The incidence of gastric cancer (GC) is expected to increase to 1.77 million cases by 2040. To improve treatment outcomes, GC patients are increasingly treated with neoadjuvant chemotherapy (NAC) prior to curative-intent resection. Although NAC enhances locoregional control and comprehensive patient care, survival rates remain poor, and further investigations should establish outcomes assessment of current clinical pathways. Individually assessed parameters have served as benchmarks for treatment quality in the past decades. The Outcome4Medicine Consensus Conference underscores the inadequacy of isolated metrics, leading to increased recognition and adoption of composite measures. One of the most simple and comprehensive is the “All or None” method, which refers to an approach where a specific set of criteria must be fulfilled for an individual to achieve the overall measure. This narrative review aims to present the rationale for the implementation of a novel composite measure, Textbook Neoadjuvant Outcome (TNO). TNO integrates five objective and well-established components: Treatment Toxicity, Laboratory Tests, Imaging, Time to Surgery, and Nutrition. It represents a desired, multidisciplinary care and hospitalization of GC patients undergoing NAC to identify the treatment- and patient-related data required to establish high-quality oncological care further. A key strength of this narrative review is the clinical feasibility and research background supporting the implementation of the first and novel composite measure representing the “ideal” and holistic care among patients with locally advanced esophago-gastric junction (EGJ) and GC in the preoperative period after NAC. Further analysis will correlate clinical outcomes with the prognostic factors evaluated within the TNO framework.

Theories of holistic face processing vary widely with respect to conceptualizations, paradigms, and stimuli. These divergences have left several theoretical questions unresolved. Namely, the role of attention in face perception is understudied. To rectify this gap in the literature, we combined the complete composite face task (allowing for predictions of multiple theoretical conceptualizations and connecting with a large body of research) with a secondary auditory discrimination task at encoding (to avoid a visual perceptual bottleneck). Participants studied upright, intact faces within a continuous recognition paradigm, which intermixes study and test trials at multiple retention intervals. Within subjects, participants studied faces under full or divided attention. Test faces varied with respect to alignment, congruence, and retention intervals. Overall, we observed the predicted beneficial outcomes of holistic processing (e.g., higher discriminability for Congruent, Aligned faces relative to Congruent, Misaligned faces) that persisted across retention intervals and attention. However, we did not observe the predicted detrimental outcomes of holistic processing (e.g., higher discriminability for Incongruent, Misaligned faces relative to Incongruent, Aligned faces). Because the continuous recognition paradigm exerts particularly strong demands on attention, we interpret these findings through the lens of resource dependency and domain specificity.

AbstractTo assess if amnesics have intact remote memory for general semantic information, we examined memory for vocabulary words with known dates of entry into the language between 1955 and 1989. Amnesics of mixed etiology with acute onset performed normally on both a recall and a recognition task. Korsakoff patients, in contrast, were impaired on both tasks and demonstrated a gradient such that their knowledge of words acquired during more recent time periods was worse than that of words acquired during more remote time periods. The improvement in performance associated with recognition testing was larger for Korsakoff patients than for control subjects and correlated significantly with a composite measure of frontal dysfunction. These findings suggest a deficit in the controlled search and retrieval of semantic information in Korsakoff patients. The implications of the differential performance of Korsakoff and mixed etiology amnesics for explanations of temporally graded retrograde amnesia are discussed. (JINS, 1995, I, 443–453.)

