Connectivity Predicts Presence but Not Population Density in the Habitat-Specific Mountain Lizard Iberolacerta martinezricai
Authors: Lizana-Ciudad Diego , Colino-Rabanal Víctor J. , Arribas Óscar J. , Lizana Miguel
Published: March 2021

The Batuecan lizard Iberolacerta martinezricai is a critically endangered species due to its significantly reduced distribution, which is restricted to the scree slopes (SS) of a few mountain peaks within the Batuecas-Sierra de Francia Natural Park (western Spain). Given its high specialisation in this type of discontinuous habitat, the long-term conservation of the species requires maintaining the connectivity between populations. This study analyses the contribution of connectivity, as well as other patch-related factors, in the distribution and density patterns of the species. With this aim, 67 SS were sampled by line transects from May to October 2018. Each SS was characterised using variables indicative of the microhabitat conditions for the lizard. Inter-SS connectivity was quantified using graph theory for seven distances. Generalised linear models (GLMs) were performed for both presence and density. Model results showed that while connectivity was a relevant factor in the presence of lizards, density only involved patch-related variables. Discrepancies probably occurred because the factors influencing presence operate on a wider scale than those of abundance. In view of the results, the best-connected SS, but also those where the lizard is most abundant and from which more dispersed individuals are likely to depart, seem to be the essential patches in any conservation strategy. The results may also be relevant to other species with habitat-specific requirements.

Published: March 2021

The cultivated peanut (Arachis hypogaea L.) is one of the most widely consumed legumes globally due to its nutrient content, taste, and affordability. Nutrient composition and consumer preference were determined for twenty local farmer (landrace) and commercial peanut varieties grown in the Nakaseke and Nakasongola districts of the central wooded savanna of Uganda through sensory and laboratory evaluation. Significant differences in nutrient content (p < 0.05) among peanut varieties were found within and across sites. A significant relationship between nutrient content and consumer preference for varieties within and across sites was also realized (Wilk’s lambda = 0.05, p = 0.00). The differences in nutrient content influenced key organoleptic characteristics, including taste, crunchiness, appearance, and soup aroma, which contributed to why consumers may prefer certain varieties to others. Gender differences in variety selection were significantly related to consumer preference for the crunchiness of roasted peanut varieties (F = 5.7, p = 0.016). The results imply that selecting different varieties of peanuts enables consumers to receive different nutrient amounts, while experiencing variety uniqueness. The promotion of peanut intraspecific diversity is crucial for improved nutrition, organoleptic appreciation and the livelihood of those engaged in peanut value chains, especially for the actors who specialize in different peanut products. The conservation of peanut diversity will ensure that the present and future generations benefit from the nutritional content and organoleptic enjoyment that is linked to unique peanut varieties.

Published: March 2021

What this research may achieve points towards the need to progressively improve the reasonableness in establishing Social Welfare Agencies (SWAs). The service capacity of SWAs is far below the population of the level III extremely disabled. This is a serious problem. This evaluation can assist social welfare and public health departments to determine what locations to approve for establishing SWAs in the short term and plan for new SWAs more precisely, as well as rein in budgetary priorities. As an illustration, in considering the distance between SWAs and the extremely disabled, the service quality of SWAs and fairness in the planning have to be taken into account. Introducing a Service Quantity Needed-Index for SWAs (SNIS) into the current measure of approving and planning new SWAs shall assist the departments in distributing social welfare resources to areas most in need of help. In addition, using the modified data to recalculate SNIS can examine needs regularly. Employing basic statistical areas for short-term applications in Taipei City SWA projects, considering the distance between SWAs and the extremely disabled, the agencies’ service quality and fairness in the planning of SWAs need to receive more attention. Previous research mostly employed straight-line distances rather than road distances. To a certain extent, this overlooked the actual capacity of roads as well as led to some degree of discrepancies in evaluations. This essay focuses on calculating SNIS, mainly towards guiding the establishment of facilities and concretely proposing how to optimize their locations. Future research can add in needs at that time in accordance with current evaluation results to propose plans to optimize the locations, or maybe integrate weights of disability to adjust multiple requirements of SWAs.

