18F-Choline PET-CT: a potential adjuvant tool for early diagnosis of Osteonecrosis of the Jaw (ONJ) in prostate cancer patients?

Background . Nuclear Medicine imaging techniques, i.e., planar bone scan (Tc99 m scintigraphy) and PET (Positron Emission Tomography) with several tracers, have been sug­gested as useful aids to diagnosis of Osteonecrosis of Jaw (ONJ), that is mostly based on clinical observation (signs and symptoms, with/without bone exposure) and Computed Tomography (CT) scan. Potential advantages of Nuclear Medicine techniques include very early detection of ONJ (due to precocious uptakes), especially in ONJ cases without frank bone exposure. Prostate cancer patients treated with bisphosphonates or denosumab are at risk of ONJ. They undergo bone scan and/or 18F-Choline PET-CT aimed to evaluate response to treatment but attention is generally pointed to extracranial uptakes. Literature data show ability of bone scan to detect maxillary and mandible areas at risk of clinically relevant ONJ, but data are lacking about 18F-Choline PET-CT. Material and Methods . We retrospectively reviewed 18F-Choline PET-CT scans of prostate cancer patients with diagnosis of ascertained ONJ (at CT scan) to search for uptakes in maxillary bones and mandible at time of ONJ diagnosis, or before, or after. Results . Out of 5 prostate cancer patients undergoing 18F-Choline PET-CT scans before or after the ONJ diagnosis time, 4 had clear jaw uptakes at ONJ site next to ONJ diagnosis time or before; one had no uptake (4 years after ONj diagnosis). Conclusions . Our limited experience indicates that 18F-Choline PET-CT scan uptakes, as well as planar bone scan uptakes, are of potential help to early detect ONJ areas, sometimes still in absence of signs and symptoms. Further studies with larger numbers of prostate cancer patients with and without ONJ disease are warranted and should be planned as multicentre trials. The 18F-Choline PET-CT scan uptakes at maxillary bone and mandible should be reported and underlined by Nuclear Medicine specialists, as well as bone scan uptakes, as an aid to oncologists, oral care specialists and patients.
An Active Microchannel Neural Interface with Artifact Reduction

High-density neural electrodes in microchannel interfaces require in-situ amplification of the neural signals and rejection of high-voltage stimulus pulses leaking to the channel in order to adequately detect neural signals in the presence of concurrent stimulation. This paper presents the design of an active microchannel neural interface in 0.18 μm CMOS employing neural recording and stimulation. To reduce stimulus artifacts, a novel method is proposed that disconnects the recording module during concurrent channel stimulation and automatically applies detection and reduction of stimulus artifacts from adjacent channels using a tunable filter. Simulations show that the method provides at least 54 dB artifact attenuation.
Cretaceous to Miocene NW Pacific Plate Kinematic Constraints: Paleomagnetism and Ar–Ar Geochronology in the Mineoka Ophiolite Mélange (Japan)

The Mineoka Ophiolite Mélange is located at the intersection of the Pacific, Philippine Sea, Eurasian, and North American plates. The Mineoka ophiolite origin is disputed, and it has been ascribed to a fully subducted plate or part of the Pacific and Philippine Sea plates. In this paper, we present a kinematic reconstruction of the Mineoka Ophiolite Mélange and its relation with the Pacific Plate, based on new paleomagnetic data and bulk‐rock 40Ar/39Ar ages of basaltic rocks. In addition to standard analyses for paleolatitudes, we performed a Net tectonic rotation analysis on sheeted dolerite dikes to infer the paleospreading direction that formed the ophiolite. The analysis shows that 85–80 Ma MOR pillow basalts erupted at a paleolatitude of N ∼16°, whereas ∼50 Ma basalts formed at N ∼34°. Net Tectonic Rotation analysis suggests that the spreading direction was NE 60°. Ar–Ar ages yielded 53–49 Ma for MORBs and 41–35 Ma for island‐arc basalts. The formation of this ophiolite occurred in the back‐arc spreading of the Nemuro–Olyutorsky arcs of the NW Pacific. It infers that the final consumption of Izanagi below Japan instigated a subduction jump and flipped its polarity. Subduction initiated parallel to the ridge, and a piece of the original back‐arc crust got trapped near the Japan trench during the northwards motion of the Philippine Sea Plate. The contrasting motion between the Pacific and the Philippine Sea plates generated a highly unstable setting followed by a subduction zone that left a small‐sized and short‐lived plate (“Mineoka”), surrounded by subduction zones.
Timeline of Palmer amaranth (Amaranthus palmeri) invasion and eradication in Minnesota

