Отдельное место в исследовании занимает иерархизация радиационных и нерадиационных методов исследования. Использование эхографического и эндоскопического методов исследования привело к снижению коллективной дозы радиации населения. Увеличение основных показателей деятельности служб лучевой и эндоскопической диагностики в исследовании желудочно-кишечного тракта произошло за счет роста обращаемости в лечебные учреждения и частичной необоснованности их назначения

Treatment methods in fingertips injuries

Secţia microchirurgie, CNŞPMU, Conferinţa Naţională în cadrul Asociaţiei Ortopezilor – Traumatologi din Republica Moldova ”Actualităţi în microchirurgia reconstructivă”, Chișinău, Republica MoldovaIn this study different methods of treatment are presented in 405 patients with fingertip ingeries, operated in the department of microsurgery during the period of 2007/2010 years. The main objectives of treatment were: 1) wound closure, 2) maximal sensitive recovery, 3) keeping the finger length, 4) maintenance of joints function 5) achieve a satisfactory cosmetic look.Plastia defectelor în amputaţiile falangelor terminale ale degetelor.

Particularităţile radiodiagnosticului în traumatismele articulaţiei acromioclaviculare

Centrul Republican de Diagnosticare Medicală, Spitalul de Traumatologie şi Ortopedie, Centrul Naţional Ştiinţifico-Practic Medicina de UrgenţăAcromio-clavicular joint is important in the functioning of the upper limb and acromio-clavicular injuries represent a problem in contemporary traumatology. In order to evaluate the acromio-clavicular trauma it is necessary to examine ACJ bilateral, using multiple imaging methods (standardized, stress, axial). The imaging diagnosis of ACJ injuries is important to make an appropriate decision about treatment methods.Ключично-акромиальный сустав (КАС) играет большую роль в деятельности верхней конечности, а ее повреждение является важной проблемой современной травматологии. Для оценки тяжести и сложности травматических повреждении акромио-ключичной сочленения необходимо обследование обеих КАС с использованием разных укладок (стандартные, стрессовые и аксиальные). Установление повреждения КАС с помощью рентгенодиагностического метода является очень важным моментом в выборе самого эффективного метода лечения

Relating different Polynomial-LWE problems

In this paper we focus on Polynomial Learning with Errors (PLWE). This problem is parametrized by a polynomial and we are interested in relating the hardness of the $\text{PLWE}^f$ and $\text{PLWE}^h$ problems for different polynomials $f$ and $h$. More precisely, our main result shows that for a fixed monic polynomial $f$, $\text{PLWE}^{f\circ g}$ is at least as hard as $\text{PLWE}^f$, in both search and decision variants, for any monic polynomial $g$. As a consequence, $\text{PLWE}^{\phi_n}$ is harder than $\text{PLWE}^{f},$ for a minimal polynomial $f$ of an algebraic integer from the cyclotomic field $\mathbb{Q}(\zeta_n)$ with specific properties. Moreover, we prove in decision variant that in the case of power-of-2 polynomials, $\text{PLWE}^{\phi_n}$ is at least as hard as $\text{PLWE}^f,$ for a minimal polynomial $f$ of algebraic integers from the $n$th cyclotomic field with weaker specifications than those from the previous result

Structure from motion photogrammetry in forestry : a review

AbstractPurpose of ReviewThe adoption of Structure from Motion photogrammetry (SfM) is transforming the acquisition of three-dimensional (3D) remote sensing (RS) data in forestry. SfM photogrammetry enables surveys with little cost and technical expertise. We present the theoretical principles and practical considerations of this technology and show opportunities that SfM photogrammetry offers for forest practitioners and researchers.Recent FindingsOur examples of key research indicate the successful application of SfM photogrammetry in forestry, in an operational context and in research, delivering results that are comparable to LiDAR surveys. Reviewed studies have identified possibilities for the extraction of biophysical forest parameters from airborne and terrestrial SfM point clouds and derived 2D data in area-based approaches (ABA) and individual tree approaches. Additionally, increases in the spatial and spectral resolution of sensors available for SfM photogrammetry enable forest health assessment and monitoring. The presented research reveals that coherent 3D data and spectral information, as provided by the SfM workflow, promote opportunities to derive both structural and physiological attributes at the individual tree crown (ITC) as well as stand levels.SummaryWe highlight the potential of using unmanned aerial vehicles (UAVs) and consumer-grade cameras for terrestrial SfM-based surveys in forestry. Offering several spatial products from a single sensor, the SfM workflow enables foresters to collect their own fit-for-purpose RS data. With the broad availability of non-expert SfM software, we provide important practical considerations for the collection of quality input image data to enable successful photogrammetric surveys

Middle-Product Learning with Rounding Problem and Its Applications

International audienceAt CRYPTO 2017, Roşca et al. introduce a new variant of the Learning With Errors (LWE) problem, called the Middle-Product LWE (MP-LWE). The hardness of this new assumption is based on the hardness of the Polynomial LWE (P-LWE) problem parameterized by a set of polynomials, making it more secure against the possible weakness of a single defining polynomial. As a cryptographic application, they also provide an encryption scheme based on the MP-LWE problem. In this paper, we propose a deterministic variant of their encryption scheme, which does not need Gaussian sampling and is thus simpler than the original one. Still, it has the same quasi-optimal asymptotic key and ciphertext sizes. The main ingredient for this purpose is the Learning With Rounding (LWR) problem which has already been used to deran-domize LWE type encryption. The hardness of our scheme is based on a new assumption called Middle-Product Computational Learning With Rounding, an adaption of the computational LWR problem over rings, introduced by Chen et al. at ASIACRYPT 2018. We prove that this new assumption is as hard as the decisional version of MP-LWE and thus benefits from worst-case to average-case hardness guarantees
