Orthostatic Hemodynamic Changes in Brain Damage

Aim: to study orthostatic hemodynamic changes in patients with chronic disorders of consciousness after critical brain damage.Materials and methods. We studied 30 patients (10 women and 20 men) with chronic disorders of consciousness after severe brain damage aged 45±7 years, 10 of which were in the vegetative state (VS) and 20 had the minimally conscious state (MCS). The main causes of brain damage were traumatic brain injury (53% of patients) and cerebrovascular accidents (CVA) (23.3%). The rest of the patients had posthypoxic encephalopathy or were after brain tumor removal surgery. Passive orthostatic test (POT) 0° to 60° to 0° was performed using an electrically driven tilt table (Vario Line). Hemodynamic monitoring during the verticalization was done using a non-invasive oscillometric recording of blood pressure on the brachial artery, stroke volume (SV) and cardiac minute output (CMO) were measured by impedance cardiography with the multifunctional «Task Force Monitor 3010i» (CNSystem, Austria). Data were statistically analyzed using the Statistica 10 software package.Results. Orthostatic hemodynamic stability was found in 26 out of 30 patients with chronic disorders of consciousness after critical brain damage. It was manifested by stable systolic blood pressure (SBP) in tilted orthostatic and horizontal position (120.7±2.2 and 121.1±3.6 mmHg, respectively, P>0.05). Orthostatic hypotension was observed in 3 patients and postural tachycardia syndrome (PTS) in one patient. We compared orthostatic hemodynamic changes in the studied cohort versus published data on orthostatic hemodynamic changes uncluding POT revealed in patients with severe brain damage examined before and after brain death.Conclusion. Orthostatic stability of blood circulation can be maintained for a short period of time in patients surviving after critical diffuse brain damage associated with chronic disorders of consciousness. Critical brain damage resulting in brain death associates with a significant reduction of all hemodynamic parameters and severe orthostatic hypotension with restoration of initial blood pressure values when the patient is returned to the horizontal position.
Supporting Time-Sensitive and Best-Effort Traffic on a Common Metro Infrastructure

Considerable research and standardization efforts are being made to support time-sensitive traffic, e.g., generated by applications like Industry 4.0 and 5G fronthaul, on packet networks. This letter focuses on analyzing the impact of conveying time-sensitive traffic in operators’ networks when such traffic is mixed with best-effort traffic. Extensions to a continuous $G/G/1/k$ queue model are proposed to evaluate two different Ethernet technologies, synchronous and asynchronous, supporting time-sensitive flows in terms of their influence on the performance of best-effort traffic. Results highlight pros and cons of those technologies to protect best-effort performance.
Anatomical aspects of the taxonomy of sedges (Carex, Cyperaceae)

Patterns of variation in the anatomy of achene epidermis and leaves were examined to assess the utility of anatomical characters in systematic and phylogenetic studies of Carex and the Cyperaceae. This study was based primarily on a review of the available literature. In addition, foliar anatomy of species in Carex sect. Phacocystis was investigated and patterns of variation within the section were analyzed using a centroid cluster algorithm. Nearly all genera and all sections of Carex for which data are available include species with single conical silica bodies in the achene epidermal cells as well as species with more elaborate, presumably derived, silica bodies. Similarly, most sections within Carex include species that have hypostomatous leaves with a single layer of bulliform cells and that lack papillae, as well as species with amphistomatous leaves, papillose epidermal cells, or multiple bulliform cells. Application of the "common equals primitive" in group criterion for determining evolutionary p.
Training With Wii Balance Board for Dynamic Balance in Older Adults

Background and Purpose: Age-related muscle strength deterioration and decreased ability to react appropriately and regain balance after unexpected sudden disturbances and deficit they have in the use of responsible mechanisms to control the dynamic stability in response to a disturbance are important intrinsic risk factors for the fall. The main objective of this study is to verify the impact on the dynamic balance, through the Limits of Stability test, of a physical exercise program in older adults using the Nintendo Wii console. Methods: The sample consisted of a total of 12 patients. Pre and posttreatment measurements and assessments were carried out at the Laboratory of Motion Analysis, Biomechanics, Ergonomics and Motor Control (LAMBECOM) in the Faculty of Health Sciences of the Rey Juan Carlos University. Results and Conclusions: The results of this study show improvements in the scores of all the variables analyzed by Limits of Stability: RT, MVL, EPE, MXE and DCL. The results obtained seem to determine that the protocol used through training with the Nintendo Wii and its Wii Fit video game produced clinical improvements in postural control and dynamic balance and a positive impact on quality of life.
HISTOCHEMICAL IDENTIFICATION OF SKELETAL MUSCLE FIBER TYPE-SKELETAL MUSCLE IN NORMAL MEN AND RATS