Objective:A diagnosis of mild cognitive impairment (MCI) requires memory complaint and objective memory impairment. However, some individuals report subjective memory complaints (SMC) despite having intact memory performance, while others demonstrate subtle impairment on memory testing but have no memory complaints; neither case would meet criteria for MCI. This study aimed to compare memory performances over time in individuals who do not meet traditional MCI criteria to those with normal cognition and those who converted to MCI.Participants and Methods:Diagnoses for a longitudinal sample from the Texas Alzheimer’s Research and Care Consortium were reviewed by a consensus panel of neuropsychologists and neurologists and reclassified at time of last visit. Diagnostic categories included SMC (i.e., memory complaint but no impairment on testing), objective cognitive impairment but no complaint (Impaired but not MCI), normal control (NC), MCI, and dementia. In this study, 827 participants were divided into 4 groups: 1) NC over 5 visits (n=511, 71% female; 42% Latinx/Hispanic), 2) baseline NC to amnestic MCI (n=62; 63% female; 57% Latinx/Hispanic), 3) SMC at last visit (n=133; 58% female; 70% Latinx/Hispanic), and 4) impaired but not MCI at last visit (n=121; 71% female; 60% Latinx/Hispanic). A memory composite (z-score) was created from the CERAD list-learning task (immediate, delayed, and recognition-discrimination) and Wechsler Memory Scale (Immediate and Delayed Logical Memory and Visual Reproduction) to evaluate memory performance over time. A linear mixed-model adjusting for age, education, sex, ethnicity, and number of APOE e4 alleles evaluated memory performance across 5 visits for the groups. To assess if depression followed a similar course, a linear mixed-model evaluated Geriatric Depression Scale (GDS) scores over time.Results:At baseline, groups differed by age (F=22.82; p<.001), education (F=8.60; p<.001), MMSE scores (F=9.38; p<.001), GDS-30 scores (F=3.56; p=.015), and memory composites (F=24.29; p<.001). A significant group X time interaction was observed (F=4.83, p<.001). Memory performance improved in both the SMC and the NC groups, remained stable in the impaired but not MCI group, and declined (as expected) in those who converted to amnestic MCI. Depression scores also showed a significant group X time interaction (F=2.43; p=.004), in which the NC to MCI group endorsed slightly more depression symptoms over time, while other groups declined or remained stable.Conclusions:Memory trajectories in this diverse sample differed across groups. Individuals with SMC but without objective memory impairment and normal controls showed some improvement in memory over time, presumably due to practice effects. Those with subtle memory impairments but no complaint (i.e., did not meet MCI criteria) remained stable and those who converted to amnestic MCI had worse memory across time. The stability of memory performances in the impaired not MCI group suggests these subtle memory inefficiencies may be longstanding or unperceived. However, because our sample achieved retrospective diagnoses of SMC and impaired not MCI, it will be important for future studies to prospectively follow these groups to determine which risk factors may predict progression to MCI and what impact ethnicity may have on these trajectories.

In an article published thirteen years ago, I tried to break new ground by showing that the texts transmitted under the titleCataleptonas the work of Virgil can be seen to form an elaborately arranged and highly allusive book of verse written by a single author. This latter, I argued, was identical with the anonymous poet who, in an epilogue, represents the preceding poems as the juvenilia of the author later known for hisBucolics,GeorgicsandAeneidand, consequently, is himself speaking in the alleged early works asVirgil impersonator. This anonymous poet, however, cannot rightly be labelled a literary forger, since he repeatedly and quite unmistakably recalls each of Virgil's threeoperaas well as other texts written after the year 19b.c. Evidently, then, he is inviting his readers to take part in a literarylusus, one in which they are expected to be familiar not only with the texts ofBucolics,GeorgicsandAeneidbut also with the life of the man who wrote them. The fiction of a young Virgil is created, one who wrote his first poems—the verses referred to in the epilogue aselementaandrudis Calliope(Catal.18[15])—primarily under the influence of Catullus, the said poems being, with the exception ofCatal.12(9) and 16(13), epigrams. My interpretation has borne fruit, with Irene Peirano and Markus Stachon each devoting, in 2012 and 2014 respectively, a monograph to this approach and offering what are often very thorough analytical readings of the poems as the creations of aVirgil impersonator. However, neither of these two Latinists has considered one particular interpretative aspect, which I myself had only been able to introduce very briefly into my paper: the recognition that, as many more recent studies have now further corroborated, Roman poetry books were designed for linear, sequential reading, that they have, as it were, a story to tell. Peirano, moreover, disregards in her study the threePriapeapositioned in editions before the other fifteen epigrams and shown there with their own separate numbering. In the manuscripts, however, the titleCataleptonrefers without exception to a unit comprising the threePriapeaand the fifteen epigrams. The titlePriapea, found in the catalogue of the Murbach manuscripts and in some codices (for example the Graz fragment), is always attached solely to the poemQuid hoc noui est?In theVita Suetoniana-Donatiana(VSD), the termsCatalepton,PriapeaandEpigrammatawere evidently used as three different titles; the author (or his source) may not have seen thatCataleptonis the title of all the poems. Furthermore, I should like to point out that, counted together, ‘Virgil's’Priapeaand epigrams come to a total of seventeen poems and so match precisely both the total of seventeen books in the real Virgil's three works and the total number of Horace's epodes, of the poems, that is, which the not-so-real Virgil quite conspicuously evokes in his own penultimate poem (Catal.16[13]). More significantly, however, a sequential reading of thePriapea et Epigrammatacan in fact build a watertight case for taking the texts to be, as it were, a composite whole, and that is what I intend to argue in the rest of the article.

