Impact of Narrative Task Complexity and Language on Macrostructure in Bilingual Kindergarten Children
Authors: Lipner Minna , Armon-Lotem Sharon , Fichman Sveta , Walters Joel , Altman Carmit 
Published: February 2024

Purpose:
We investigated the impact of narrative task complexity on macrostructure in both languages of bilingual kindergarten children and the relationship of macrostructure across languages to guide practitioners' choice of assessment tools and aid in interpretation of results.

Method:

Thirty-nine English–Hebrew bilingual kindergarten children (
M
age
= 65 months) retold two narratives in each language: a one-episode story and a three-episode story. Stories were coded for macrostructure using five story grammar (SG) elements: Internal State-Initiating Event, Goal, Attempt, Outcome, and Internal State-Reaction. Linear mixed and generalized linear mixed models were used to analyze scores for total macrostructure, episode, and SG elements; correlations were conducted to examine cross-language relations in macrostructure.

Results:
In general, performance on the single-episode story was significantly better than for the three-episode story: higher percentages of SG elements were produced, with better performance in the home language/English. In addition to Task and Language effects, Age and Episode (Episodes 1/2/3 of the three-episode story vs. one-episode story) emerged as predictors of macrostructure. Performance on the different episodes of the three-episode story varied, with Episode 3 yielding scores similar to those on the one-episode story. Children produced more Attempts and Outcomes than other SG elements. Finally, the total macrostructure scores yielded low to moderate correlations across languages for both one-episode and three-episode stories, but there were no significant cross-task (one-episode/three-episode story) correlations.

Conclusions:
The study illustrates the importance of task complexity in narrative performance. Ideally, assessment should include a variety of tools, which would include narratives varying in complexity. However, time constraints do not always permit this luxury. The findings here may offer more to therapists than to diagnosticians. Narratives should be manipulated for episodic complexity not only in the number of episodes but also with regard to characters, goals, feelings, and reactions to events.

Model predictive control‐based tracking controller for hybrid‐driven underwater legged robot
Authors: Zhang Guangjie , Yan Weisheng , Cui Rongxin , Ma Feiyu 
Published: February 2024

AbstractTo address the tracking problem of the hybrid‐driven underwater legged robot, a control strategy is proposed that decomposes the whole tracking control system into two subsystems: body‐level and actuator‐level. The body‐level subsystem uses a central pattern generator (CPG)‐based controller to plan suitable gaits to meet the required heading and the forward velocity, crucial for accurate tracking in underwater environments. The actuators‐level subsystem employs a cooperative approach between the C‐shaped legs and thrusters of the robot. To execute the intended gait while adhering to actuation constraints and the no‐slip requirement, the torques of the legs are calculated by a model predictive control and feedback compensation (MPCF)‐based controller. Simultaneously, the calculation of the thrusters concerns four aspects to keep the legs attached to the ground and maintain the stable locomotion of the robot. Simulations on the ROS‐Gazebo platform verify the mobility of the robot and demonstrate the effectiveness of the proposed CPG‐MPCF strategy.
Insulated tip/needle-knife endoscopic stricturotomy is safe and effective for treatment of non-traversable anorectal strictures
Authors: Herman Koby , Kiran Ravi P. , Shen Bo 
Published: February 2024

Abstract
Background and study aims The treatment of anorectal strictures
is particularly challenging and historically focused on surgical resection and/or diversion.
There are a number of endoscopic options, but repeat interventions are common. The use of the
needle knife stricturotomy technique as an alternative to surgery in the treatment of a
variety of strictures has been described, but its use for the treatment of severe anorectal
and anopouch strictures has not been studied.
Patients and methods Our Inflammatory Bowel Disease department’s
records were queried to identify patients with endoscopic non-traversable anorectal/anopouch
strictures. Consecutive patients that underwent insulated tip/needle-knife endoscopic
stricturotomy treatment were included. Primary outcome was immediate traversability of the
treated stricture by the endoscope. Other outcomes included need for reintervention, 30-day
post-procedure events, and follow-up period events.
Results All strictures were immediately successfully traversed
following endoscopic stricturotomy treatment. The mean time to endoscopic reintervention was
5.3 months, with the majority of these patients undergoing repeat stricturotomy. Over a mean
follow-up period of 12.8 months, two patients (8%) required surgical intervention (resection
with coloanal anastomosis with a colostomy and complete proctectomy) for refractory stricture
disease following initial endoscopic stricturotomy. Seven patients (29%) in our study have not
required any further reintervention throughout the study period. There were no 30-day
post-procedure adverse events and no adverse post-procedure events.
Conclusions Endoscopic stricturotomy is safe and effective in
treating severe anorectal/anopouch strictures.
Nation branding as a tool to attract foreign direct investments: a case study of Qatar
Authors: Mohib Aymen A. , Carroll Conor 
Published: February 2024