Authors: Kim Serena Y. , Ganesan Koushik , Dickens Princess , Panda Soumya
Published: March 2021

Public acceptance and support for renewable energy are important determinants of the low-carbon energy transition. This paper examines public sentiment toward solar energy in the United States using data from Twitter, a micro-blogging platform on which people post messages, known as tweets. We filtered tweets specific to solar energy and performed a classification task using Robustly optimized Bidirectional Encoder Representations from Transformers (RoBERTa). Our RoBERTa-based sentiment classification model, fine-tuned with 6300 manually annotated tweets specific to solar energy, attains 80.2% accuracy for ternary (positive, neutral, or negative) classification. Analyzing 266,686 tweets during the period of January to December 2020, we find public sentiment varies widely across states (Coefficient of Variation =164.66%). Within the study period, the Northeast U.S. region shows more positive sentiment toward solar energy than did the South U.S. region. Public opinion on solar energy is more positive in states with a larger share of Democratic voters in the 2020 presidential election. Public sentiment toward solar energy is more positive in states with consumer-friendly net metering policies and a more mature solar market. States that wish to gain public support for solar energy might want to consider implementing consumer-friendly net metering policies and support the growth of solar businesses.
Dynamical Simulation of Effective Stem Cell Transplantation for Modulation of Microglia Responses in Stroke Treatment
Authors: Alqarni Awatif Jahman , Rambely Azmin Sham , Hashim Ishak
Published: March 2021

Stem cell transplantation therapy may inhibit inflammation during stroke and increase the presence of healthy cells in the brain. The novelty of this work, is to introduce a new mathematical model of stem cells transplanted to treat stroke. This manuscript studies the stability of the mathematical model by using the current biological information on stem cell therapy as a possible treatment for inflammation from microglia during stroke. The model is proposed to represent the dynamics of various immune brain cells (resting microglia, pro-inflammation microglia, and anti-inflammation microglia), brain tissue damage and stem cells transplanted. This model is based on a set of five ordinary differential equations and explores the beneficial effects of stem cells transplanted at early stages of inflammation during stroke. The Runge–Kutta method is used to discuss the model analytically and solve it numerically. The results of our simulations are qualitatively consistent with those observed in experiments in vivo, suggesting that the transplanted stem cells could contribute to the increase in the rate of ant-inflammatory microglia and decrease the damage from pro-inflammatory microglia. It is found from the analysis and simulation results that stem cell transplantation can help stroke patients by modulation of the immune response during a stroke and decrease the damage on the brain. In conclusion, this approach may increase the contributions of stem cells transplanted during inflammation therapy in stroke and help to study various therapeutic strategies for stem cells to reduce stroke damage at the early stages.
Multi-Valent Protein Hybrid Pneumococcal Vaccines: A Strategy for the Next Generation of Vaccines
Authors: Scott Ninecia R. , Mann Beth , Tuomanen Elaine I. , Orihuela Carlos J.
Published: March 2021

Streptococcus pneumoniae (Spn) is a bacterial pathogen known to colonize the upper respiratory tract and cause serious opportunistic diseases such as pneumonia, bacteremia, sepsis and meningitis. As a consequence, millions of attributable deaths occur annually, especially among infants, the elderly and immunocompromised individuals. Although current vaccines, composed of purified pneumococcal polysaccharide in free form or conjugated to a protein carrier, are widely used and have been demonstrated to be effective in target groups, Spn has continued to colonize and cause life-threatening disease in susceptible populations. This lack of broad protection highlights the necessity of improving upon the current “gold standard” pneumococcal vaccines to increase protection both by decreasing colonization and reducing the incidence of sterile-site infections. Over the past century, most of the pneumococcal proteins that play an essential role in colonization and pathogenesis have been identified and characterized. Some of these proteins have the potential to serve as antigens in a multi-valent protein vaccine that confers capsule independent protection. This review seeks to summarize the benefits and limitations of the currently employed vaccine strategies, describes how leading candidate proteins contribute to pneumococcal disease development, and discusses the potential of these proteins as protective antigens—including as a hybrid construct.
Removal of Microplastics from Waters through Agglomeration-Fixation Using Organosilanes—Effects of Polymer Types, Water Composition and Temperature
Authors: Sturm Michael Toni , Horn Harald , Schuhen Katrin
Published: March 2021

