Wooden Panel Inscribed for Amasis
Authors: Bianchi Robert Steven
Published: November 2022

A wooden, openwork panel inscribed for Amasis and embellished with secondary glass inlays and gilding was disco- vered in 2018 by the Franco-Swiss Archaeological Mission at South Saqqara in a disturbed, archaeological context littered with bovine skeletal remains in the southern section of the pyramid complex of queen Ankhnespepy II. The panel’s openwork design finds its closest parallels in two-dimensional representations of funerary furnishing that suggest that this particular object formed part of the panoply of a sacred animal, suggested to have been a bull, the cults of which were supported by Amasis at Saqqara. Those comparisons call into question the function of all of the wooden panels embellished with glass inlays dated to the Late Period (given in Appendix) and whether the term, naos, is an appropriate designation for all such objects.

Finding the Village
Authors: Ghabriel Ikram , Quirke Stephen
Published: November 2022

Historians and archaeologists tend to detach sites and objects in urban and rural settings from the people living there, as neglected treasures awaiting recognition and rescue by an outsider. In this paper, we consider the range of persons and institutions involved in accumulating material evidence for the Ramesside artists who worked on the tombs in the Valley of the Kings and lived in a village between the Theban desert cliffs and the fields. A first wave of extracting their monuments, in the late 1810s, offers an opportunity to investigate the processes involved in collecting antiqui- ties, and the relations between the protagonists—local, international, and intermediary. We argue that a focus on questions of historical method and sources would increase precision on statements of provenance in collections and help to align a more self-critical history of archaeology with the primary aim of others to understand a past society.

Keeping It in the Family
Authors: Green Gemma F. P.
Published: November 2022

The first half of Egypt’s Fifth Dynasty saw a number of administrative and ideological changes. For the first time, officials of non-royal descent were able to hold positions within the higher levels of the administration, and Re became an integral part of the dogma of divine kingship. These occurrences may have caused some concern for the king, who seems to have taken profound measures to ensure that both his administration and Re’s powerful priesthood remained under his control. The titulary of two successive officials, Seshathetep [G 5150] and Kanefer [Dahshur no. 28, EA 1324 and EA 1345], demonstrate that the vizierate and the High Priesthood of Re were held by the same royal official for much of the Fifth Dynasty. The concentration of these two titles into the hands of the same individual is previously unattested and may indicate some apprehension about the dispersion of these titles amongst the non-royal administration, and perhaps the need to keep the Re cult under the king’s watchful eye. Using blood ties to ensure that these officials were loyal, trustworthy and reliable may have created a much-needed sense of security for the king, who may have been unsure about the integrity of his newly appointed court.

Uma reforma trabalhista paralela: a tentativa de aplicação dos princípios da Lei da Liberdade Econômica às relações de trabalho em descompasso com a proteção constitucional conferida ao valor social do trabalho
Authors: Perez Daisy Doro , De Oliveira Lourival José
Published: November 2022

O estudo promove uma análise da aplicação dos princípios da Lei nº 13.874 de 20 de setembro de 2019 às relações de trabalho e o seu descompasso com as proteções constitucionais. Seu objetivo foi investigar a possível ocorrência de uma reforma trabalhista paralela, sem a realização de alterações diretas na legislação infraconstitucional. Para tanto, explorou-se o sentido constitucional do princípio da livre iniciativa, na perspectiva da sustentabilidade, analisando-se o papel do Estado. Em seguida, foram estudados os novos parâmetros trazidos pela lei, no tocante à ampliação da liberdade contratual, limitação da atuação do Estado e redefinição da função social e sua aplicação às novas relações de trabalho, sob o prisma do princípio da primazia da realidade. Concluiu-se que o processo de reforma trabalhista está prosseguindo através de uma redução do campo de incidência do direito laboral, comprometendo a extensão das suas normas protetivas a um maior contingente de trabalhadores, sendo necessário restabelecer o entendimento a respeito dos princípios da livre iniciativa e da autonomia da vontade, para se efetivar os valores sociais constitucionalmente estabelecidos. Adotou-se o método dedutivo, com pesquisas doutrinárias e uma análise crítica sobre o processo contínuo da desregulamentação das relações de trabalho.