Abstract Palmer amaranth–a fast-growing, challenging-to-control noxious weed that significantly reduces crop yields—was first found in Minnesota in September 2016 in conservation plantings sown with Palmer amaranth contaminated seed mixes. Minnesota Department of Agriculture (MDA) designated Palmer amaranth as a Prohibited Noxious Weed in 2015 and listed it as a Noxious Weed Seed in 2016 by emergency order. A genetic test to identify Palmer amaranth was simultaneously developed by multiple laboratories, providing a tool to limit its spread as a contaminant in seed. Seed companies adopted genetic testing methods for labeling seed for sale, thus reducing introductions via the seed pathway. Additionally, MDA determined that manure spread on crop fields from contaminated screenings fed to livestock resulted in new infestations. Limiting spread via these and other potential pathways was critical to successfully reducing the impact of Palmer amaranth. MDA, University of Minnesota (UMN) Extension, Conservation Corps Minnesota and Iowa (CCMI), farmers, and other partners are working to eradicate these infestations before they can spread. In 2016, 35 sites were sown with Palmer amaranth–contaminated seed mixes. Palmer amaranth was found at eight (23%) of these sites. Management with intensive scouting, torching, prescribed burning, and herbicide application was implemented in 2016 and 2017. By 2018, no Palmer amaranth was found at any of these sites. Similar success to newer infestations in 2018, 2019, and 2020 was achieved using the same methods. MDA recorded management activities and documented a comprehensive timeline of Palmer amaranth in Minnesota. This timeline provides a story of success and challenges in combating and eradicating Palmer amaranth. Nomenclature: Palmer amaranth; Amaranthus palmeri S. Watson
Influencia de la gestión agroganadera y las variables climáticas y topográficas en los cambios de abundancia de la rata topera (Arvicola scherman) en el Oeste del Pirineo

The Fossorial Water Vole (Arvicola scherman) is a species of great interest, both because of its role as prey for a wide variety of predators, and the damages on agriculture. The variation in its population abundance and the factors that modulate it have been widely studied in northern Europe, but they are rather unknown for Pyrenean populations. Here we show the results obtained in the monitoring plan for the species in Navarra from 2016 to 2020, describing both the inter- and intra-annual changes in population abundance, as well as the effect of environmental factors and agricultural management. We found intra-annual variation in its abundance, with significantly higher values in spring than in summer. Interannually, there was a significantly higher abundance both in 2016 and 2020. The accumulated rainfall in the three months prior to sampling and grazing with sheep were the two most important factors that explain variation in population abundance. Both factors had a positive effect on the Fossorial Water Vole, so that its abundance increased with wetter months before sampling and in areas where sheep were present. The role of these factors and other variables of landscape and agricultural management in the changes of abundance of this rodent are also discussed.

Extra-articular distal tibia fibula fracture managed with single posterolateral approach: a case report

Extra-articular distal tibia fractures involve distal tibia approximately 4 cm within tibia plafond with no articular extension. The proper preoperative care, planning and selection of surgical approach is very essential to prevent postoperative wound-related complications. We present a case of a 29 year female patient, presented with left ankle pain and swelling with a wound over the medial aspect of the ankle. X-ray of the left ankle showed extra-articular distal tibia fibula fracture with no neurovascular deficit. We managed both the fractures with open reduction and internal fixation using a single posterolateral approach. At present 1 year follow-up, the patient is having a good range of ankle motion with radiological union with no implant failure and wound-related complications. Extra-articular distal tibia fibula fracture fixation using single posterolateral approach is a viable alternative approach to medial or anterolateral approach in cases of medial or anterior soft tissue problems. It helps in getting a better functional outcome, early mobilisation with less wound-related complications.
Biogas Production from Organic Wastes: Integrating Concepts of Circular Economy

Anaerobic digestion is traditionally used for treating organic materials. This allows the valorization of biogas and recycling of nutrients thanks to the land application of digestates. However, although this technology offers a multitude of advantages, it is still far from playing a relevant role in the energy market and from having significant participation in decarbonizing the economy. Biogas can be submitted to upgrading processes to reach methane content close to that of natural gas and therefore be compatible with many of its industrial applications. However, the high installation and operating costs of these treatment plants are the main constraints for the application of this technology in many countries. There is an urgent need of increasing reactor productivity, biogas yields, and operating at greater throughput without compromising digestion stability. Working at organic solid contents greater than 20% and enhancing hydrolysis and biogas yields to allow retention times to be around 15 days would lead to a significant decrease in reactor volume and therefore in initial capital investments. Anaerobic digestion should be considered as one of the key components in a new economy model characterized by an increase in the degree of circularity. The present manuscript reviews the digestion process analyzing the main parameters associated with digestion performance. The novelty of this manuscript is based on the link established between operating reactor conditions, optimizing treatment capacity, and reducing operating costs that would lead to unlocking the potential of biogas to promote bioenergy production, sustainable agronomic practices, and the integration of this technology into the energy grid.
Adaptive neural network command filtered backstepping impedance control for uncertain robotic manipulators with disturbance observer