Due to the fact, that microplastics are a global environmental problem, new ways for their removal from water, soil and air need to be developed. New materials in combination with easy to implement technologies for microplastic removal come into the focus of scientific studies and engineering, especially for application in water resources. In our comparative case study, the effects of water composition and temperature on the agglomeration-fixation reaction of microplastics using organosilanes were examined. We compared biologically treated municipal wastewater, seawater and demineralized water at temperatures ranging from 7.5–40 °C. Temperature variations and tested water compositions showed no negative effect on microplastic removal. The residues of the organosilanes remaining in the water after the fixation process were monitored using ICP-OES and DOC measurements. Only one of the organosilanes tested showed no dissolved residues in the waters. Microplastic encompasses a multitude of different types of polymers with different properties and surface chemistries. Therefore, we compared the efficiency of the process for polyethylene, polypropylene, polyamide, polyester, and polyvinylchloride as examples of common polymer types with different chemical compositions. A strong effect of the polarity of microplastics and organosilanes on removal efficiency was observed. The organic groups of organosilanes can be chemically adapted to different polymer types.
The Field-Scale Investigation of the Low Mobility of Drainage Canal Sediments Polluted by Copper in Lowland Area of Croatia
Authors: Leko Kos Marija , Tadić Lidija
Published: March 2021

The sedimentation of drainage canals is a common process and its intensity depends on several geographical and hydrological factors. Drainage canal sediments are frequently polluted by heavy metals or other pollutants; they need to be periodically dredged and ultimately, have to be safely disposed of. Furthermore, pollution in smaller drainages may go undetected because under the Water Framework Directive (Directive 2000/60/EC), catchment areas < 10 km2 do not require monitoring. We investigated the hypothesis that water resources of small sub-catchments exposed to agricultural pollutants accumulate sediment for a longer period (several years) and severely enhance environmental risks. We analyzed the data on sediment mobility in drainage canals for a small lowland catchment in Croatia during 2013–2017. We conducted sediment transport modelling for actual precipitation episodes of a 10-year return period and design precipitation of a 50-year return period. The results indicated that sediments and associated copper pollution persist at the canal bottom for several years, which increases the risk of polluting groundwater and the environment in general. Only copper present at the maximum downstream section of the canal has the possibility of moving to the recipient stream and would only be detected in catchment areas bigger than 10 km2. We proved that smaller water bodies evaluated according to monitoring standards prescribed for the closest larger water can enhance environmental risks.
A Hybrid Software Defined Networking-Based Load Balancing and Scheduling Mechanism for Cloud Data Centers
Authors: Kadim Umniah N. , Mohammed Imad J.
Published: March 2021

Cloud data centers provide various services using efficient and economic infrastructure to facilitate the work of IT providers, companies and different end users. But they may suffer from congestion due to the poor distribution of traffic load among the network links and consequently diminish the network performance. Software defined networking is a modern network technology described as a promising solution for the problem of cloud data center congestion. Software defined networking is distinguished in separating the control plane from the data plane and depends on centralized network control. The current paper introduces an optimized software defined networking-based load balancing and scheduling mechanism called the software defined networking load balance mechanism for cloud data center networks that benefits from the programmable abilities of software defined networking. For the performance evaluation of software defined networking load balance mechanism experiments, a common fat-tree topology is used as a data center network running on Mininet emulator under the ryusdn-controller. The performance results and comparisons of software defined networking load balance mechanism show an improvement in network throughput, link utilization and reduction in round trip time delay.
Analysis of tissue displacement induced by high-intensity focused ultrasound exposure for coagulation monitoring
Authors: Yamamoto Mariko , Yoshizawa Shin
Published: March 2021

Decorrelation between two ultrasound images has been investigated for real-time monitoring of lesion formation caused by high-intensity focused ultrasound (HIFU) exposure. However, the origin of the decorrelation remains unclear. In this study, the distributions of tissue displacement were obtained from numerical simulation and experimental data, and the latter was compared to the decorrelation map. The results show the possibility that decorrelation of ultrasonic signals can be explained by thermal expansion and apparent displacement caused by the temperature dependence of the speed of sound.