Published: November 2022

Background

Genetic diversity is fundamental for the survival of species. In particular, in a climate change scenario, it is crucial that populations maintain genetic diversity so they can adapt to novel environmental conditions. Genetic diversity in wild agaves is usually high, with low genetic differentiation among populations, in part maintained by the agave pollinators such as the nectarivorous bats. In cultivated agaves, patterns of genetic diversity vary according to the intensity of use, management, and domestication stage. In Agave tequilana Weber var. azul (A. tequilana thereafter), the plant used for tequila production, clonal propagation has been strongly encouraged. These practices may lead to a reduction in genetic diversity.

Methods

We studied the diversity patterns with genome-wide SNPs, using restriction site associated DNA sequencing in cultivated samples of A. tequilana from three sites of Jalisco, Mexico. For one locality, seeds were collected and germinated in a greenhouse. We compared the genomic diversity, levels of inbreeding, genetic differentiation, and connectivity among studied sites and between adults and juvenile plants.

Results

Agave tequilana presented a genomic diversity of HT = 0.12. The observed heterozygosity was higher than the expected heterozygosity. Adults were more heterozygous than juveniles. This could be a consequence of heterosis or hybrid vigor. We found a shallow genetic structure (average paired FST = 0.0044). In the analysis of recent gene flow, we estimated an average migration rate among the different populations of m = 0.25. In particular, we found a population that was the primary source of gene flow and had greater genomic diversity (HE and HO), so we propose that this population should continue to be monitored as a potential genetic reservoir.

Discussion

Our results may be the consequence of more traditional management in the studied specific region of Jalisco. Also, the exchange of seeds or propagules by producers and the existence of gene flow due to occasional sexual reproduction may play an important role in maintaining diversity in A. tequilana. For populations to resist pests, to continue evolving and reduce their risk of extinction under a climate change scenario, it is necessary to maintain genetic diversity. Under this premise we encourage to continue acting in conservation programs for this species and its pollinators.
Late Diagnosed Hirschsprung Disease: A Case Report
Authors: Khare Shrayash , Tejada Omaira , Mendez Magda
Published: November 2022

Hirschsprung Disease (HD) is mainly a diagnosis of the neonatal period. It is mostly suspected within the first few days of life, the classical telltale sign is an infant not passing meconium. Paediatricians continue to encounter cases of late diagnosed HD. A late diagnosis of Hirschsprung poses an unnecessary burden and suffering on the child and family and increases the likelihood of longterm health complications for the patient. Hirschsprung-Associated Enterocolitis (HAEC) is one of the acute serious complications of late diagnosed HD. It is the leading cause of morbidity and is responsible for half of the deaths associated with Hirschsprung disease. Hence, HAEC should be kept in mind as a probable diagnosis by evaluating physicians particularly when making assessments for a child with possible necrotising enterocolitis or distal bowel obstruction with loose stools. This case report highlights the importance of keeping HD on the differential diagnosis of an ill-appearing child presenting with growth faltering below growth curve for age and in settings of chronic constipation. The patient discussed in this case evolved from an admission due to poor weight gain and fever to concerns for paediatric surgery evaluation. Her symptoms progressed to include not just clinical changes, but also physical examination reflected worsening abdominal exams. Patient underwent biopsy which showed aganglionic bowel segment which resulted in surgical resection. Patient had complete recovery without major complications at two weeks postsurgery