AbstractProsthetic hands play a vital role in restoring forearm functionality for patients who have suffered hand loss or deformity. The hand gesture intention recognition system serves as a critical component within the prosthetic hand system. However, accurately and swiftly identifying hand gesture intentions remains a challenge in existing approaches. Here, a real‐time motion intention recognition system utilizing liquid metal composite sensor bracelets is proposed. The sensor bracelet detects pressure signals generated by forearm muscle movements to recognize hand gesture intent. Leveraging the remarkable pressure sensitivity of liquid metal composites and the efficient classifier based on the optimized recognition algorithm, this system achieves an average offline and real‐time recognition accuracy of 98.2% and 92.04%, respectively, with an average recognition speed of 0.364 s. Thus, this wearable system shows advantages in superior recognition speed and accuracy. Furthermore, this system finds applications in master‐slave control of prosthetic hands in unmanned scenarios, such as electrically powered operations, space exploration, and telemedicine. The proposed system promises significant advances in next‐generation intent‐controlled prosthetic hands and robots.

The purpose of this article is to demonstrate how equity audits can be used as a tool to expose disparate achievement in schools that, on the surface and to the public, appear quite similar. To that end, the researcher probed beyond surface-level performance composite scores into deeper, more hidden data associated with state-recognized "Honor Schools of Excellence." How is "excellence" defined and operationalized in these schools? Are these schools "excellent" for all students? Can a school really be classified by the state as "excellent" and yet still have significant "gaps" and disparities? If so, is the state's formula used to identify exemplary schools too simple, dogmatic, and institutionally flawed? Through the use of equity audits, quantitative data was collected to scan for systemic patterns of equity and inequity across multiple domains of student learning and activities within 24 elementary schools. The intent was to document and distinguish between schools that are promoting and supporting both academic excellence (small gap schools; SGS) and systemic equity and schools that are not (large gap schools; LGS). Results reveal that although demographic, teacher quality, and programmatic audits all indicated a fair amount of equity between SGS and LGS, the achievement audit between both types of schools indicated great disparities. By controlling for or eliminating some of the external variables and internal factors often cited for the achievement gaps between white middle-class children and children of color or children from low-income families, the findings from this study raise more questions than answers. Results do indicate that equity audits are a practical, easy-to-apply tool that educators can use to identify inequalities objectively.

