Published: October 2021

AbstractPediatric patients identified at increased risk for headache due to ocular refractive errors were evaluated to produce a diagnostic tool called the HAMS score that will help establish the likelihood of headache due to refractive errors.Methods Data on the ocular diagnosis and headache complaints of 726 pediatric patients of both sexes were obtained from the medical records of an ophthalmological service in Brazil (Hospital de Olhos Santa Luzia). Age, use of glasses, and ocular diagnosis were also considered to create an index based on the number of ocular diagnoses in a given individual (HAMS score) to verify their association with the incidence of headache. Once the database was finalized, it was then analyzed to identify the variables capable of predicting the occurrence of headaches, following which a profile of those at the highest risk was produced by comparison.Results Only the ocular diagnosis was significantly associated with headache as a function of sex, age, use of glasses, farsightedness, astigmatism, myopia, and strabismus, indicating the relative impact of each ocular diagnosis on the probability of headache. According to the HAMS score, strabismus is more likely to have headache (5.21), followed by hyperopia (3.10), myopia (2.67), and, finally, astigmatism (1.86). The findings showed that the presence or absence of refraction errors and strabismus is predictive of the occurrence of headache, particularly in a small group of patients (6.2%) where the probability of headache was 57.8%. Such patients were characterized by being younger, having a combination of strabismus, hyperopia, and astigmatism, and already be using corrective lenses.Conclusion The index based on the most common ocular diagnoses (HAMS score) is effective, and it has practical application in identifying children and adolescent patients with a greater or lesser propensity for headaches of ophthalmic origin.
Cognitive Radio Networks Based on Users' Reputation Scheme
Authors: Ammar Mahmoud A. , Rehan Salahedin A. 
Published: October 2021

Cognitive Radio (CR) can be defined as a technology that allows users to change the transmission parameters as required to increase the spectrum efficiency. Because of this mechanism, some threats emerge. Two major threats are found in CR. The first is the Primary User Emulation Attack (PUEA), where the attacker is able to transmit at a forbidden time slot effectively, emulating the signals of the primary user. This makes all the system users believe that the spectrum is occupied by a good primary user. The second threat is known as the spectrum sensing data falsification attack (SSDF). In this case, the attackers send false observation information, intentionally or unintentionally, to the fusion center (FC), causing it to make the wrong decision. In this study, the scheme presented was based on a users' reputation for secure spectrum access in cognitive radio networks. Each Secondary User (SU) performs local sensing and then forwards the sensing results to the main fusion center FC. The FC makes the final decision about the presence of the primary user based on the proposed approach. The schemes substantially reduce the effect of cognitive users with low reputation values while improving the impact of cognitive users with the high reputation values on the final decision. It has been verified that the proposed approach can improve the sensing performance under the impact of a different number of reliable and unreliable users in a CR network. Results based on simulation show that the proposed scheme outperforms the traditional majority scheme despite a high number of malicious users.
Effect of pH, Sucrose Concentrations and Medium States on in vitro Root-ing of Pineapple (Ananas comosus (L) Merr) cv Queen
Authors: Hamad Abdelhamid M. 
Published: October 2021

The effect of medium states (liquid, semi solid, solid), pH (5.0, 5.5, 6.0, 6.5) and sucrose concentrations (10, 20, 30, 40 g/l) on in vitro rooting of pineapple cultured in full strength MS enriched with IBA at 0.5 mg/l were investigated. According to average overall sucrose concentrations, overall pH adjustments, and at each combination of equal sucrose and pH, liquid medium was always super than solid and semisolid. The tallest plantlets (66 to 71 mm) obtained in liquid medium enriched with sucrose at 10 and 20 g/l both adjusted to pH 6.0; sucrose at 20 g/l and adjusted to pH 6.5 and sucrose at 30 g/l and adjusted to pH 5.0. All of the above combinations except sucrose at 20 and pH 6.0 resulted in 100% rooting. Sucrose at 30 g/l and pH 5.0 resulted in two times more (11 roots per shoot) and three times longer roots (39 mm) than the other treatments (5 roots each about 14 mm long). Each rooting parameter had different optimum combinations of medium state, sucrose and pH adjustment. For any parameter, proper pH adjustment could reduce the optimal sucrose enrichment from 30 to 20 and even to 10 g/l. Hence, pH adjustment is suggested as an important approach for reduction of in vitro rooting medium cost.
Hyperthermia in Cancer Care: A Literature Review
Authors: Conte Ellen , Psihogios Athanasios , Seely Dugald 
Published: October 2021