Published: November 2022

Introduction: Rosacea is a chronic inflammatory disease that affects the facial skin with eye involvement being underdiagnosed. Aim: To study the prevalence of ocular rosacea in patients of rosacea in a tertiary care centre. Materials and Methods: The present study was a cross-sectional study conducted at two tertiary level hospitals from January 2020 to December 2021. Cases of rosacea diagnosed were referred from the Departments of dermatology to the Departments of ophthalmology for ocular evaluation. A total of 400 patients were included in study in a multicentric setting. For ophthalmic evaluation, Ocular Surface Disease Index (OSDI) questionnaire was used. Results: Total 29 cases (7.25%) had ocular rosacea, out of 400 dermatological confirmed cases of rosacea. Amongst confirmed ocular rosacea, 12 (41.4%) were males and 17 (58.6%) were females. Most manifestations were noted in 41 to 60 years age with an average age of 52.2 years. Most of the cases presented with multiple symptoms and signs- 19 presented with features of dry eyes,16 had features of conjunctivitis, 6 had blepharitis, and 7 had recurrent chalazions. Conclusion: Ocular rosacea is a diagnostic enigma to clinicians as it is underdiagnosed because of overlapping sign and symptoms. This study emphasises ocular examination in all cases of rosacea.
Determination of C,c,E and e Antigens Section Prevalence in Rh D Negative Individuals: Is it Good Exercise with Utilities in Clinical Blood Transfusion Practices?
Authors: Kahar Manoj A
Published: November 2022

Introduction: Besides D antigen, C,c,E and e antigens of Rh blood group system are the most important antigens involved in alloimmunisation. The prevalence of C,c,E and e antigens in Rh D negative individuals in local population has many utilities in transfusion medicine practice. Aim: To determine the prevalence of C,c,E and e antigens in Rh D negative individuals. Materials and Methods: This prospective observational study was performed at Bhanumati clinical laboratory, Navsari, Gujarat, India, from January 2020 to January 2022. A total of 270 Rh D negative samples irrespective of ABO blood group status were typed for C,c,E and e antigen using monoclonal reagents from two different manufacturers using conventional tube technique. The most likely phenotype and genotype were determined using reference textbooks. Possibility of weak D in these 270 samples was ruled out using polyspecific Antihuman Globulin Reagent performing test for weak D antigens. Results were analysed using Excel spread sheet. Results: Prevalence of C,c,E, and e antigen in the 270 Rh D negative samples were, C (17, 6.29%), c (267, 98.88%), E (1, 0.37%) and e (270, 100%). Most probable genotypes were dce/ dce(rr), dCe/dce(r’r), dCe/dCe(r’r’) and dcE/dce(r’’r). Conclusion: Data obtained of C,c,E and e antigen prevalence in Rh D negative individuals is having varied utilities in blood transfusion services such as formulating rare blood group registry, preparing in house screening and panel red cells, and maintaining inventory of rare blood group units using freezing technology, if available.
The Water Hyacinth Reduces the Production Costs of Fish Feed during the Small-scale Tilapia Culture in Southern of Sinaloa, Mexico
Authors: Reyes J. Guillermo Galindo
Published: November 2022

Tilapia culture is increasing such in Mexico as in other countries of world; however, one of main problem is the food cost; therefore, the aim this work was to use water hyacinth as a complement in tilapia feeding, and thus reduce production cost. Dried water hyacinth added with cane molasses, was fermented using Lactobacillus acidophilus. The fermented product was mixed with commercial feed and cornmeal, at 30-60-10 percent respectively. The mixture was extruded and dried to be used as tilapia feed. Tilapia juveniles were placed in plastic ponds; once tilapias reached 24-26 g, were divided in two groups; The experimental group was transferred to a 4,678-liter pond while the control group was distributed in three 100-liter ponds. The experimental group was fed with food prepared with water hyacinth, while control group with commercial food. To know the tilapias growth of each groups, the weight gain of both groups, was recorded every 2 weeks; also to check the water state, its physicochemical parameters were recorded. At end of 9 biweeklies, the experiment was stopped, and the tilapia growth of both groups compared, using a von Bertalanffy modified equation to calculate the growth, based on the weight increase. Results indicated that tilapia growth rate fed with water hyacinth-supplemented feed, was 7.5% higher than tilapia fed with commercial feed, at p=0.05. Another important point, is that feed cost prepared with water hyacinth was 30% lower than commercial food. This results demonstrate that tilapia farming to small and medium-scale, can be developed in southern Sinaloa, which will create jobs for inhabitants of small communities, strengthening the family economy and the social fabric.