By applying a histochemical method to demonstrate the myosin ATPase activity of the skeletal muscle of humans and rats after preincubation in acidic and alkaline media, the muscle fiber types could be identified. The human skeletal muscle fibers can be classified into 4 types (I, IIa, IIb and IIc). The rat skeletal muscle fibers can be distinguished into 5 types (Ia, Ib, IIa, IIb and IIc). By using 12 kinds of histological and histochemical staining methods, we studied the activities of several enzyems and their staining patterns in the various types of muscle fibers, and then calculated the percentage of each fiber type in humans.
Estimating the Rank of a Nonnegative Matrix Factorization Model for Automatic Music Transcription Based on Stein’s Unbiased Risk Estimator

In this paper, methods to estimate the number of basis vectors of the nonnegative matrix factorization (NMF) of automatic music transcription (AMT) systems are proposed. Previously, studies on NMF-based AMT have demonstrated that the number of basis vectors affects the performance and that the number of note events can be a good selection as the rank of NMF. However, many NMF-based AMT methods do not provide a method to estimate the appropriate number of basis vectors; instead, the number is assumed to be given in advance, even though the number of basis vectors significantly affects the algorithm’s performance. Recently, based on Bayesian methods, certain estimation algorithms for the number of basis vectors have been proposed; however, they are not designed to be used as music transcription algorithms but are components of specific NMF methods and thus cannot be used generally as NMF-based transcription algorithms. Our proposed estimation algorithms are based on eigenvalue decomposition and Stein’s unbiased risk estimator (SURE). Because the SURE method requires variance in undesired components as a priori knowledge, the proposed algorithms estimate the value using random matrix theory and first and second onset information in the input music signal. Experiments were then conducted for the AMT task using the MIDI-aligned piano sounds (MAPS) database, and these algorithms were compared with variational NMF, gamma process NMF, and NMF with automatic relevance determination algorithms. Based on experimental results, the conventional NMF-based transcription algorithm with the proposed rank estimation algorithms demonstrated enhanced F1 score performances of 2–3% compared to the algorithms. While the performance advantages are not significantly large, the results are meaningful because the proposed algorithms are lightweight, are easy to combine with any other NMF methods that require an a priori rank parameter, and do not have setting parameters that considerably affect the performance.
Are New Zealand's Nothofagus species in equilibrium with their environment?

Abstract. Past explanations of the large disjunctions in the distribution of New Zealand's four Nothofagus species have emphasized displacement during glacial cycles followed by slow re-occupation of suitable sites, or the effects of plate tectonics coupled with ecological and/or environmental limitations to further spread. In this study the degree of equilibrium between Nothofagus distribution and environment was compared with that of other widespread tree species by statistical analysis. Generalized additive regression models were used to relate species distribution data to estimates of temperature, solar radiation, soil water deficit, atmospheric humidity, lithology and drainage. For each species, the amount of spatial patterning remaining unexplained by environment was assessed by adding a variable describing species presence/absence on adjacent plots. Results indicate that Nothofagus species occur more frequently in environments suboptimal for tree growth, i.e. having various combinations of cool temperatures, low winter solar radiation, high root-zone water deficit, low humidity, and infertile granitic substrates. Despite these demonstrated preferences, they exhibit substantially more spatial clustering which is unexplained by environment, than most other widespread tree species. Predictions formed from regressions using environment alone confirm that several major Nothofagus disjunctions are not explicable in terms of the environmental factors used in this analysis, but more likely reflect the effects of historic displacement coupled with slowness to invade forest dominated by more rapidly dispersing endomycorrhizal species. The technique used in this study for detecting residual spatial autocorrelation after fitting explanatory variables has potentially wide application in other studies where either regression or ordination techniques are used for analysis of compositional data.
Intra‐specific variability of the morphology in a single population of the seal parasite Contracaecum osculatum (Rudolphi) (Nematoda, Ascaridoidea), with a redescription of the species

Contracaecum spp. are common parasites of seals and piscivorous birds. The world‐wide distribution which has been attributed to the species C. osculatum needs verification. In the present study thc intra‐specific variability of some taxonomically significant characters was studied in this species. Features analysed include the length and morphology of the distal end of the spicules, the number of proximal caudal papillae and the number of papillae in the region of the first 25 cuticular transverse striae anterior to the cloaca, delined as the Pts zone (precloacal transverse striae zone). The spicules reach their maximum length only in fully grown worms. while the morphology of the distal end of the spicule is determined early in the life of adult male worms. Included is a detailed analysis of the observed morphometric variability in the distal end of the spicule. The number of cuticular transverse striae in relation to papillae in the Pts zone remains constant in different length classes of the parasite. A redescription of the parasite is provided, bascd on material obtained from grey seals in the Baltic Sea, to serve as a basis for discussions on the taxonomy of the genus.
Hydria: An Online Data Lake for Multi-Faceted Analytics in the Cultural Heritage Domain