In this paper, an adaptive neural network command filtered backstepping impedance control method is developed for uncertain robotic manipulators with disturbance observer. First, an adaptive neural network algorithm is used to estimate the uncertain dynamics in the robot system. Second, impedance control is introduced to adjust the force and position relationship in physical human–robot interaction (pHRI). Third, a disturbance observer is employed to estimate the unknown external disturbance in the environment and compensate the control system to improve the safety of pHRI. Then, the command filtered technique can overcome problems of the ‘computational complexity’ and ‘singularity’ of traditional backstepping design. Finally, the simulation results are provided to illustrate the effectiveness of the proposed control method in pHRI.
Nitrogen nutrition characteristics of rice in simulating water stress condition

A solution cultivation experiment,with/without PEG,was conducted under different ration of NH 4+-N and NO 3--N(100/0,75/25,50/50,25/75 and 0/100)to evaluate the effects of mixed nitrogen nutrition on growth and water use efficiency of rice cultivated in simulating water stress condition.The results obtained were as follows.The rice crop could grow better and take up more nitrogen under a mixed provision of ammonium and nitrate than under single provision of either ammonium or nitrate both in normal and simulating water stress solution cultures.The best growth of rice seedling was found in the NH 4+-N/ NO 3--N ratio of 75/25 in normal solution culture while it was in the NH 4+-N/ NO 3--N ratio of 25/75 in simulating water stress solution culture.It seems that simulating water stress increased the uptake of nitrate and decreased that of ammonium by the rice.The highest water use efficiency(WUE)by the rice could be obtained in the NH 4+-N/ NO 3--N ratio of 75/25 in normal solution culture whereas WUE was increased with the increase of percentage of nitrate in total N supply in simulating water stress solution culture.
Factors Affecting Parents Decision to Send Their Children Abroad for Studies: A Case Study of Parents in Ho Chi Minh City

The study aims to identify factors influencing the parents’ decision in Ho Chi Minh City to send their children to study abroad. The study used the exploratory factor analysis method to examine and estimate regression coefficients on sample 243 observations from parents whose children study abroad. Research has identified 6 factors affecting the decision to send a child to study abroad. The paper shows that the parents’ decisions to let their children study abroad are not only based on the parents’ desire but also on the students’ desire. In addition, factors such as the family’s financial capacity, training programs, career prospects, and self-reliance also affect the parents’ decisions to send their children to study abroad. Interestingly, the study found that factors of self-reliance have negative impacts on parents’ decisions to send their children to study abroad. When they realized that their child may have good self-reliance, great success would be obtained regardless of study location. As a result, motivation for the overseas study was no longer found by them. Since then, domestic training programs need to increase opportunities to practice English, the opportunity to practice independence and flexibility in training programs will limit your children to study abroad.

Organic Rankine Cycle Optimization Performance Analysis Based on Super-Heater Pressure: Comparison of Working Fluids

The organic Rankine cycle (ORC) is widely accepted to produce electricity from low-grade thermal heat sources. In fact, it is a developed technology for waste-heat to electricity conversions. In this paper, an ORC made up of super-heater, turbine, regenerator, condenser, pump, economizer and evaporator is considered. An optimization model to obtain the maximum performance of such ORC, depending on the super-heater pressure, is proposed and assessed, in order to find possible new working fluids that are less pollutant with similar behavior to those traditionally used. The different super-heater pressures under analysis lie in between the condenser pressure and 80% of the critical pressure of each working fluid, taking 100 values uniformly distributed. The system and optimization algorithm have been simulated in Matlab with the CoolProp library. Results show that the twelve working fluids can be categorized into four main groups, depending on the saturation pressure at ambient conditions (condenser pressure), observing that the fluids belonging to Group 1, which corresponds with the lower condensing pressure (around 100 kPa), provide the highest thermal efficiency, with values around η=23−25%. Moreover, it is also seen that R123 can be a good candidate to substitute R141B and R11; R114 can replace R236EA and R245FA; and both R1234ZE and R1234YF have similar behavior to R134A.
3D Carbonate Digital Rock Reconstruction Using Progressive Growing GAN