Aims: Neglected or underutilized plant species, such as sapodilla (Manilkara zapota), which play a substantial role in the livelihoods of populations but whose potential remains still under-exploited, deserve particular attention from researchers to a better knowledge of its food applications. This study aims to develop a novel drink based on sapodilla fruit and other known ingredients with acceptable sensory, microbiological and physicochemical characteristics.

Place and Duration of Study: The study was carried out at Ecole des Sciences et Techniques de Conservation et de Transformation des Produits Agricoles of the Université Nationale d'Agriculture (UNA) in Benin between June and September 2021.

Methodology: Flavored beverages with the essential oil of Cymbopogon citratus were formulated from sapodilla puree and pineapple juice following a mixing plan. The microbiological, organoleptic and physicochemical analyzes of formulated cocktail were then carried out by standard methods.

Results: All the formulated drinks presented a satisfactory microbiological quality. The E5 formula containing 10% of the sapodilla puree and 90% of the juice of pineapple and the essential oil of C. citratus was the most accepted by tasters. This beverage had a pH of 5.46±0.06, a total soluble solid of 17.25±0.35 ºBrix and a specific gravity of 1.08±0.01. The titratable acidity, total ash and dry matter content were 0.80±0.01 g/100g, 0.19±00% and 15.28±1.07 respectively.

Conclusion: The fruit of sapodilla can be valued through good quality drinks which can be popularized after a nutritional characterization.

Authors: Zhang Lu , Gong Rui , Shi Lu , Wen Ming , Sun Xiaoqian , Yabroff K. Robin , Han Xuesong
Published: November 2022

Importance

Residential segregation is a structural risk factor for poor cancer outcomes. Previous research examining the association of residential segregation with cancer outcomes was limited by older data, restricted geographic areas, and few cancer sites. To guide targeted interventions, a comprehensive evaluation of the association between segregation and cancer outcomes is needed.

Objective

To examine the association of residential racial and economic segregation with cancer mortality at the US county level for all cancers combined and for the 13 cancer types that represent the top 10 causes of cancer deaths in males or females.

Design, Setting, and Participants

This ecological study used county-level sociodemographic data from the 2015-2019 American Community Survey linked with 2015-2019 county-level mortality data. Data analysis was performed from September 2021 to April 2022.

Exposures

Residential racial and economic segregation measured by the Index of Concentration at the Extremes (ICE) and categorized into quintiles 1 (most deprived) through 5 (most privileged).

Main Outcomes and Measures

Age-adjusted cancer mortality was the outcome. Multilevel linear mixed modeling was used to calculate the adjusted mortality rate ratio (aRR).

Results

A total of 3110 counties were included. The age-adjusted mortality rates of all cancers combined were 179.8, 177.3, 167.6, 159.6, and 146.1 per 100 000 population (P < .001 for trend) for the 5 ICE categories (most deprived to least deprived), respectively. Compared with the least deprived counties, aRRs for all cancers combined were 1.22 (95% CI, 1.20-1.24) for the most deprived counties, followed by 1.17 (95% CI, 1.15-1.19), 1.10 (95% CI, 1.09-1.12), and 1.06 (95% CI, 1.04-1.08) for the other 3 quintiles, respectively (P < .001 for trend). Segregation was associated with increased mortality from 12 of 13 selected cancer sites, in which aRRs ranged from 1.06 (95% CI, 1.02-1.09) for brain and other nervous system cancer to 1.49 (95% CI, 1.43-1.54) for lung and bronchus cancer.

