The refugee entrepreneurship process from/in emerging economies

2021

The paper examines several refugee experiences in Mexico and presents their reasons for leaving their home countries. A gap in research is identifying the entrepreneurial process experienced by refugee entrepreneurs. We use the case study of 10 Latin American refugees in Mexico to propose a conceptual framework that describes the entrepreneurial process of refugee entrepreneurs. We have found that this process begins with the abandonment of the country of origin, followed by the traumatic experiences that caused flight and the difficulties they face in the pilgrimage to the host country. These events help shape the entrepreneurial intention of the refugees.

Tooth tales told by dental diet proxies: An alpine community of sympatric ruminants as a model to decipher the ecology of fossil fauna

2021

Abstract Paleobiologists tend to use dietary information as an ecological indicator because diet is a fundamental link between an organism and its environment. However, the ecological information from fossilized hard tissues is often difficult to interpret, because links between environment, diet, and hard tissue biology are insufficiently studied in modern communities. To address this dilemma, we investigated dietary proxies commonly used by paleobiologists in a 4-ruminant community from the French Alps. Dental microwear texture analyses are applied to 82 specimens of roe deer, red deer, chamois, and mouflons. Intra-tooth serial enamel stable carbon and oxygen isotope analyses of the struc…

Electron beam studies of light collection in a scintillating counter with embedded fibers

2021

The light collection of several fiber configurations embedded in a box-shaped plastic scintillating counter was studied by scanning with minimum ionizing electrons. The light was read out by silicon photomultipliers at both ends. The light yield produced by the 855-MeV beam of the Mainz Microtron showed a strong dependence on the transverse distance from the beam position to the fibers. The observations were modeled by attributing the collection of indirect light inside of the counter and of direct light reaching a fiber to the total light yield. The light collection with fibers was compared to that of a scintillating counter without fibers. These studies were carried out within the develop…

Strain Release Chemistry of Photogenerated Small‐Ring Intermediates

2021

Abstract Photochemical processes, such as isomerizations and cycloadditions, have proven to be very useful in the construction of highly strained molecular frameworks. Photoinduced ring strain enables subsequent exergonic reactions which do not require the input of additional chemical energy and provides a variety of attractive synthetic options leading to complex structures. This review covers the progress achieved in the application of sequences combining excitation by ultraviolet light to form strained intermediates, which are further transformed to lower energy products in strain‐release reactions. As ring strain is considerable in small ring systems, photogenerated three‐ and four‐memb…

Pomegranate Cultivation in Mediterranean Climate: Plant Adaptation and Fruit Quality of ‘Mollar de Elche’ and ‘Wonderful’ Cultivars

2021

Two pomegranate cultivars, Mollar de Elche, native to Spain, and Wonderful, the most widely cultivated pomegranate variety in the world, were studied in a commercial orchard in Sicily, and their phenological behavior was compared. During the development of the fruit, their dimensional growth was monitored, and after harvest, physicochemical and sensory analyses were carried out to highlight the differences between fruit of the two cultivars. Results showed that Mollar de Elche fruit require less time from flowering to fruit maturity, resulting in an earlier harvest, which was due also to a higher relative growth rate of the fruit&rsquo

Factors Associated with Decisions for Initial Dosing, Up-Titration of Propiverine and Treatment Outcomes in Overactive Bladder Syndrome Patients in a…

2021

Two doses of propiverine ER (30 and 45 mg/d) are available for the treatment of overactive bladder (OAB) syndrome. We have explored factors associated with the initial dosing choice (allocation bias), the decision to adapt dosing (escalation bias) and how dosing relative to other factors affects treatment outcomes. Data from two non-interventional studies of 1335 and 745 OAB patients, respectively, receiving treatment with propiverine, were analyzed post-hoc. Multivariate analysis was applied to identify factors associated with dosing decisions and treatment outcomes. Several parameters were associated with dose choice, escalation to higher dose or treatment outcomes, but only few exhibited…

Suso de Toro, écrivain galicien, ou la littérature au service de la langue

2021

Suso de Toro (Saint Jacques de Compostelle, 1956) fête cette année ses vingt ans de carrière depuis la publication en 1983 de son premier roman intitulé Caixón Desastre. Certains critiques littéraires n’hésitent pas à qualifier ce texte de “fondamental et fondateur” (González-Millán, 1996 : 280) dans le sens où il a bouleversé, autant sur la forme que sur le fond, le panorama littéraire galicien. En 1986, de Toro publie Polaroid, son second roman qui, avec le temps, sera salué par le Dicciona...