AbstractNation branding plays a critical role in attracting foreign businesses and, by extension, sustaining countries’ economic development and global competitiveness. Using Qatar as a lens for investigation, this research applied the single, embedded case study method. Purposive sampling with key decision makers in Qatar-based foreign companies representing diverse geographies and industries were used to understand the influence of nation branding on their investment location decision. The findings revealed five key thematic features of Qatar’s nation brand as an investment destination: socioeconomic prosperity, integrated global hub, activist engagement, collectivist culture, and high-end lifestyle. These brand characteristics were compared in relation to the Eclectic Paradigm’s locational advantage and the Anholt Ipsos NBI’s dimensions of exports, governance, culture/heritage, people, tourism, and investment/immigration. The dimensions exerted a strong effect on Qatar’s nation brand and varying levels of influence on FDI attraction. This research contributes to the nexus between nation branding and the FDI literature. Importantly, the results of the study provide useful guidance to government officials, policymakers, and public and private agencies involved in investment promotion. The findings will also prove relevant to foreign investors with regard to their international expansion and location choice.
Low-temperature Raman studies of graphene oxide: Analysis of structural properties
Authors: Glamazda A. , Linnik A. , Lytvyn O. , Karachevtsev V. 
Published: February 2024

This work is devoted to the low-temperature Raman studies of a bright representative of 2D materials—graphene oxide (GO) film in the range of 5–325 K. The performed analysis of the temperature evolution of the peak positions as well as linewidths of two Raman modes D (∼1300 cm−1) and G (∼1600 cm−1) was described in terms of the anharmonic model. The temperature behavior of the G mode demonstrated a slight deviation from the anharmonic model below ∼50 K in contrast to the D mode, which could be explained by involving an additional phonon decay channel. The analysis of the linewidth of the Raman modes showed that the distribution of defects in GO is inhomogeneous and surface functionalization effectively separates neighboring layers. The average value of the distance between defects and the defect density was estimated. The obtained results can be useful for understanding phonon dynamics for the development of nanodevices based on 2D materials where confinement of propagation of phonon excitations plays a key role.

Published: February 2024

In order to obtain a fibrous biofilm carrier material with a good water purification effect, the biofilm carrier of PAN and PAN-PEO (mass ratio 9:1) was prepared by the electrospinning process, and the performance differences between the fabric biofilm carriers of PAN, PAN-PEO (mass ratio 9:1), and blank non-woven fabric, including the structure of biofilm carriers (surface morphology, specific surface area, and porosity), surface wettability (water contact angle and water absorbance) and membrane hanging ratio, were tested through various characterization methods. The experimental results show that the nanofiber membrane of PAN and PAN-PEO (mass ratio 9:1) prepared by the electrospinning process has a diameter of 75–375 nm, a specific surface area of 19.2 m2/g, and a porosity of 80%. The fiber diameter of non-woven fabric is in the micrometer range, with a specific surface area of 0.3659 m2/g and a porosity of 60%. This indicates that the nanofiber biofilm of PAN and PAN-PEO (mass ratio 9:1) prepared by electrospinning belongs to the carrier with a small diameter, high specific surface area, and high porosity, which can provide more attachment sites and pores for micro-organisms and is more conducive to their attachment in wastewater treatment. At the same time, the water contact angles of PAN and PAN-PEO (mass ratio 9:1) are 27.97° and 18°, respectively, and the water absorption of both reached 300%. The water contact angle of non-woven fabric is 93.32°, and the water absorption rate is only 75%. This shows that the nanofiber biofilms of PAN and PAN-PEO (mass ratio 9:1) prepared by electrospinning effectively improve the infiltration of the carrier in sewage. Finally, under the same conditions, bacterial growth and biofilm growth experiments were conducted on the nanofiber biofilm carriers of PAN and PAN-PEO (mass ratio 9:1) and the biofilm carriers of non-woven fabric. It was found that the effectiveness of the PAN and PAN-PEO (mass ratio 9:1) nanofiber biofilm carrier was significantly higher than that of non-woven fabric in treating wastewater. After 3 days of bacterial cultivation, the membrane hanging ratio of the PAN nanofiber biofilm carrier was 90.36%, the membrane hanging ratio of the PAN-PEO (mass ratio 9:1) nanofiber biofilm carrier was 82.04%, and the membrane hanging ratio of the non-woven fabric biofilm carrier was only 27.32%. After 15 days of bacterial cultivation, the membrane hanging ratio of the PAN nanofiber biofilm carrier was 147.52%, the membrane hanging ratio of the PAN-PEO (mass ratio 9:1) nanofiber biofilm carrier was 147.52%, and the membrane hanging ratio of the non-woven fabric biofilm carrier was 110.53%.