Conclusions and Relevance

The findings of this ecological study suggest that residential racial and economic segregation is associated with higher cancer mortality at the county level, highlighting opportunities for geographically targeted cancer prevention and control efforts.
Lateral Root Formation
Authors: Bellande Kevin , Laplaze Laurent , Guyomarc'h Soazig
Published: November 2022

The underground development of the plant root system is a complex and plastic process. It enables the plants to mine hydromineral resources while dealing with changes in their environment. Root branching via lateral root formation is considered as an important trait because it greatly influences root system architecture and impacts plant growth and crop performance. In the past few years, major progresses in understanding the mechanisms of root branching have been made. Technical advances lift the veil on multiple molecular and cellular processes that contribute to the robust formation of new lateral roots in plant models and to its response to endogenous and environmental cues. Developing translational approaches should increase in the coming decades to allow a global and integrative vision of root system development and the mechanisms of root branching in various plant species. Moreover, exploring the genetic diversity that modulates this fundamental process opens the way to breeding crops with more efficient root system architectures.

Key Concepts

Lateral root formation significantly influences root system architecture, a key trait for plant interaction with the soil and especially, plant nutrition.

Lateral root primordium initiation, development and emergence from the primary root have been well described in several plant model species.

Lateral root formation is highly regulated. Many molecular mechanisms involved in this organogenesis process are known in detail, especially in the plant modelArabidopsis thaliana.

Among these, the phytohormone auxin is a key regulatory signal influencing each step of lateral root formation.

A complex regulatory network, integrating intercellular signals and mechanical constraints, triggers regularly spaced initiation of lateral root formation, allows robust organ patterning, and controls the lateral root primordium growth through the overlaying primary root tissues.

Endogenous and environmental signals modulate lateral root formation kinetics and emergence, yielding plasticity in root system development.

Comparison of lateral root development in different plant species reveals specific and conserved pathways.

Genetic diversity can be explored and used to breed crops with optimised root branching properties.
IoT enabled lung cancer detection and routing algorithm using CBSOA‐based ShCNN

Published: November 2022

The Internet of Things (IoT) has tremendously spread worldwide, and it influenced the world through easy connectivity, interoperability, and interconnectivity using IoT devices. Numerous techniques have been developed using IoT‐enabled health care systems for cancer detection, but some limitations exist in transmitting the health data to the cloud. The limitations can be accomplished using the proposed chronological‐based social optimization algorithm (CBSOA) that effectively transmits the patient's health data using IoT network, thereby detecting lung cancer in an effective way. Initially, nodes in the IoT network are simulated such that patient's health data are collected, and for transmission of such data, routing is performed in order to transmit the health data from source to destination through a gateway based on cloud service using CBSOA. The fitness is newly modeled by assuming the factors like energy, distance, trust, delay, and link quality. Finally, lung cancer detection is carried out at the destination point. At the destination point, the acquired input data is fed to preprocessing phase to make the data acceptable for further mechanism using data normalization. Once the feature selection is done using Canberra distance, then the lung cancer detection is performed using shepard convolutional neural network (ShCNN). The process of routing as well as training of ShCNN is performed using the CBSOA algorithm, which is devised by the inclusion of the chronological concept into the social optimization algorithm. The proposed approach has achieved a maximum accuracy of 0.940, maximum sensitivity of 0.941, maximum specificity of 0.928, and minimum energy of 0.452.

1D perovskite materials are of significant interest to build a new class of nanostructures for electronic and optoelectronic applications. However, the study of colloidal perovskite nanowires (PNWs) lags far behind those of other established perovskite materials such as perovskite quantum dots and perovskite thin films. Herein, a dual‐phase passivation strategy to synthesize all‐inorganic PNWs with minimized surface defects is reported. The local phase transition from CsPbBr3 to CsPb2Br5 in PNWs increases the photoluminescence quantum yield, carrier lifetime, and water‐resistivity, owing to the energetic and chemical passivation effect. In addition, these dual‐phase PNWs are employed as an interfacial layer in perovskite solar cells (PSCs). The enhanced surface passivation results in an efficient carrier transfer in PSCs, which is a critical enabler to increase the power conversion efficiency (PCE) to 22.87%, while the device without PNWs exhibits a PCE of 20.74%. The proposed strategy provides a surface passivation platform in 1D perovskites, which can lead to the development of novel nanostructures for future optoelectronic devices.

