Drought is an extreme meteorological phenomenon involving serious economic consequences. In the Czech Lands, it is reflected in significant reductions in agricultural productivity, lack of water for hygiene and industry, and impacts of forest management. Mean monthly temperature and precipitation series created for the Czech Lands for 1805–2012 were used to calculate spring (MAM) and summer (JJA) drought indices (SPI-1, SPI-12, SPEI-1, SPEI-12, Z-index and PDSI), which were then used for further analyses. ...

Mature larvae and pupae of Coniocleonus (Plagiographus) nigrosuturatus (Goeze, 1777) (Curculionidae: Lixinae: Cleonini) are described and compared with three other cleonine taxa with known larvae. The biology of the species was studied in Romania, Hungary and Slovakia. Common Stork’s-bill (Erodium cicutarium) (Geraniaceae) is identified as a host plant of both larvae and adults of this weevil. The weevil is very likely monophagous, and previous records of thyme (Thymus sp., Lamiaceae) as the host plant ...

This study reports on 3.5 years (2008–2011) of actual evapotranspiration (ET) measurements of two short-rotation poplar coppice (SRC) plantations in comparison with two reference grass covers (clipped turf grass and permanent grassland) in a rain-fed area of the Czech–Moravian Highlands in the Czech Republic. The Bowen ratio/energy balance method (BREB) was used to measure the ET of all the four investigated covers. Although the ET of the SRCs sometimes exceeded that of grass vegetation or the reference ...

The plantations of short rotation coppice (SRC) usually based on poplar or willow species are promising source of biomass for energy use. To contribute to decision-making process where to establish the plantations we evaluated the water consumption and its relation to biomass yields of poplar hybrid clone J-105 (Populus nigra x P. maximowiczii) in representative conditions for Czech-Moravian Highlands. Water availability is usually considered as one of the main constraints of profitable SRC culture ...

Objective: The aim of the present study was to investigate if prospective memory (PM) is impaired in idiopathic rapid eye movement (REM) sleep behavior disorder (iRBD). RBD is a parasomnia characterized by dream enactment and by REM sleep without muscle atonia. iRBD is considered as the initial stage of neurodegeneration with pathological storage of alpha-synuclein. Method: Sixty iRBD patients with polysomnography-confirmed RBD without parkinsonism and dementia and 30 demographically matched normal ...

Abstract Isolated REM sleep behavior disorder (iRBD) is an early stage of synucleinopathy with most patients progressing to Parkinson's disease (PD) or related conditions. Quantitative susceptibility mapping (QSM) in PD has identified pathological iron accumulation in the substantia nigra (SN) and variably also in basal ganglia and cortex. Analyzing whole‐brain QSM across iRBD, PD, and healthy controls (HC) may help to ascertain the extent of neurodegeneration in prodromal synucleinopathy. 70 de novo ...

Abnormal motor manifestations in REM sleep are the most visible feature of idiopathic REM sleep behavior disorder (iRBD), which precedes the overt alpha-synucleinopathy. The aim of this study was to perform a systematic visual analysis of the motor events (ME) captured during video-polysomnography, and clarify their relation to the disease severity. Thirty-four iRBD patients (5 women, 29 men; age 67.7 ± 7.2) with a mean follow-up duration 2.9 ± 1.1 years. and 33 controls (10 women, 23 men; age 61.5 ± 8.2) ...

During emergency response, emergency management and its command and control system are particularly challenged as the responding taskforce puts countermeasures in place intensively and dynamically. To respond effectively these countermeasures are typically coordinated through collaborative work of commanding staff. Information seeking, communication, and data sharing are essential elements of this collaborative command and control work. The traditional research methods used in command and control ...

A 44–year-old woman was diagnosed as having unilateral multiple progradient pigmented macules and papules of the upper extremity and adjacent part of the back. Microscopically increased amounts of melanin and melanocytes in the basal layer of the epidermis in the early developmental stage of macules were seen. Combinations of blue nevus with junctional or compound nevus or with a simple proliferation of melanocytes in the epidermis were present in the papules. The question of prognosis is discussed.

Abstract Contemporary crisis management studies often make use of the concept of resilience. However, resilience as a term has a wide variety of meanings and has been criticized as lacking operationalization and empirical validation. The current study aimed to link resilience concepts to observable behaviour within a disaster medicine management system. Resilience concepts, captured in so‐called capability cards and further operationalized into six resilience prerequisites, were used in the study. ...

We derive scalar effective field theories - Lagrangians, symmetries, and all - from on-shell scattering amplitudes constructed purely from Lorentz invariance, factorization, a fixed power counting order in derivatives, and a fixed order at which amplitudes vanish in the soft limit. These constraints leave free parameters in the amplitude which are the coupling constants of well-known theories: Nambu-Goldstone bosons, Dirac-Born-Infeld scalars, and Galileons. Moreover, soft limits imply conditions on ...

We construct the flavor-ordered Feynman rules for various parameterizations of the SU(N) fields U (x), write down the Berends-Giele relations for the semi-on-shell currents and discuss their efficiency for the amplitude calculation in comparison with those of renormalizable theories. We also present an explicit form of the partial amplitudes up to ten external particles. ...

It is well-known that the standard BCFW construction cannot be used for on-shell amplitudes in effective field theories due to bad behavior for large shifts. We show how to solve this problem in the case of the SU(N) non-linear sigma model, i.e. non-renormalizable model with infinite number of interaction vertices, using scaling properties of the semi-on-shell currents, and we present new on-shell recursion relations for all on-shell tree-level amplitudes in this theory.
