face this biological function as a potential social signal of gender/sex identity. This research involves virtual ethnographic content analysis of menstruation discourse written by or informed by trans and non-binary people in addition to 19 interviews with trans and non-binary participants. The research yields analysis within three gendered/sexed social spheres that trans and non-binary bodies contest: (1) the gendering of menstrual products; (2) men ’ s restrooms; and (3) health care. The ﬁ ndings depict the variety of strategies trans and non-binary people employ when navigating and interpreting menstruation in relationship to their gender/sex identities.
Eclampsia: a retrospective study in a tertiary care centre

Eclampsia remains one of the major causes of maternal mortality and morbidity in developing countries. In developing countries, case fatality ratio is upto 14% with eclampsia in relation to 1.8% in developed countries. In developed countries, incidence of eclampsia is much lower because of aggressive screening and management of preeclampsia. Majority of women who suffered eclampsia associated death had concurrent Hellp syndrome. Eclampsia is associated with increased rates of maternal complications like abruption placenta, pulmonary edema, Hellp syndrome and acute renal failure Preeclampsia is treatable and eclampsia is preventable. Majority of adverse outcomes can be avoided with proper prediction, timely diagnosis and early management.