Authors: Manchikanti Laxmaiah
Published: March 2021

Background: Chronic spinal pain is common along with numerous modalities of diagnostic and
therapeutic interventions utilized, creating a health care crisis. Facet joint injections and epidural
injections are the 2 most commonly utilized interventions in managing chronic spinal pain. While
the literature addressing the effectiveness of facet joint nerve blocks is variable and emerging,
there is paucity of literature on adverse effects of facet joint nerve blocks.
Study Design: A prospective, non-randomized study of patients undergoing interventional
techniques from May 2008 to December 2009.

Prescription Opioid Abuse in Chronic Pain:
A Review of Opioid Abuse Predictors and
Strategies to Curb Opioid Abuse
Authors: Sehgal Nalini
Published: March 2021

Both chronic pain and prescription opioid abuse are prevalent and continue to exact a heavy
toll on patients, physicians, and society. Individuals with chronic pain and co-occurring
substance use disorders and/or mental health disorders, are at a higher risk for misuse of
prescribed opioids. Opioid abuse and misuse occurs for a variety of reasons, including self
medication, use for reward, compulsive use because of addiction, and diversion for profit.
Treatment approaches that balance treating chronic pain while minimizing risks for opioid
abuse, misuse, and diversion are much needed. The use of chronic opioid therapy for chronic
noncancer pain has increased dramatically in the past 2 decades in conjunction with a marked
increase in the abuse of prescribed opioids and accidental opioid overdoses. Consequently,
a validated screening instrument that provides an effective and rational method of selecting
patients for opioid therapy, predicting risk, and identifying problems once they arise could
be of enormous benefit. Such an instrument could potentially curb the risk of iatrogenic
addiction. Although several screening instruments and strategies have been introduced
in the past decade, there is no single test or instrument that can reliably and accurately
predict patients who are not suitable for opioid therapy or identify those who need increased
vigilance or monitoring during therapy.
At present, screening for opioid abuse includes assessment of premorbid and comorbid
substance abuse; assessment of aberrant drug-related behaviors; risk factor stratification; and
utilization of opioid assessment screening tools. Multiple opioid assessment screening tools
and instruments have been developed by various authors. In addition, urine drug testing,
monitoring of prescribing practices, prescription monitoring programs, opioid treatment
agreements, and utilization of universal precautions are essential. Presently, a combination
of strategies is recommended to stratify risk, identify and understand aberrant drug related
behaviors, and tailor treatments accordingly.
This manuscript will review the current state of knowledge regarding the growing problem
of opioid abuse and misuse; known risk factors; and methods of predicting, assessing,
monitoring, and addressing opioid abuse and misuse in patients with chronic noncancer pain.

A Novel Pilot Spoofing Scheme via Intelligent Reflecting Surface Based On Statistical CSI
Authors: yang jie , Ji Xinsheng , Wang Feihu , Huang Kaizhi , Zhou You
Published: March 2021

Pilot spoofing attack brings new challenges to the physical layer secure transmission. However, since the inherent characteristics of wireless environment have not changed, active eavesdropping can be detected based on prior information. Intelligent reflecting surface (IRS), with the real-time programmable features for wireless channels, provides new possibilities for effective pilot spoofing. In this paper, the IRS is deployed near the legitimate users and the control strategy is embeded into the legitimate communication process under time-division duplex mode to assist eavesdroppers to conduct pilot spoofing. By setting different phase shifts at the IRS during the uplink phase and downlink phase, the channel reciprocity disappears, and thus secure beamforming vector is biased towards the eavesdropper. Furthermore, in order to overhear more information, the average secrecy rate minimization problem based on statistical channel state information is established by carefully designing the phase shifts, which is non-trivial to solve. With alternating optimization and Charnes-Cooper transformation technique, the original problem is transformed into convex form and a near optimal solution is achieved. Finally, simulation results show that our proposed scheme can pose serious secure threat without any energy footprint. What's more, if the IRS is not utilized by the internal users properly, it will bring more threat.