Introduction: Hyperthermia (HT) in cancer management refers to the external application of heat to raise intratumoural temperature to between 39°C and 45°C. Locoregional hyperthermia (LRHT) is the most used and studied type of HT in cancer care. A literature search was conducted to produce a monograph to help clinicians and patients make informed choices in considering the application of this therapy.
Methods: A search was performed in Medline and Cochrane library for LRHT and cancer in May 2020. Eligible studies were English-language clinical studies reporting on efficacy, quality of life (QoL), safety, or feasibility. Additional cursory literature scoping was performed to identify missing papers and background information. Papers were independently screened by two reviewers. Following development of a full monograph, a condensed version suitable for publication was created and is presented here.
Results: A total of 980 articles were identified and 166 met inclusion criteria. Most were single-arm or observational. However, among the 166, there were 7 systematic reviews (including 37 RCTs) and 18 additional RCTs identified. Several mechanisms of action have been proposed for HT in cancer care including physiological changes, direct cytotoxic effects, chemosensitization and radiosensitization, and immune modulation. Locoregional HT is used primarily as an adjunct to chemotherapy and radiotherapy due to its possible synergistic effects. Various studies demonstrated improved outcomes for patients treated with LRHT and chemo-and/or-radiotherapy. The best evidence for improved disease control and survival is seen for breast cancer (locally recurrent), cervical cancer, esophageal and gastric cancers, head and neck squamous cell carcinoma, and high-risk soft tissue sarcoma. Research related to quality of life (QoL) is limited and often focuses on pain. Hyperthermia with modern technology and treatment planning is generally well tolerated; the most common side effects are discomfort, mild pain, local erythema, skin burns, and, less commonly, subcutaneous burns. Trial heterogeneity and methodological concerns limit the strength of conclusions.
Conclusions: Locoregional HT is a promising adjunct treatment to chemotherapy and radiotherapy for a variety of cancer types. To determine in what situations this therapy could be best applied, more high-quality well-controlled studies are needed.
High‐Affinity Copper Transporter Ctr1
Authors: Yuan Peng 
Published: October 2021

AbstractCopper serves as an essential cofactor for enzymes involved in a multitude of physiological processes such as mitochondrial respiration, iron metabolism, neuropeptide biogenesis, and connective tissue formation. An appropriate copper content is critical for normal growth and development, and inappropriate Cu levels have been associated with pathological conditions such as neurodegeneration, cancer, and immune disorders. The high‐affinity copper transporter Ctr1 is an evolutionarily conserved copper importer that plays a crucial role in dietary copper uptake and intracellular copper distribution. Additionally, Ctr1 has been implicated in cellular uptake of platinum‐based chemotherapeutic agents. As the primary Cu importer, Ctr1 is a promising therapeutic target of numerous diseases associated with inappropriate Cu levels. Recent advances in structural and mechanistic studies of Ctr1, including electron and X‐ray crystallographic analyses and functional reconstitution, have provided insights into copper transport mechanisms, suggesting novel therapeutic opportunities for the treatment of Cu metabolism diseases.
Eight memory researchers investigating their own autobiographical memory
Authors: Sotgiu Igor 
Published: October 2021

AbstractThe present article provides a descriptive review of the studies conducted by eight memory researchers who empirically investigated their own autobiographical memory. They are Francis Galton, Madorah Smith, Marigold Linton, Willem Wagenaar, Steen Larsen, Dorthe Berntsen, Alan Baddeley and Richard White. These authors assessed their ability to remember their personal past by means of a range of experimental procedures and materials including personal diaries, letters, cued and free recall tasks. The methods implemented so far allowed memory researchers to obtain relevant findings on a number of issues which are at the heart of the contemporary autobiographical memory debate, that is, forgetting, memory accuracy, phenomenology, memory content and memory organisation. The findings of the individual studies are compared and contrasted with those of conventional autobiographical memory functioning. It is argued that the strengths of the memory researchers' self‐studies of autobiographical memory outweigh their weaknesses.
Non‐fragile state estimation for second‐order memristive neural networks with unbounded time‐varying delays
Authors: Luo Ling , Jian Jigui , Zheng Sheng 
Published: October 2021