Zero- to Ultralow-Field NMR Spectroscopy of Small Biomolecules.

2021

Nuclear magnetic resonance (NMR) spectroscopy is a well-established analytical technique used to study chemicals and their transformations. However, high-field NMR spectroscopy necessitates advanced infrastructure, and even cryogen-free benchtop NMR spectrometers cannot be readily assembled from commercially available components. We demonstrate construction of a portable zero-field NMR spectrometer employing a commercially available magnetometer and investigate its applications in analytical chemistry. In particular, J-spectra of small representative biomolecules [13C]-formic acid, [1-13C]-glycine, [2,3-13C]-fumarate, and [1-13C]-d-glucose were acquired, and an approach relying on the prese…

De la Marea Adriatică în Dacia, aventura monedelor tezaurului de la Apoș (lotul III)

2021

In the collection of Valea Hârtibaciului Museum of Agnita is kept a group of coins issued by Dyrrhachium and discovered at Apoș. This lot contains 10 coins which can be part of the Apoș hoard, from which two lots, preserved in the Brukenthal National Museum’s numismatic collection, were published. Taking in account all those groups, we can establish that, at least until now, we know 54 coins of this hoard. Like many others monetary deposits with Dyrrhachian coins found in Dacia, this one it is dominated by the coins of group V. It is very possible to have a hiding horizon in the southern Transylvania dated no long after the middle of the 1st century BC, probably created by the harsh politic…

Numerical Magnitude Affects Accuracy but Not Precision of Temporal Judgments

2021

A Theory of Magnitude (ATOM) suggests that space, time, and quantities are processed through a generalized magnitude system. ATOM posits that task-irrelevant magnitudes interfere with the processing of task-relevant magnitudes as all the magnitudes are processed by a common system. Many behavioral and neuroimaging studies have found support in favor of a common magnitude processing system. However, it is largely unknown whether such cross-domain monotonic mapping arises from a change in the accuracy of the magnitude judgments or results from changes in precision of the processing of magnitude. Therefore, in the present study, we examined whether large numerical magnitude affects temporal ac…

Female sexual signaling in a capital breeder, the European glow-worm Lampyris noctiluca

2021

AbstractTheory predicts that because costs constrain female sexual signaling, females are expected to have a low signaling effort that is increased with passing time until mating is secured. This pattern of signaling is expected to result from females balancing the costs associated with a higher than optimal signaling effort and those costs associated with a low signaling effort that increase the likelihood of delayed mating. We tested whether this prediction applies in the common glow-worm Lampyris noctiluca (Coleoptera, Lampyridae), a capital breeding species in which females glow at night to attract males. Contrary to predictions, we found that the duration of female sexual signaling sig…

Cargo transport through the nuclear pore complex at a glance.

2021

ABSTRACT Bidirectional transport of macromolecules across the nuclear envelope is a hallmark of eukaryotic cells, in which the genetic material is compartmentalized inside the nucleus. The nuclear pore complex (NPC) is the major gateway to the nucleus and it regulates nucleocytoplasmic transport, which is key to processes including transcriptional regulation and cell cycle control. Accordingly, components of the nuclear transport machinery are often found to be dysregulated or hijacked in diseases. In this Cell Science at a Glance article and accompanying poster, we provide an overview of our current understanding of cargo transport through the NPC, from the basic transport signals and mach…

Model-assisted ultrasonic calibration using intentionally embedded defects for in-process weld inspection

2021

Abstract Automated in-process Non-Destructive Testing (NDT) systems are rapidly gaining traction within the manufacturing industry as they reduce manufacturing time and costs. When considering calibration and verification of such systems, creating defects of known geometry and nature during the deposition of a weld can: (I) help examine the capability of the automated system to detect and characterise defects, (II) be used to form a database of signals associated with different defect types to train intelligent defect classification algorithms, and (III) act as a basis for in-process gain calibration during weld inspection at high temperatures, where the ultrasound beam can be skewed as a r…

Characterization of the land snail Ganula lanuginosa (Boissy, 1835) (Mollusca: Hygromiidae): new invader of the Iberian Peninsula.

