Reconstruction of extensive sequel of frontal fracture: optimizing results

Introduction: Fractures of the frontal bone correspond to 5 to 15% of all facial fractures. This type of fracture can lead to difficulties in restoring bone congruence and to postoperative secondary aesthetic problems. Objective: This paper aims to present a clinical case report of frontal bone fracture where a late reconstruction was performed using a titanium mesh with the aid of stereolithographic model prototyping. Case report: Female patient, 26 years old, with aesthetic sequelae in the upper third of the face after a motorcycle accident. The imaging exams showed a comminuted frontal bone fracture, as well as upper edge and right orbit ceiling involvement. The planning consisted of reconstruction of the affected area with the use of a titanium mesh pre-shaped in a stereolithographic model. The procedure was performed under general anesthesia and coronal access. After installation of the fixation material, pericranial flap rotation and suture of the surgical wound were performed. The patient progressed well, with considerable improvement in facial aesthetics. Conclusion: This paper reports the importance of good planning in cases of frontal bone fracture sequel, in which the use of model-shaped mesh in a stereolithographic model tends to optimize surgery, bringing aesthetic and psychosocial benefits.

Strain-Promoted Azide–Alkyne Cycloaddition-Based PSMA-Targeting Ligands for Multimodal Intraoperative Tumor Detection of Prostate Cancer

Strain-promoted azide–alkyne cycloaddition (SPAAC) is a straightforward and multipurpose conjugation strategy. The use of SPAAC to link different functional elements to prostate-specific membrane antigen (PSMA) ligands would facilitate the development of a modular platform for PSMA-targeted imaging and therapy of prostate cancer (PCa). As a first proof of concept for the SPAAC chemistry platform, we synthesized and characterized four dual-labeled PSMA ligands for intraoperative radiodetection and fluorescence imaging of PCa. Ligands were synthesized using solid-phase chemistry and contained a chelator for 111In or 99mTc labeling. The fluorophore IRDye800CW was conjugated using SPAAC chemistry or conventional N-hydroxysuccinimide (NHS)–ester coupling. Log D values were measured and PSMA specificity of these ligands was determined in LS174T-PSMA cells. Tumor targeting was evaluated in BALB/c nude mice with subcutaneous LS174T-PSMA and LS174T wild-type tumors using μSPECT/CT imaging, fluorescence imaging, and biodistribution studies. SPAAC chemistry increased the lipophilicity of the ligands (log D range: −2.4 to −4.4). In vivo, SPAAC chemistry ligands showed high and specific accumulation in s.c. LS174T-PSMA tumors up to 24 h after injection, enabling clear visualization using μSPECT/CT and fluorescence imaging. Overall, no significant differences between the SPAAC chemistry ligands and their NHS-based counterparts were found (2 h p.i., p > 0.05), while 111In-labeled ligands outperformed the 99mTc ligands. Here, we demonstrate that our newly developed SPAAC-based PSMA ligands show high PSMA-specific tumor targeting. The use of click chemistry in PSMA ligand development opens up the opportunity for fast, efficient, and versatile conjugations of multiple imaging moieties and/or drugs.
Micromechanical bulk acoustic wave resonator

We describe the use of bulk acoustic mode in micromechanical silicon resonators operating at radio frequencies. Based on measured data from the fabricated resonator (f/sub r//spl sim/14 MHz, Q>100 000) we analyze the characteristic impedance and signal levels in such microdevices and compare the values with conventional quartz crystals. We find that the high impedance level of microresonators can be met with integration of the readout electronics and that silicon can accommodate significantly larger vibration energy densities than quartz. Based on the results, we anticipate a wide application range for the micromechanical bulk acoustic wave structures in future wireless communication devices and microsensors.