SummaryWithout converting the second‐order memristive neural networks (SMNNs) into the usual first‐order systems, this article works on the non‐fragile state estimation of SMNNs with unbounded time‐varying delays. The memristor is treated as uncertainty by recommending some measurable functions. According to Lyapunov functional approach, inequality techniques, and combining Barbalat lemma, a new Lyapunov functional is proposed to straightway discuss the asymptotic stability for the error system, and several sufficient conditions are obtained to assure the existence of the preset estimators. The nonfragile estimators are designed and several explicit descriptions of the estimators are given by solving linear matrix inequalities. To overcome the uncertainty of state variables, the problem of parameter mismatch is as well considered. Finally, two examples are given to verify the availability of the results.

AbstractPermanent magnets are applied in many large‐scale and emerging applications and are crucial components in numerous established and newly evolving technologies. Rare‐earth magnets exhibit excellent hard magnetic properties; however, their applications are limited by the price and supply risk of the strategic rare‐earth elements. Therefore, there is an increasing demand for inexpensive magnets without strategic elements. Here, the authors report the intrinsic highly‐anisotropic magnetic properties of Co and Si co‐doped single crystals (Fe1−yCoy)2P1−xSix (y ≈ 0.09). Co increases Curie temperature TC; Si doping decreases magnetocrystalline anisotropy K1 and also increases TC significantly because of the enhanced interlayer interaction. The maximum room temperature magnetocrystalline anisotropy K1 = 1.09 MJ m−3 is achieved for x = 0.22, with saturation magnetization µ0Ms = 0.96 T and TC = 506 K. The theoretical maximum energy product is one of the largest for any magnet without a rare earth or Pt. Besides its promising intrinsic magnetic properties and absence of any strategic elements, other advantages are phase stability at high temperatures and excellent corrosion resistance, which make this material most promising for permanent magnetic development that will have a positive influence in industry and daily life.

AbstractSolid‐state electrolytes (SSEs) with sufficient ionic conduction, wide voltage window, flexible‐rigid interface, and ease of processibility are determinative to the development of energy‐dense solid‐state lithium metal batteries. Due to the low density and interfacial compatibility, polyether SSE has been studied for decades but remains handicapped by the inherently low ionic conductivity and insufficient voltage window. In this contribution, an ion‐dipole‐reinforced poly‐3‐hydroxymethyl‐3‐methyloxetane is demonstrated as a novel SSE and major substitution to conventional poly(ethylene oxide). By further polypropylene skeleton compositing, the composite solid electrolyte (PHMP) synergistically achieves high voltage tolerance (4.6 V), high ion‐conduction (25 °C, 1.26 × 10−4 S cm−1), and flexible‐rigid mechanical properties. Cryo‐transmission electron microscope has revealed a columnar Li deposition and LiF‐rich solid electrolyte interface, suggesting excellent dendrite suppression. According to density functional theory, the densely branched ether–oxygen groups play an important role as ion solvation cages, favoring strong Li+‐coordination and fast diffusion kinetics. More importantly, it restrains the proton‐induced decomposition and essentially enhances high‐voltage stability. As a result, PHMP contributes to an improved rate capability, significantly reduced interface impedance, and long‐term cycle stability of Li symmetrical batteries for over 1600 h. PHMP‐modified LiNi0.8Co0.1Mn0.1O2|Li batteries exhibit a high discharge capacity of 211.5 mAh g−1 and desirable cycle stability.

AbstractSpin‐charge interconversion phenomena at the interface between magnetic materials and topological insulators (TIs) are attracting enormous interest in the research effort toward the development of fast and ultra‐low power devices for future information and communication technology. A large spin‐to‐charge (S2C) conversion efficiency in Au/Co/Au/Sb2Te3/Si(111) heterostructures based on Sb2Te3 TIs grown by metal–organic chemical vapor deposition on 4″ Si(111) substrates is reported. By conducting room temperature spin pumping ferromagnetic resonance, a 250% enhanced charge current due to spin pumping in the Sb2Te3‐containing system is measured when compared to the reference Au/Co/Au/Si(111). The corresponding inverse Edelstein effect length λIEE ranges from 0.28 to 0.61 nm, depending on the adopted methodological analysis, with the upper value being so far the largest observed for the second generation of 3D chalcogenide‐based TIs. These results open the path toward the use of chemical methods to produce TIs on large area Si substrates and characterized by highly performing S2C conversion, thus marking a milestone toward future technology‐transfer.