The development of digital rock physics relies on the availability of high‐quality 3D digital rock images, which can be directly obtained with X‐ray micro‐Computed Tomography (μCT). However, X‐ray μCT is hampered by its high expenses, small sample size (several millimeters in diameter) and low resolution (in micron scale). Although Scanning Electron Microscope (SEM) provides higher resolution on larger rock samples, it only images the 2D rock surface structure. Thus, 3D digital rock reconstruction from 2D cross‐section images becomes promising in saving imaging cost for μCT scan and improving image quality by enabling the incorporation of SEM images in 3D digital rock reconstruction. Here, we propose a machine learning method to reconstruct 3D digital rocks from 2D cross‐section images taken at large constant intervals along the axial direction of the rock sample. The key idea is to train a Progressive Growing Generative Adversarial Network (PG‐GAN) to generate high‐quality gray‐scale cross‐section images, and then reconstruct the 3D digital rock by linearly interpolating the inverted latent vectors corresponding to the sparsely scanned images. We apply our method to reconstructing a large‐size high‐resolution 3D image of an Estaillades carbonate rock sample. We demonstrate that both the reconstructed image and the extracted pore network are visually indistinguishable from the ground truth. Overall, our method achieves nine times speedup of the imaging process, and greater than 4,500 times compression of the image data for the Estaillades carbonate rock sample. The PG‐GAN can enlarge the digital rock repository and enable efficient imaging editing in its linear latent space.
A New Type of Optical Fiber Glucose Biosensor With Enzyme Immobilized by Electrospinning

The immobilization of enzymes is always an important factor that limits the development of biosensors. Especially for optical fiber biosensors, it is usually necessary to modify the surface of the optical fiber through complex chemical reactions so that enzymes can be attached to the surface firmly. In this article, we used the enzyme immobilization method of electrospinning on the optical fiber sensor for the first time. The detection of glucose was realized by using electrospinning to fix a layer of crosslinked polyvinyl alcohol nanofibers that encapsulated glucose oxidase on the surface of the side-polished D-shape optical fiber. The experimental results show that the sensitivity of the designed sensor is 1.875dB/(mg/ml) when the glucose concentration range is 0mg/ml~4mg/ml. The electrospinning method of optical fiber enzyme immobilization is very promising and can be used to rapidly develop more other types of optical fiber biosensors.
Tunable multiwavelength optical comb enabled RoF‐OFDM‐PON with wavelength multiplex

We propose a hybrid full duplex passive optical network with fusion of wavelength‐division‐multiplexing and orthogonal frequency‐division multiplexing (WDM‐OFDM) for a radio‐over‐fiber (RoF) system application. The key of the system is a tunable optical frequency comb (OFC) embedded cascading modulators and a parameter mixer. Moreover, 23 frequency components with 0.6 dB flatness generated by the OFC are used as light sources for each WDM channel. We utilize a 7.5 GHz OFDM wired signal and a 12.5 GHz OFDM wireless signal for downstream transmission and 10 Gb/s OOK (on–off keyed) signals for upstream traffic. Using polarization multiplexing technique, we extract a central optical carrier to bear the upstream signal so that no excess optical source is introduced into the ONU. Thus, the intricacy and costs of system are diminished. Moreover, successful transmission has been demonstrated since the bit error rates of the downstream and upstream signals are always under the adopted forward error correction limit. Furthermore, the proposed system can enhance power budget and reduce cost, which has a promising prospect for future wireless communication.

Surfing websites like "My Room" and "Facebook" has become a common occurrence among the younger generation. Nowadays, social networking websites are an important part of people's social, educational, and professional lives. The aim of this study is to create a group communication framework that uses a protected socket browser interface. This architecture was created with a server scripting language, a SQLite database model, and Python web application frameworks in mind.
An improved random forest algorithm and its application to wind pressure prediction

When making regression predictions, the traditional random forest (RF) algorithm can only make predictions within the training set, which can easily lead to overfitting when modeling data have some specific noise. To solve the problem of over‐fitting, an improved RF method is proposed in this paper for wind pressure prediction. With the aim to verify the prediction performance of the improved RF algorithm, this paper predicts the wind pressure coefficients of a high‐rise building model without wind pressure measurement points. The results show that the improved RF can achieve good results in predicting the mean and fluctuating wind pressure coefficients of high‐rise buildings, and its relative error for each measurement point is basically controlled at 5%, which is acceptable in engineering terms. Further applications show that this improved RF can be used for wind pressure distribution prediction in other large‐span building type wind tunnel tests.