Advancements in cultural informatics have significantly influenced the way we perceive, analyze, communicate and understand culture. New data sources, such as social media, digitized cultural content, and Internet of Things (IoT) devices, have allowed us to enrich and customize the cultural experience, but at the same time have created an avalanche of new data that needs to be stored and appropriately managed in order to be of value. Although data management plays a central role in driving forward the cultural heritage domain, the solutions applied so far are fragmented, physically distributed, require specialized IT knowledge to deploy, and entail significant IT experience to operate even for trivial tasks. In this work, we present Hydria, an online data lake that allows users without any IT background to harvest, store, organize, analyze and share heterogeneous, multi-faceted cultural heritage data. Hydria provides a zero-administration, zero-cost, integrated framework that enables researchers, museum curators and other stakeholders within the cultural heritage domain to easily (i) deploy data acquisition services (like social media scrapers, focused web crawlers, dataset imports, questionnaire forms), (ii) design and manage versatile customizable data stores, (iii) share whole datasets or horizontal/vertical data shards with other stakeholders, (iv) search, filter and analyze data via an expressive yet simple-to-use graphical query engine and visualization tools, and (v) perform user management and access control operations on the stored data. To the best of our knowledge, this is the first solution in the literature that focuses on collecting, managing, analyzing, and sharing diverse, multi-faceted data in the cultural heritage domain and targets users without an IT background.

Oligonucleotide interactions. III. Circular dichroism studies of the conformation of deoxyoligonucleolides

The circular dichroism (CD) spectra of the four usual deoxymononucleosides, all sixteen deoxydinucleotides, and a number of trinucleotides have been measured. The dimer spectra are quite different from the sum of the spectra of their constituent monomers. This indicates the presence of base‐stacked conformations analogous to those found for ribonucleoside diphosphates. The CD spectra of several deoxytrinucleotide diphosphates and single‐strand f 1 DNA can be calculated fairly well by using a semi‐empirical nearest‐neighbor approach. There is little or no effect of terminal phosphate or of salt concentration on the optical properties of most deoxy oligomers. The possibility of simultaneous analysis of mixtures of deoxypurine or deoxypyrimidine sequence isomers has been examined. This seems to be a viable approach for the analysis of purine runs but cannot promise much success for pyrimidine runs.
PROGRESSIVE FAILURE ANALYSIS OF HELICOPTER ROTOR BLADE UNDER AEROELASTIC LOADING

Unlike metal structure, composite structures don’t give any clue till the fatal final collapse. The problem is more complicated when applied load on the structure is aeroelastic in nature. Under such loading, composite laminate experiences stresses. The first layer failure happens when stresses in the weakest ply exceed the allowable strength of the laminate. This initial layer-based failure changes overall material characteristics. It is important now to degrade the composite laminate characteristics for the subsequent failure prediction. The constitutive relations are required to be updated by the reduction in stiffness. The rest of the undamaged laminates continue to take the load till the updated strength is reached. In the present work, layer wise progressive failure analysis under aeroelastic loading has been performed by the inclusion of different failure criteria which allow for the identification of the location of the failure. ANSYS APDL environment has been used to model geometry of helicopter rotor. Under the loading conditions, stresses are calculated in the blade. Using stress tensor and failure criteria, failure location and modes have been predicted. It has been found that failure starts at higher speeds and failure starts from the root chord and tend towards the tip chord.
Institutional continuum in the context of the pandemic

The article considers institutional responses to the challenges created by COVID­19 pandemic. The comparison of discrete structural alternatives is one of the most important principles of institutional analysis. It means that policymakers and researchers rely on a countable set of legal options in the course of comparison of different institutions designed to solve one or another problem. COVID­19 pandemic provoked the elaboration of “intermediate” normative solutions, thus changing the legal framework and leading to the formation of the short­term “institutional continuum” instead of the established spectrum of alternatives.
Incremental Instance-Oriented 3D Semantic Mapping via RGB-D Cameras for Unknown Indoor Scene