A free-drifting buoy has been designed which incorporates an array of capacitance wave gauges, an anemometer , compass, and a vertical accelerometer. The buoy is intended to drift free of the influence of an attending ship and collect and log high frequency wave data for verification of radar remotely sensed imagery. Data collected is used to derive energy directional wave spectra for wavelengths between 10 and 100 cm and wave slope statistics for wave scales larger than 10
Microstrip antenna array with series-fed 'through-element' coupled patches

A new microstrip antenna array with series-fed patches is proposed. To reduce the length of feeding lines the `through-element' feeding technique has been developed. A microstrip patch in which the input feeding line is directly connected and the output line is coupled to a patch is investigated. By adjusting the length of the coupling region an appropriate coupling level is achieved. A 4 × 1 antenna array operating within the 24 GHz frequency band for radar sensor applications is designed using the proposed feeding technique
Real-time monitoring of the prototype design of electric system by the ubidots platform

In this paper, a prototype DC electric system was practically designed. The idea of the proposed system was derived from the microgrid concept. The system contained two houses each have a DC generator and load that consists of four 12V DC lamps. Each house is controlled fully by Arduino UNO microcontroller to work in Island mode or connected it with the second house or main electric network. House operating mode depends on the power generated by its source and the availability of the main network. Under all operating cases, the minimum price of electricity consumption should satisfy as possible. Information between the houses about the operating mode and the main network state was exchanging wirelessly with the help of the RF-HC12. This information uploaded to the Ubidots platform by the Wi-Fi-ESP8266 included in the Node MCU microcontroller. This platform has several advantages such as capture, visualization, analysis, and management of data. The system was examined for different cases to verify its working by varying the load in each building. All tested states showed that the houses transfer from one mode to another automatically with high reliability and minimum energy cost. The information about the main grid states and the sources of the houses were monitored and stored at the Ubidots platform.
Evolution of synapses and neurotransmitter systems: The divide-and-conquer model for early neural cell-type evolution

Nervous systems evolved around 560 million years ago to coordinate and empower animal bodies. Ctenophores - one of the earliest-branching lineages - are thought to share a few neuronal genes with bilaterians and may have evolved neurons convergently. Here we review our current understanding of the evolution of neuronal molecules in nonbilaterians. We also reanalyse single-cell sequencing data in light of new cell-cluster identities from a ctenophore and uncover evidence supporting the homology of one ctenophore neuron-type with neurons in Bilateria. The specific coexpression of the presynaptic proteins Unc13 and RIM with voltage-gated channels, neuropeptides and homeobox genes pinpoint a spiking sensory-peptidergic cell in the ctenophore mouth. Similar Unc13-RIM neurons may have been present in the first eumetazoans to rise to dominance only in stem Bilateria. We hypothesise that the Unc13-RIM lineage ancestrally innervated the mouth and conquered other parts of the body with the rise of macrophagy and predation during the Cambrian explosion.

Behaviour of post-tensioned concrete box girders

This paper describes the results obtained to date from a study of the strains developed in two post-tensioned, prestressed concrete box girder bridges both during their construction and subsequent service lives. The instrumentation that was used is described and the simplification and representation of the material properties that were required for the subsequent analysis of the data are discussed. Results are presented for both short-term shrinkage strains developed during the construction of the concrete segments, short-term creep strains developed during the construction of the viaducts and long-term creep and service life strains developed over the 17-year period since their construction. It is shown that the assumptions, which are generally accepted for the design of such superstructures, are valid and that satisfactory predictions of the long-term behaviour can be obtained from analyses based on short-term properties, despite the variable environmental conditions that are likely to be experienced by.
Violin Portamento: An analysis of its use by master violinists in selected nineteenth-century concerti

Portamento [shifting technique] is regarded as one of the most difficult and intricate aspects of violin playing. Given that each performer’s decision to select a particular portamento is based on his/her musical interpretation, the use of portamento is very individualistic in nature. No pedagogical sources are available for students and teachers to generate critical thinking about when, why, and how violinists might employ portamento. The decision making process regarding its use remains intuitive and amorphous. In this study, portamento styles were examined in real performances by master violinists, Heifetz, Huberman, Kreisler, Mutter, D. Oistrakh, Perlman, Shaham, and Vengerov. Target Intervals (TIs) in which portamenti were employed were extracted with computer software from the first movement of Brahms, Lalo, Mendelssohn, and Tchaikovsky concerti. The selected TIs were analyzed, considering musical factors and individual characteristics of performers. Computer software programs generated visual images of portamento execution, these spectrographs, displayed the progression of pitch change and intensity over time as well as patterns and type of portamento. Results showed that the performers tended to agree more on the type of portamento in descending intervals. B-portamento, occasionally called the French slide, and L-portamento, known as

Characterisation of Plant Growth-Promoting Endophytic Bacteria from Sugarcane and Their Antagonistic Activity against Fusarium moniliforme