Garbage was defined as the residue of people's daily activities. In the social environment, to facilitate decomposition, garbage was generally grouped into two simple parts; namely organic garbage and inorganic garbage. garbage management was needed to reduce the possibility of positive and negative impacts to the environment. Economic value was grouped into positive impact, while the source of odors and disease clusters were grouped as negative impact. In this study, the focus of the problem is on the negative group. Because if garbage is allowed to pile up in one place in community settlements, it will become a source of unpleasant odors so that it can then become an area for germs to develop. This condition is an indication that the garbage had not been managed properly and could worsen the surrounding environment. Therefore, proceeded from the scientific visual communication design, then at least hazard information and proper garbage processing method needed to be made. Knowledge of garbage separation to reduce environmental pollution would be better if known or understood since childhood. The choice of work form for dissemination of this information was children illustration book. The process of realizing this illustration book work used several stages, the first stage was the process of collecting data about garbage and its processing, then data on the type of book that match the target audience. The second stage was the process of making books, in this stage it went through several processes from pre-production to production.

Las fronteras invisibles de "Magical girl". Narración aleatoria y mitologías incomprendidas en la representación de una identidad nacional
Authors: Del Río Castañeda Laro
Published: March 2021

Las estrategias narrativas que Magical girl (2014) emplea para construir una representación de la españolidad sugieren una manera poco habitual de pensar lo local. El cruce de los cuatro protagonistas se ve mediado por elementos azarosos, irrelevantes o inexplicables. Y el argumento se articula a partir de malentendidos: los personajes se valen de mitologías deformadas, que no les permiten comprender siquiera al otro más cercano. Un estudio que parta de las premisas del materialismo aleatorio de Althusser, la concepción del extranjero de Derrida y los usos de la cultura de De Certeau podrá esbozar las oquedades y las fronteras por las que transitan –inconscientes de estar siendo determinados por ellas– los personajes del filme.

El archivo conocido como Schrank II de la Sächsische Landesbibliothek - Staatsund Universitätsbibliothek Dresden contiene gran parte de la inmensa colección personal de música instrumental que Pisendel se ocupó de reunir durante casi toda su vida.

En el archivo se encuentran los manuscritos para uso personal que contienen las anotaciones de Pisendel para su trabajo diario como intérprete y compositor. Un raro tesoro, ya que este tipo de manuscritos no estaban destinados a ser conservados después de su uso.

De especial interés son los manuscritos de sus propias composiciones. Entre los tachones y enmiendas compositivas encontramos también multitud de anotaciones destinadas a la interpretación, entre las que destacan las que servían para la ornamentación. Estos «manuscritos de trabajo» conviven en ocasiones con copias a limpio, el estudio combinado de estas fuentes arroja una interesante y novedosa visión de las múltiples facetas de Pisendel como compositor e intérprete.

Este legado se hace eco de la práctica interpretativa de su época y nos invita a replantearnos de nuevo consideraciones básicas de la interpretación histórica como el papel del compositor y del intérprete así como a expandir los conceptos de composición, improvisación y ornamentación, dando a esta última un papel fundamental en la elaboración final de la obra musical.

Inzwischen gibt es jedoch auch in vielen anderen Branchen einen Trend zur Miniaturisierung. Extrem klein und leicht sollen die Produkte und Lösungen ausfallen, aber dabei maximal leistungsfähig sein. Das ist jedoch nur dann möglich, wenn sich die verbauten Komponenten ebenfalls „klein machen“. Der Eschweiler Antriebsspezialist Rodriguez hat quer über sein Sortiment hinweg Miniatur-Ausführungen im Programm.