Published: February 2024

Pyrotechnic device is the key initiating component of weapon system, and its function reliability will directly affect the triggering of detonation and actuation mechanism. In order to enhance the survival ability of pyrotechnic device in intricate electromagnetic interference environment, it is necessary to carry out in-depth research on the electromagnetic protection technique of pyrotechnic device. In this paper, a new electromagnetic protection circuit based on vertical punch through PN junction device is proposed, which monolithically integrates the circuit with polysilicon semiconductor bridge on a single chip. The Electro-static Discharge (ESD) test was carried out according to the method specified by standard electrostatic standard 500 pF/500 Ω/25 kV, and the ESD capability of the proposed new chip was not less than 25 kV. Compared with the electromagnetic protection circuit by transient voltage suppressor diode based on lateral punch through junction device structure, the new chip increases the effective junction area of PN junction, reduces the current density, and increases the current conduction ability and electrostatic roughness of the diode. The new chip has a larger diode effective junction capacitance, which not only improves the ESD capability but also improves the RF protection capability at the same time.

Abstract

Objective. Retinal prosthetics offer partial restoration of sight to patients blinded by retinal degenerative diseases through electrical stimulation of the remaining neurons. Decreasing the pixel size enables increasing prosthetic visual acuity, as demonstrated in animal models of retinal degeneration. However, scaling down the size of planar pixels is limited by the reduced penetration depth of the electric field in tissue. We investigated 3-dimensional (3d) structures on top of photovoltaic arrays for enhanced penetration of the electric field, permitting higher resolution implants. Approach. 3D COMSOL models of subretinal photovoltaic arrays were developed to accurately quantify the electrodynamics during stimulation and verified through comparison to flat photovoltaic arrays. Models were applied to optimize the design of 3D electrode structures (pillars and honeycombs). Return electrodes on honeycomb walls vertically align the electric field with bipolar cells for optimal stimulation. Pillars elevate the active electrode, thus improving proximity to target neurons. The optimized 3D structures were electroplated onto existing flat subretinal prostheses. Main results. Simulations demonstrate that despite exposed conductive sidewalls, charge mostly flows via high-capacitance sputtered iridium oxide films topping the 3D structures. The 24 μm height of honeycomb structures was optimized for integration with the inner nuclear layer cells in the rat retina, whilst 35 μm tall pillars were optimized for penetrating the debris layer in human patients. Implantation of released 3D arrays demonstrates mechanical robustness, with histology demonstrating successful integration of 3D structures with the rat retina in-vivo. Significance. Electroplated 3D honeycomb structures produce vertically oriented electric fields, providing low stimulation thresholds, high spatial resolution, and high contrast for pixel sizes down to 20 μm. Pillar electrodes offer an alternative for extending past the debris layer. Electroplating of 3D structures is compatible with the fabrication process of flat photovoltaic arrays, enabling much more efficient retinal stimulation.

Abstract
Metal-organic frameworks (MOFs) are produced by the reaction of metal ions and organic linkers with extremely crystalline and porous coordination networks. The applications of MOF cover from gas purification, gas separation, catalysis and super-capacitors. This work reports on the synthesization of metal-organic framework (MOF), using mangan (II) nitrate tetrahydrate as source of metal ions, 2-methylimidazole as organic ligand and ethanol as solvent. The material was prepared using precipitation method, at room temperature for 48 hours. The characterization of this material were carried out including X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The SEM analysis shows an irregular structure with a few petals. XRD shows several peaks, indicating crystallinity of the material, and amorphous state. To study the electrochemical property of the material, Cyclic Voltammetry (CV) was conducted. The cyclic voltammetry result shows peak at 0.23 V, with current output of 0.14 μA, with no changes in peak position as the scanning rate increases from 10 to 100 mV/s.