2021

Recently, a well-established population of the hygromiid Ganula lanuginosa has been discovered in the Iberian Peninsula, specifically in Xàtiva (Province of Valencia, Spain), corresponding to the first record for the Iberian Peninsula and the Continental Europe. It is a land snail native to North Africa and also known from the European Mediterranean islands, namely the Balearic Islands (Spain), Sardinia (Italy) and Corsica (France). Morpho-anatomical studies of the shell and the reproductive system have been carried out, and these features have been compared with those of the most similar hygromiids, which has allowed us to correctly identify them. In addition, parasitological and ec…

Două tehnici, un singur iconar: Savu Moga

2021

This article brings to attention the work of Savu Moga, a famous icon painter who lived and worked in the 19th century in Transylvania. His artistic talent was native and his greatest skills were revealed by his icons painted on glass, but he also painted icons on wood, a less known fact. Brâncoveanu Monastery from Sâmbăta de Sus, Brașov county, owns 10 icons painted on wood, which are in the process of restoration and research. The technique of painting on wood brings to Moga certain difficulties, which he tried to solve. Although the supports and techniques are different and the order of the stages is reversed, the style of work is very much alike. The colours, the way he writes, the vege…

Deep Learning-Based Methods for Prostate Segmentation in Magnetic Resonance Imaging

2021

Magnetic Resonance Imaging-based prostate segmentation is an essential task for adaptive radiotherapy and for radiomics studies whose purpose is to identify associations between imaging features and patient outcomes. Because manual delineation is a time-consuming task, we present three deep-learning (DL) approaches, namely UNet, efficient neural network (ENet), and efficient residual factorized convNet (ERFNet), whose aim is to tackle the fully-automated, real-time, and 3D delineation process of the prostate gland on T2-weighted MRI. While UNet is used in many biomedical image delineation applications, ENet and ERFNet are mainly applied in self-driving cars to compensate for limited hardwar…

Synthesis of a rod-based porous coordination polymer from a nucleotide as a sequential chiral inductor

2021

We report the two-step synthesis of a novel chiral rod-based porous coordination polymer (PCP). The chemical approach consists of the use of a previously prepared bis(ethylenediamine) copper monomer [Cu(en)]2(NO3)2 [where en = ethylenediamine] reacting with the cytidine 5′-monophosphate (CMP) nucleotide. The bis(ethylenediamine) copper compound—stabilized by axial coordination of nitrate counter-anions—reacts in the presence of sodium salt of CMP to yield right-handed copper(II) chains of P helicity with formula [Cu2(en)2(CMP)2]·5H2O (1). The axial coordination of the CMP2- ligands through the N3 and O2 sites (free nitrogen and carbonyl groups) of the cytosine nucleobase and oxygen atoms of…

The timing of initial imaging in testicular cancer: impact on radiological findings and clinical decision making

2021

Background In testicular cancer determination of clinical stage and recommendation of therapeutic strategy after inguinal orchiectomy are based on primary imaging by CT-scan of the chest and CT- or MRI- abdomen. It has not been investigated so far, whether the imaging should be performed before or after primary testicular surgery. Staging before surgery means exposing all patients to CT radiation irrespective of ensured histologic malignancy while postoperative staging could pose a risk in biased clinical decision making by increased presence of unspecific lymph node enlargement caused by postsurgical effects. Therefore, we aimed to investigate the association between the timing of initial …

Switching dynamics of dark-pulse Kerr frequency comb states in optical microresonators

2021

Dissipative Kerr solitons are localized structures that exist in nonlinear optical cavities. They lead to the formation of microcombs - chip-scale frequency combs that could facilitate precision frequency synthesis and metrology by capitalizing on advances in silicon photonics. Previous demonstrations have mainly focused on anomalous dispersion cavities. Notwithstanding, localized structures also exist in the normal dispersion regime in the form of circulating dark pulses, but their physical dynamics is far from being understood. Here, we explore dark-pulse Kerr combs generated in normal dispersion optical microresonators and report the discovery of reversible switching between coherent dar…

Correlation-driven sub-3 fs charge migration in ionised adenine

2021

Sudden ionisation of a relatively large molecule can initiate a correlation-driven process dubbed charge migration, where the electron density distribution is expected to rapidly change. Capturing this few-femtosecond/attosecond charge redistribution represents the real-time observation of the electron correlation in the molecule. So far, there has been no experimental evidence of this process. Here we report on a time-resolved study of the correlation-driven charge migration process occurring in the bio-relevant molecule adenine after ionisation by a 15-35 eV attosecond pulse . We find that, the production of intact doubly charged adenine - via a shortly-delayed laser-induced second ionisa…