Published: October 2021

AbstractTwo materials, 3‐(4‐(9H‐carbazol‐9‐yl)benzo[4,5]thieno[3,2‐d]pyrimidin‐2‐yl)‐5‐(triphenylsilyl)benzonitrile (CzBTPCNmSi) and 9‐(2‐(3‐(triphenylsilyl)phenyl)benzo[4,5]thieno[3,2‐d]pyrimidin‐4‐yl)‐9H‐carbazole‐3‐carbonitrile (CNCzBTPmSi), are synthesized as the N‐type host (electron‐transport type host) of a mixed host, harvesting triplet excitons of the blue phosphor by engineering the charge transfer character using a CN unit. The two host materials are based on benzothienopyrmidine modified using CN, tetraphenylsilyl, and carbazole groups to control the lowest unoccupied molecular orbital level, manage their intermolecular packing, and stabilize the molecule against holes, respectively. The two hosts are mixed with a P‐type 3,3‐di(9H‐carbazol‐9‐yl)biphenyl (mCBP) to offer a mixed host for sky and deep blue‐emitting phosphors. In the device applications, CzBTPCNmSi and CNCzBTPmSi show high external quantum efficiency (EQE) (around 24% in the sky‐blue devices), whereas only CNCzBTPmSi exhibited high EQE (above 20% in the deep blue devices) due to high triplet energy. Moreover, the CNCzBTPmSi demonstrates a longer device lifetime than the control host without the CN unit. Thus, CN engineering can manage the triplet energy, EQE, and device lifetime of blue phosphorescent devices by controlling the charge transfer character.
Analytical Model of the Piezoresistive Behavior of Highly Compressible Sensors Made of Microporous Nanocomposites
Authors: Zhang Jianpeng , Wang Ziya , Peng Zhengchun 
Published: October 2021

AbstractMicroporous conductive nanocomposites, compared with conventional filler‐matrix composites, enable flexible piezoresistive sensors with higher sensitivity and a larger measurement range. Previous research focuses on different methods of fabricating porous materials that are highly sensitive to pressure, however, there is only a small amount of research studying the mechanism of those sensors. Without an appropriate theoretical guide, relying on expensive experimental approaches to enhance the sensitivity will significantly limit the advancement of this technology. This article proposes an efficient analytical model, with some parameters determined from experiments, to investigate the piezoresistive behaviors of microporous nanocomposites. The predicted results agree well with the analysis from finite element models as well as the experimental data. Moreover, scaling law is applied to study the effect of geometry, material, and interface on the sensitivity of the sensor. This study establishes the theoretical foundation for the design of a high‐performance piezoresistive sensor based on microporous nanocomposites.
Charge Transfer at the Hetero‐Interface of WSe2/InSe Induces Efficient Doping to Achieve Multi‐Functional Lateral Homo‐Junctions

Published: October 2021

AbstractCharge transfer at the hetero‐interface is at the center of van der Waals (vdWs) heterostructure devices for multi‐functional applications. Compared with the extensively investigated photogenerated carrier transfer driven by the built‐in electric field from the conduction or valence band offset, the charge transfer due to the Fermi level difference of the two adjacent constitutes, and its influence on the opto‐/electronic performance of vdWs heterostructure devices are not clarified. Herein, by taking an example of WSe2/InSe heterostructure, it is demonstrated that the charge transfer at the hetero‐interface is an efficient “doping” strategy to dramatically modulate the carrier densities of atomically thin counterparts due to the extension of “band bending” across the entire heterostructure, paving the way for the creation of lateral WSe2 p‐n and n‐n+ homo‐junctions with multi‐functionalities, including promising rectification, photovoltaic, and photodetection abilities. Moreover, the device physics of lateral homo‐junctions, including potential distribution, band diagram, and photocurrent generation mechanisms, is revealed by gate‐dependent Kelvin probe force microscopy and scanning photocurrent measurements. This work not only provides a general avenue to build 2D lateral homo‐junctions, but also give deeper insights into the device physics of the junctions by coupling scanning probe and scanning photocurrent techniques.