The use of endophytic bacteria in agriculture provides an effective way of improving crop yield and significantly reducing chemical usage, such as fungicides. This research was conducted to explore endophytic bacteria with plant growth promotion (PGP) and antifungal activities against Fusarium moniliforme AIT01. In this study, we obtained 52 isolates of endophytic bacteria associated with the roots and stems of sugarcane from Nakhon Ratchasima province, Thailand. In vitro antagonistic activity test showed that 14 out of 52 isolates had antagonistic activity against the fungal pathogen F. moniliforme AIT01. These antagonistic endophytic bacteria were identified as belonging to six different species as follows: Nguyenibacter vanlangensis, Acidomonas methanolica, Asaia bogorensis, Tanticharoenia aidae, Burkholderia gladioli and Bacillus altitudinis based on phenotypic characteristics, along with phylogenetic analysis of their 16S rRNA gene sequences. Seven isolates effectively inhibited F. moniliforme AIT01 mycelial growth by up to 40%. The volatile compounds of six isolates reduced the growth of F. moniliforme AIT01 by over 23%. Moreover, riceberry rice seedlings previously treated with B. gladioli CP28 were found to strongly reduce infection with phytopathogen by 80% in comparison to the non-treated control. Furthermore, the isolates also showed relevant PGP features, including ammonia production, zinc and phosphate solubilisation, auxin and siderophore biosynthesis. These results demonstrated that the tested endophytic bacteria could be successfully utilised as a source of PGP and biocontrol agent to manage diseases caused by F. moniliforme.
Complete analysis and comparative study of digital modulation techniques for dual three-phase AC motor drives

The main goal of the paper is to perform a complete analysis and a comparative study of different digital pulsewidth modulation (PWM) techniques for dual three-phase induction machine drives. Six different digital PWM strategies are considered: four of them are present in the literature, the other two have been introduced by the authors in this paper. The comparison between the modulation strategies is based on several criteria: current harmonic minimisation, hardware and software implementation complexity with low cost fixed-point DSP platforms. Simulation results are provided to emphasize the advantages and disadvantages of each method. Experimental tests have been carried out to validate the most promising strategy which gives satisfactory results in terms of current harmonic minimisation and low implementation complexity.
Airport Gate Reassignments Considering Deterministic and Stochastic Flight Departure/Arrival Times

This article, from a special issue on the modeling and optimization of transportation systems, reports on a study undertaken to develop a gate reassignment model (GRM) designed to consider both deterministic and stochastic flight departure and arrival times. The authors define deterministic flights as having a certain departure/arrival time; while stochastic flights have a variety of stochastic departure/arrival times. They apply an 0–1 integer programming technique to formulate the GRM. In real-world settings, gate reassignments need to be handled repeatedly, so to make this possible the GRM is applied to a dynamic gate reassignment framework (DGRF). The theoretical effectiveness of the GRM applied to the DGRF is evaluated by the development of a lower bound solution. They also report on several sensitivity analyses, including for the number of scenarios and the disturbance time, that were conducted to gain a better understanding of the influence of different parameters on the solution. The authors determine that, based on numerical tests related to the operations of an international Taiwan airport, the proposed GRM and DGRF perform well.
AN ANALYSIS OF BASKETBALL PLAYERS' MOVEMENTS IN THE SLOVENIAN BASKETBALL LEAGUE PLAY-OFFS USING THE SAGIT TRACKING SYSTEM

The main aim of the paper was to present the SAGIT measuring system and to establish the covered distance and the average velocity of basketball players' movements by using the aforementioned system. The SAGIT system is a relatively new technology which is based on computer-vision methods and enables an automated acquisition of data from the video recordings of games. The system was used to track the movements of 23 basketball players from two teams during three games of the play- offs of the Slovenian National Championship for men. It was established that during the 40 minutes of the active phase of the game the players covered a distance of 4,404 m on average and that during the passive phase, they covered an additional 1,831 meters. The players' average velocity of movement during the active phase of the game was 1.86 m/s. Although the players from one of the teams moved slightly faster and covered a greater distance, the differences between the teams in terms of the average velocity and covered distance were not statistically significant.
Coralline Hydroxyapatite Coated with a Layer Biomimetic Calcium Phosphate Containing BMP-2 Induces Dose-Related Ectopic Bone Formation in Wistar Rats