Scene parsing plays a crucial role when accomplishing human-robot interaction tasks. As the “eye” of the robot, RGB-D camera is one of the most important components for collecting multiview images to construct instance-oriented 3D environment semantic maps, especially in unknown indoor scenes. Although there are plenty of studies developing accurate object-level mapping systems with different types of cameras, these methods either process the instance segmentation problem in completed mapping or suffer from a critical real-time issue due to heavy computation processing required. In this paper, we propose a novel method to incrementally build instance-oriented 3D semantic maps directly from images acquired by the RGB-D camera. To ensure an efficient reconstruction of 3D objects with semantic and instance IDs, the input RGB images are operated by a real-time deep-learned object detector. To obtain accurate point cloud cluster, we adopt the Gaussian mixture model as an optimizer after processing 2D to 3D projection. Next, we present a data association strategy to update class probabilities across the frames. Finally, a map integration strategy fuses information about their 3D shapes, locations, and instance IDs in a faster way. We evaluate our system on different indoor scenes including offices, bedrooms, and living rooms from the SceneNN dataset, and the results show that our method not only builds the instance-oriented semantic map efficiently but also enhances the accuracy of the individual instance in the scene.
A New Genus and Species of Scincid Lizards from Vietnam: The First Asiatic Skink with Double Rows of Basal Subdigital Pads

A small lygosomine skink, from tropical rain forests of southern Vietnam, differs primarily from other Asiatic scincids in having a double rows of subdigital pads. There are presumably associated with its arboreal mode of life. Other scale characters allow placement of the new monotypic genus close to the lygosomine genera Lipinia Gray and Scincella Mittleman (group 1 of Greer, 1974). A taxonomically very complicated group of lygosomine scincid lizards of the genus Leiolo- pisma and its relatives was revised by Greer (1974) in detail. Based on osteological and mor- phological characters, these lizards were placed into three major generic groups. Representatives of the genera Scincella and Lipinia (Greer's group I) and of Emoia (Greer's group II) inhabit the mainland of the south-east Asia, including Vi- etnam.
User Identity Linkage via Co-Attentive Neural Network From Heterogeneous Mobility Data

Online services are playing critical roles in almost all aspects of users’ life. Users usually have multiple online identities (IDs) in different online services. In order to fuse the separated user data in multiple services for better business intelligence, it is critical for service providers to link online IDs belonging to the same user. On the other hand, the popularity of mobile networks and GPS-equipped smart devices have provided a generic way to link IDs, i.e., utilizing the mobility traces of IDs. However, linking IDs based on their mobility traces has been a challenging problem due to the highly heterogeneous, incomplete and noisy mobility data across services. In this paper, we propose DPLink, an end-to-end deep learning based framework, to complete the user identity linkage task for heterogeneous mobility data collected from different services with different properties. DPLink is made up by a feature extractor including a location encoder and a trajectory encoder to extract representative features from trajectory and a comparator to compare and decide whether to link two trajectories as the same user. Particularly, we propose a pre-training strategy with a simple task to train the DPLink model to overcome the training difficulties introduced by the highly heterogeneous nature of different source mobility data. Besides, we introduce a multi-modal embedding network and a co-attention mechanism in DPLink to deal with the low-quality problem of mobility data. By conducting extensive experiments on two real-life ground-truth mobility datasets with eight baselines, we demonstrate that DPLink outperforms the state-of-the-art solutions by more than 15 percent in terms of hit-precision. Moreover, it is expandable to add external geographical context data and works stably with heterogeneous noisy mobility traces.
Morphological and Biochemical Systematics of Australian Freashwater and Estuarine Percichthyid Fishes

The taxonomy and evolutionary relationships of six Australian species of the family Percichthyidae have been investigated using data obtained from comparative morphological examination of preserved specimens and from electrophoretic detection of variation in proteins extracted from liver tissue. Members of the genera Maccullochella, Plectroplites, Macquaria and Percalates form a group of generalized percoid species that have presumably colonized Australian fresh waters from marine origins. On morphological grounds the group is here considered to belong in the basal percoid family Percichthyidae rather than in the specialized family Serranidae to which it has been previously assigned. Some doubt remains, however, as to the affinities of the genus Maccullochella. Evidence from morphological studies, and from electrophoretic analysis of protein variation at 19 genetic loci, indicates that Maccullochella differs extensively from the other genera and that the two subgroups so formed represent separate invasions of fresh waters by already distinct marine ancestors. The Australian genera Plectroplites, Macquaria and Percalates form a closely related monophyletic group which can be assigned to a single genus. The oldest available name for such a genus is Macquavia Cuvier and Valenciennes, 1830. Morphological and electrophoretic evidence supports the distinction of two species of Maccullochella, but no significant variation was detected between Percalates specimens initially identified as either P. colonorum or P. novemaculeatus.