Future active metamaterials for reconfigurable structural applications require fast, untethered, reversible, and reprogrammable (multimodal) transformability with shape locking. Magnetic control has a superior advantage for fast and remotely controlled deployment; however, a significant drawback is needed to maintain the magnetic force to hold the transformation, limiting its use in structural applications. The shape‐locking property of shape‐memory polymers (SMPs) can resolve this issue. However, the intrinsic irreversibility of SMPs may limit their reconfigurability as active metamaterials. Moreover, to date, reprogrammable methods have required high power with laser and arc welding proving to be energy‐inefficient control methods. In this work, a magneto‐thermomechanical tool is constructed and demonstrated, which enables a single material system to transform with untethered, reversible, low‐powered reprogrammable deformations, and shape locking via the application of magneto‐thermomechanically triggered prestress on the SMP and structural instability with asymmetric magnetic torque. The mutual assistance of two physics concepts—magnetic control combined with the thermomechanical behavior of SMPs is demonstrated, without requiring new materials synthesis and high‐power energy for reprogramming. This approach can open a new path of active metamaterials, flexible yet stiff soft robots, multimodal morphing structures, and mechanical computing devices where it can be designed in reversible and reprogrammable ways.

Biofilm infection has a high prevalence in chronic wounds and can delay wound healing. Current treatment using debridement and antibiotic administration imposes a significant burden on patients and healthcare systems. To address their limitations, a highly efficacious electrical antibiofilm treatment system is described in this paper. This system uses high‐intensity current (75 mA cm−2) to completely debride biofilm above the wound surface and enhance antibiotic delivery into biofilm‐infected wounds simultaneously. Combining these two effects, this system uses short treatments (≤2 h) to reduce bacterial count of methicillin‐resistantS. aureus(MRSA) biofilm‐infected ex vivo skin wounds from 1010to 105.2colony‐forming units (CFU) g−1. Taking advantage of the hydrogel ionic circuit design, this system enhances the in vivo safety of high‐intensity current application compared to conventional devices. The in vivo antibiofilm efficacy of the system is tested using a diabetic mouse‐based wound infection model. MRSA biofilm bacterial count decreases from 109.0to 104.6CFU g−1at 1 day post‐treatment and to 103.3CFU g−1at 7 days post‐treatment, both of which are below the clinical threshold for infection. Overall, this novel technology provides a quick, safe, yet highly efficacious treatment to chronic wound biofilm infections.

Vertically‐stacked organic light emitting diode (OLED) microcavities form 1D metal‐dielectric photonic crystals (MDPC) with many degrees of freedom for engineering complex emission profiles. The photonic band structure of the MDPC OLED is determined by the underlying unit cell and is particularly sensitive to the properties of the metallic electrodes. The electronic requirements of microcavity OLED fabrication often necessitate dissimilar metallic electrodes to achieve good performance. This can profoundly impact the photonic properties of a MDPC by doubling the unit cell length. This work presents a MDPC OLED formed with single‐cavity unit cells by employing optically similar Ag alloys as the semi‐transparent electrode materials. The crystal is found to display a single photonic band without a band gap up to eight stacked cavities. The states within the band are evenly‐spaced and clearly resolved, which is critical for applications seeking to utilize specific photonic states. Design considerations are presented for optimizing the photonic behavior of MDPC OLEDs through selective control of the optical properties of metallic alloys.

Measuring flow of gases is of fundamental importance yet is typically done with complex equipment. There is, therefore, a longstanding need for a simple and inexpensive means of flow measurement. Here, gas flow is measured using an extremely simple device that consists of an Ar plasma‐treated polydimethylsiloxane (PDMS) slab adhered on a glass substrate with a tight seal. This device does not even have a channel, instead, gas can flow between the PDMS and the glass by deforming the PDMS wall, in other words, by making an interstice as a temporary path for the flow. The formation of the temporary path results in a compressive bending stress at the inner wall of the path, which leads to the formation of well‐ordered wrinkles, and hence, the emergence of structural color that changes the optical transmittance of the device. Although it is very simple, this setup works sufficiently well to measure arbitrary gases and analyzes their flow rates, densities, and viscosities based on the change in color. It is also demonstrated that this technique is applicable to the flow‐induced display of a pattern such as a logo for advanced applications.