In order to evaluate loading methods and the dose dependency of bone morphogenetic protein 2 (BMP-2) in ectopic bone formation, an osteoinductive material consisting of commercially available coralline hydroxyapatite (CHA) was coated with a layer of biomimetic calcium phosphate (BioCaP) containing BMP-2 in different ways. Eight groups—each containing samples of 0.25 g CHA—were formed and coated with, respectively, BioCaP with internally incorporated BMP-2 in concentrations of 1, 5, 10, 20, 40 and 60 µg per sample, and the two control groups with BioCaP only and BioCaP with 20 µg of adsorbed BMP-2 per sample. The samples were implanted subcutaneously in 27 male Wistar rats. The histological results show that there is no bone formation in the group in which no BMP-2 was included. All samples with BioCaP containing BMP-2 show bone formation. The group with 20 µg of adsorbed BMP-2 per sample shows the least bone formation. Coating-incorporated BMP-2 is more efficient in inducing bone formation than adsorbed BMP-2. The group with 5 µg of coating-incorporated BMP-2 per sample shows the most bone formation. Increasing the amount of coating-incorporated BMP-2 up to 60 µg does not improve ectopic bone formation.
Phosphorus removal in a vertical flow constructed wetland using dolomite powder and chippings as filter media

Different kinds of natural and artificial filter media are able to retain phosphorus in the constructed wetlands. Due to the fact that the constructed wetland needs huge amounts of the filter media, it is very important to find locally available material which distinguishes itself by its ability to retain phosphorus. The materials found in Lithuania were considered and dolomite was chosen. Two dolomite fractions, dolomite powder (1–2 mm) and dolomite chippings (2–5 mm), and sand media were used in the laboratory- scale installed for the comparative experiments. The laboratory-scale with dolomite as the filter media was on average by 21% more efficient in total phosphorus removal in comparison with the sand media. Based on the laboratory research pilot–scale vertical flow constructed wetland of 160 m 2 was installed and planted with reed Phragmites australis . The dolomite chippings as filter media were chosen in order to avoid the danger of the clogging of constructed wetland. Efficiency of total phosphorus removal in the pilot-scale vertical flow constructed wetland was on average 95.7%, phosphates removal – 94.8% within one year.
CMOS readout circuit design for infrared image sensors

The infrared imaging system has been developed for more than 50 years, from the early stage the scanned imaging system using single unit detector to imaging system using focal plane detector arrays. For focal plane array detectors, the readout circuit is used to read the photon detector signal out. Charge coupled device had been used for the readout of the focal plane array detectors and currently CMOS technology is used. In this paper, readout circuit design using CMOS technology for infrared focal plane array detectors is reviewed. As an interface between the detector and the image signal processing circuits, readout circuit is a critical component in the infrared imaging system. With the development of the CMOS technology, the readout circuit is now moving into the CMOS technology. With the feature size scaling down, the readout cell size is reduced, which enable us to integrate more complex circuits into the readout cell. From the system point of view, different requirements and specifications for the CMOS readout circuit are analyzed and discussed. Different readout circuit parameters such as injection efficiency, dynamic range, noise, detector biasing control, power consumption, unit cell area, etc are discussed in details. Performance specifications of different readout cell structures are summarized and compared. Based on the current mirroring integration readout cell, a fully differential readout cell is proposed. The injection efficiency of this proposed readout cell is very close to unity and the detector biasing voltage is close to zero. Moreover, the dynamic range of the proposed readout cell is increased and the rejection on interference is improved because of the fully differential structure. All these are achieved without much power consumption increasing. Finally, a full digital readout circuit concept is introduced. By employing a current controlled oscillator, the photocurrent is converted to frequency and integrated in digital domain and the final output is digital signal.
Solution-Responsive Particle Size Adaptivity in Lagrangian Vortex Particle Methods

In order to minimize the computational resources necessary for a given level of accuracy in a Lagrangian Vortex Particle Method, a novel particle core size adaptivity scheme has been created. The method adapts locally to the solution while preventing large particle size gradients, and optionally adapts globally to focus effort on important regions. It is implemented in the diffusion solver, which uses the Vorticity Redistribution Method, by allowing and accounting for variations in the core radius of participating particles. We demonstrate the effectiveness of this new method on the diffusion of a δ-function and impulsively started flow over a circular cylinder at Re = 9,500. In each case, the adaptive method provides solutions with marginal loss of accuracy but with substantially fewer computational elements.