Purpose The education services sector faces ever-changing global market dynamics with creative disruptions. Building knowledge brands can push the higher education sector beyond its geographical boundaries into the global arena. This study aims to identify key constructs, their theoretical background and dimensions that aid in building a global knowledge brand. The authors' research focuses on adapting and validating scales for global knowledge and education services brands from well-established academic literature. Design/methodology/approach The authors have adopted a mixed methodology approach and a systematic literature review. Authors interviewed 18 subject matter experts as part of content and face validity to arrive at select constructs, dimensions and items. Quantitative methods with random sampling were adopted as the primary methodology. Initially, the survey was administered to 390 students to test preliminary results. The survey was also administered to 5,112 students at a later part of this study. Valid responses stood at 3,244 with a 63% response rate. Further, the authors conducted confirmatory factor analysis, exploratory factor analysis and structural equation modeling to test the reliability and validity of scales. This study analyzed composite reliability, convergent validity and discriminant validity to finalize items for scales. The authors also validated the hypotheses based on the discriminant validity assessment scores. Findings Authors' key research findings are that academic stimulus, campus infrastructure and student intent play a significant role in campus culture and events design and experience at campus. Authors were able to bring out 16 key constructs and 55 critical dimensions vital to global education services brand building. This study also adapted and validated 99 items that meet construct validity and composite reliability criteria. This study also highlights that constructs such as student intent, academic stimulus, campus infrastructure scalability, selection mechanism, pedagogical content knowledge, brand identity, events experience and campus culture play a vital role in global brand recognition. Research limitations/implications The authors' work is fairly generalizable to education services and the higher education sector. However, this study must be extrapolated and empirically validated in other industry sectors. The research implications of this study are that it aided the authors in building theoretical background for student brand loyalty theory, student expectation theory and study loyalty theory. This study adds to the body of knowledge by contributing to theoretical concepts on students, knowledge culture, events, infrastructure and branding. Researchers can adopt the scales proposed in this study to build research models in higher education branding. This study acts as a catalyst for building theories in education services areas. Researchers can delve deep into proposed research aspects of campus infrastructure, knowledge infrastructure, campus knowledge culture, events design and events experience. Practical implications This study aids educators and brand managers to develop global education services and optimize their effort and budget. Administrators in the education services sector must focus on practical aspects of student perception, campus infrastructure, culture and events experience. Practically administrators can reorient their efforts based on this study to achieve global brand recognition. Social implications This study highlights that students are not customers but are co-creators of value in the education sector. This study provides scales and dimensions needed to build co-creation frameworks and models. Originality/value Most research in higher education branding has not covered wider aspects of global brand building. Existing theories proposed in higher education and education services articles cover only narrower aspects of campus infrastructure, culture, events design and branding. This study presents a comprehensive list of critical factors that play a vital role in global knowledge brand building. This study highlights the constructs and scales integral to building a global education services brand.

AbstractIn this paper, preliminary studies on the failure analysis of hybrid composite materials utilizing acoustic emission and machine learning are presented. The main purpose of this study was to analyze the possibilities of using machine learning techniques as a way to better cluster the data obtained from acoustic emission. In this paper, we focus on data preparation, feature extraction (Laplacian score), determination of cluster number (Caliński–Harabasz, Silhouette, and Davies–Bouldin), and testing three clustering techniques, namely K-means, fuzzy C-means, and spectral clustering. The dataset was obtained by testing fiber metal laminates—composites consisting of metal and composite layers. Two experimental tests were realized on pre-cracked rectangular specimens—one with loading in mode I and one with loading in mode II (DCB—double cantilever beam and ENF—end-notch flexural test). Elastic waves were recorded during these tests via an acoustic emission system. Preliminary studies show that the proposed method can be used successfully to cluster data obtained in this way. The obtained dataset was split into 3 clusters (for the ENF test) and 5 clusters (DCB test). In the next stages of the research campaign, based on the presented results, we intend to change the approach to semi-supervised by running additional single-cause damage tests to enhance the achieved results and enable easier damage recognition.

Background: Any clinical feature that may improve the early recognition of, or increase pretest probability of, acute stroke could shorten treatment times. We evaluated the sensitivity and specificity of the "Arm and Leg Positioning and self-Help Assessment” (ALPHA) sign in a predominantly stroke population. This sign was developed from the observation that some stroke patients guard the affected limb. Even mild deficits seem to have minimally supportive micro-gestures of one hand touching or lightly supporting the affected limb. Methods: IRB approval was obtained to review available videos of 63 stroke and non-stroke patients. Observers were instructed to only watch the initial 30 seconds of each video and focus on the limbs. The remaining video, and all the audio, were withheld. Videos were independently scored for the ALPHA sign. A composite score, defined as positive if &gt;/= 50% of examiners reported its presence, was assigned. Scores were compared to true diagnosis (stroke/ CNS lesion was positive if there was a scorable deficit and imaging positive CNS lesion). Sensitivity analyses were performed. Results: Of the original 69 videos, 37 were from the outpatient setting (21 with stroke or other CNS lesions; 16 neurologically intact) and 26 were from the inpatient setting (20 with stroke or other CNS lesions; 6 neurologically intact). The ALPHA sign had a specificity of 86.4% and positive predictive value of 89.7%. Sensitivity was 63.4% and negative predictive value was 55.9%. Conclusions: High specificity and positive predictive value of the ALPHA sign were found suggesting that the recognition of subtle supportive gestures may help in early identification of CNS lesions during a stroke code. As expected, the sign had a lower sensitivity as the cohort was not limited to motor-only deficits. Further assessments in other stroke types, assessing a larger cohort and more examiners of various training level, are planned.