Die Digitalisierung des industriellen Bereichs schreitet in Zeiten von Industrie 4.0 unaufhörlich voran. Gerade im industriellen Umfeld gilt es die Schnittstellen zwischen den einzelnen Systemen optimal aufeinander auszurichten. IO-Link als Sensorschnittstelle schafft hier den ersten Schritt und stellt zusätzlich zu Schaltsignalen auch Diagnose-, Informations- und Parameterdaten eines Sensors bereit. Durch die Kombination von IO-Link und OPC UA in einem Gerät geht Pepperl+Fuchs nun als erster Hersteller auch den zweiten Schritt und schafft die Möglichkeit, diese Daten parallel zur Steuerungskommunikation über OPC UA ganz einfach auch an computer- und cloudbasierte Systeme zu übertragen.

Constraints on vocal production learning in budgerigars (Melopsittacus undulates)
Authors: Osmanski Michael S. , Seki Yoshimasa , Dooling Robert J.
Published: March 2021

Budgerigars (Melopsittacus undulatus) are small Australian parrots with a well-documented, learned vocal repertoire and a high degree of vocal production learning. These birds live in large, social flocks and they vocally interact with each other in a dynamic, reciprocal manner. We assume that budgerigars must process and integrate a wide variety of sensory stimuli when selecting appropriate vocal responses to conspecifics during vocal interactions, but the relative contributions of these different stimuli to that process are next to impossible to tease apart in a natural context. Here we show that budgerigars, under operant control, can learn to respond to specific stimuli with a specific vocal response. Budgerigars were trained to produce contact calls to a combination of auditory and visual cues. Birds learned to produce specific contact calls to stimuli that differed either in location (visual or auditory) or quality (visual). Interestingly, the birds could not learn to associate different vocal responses with different auditory stimuli coming from the same location. Surprisingly, this was so even when the auditory stimuli and the responses were the same (i.e., the bird’s own contact call). These results show that even in a highly controlled operant context, acoustic cues alone were not sufficient to support vocal production learning in budgerigars. From a different perspective, these results highlight the significant role that social interaction likely plays in vocal production learning so elegantly shown by Irene Pepperberg’s work in parrots.
Comparison of Glutues Maximus Activation to Flexion Bias Exercises Along with MET Technique in Subjects with Anterior Rotated Sacroiliac Joint Dysfunction—a Randomised Controlled Trial
Authors: Prem, PT, PHD Venkatesan , Sanika, PT Vaidya , Karvannan, PT, PHD Harikesan
Published: March 2021

Background: Sacroiliac joint dysfunction (SIJD) is the primary source of lowback pain. Main muscles forming the force closure of sacroiliac joint are the biceps femoris and gluteus maximus which increase the stability through massive attachments via sacrotuberous ligament. However, there is a dearth of literature of the importance of activation of gluteus maximus in SIJD. Purpose: To study the effect of gluteus maximus activation on Oswestry Disability Index (ODI), visual analog scale (VAS), and pelvic tilt angle in subjects with anterior rotated sacrolilac joint dysfunction. Settings: The study was conducted in outpatient Physiotherapy Department, Manipal Hospital, Bangalore, India. Participants: Anterior rotated SIJD subjects were recruited in the study. They were divided into two groups (experimental and control groups) by block randomisation. Research Design: This is a randomised control trial. Controlled Treatment: Treatment order was determined by block randomisation. The subjects of both experimental and control group received Muscle Energy Technique (MET) technique on 1st session to correct the anterior rotated SIJD. The experimental group received gluteus maximus activation protocol, whereas the control group received flexion bias exercises. The groups received the treatment of 20 mins per session. There were two supervised sessions per week for four weeks. Main Outcome Measures: The primary outcome measure in the study is Oswestry Disability Index (ODI). The secondary outcome measures included visual analog scale (VAS) and Palpation Meter (PALM). Results: 48 subjects (26 females, 22 males) were randomised into experimental and control groups having anterior rotation SIJD, and average age in groups was 38.83 ± 11.4 years and 34.96 ± 9.5 years, respectively. The within-group analysis showed significant improvements in only ODI outcome of both the groups (p = .001). The between-group analysis in both groups did not show any statistical significant difference in ODI, VAS, or PALM. Conclusion: The flexion bias exercise and the gluteus maximus activation exercises used in this study were equally effective in improving physical function and reduction in pain, and maintaining the normal pelvic angle in subjects with anterior rotated SIJD.