Published: February 2024

Abstract
In this study, nickel cobalt phosphate ((Ni,Co)(PO4)3) has been developed as a positive electrode in supercapacitors. (Ni,Co)(PO4)3 is synthesized through a phosphorization and carbonization method using NiCo glycerate as a precursor combined with triethyl phosphate (TEP), subsequently an annealing process at 600°C under air conditions. The choice of solvent like hexanol has a significant influences on the morphology of nickel cobalt phosphate ((Ni,Co)(PO4)3), leading to the formation of cracker-like structures. Additionally, the resulting product exhibits an amorphous phase, indicating the absence of a well-defined crystalline arrangement. The electrochemical performance evaluation shows the peak from oxidation and reduction reactions at scan rate 5 mVs−1 until 100 mVs−1. Following that the specific capacitance reaches 743 Fg−1 at current density 1 Ag−1.

Published: February 2024

Abstract
Carbon monoxide (CO) gas detection using a modified WO3-based sensor is being developed. The solvent for solvothermal use, a combination of 2-Propanol and 2-Methoxyethanol, was employed as a capping agent before graphene was used as a component of nanocomposites. Following the creation of the powder, it is combined with ethyl glycol and applied to an alumina substrate using the Doctor Blade process.
By X-ray diffraction research, it was discovered that the solvent combinations of 2-Propanol and 2-Methoxyethanol formed monoclinic WO3 in the amounts of 40-0 and 30-10, respectively, while the solvent combinations of 20-20 are thought to have produced W18O49 and 10-30, WO2.9, respectively. According to the SEM examination, the WO3 generated was first present as nanowires and nanorods before being calcined at 500 degrees Celsius, and it then appeared as nanoparticles. The sensor may work at a low temperature of 150°C, and the best sensitivity is found when the sensor is used at a temperature of 250°C, according to the CO gas test findings.

Abstract
Microwave imaging is a straightforward approach to detect scattering in a detected object. One application of microwave imaging is breast cancer detection, the most prevalent type of cancer in Indonesia and the leading cause of cancer-related deaths. The planar monopole antenna offers several advantages, including low bandwidth compared to microstrip antennas and a simple structure for easy and affordable fabrication. Metamaterial can be added to the antenna to operate within the ultra-wideband frequency range of 3,1-10,6 GHz. Metamaterial expands the bandwidth and offers advantages such as low fabrication costs and miniaturization potential. This study aims to design a planar monopole antenna with a hexagonal patch using metamaterial. The simulation results show a working frequency range of 3,0699 - 20,779 GHz, while the realized results are 2,6 - 11,3 GHz and 15,2 - 17 GHz. The simulated bandwidth value is 17,7091 GHz, whereas the realized bandwidth values are 8,7 GHz and 1,8 GHz. The return loss values are ≤ 10 dB and the VSWR values are ≤ 2. The gain at the frequency of 7,038 GHz is 1,963 dBi in simulation and 1,698 dBi in realization. Additionally, changes in electromagnetic parameters are observed when the antenna detects cancer.
Potential impact of wintertime Arctic forcing on the subsequent sea surface temperature anomalies in the tropical eastern Pacific
Authors: Guo Yuanyuan , Chen Xiaodan 
Published: February 2024

Abstract
Despite extratropical forcing being recognized as an important factor that can modulate El Niño-Southern oscillation (ENSO) properties on the interannual time scale, little is known about whether and how Arctic forcing changes the tropical sea surface temperature (SST). This current study reveals a significant link between the net surface sensible heat flux (SHF) in the Arctic and the SST anomalies in the tropical eastern Pacific (TEP). Specifically, anomalous upward SHF into the Arctic atmosphere in February leads to a warmer TEP in the subsequent spring and summer. A northeast-southwest-tilted North Pacific Oscillation-like atmospheric pattern associated with the upward Arctic SHF anomaly induces SST cooling in the subtropical North Pacific via positive Wind-Evaporation-SST feedback, which further promotes TEP SST warming via meridional heat advection, thermocline feedback, and nonlinear processes. The spring-to-summer TEP SST anomalies driven by the preceding anomalous Arctic SHF can potentially modulate the seasonal evolution of ENSO. Our findings imply that we should take into account the Arctic-tropics linkages when comprehensively understanding the ENSO variability and improving ENSO projection skills.