Miniaturized ultrafast switchable optical components with high efficiency and broadband response are in high demand to the development of optical imaging, sensing, and high‐speed communication. Sharp Fano‐type resonance switched by active materials is one of the key concepts that underpins the control of light in metaoptics with high sensitivity. However, actuating such metasurfaces exhibits a long‐standing trade‐off between modulation depth and operational bandwidth. Here, the limitations are circumvented by theoretical analysis, numerical simulation, and experimental realization of an achromatic Fano metasurface so that a high contrast of tunability with ultrafast switching rate over a broad range of frequency is achieved. By developing the physics of inter‐mode coupling, the Fano metasurface is designed according to a complete phase diagram derived from coupled mode theory. Unlike conventional Fano metasurfaces, the cross‐polarized inter‐metaatoms coupling is discovered as a superior ability of high‐efficiency broadband achromatic polarization conversion. To prove the ultrasensitive nature, a metadevice is constructed by incorporating a thin amorphous Ge layer with a weak photoconductivity perturbation. Transmission modulation over broadband frequency range from 0.6 to 1.1 THz is thus successfully realized, featuring its merits of modulation depth over 90% and On–Off–On switching cycle less than 10 ps.

The volume change of the silicon anode seriously affects the electrode integrity and cycle stability. Herein, a binder, GCA13, with energy dissipation function and surface stability effect is proposed to enhance the cycle life and specific capacity. Unlike traditional binders that protect silicon electrodes through long‐chain networks, GCA13 introduces citric acid molecules with short‐range functions on the long‐chain guar gum through weak interconnection. This short‐range action is similar to the function of a spring, which can effectively buffer the silicon particle pulverization caused by the volume change. Therefore, the electrode can effectively maintain structural integration with ignorable cracks and alleviated thickness swelling. Thus, the Si@GCA13 anode exhibits a high reversible capacity of 1184 mAh g−1 under 2 A g−1 after 740 cycles with a latter coulombic efficiency of 99.9%. Extraordinarily, benefiting from the superior properties of the GCA13 binder, the electrode shows remarkable cycling stability under low (−15 and 0 °C) and high temperatures (60 °C). The work demonstrates the great potential of this binder design strategy to achieve the overall property promotion of Si anodes for practical application even under harsh service conditions.

Background

We studied the effect of apolipoprotein E (APOE) ε4 status and sex on rates of cognitive decline in early‐ (EO) and late‐ (LO) onset Alzheimer's disease (AD).

Method

We ran mixed‐effects models with longitudinal cognitive measures as dependent variables, and sex, APOE ε4 carrier status, and interaction terms as predictor variables in 998 EOAD and 2562 LOAD participants from the National Alzheimer's Coordinating Center.

Results

APOE ε4 carriers showed accelerated cognitive decline relative to non‐carriers in both EOAD and LOAD, although the patterns of specific cognitive domains that were affected differed. Female participants showed accelerated cognitive decline relative to male participants in EOAD only. The effect of APOE ε4 was greater in EOAD for executive functioning (p < 0.0001) and greater in LOAD for language (p < 0.0001).

Conclusion

We found APOE ε4 effects on cognitive decline in both EOAD and LOAD and female sex in EOAD only. The specific patterns and magnitude of decline are distinct between the two disease variants.

Highlights

Apolipoprotein E (APOE) ε4 carrier status and sex differentiate rates of cognitive decline in early‐onset (EO) and late‐onset (LO) Alzheimer's disease (AD).

APOE ε4 in EOAD accelerated decline in memory, executive, and processing speed domains.

Female sex in EOAD accelerated decline in language, memory, and global cognition.

The effect of APOE ε4 was stronger for language in LOAD and for executive function in EOAD.

Sex effects on language and executive function decline differed between EOAD and LOAD.
