Searching for extremal PPT entangled states
We study extremality in various sets of states that have positive partial
transposes. One of the tools we use for this purpose is the recently formulated
criterion allowing to judge if a given state is extremal in the set of PPT
states. First we investigate qubit--ququart states and show that the only
candidates for extremal PPT entangled states (PPTES) have ranks of the state
and its partial transposition (5,5) or (5,6) (equivalently (6,5)). Then,
examples of extremal states of (5,5) type and the so--called edge states of
type (5,6) are provided. We also make an attempt to explore the set of PPT
states with ranks (5,6). Finally, we discuss what are the possible
configurations of ranks of density matrices and their respective partial
transposition in general three-qubit and four-qubit symmetric states for which
there may exist extremal entangled PPT states. For instance in the first case
we show that the only possibilities are (4,4,4) and (4,4,5).Comment: 12 pages, 2 figures, revised version due to the partial overlap with

https://orcid.org/0000-0002-8796-0420This cross-sectional study evaluated the validity of three alternative methods compared to the gold standard 24-h urine collection for estimating dietary sodium intake, a modifiable risk factor for hypertension, among middle-aged and older adults with elevated blood pressure. These included spot urine collection (using Kawasaki, Tanaka, and INTERSALT equations), 24-h dietary recall, and food frequency questionnaire responses, compared to 24-h urine collection in a subset of 65 participants (aged 50–75 years, 58.5% women, 61.6% hypertensive) from the DePEC-Nutrition trial. The validity of the methods was assessed using bias, the Spearman correlation coefficient (SCC), the intraclass correlation coefficient (ICC), and Bland–Altman analysis. Among the alternative methods, spot urine collection using the Kawasaki equation showed the strongest correlation (SCC 0.238; ICC 0.119, 95% CI −0.079 to 0.323), but it exhibited a significant bias (1414 mg/day, p-value < 0.001) relative to 24-h urine collection. Conversely, dietary surveys had a smaller bias but wider limits of agreement. These findings underscore the complexities of accurately estimating dietary sodium intake using spot urine collection or dietary surveys in this specific population, suggesting that a combination or the refinement of existing methodologies might improve accuracy. Further research with larger samples is necessary to develop more reliable methods for assessing sodium intake in this high-risk group.10pubpub1
Modified Nanocellulose-Based Adsorbent from Sago Waste for Diclofenac Removal
A nanocellulose-based adsorbent was successfully synthesized via a hydrothermal process. It was characterized by X-ray diffraction, Fourier Transform Infrared Spectroscopy, Field Emission Electron Microscopy and Brunauer–Emmett–Teller surface area analysis. Photocatalysis has the best
potential to replace the conventional wastewater treatment technology through the photodegradation of organic contaminants. This study focuses on the preparation of a photocatalytic adsorbent of nanocellulose prepared from sago waste for the removal of diclofenac from industrial wastewater. Its photocatalytic activity was evaluated through the degradation of diclofenac (100 mg/L) under
ultraviolet (UV) light. The effect of different loadings of TiO2 and kinetics on the photocatalytic
activity was investigated. To study its removal, the experiments were carried out under UV light
with different contact times ranging from 30 to 120 min at room temperature. The maximum removal
percentage was found to be 57.5% for 200 �L of TiO2, and this increased up to 82.4% for 800 �L of
TiO2. The maximum removal capacity was found to be 13.3 mg/g. The kinetics was well fitted with
“pseudo-first order model” (PSO). Kinetic analysis using the PSO model at 100 ppm of diclofenac
sodium gave a value of equilibrium adsorption capacity, qe of 13.52 mg/g. The adsorption kinetics
gave a value of calculated equilibrium adsorption capacity, qe of 13.52 mg/g using different nonlinear
regression plots. It obeyed a pseudo-first-order reaction with the lowest AICc, RSME values of 0.56 and 0.53 and the highest correlation coefficient, R2, of 0.99. Three kinetics models were fitted for the current adsorption kinetics data, and their suitability was inferred as the following:
pseudo-first-order > pseudo-second-order > Langmuir–Hinshelwood
Determinants of active aging and quality of life among older adults: systematic review
IntroductionPopulation demography across the globe shows an increasing trend in the aging population due to better healthcare, improved nutrition, advanced health-related technology, and decreased fertility rate. Despite these advancements, there remains a knowledge gap in understanding the association between active aging determinants and quality of life (QoL) among older adults, particularly within diverse cultural contexts, which has not been adequately explored in previous research. Therefore, understanding the association between active aging determinants and QoL can help policymakers plan early interventions or programs to assist future older adults in both aging actively and optimizing their quality of life (QoL), as these two factors have a bidirectional relationship.ObjectiveThis study aimed to review evidence regarding the association between active aging and quality of life (QoL) among older adults and to determine the most widely used study designs and measurement instruments in studies conducted between 2000 and 2020.MethodsRelevant studies were identified by a systematic search of four electronic databases and cross-reference lists. Original studies examining the association between active aging and QoL in individuals aged 60 years or older were considered. The quality of the included studies and the direction and consistency of the association between active aging and QoL were assessed.ResultsA total of 26 studies met the inclusion criteria and were included in this systematic review. Most studies reported a positive association between active aging and QoL among older adults. Active aging had a consistent association with various QoL domains including physical environment, health and social services, social environment, economic, personal, and behavioral determinants.ConclusionActive aging had a positive and consistent association with several QoL domains among older adults, backing the notion that the better the active aging determinants, the better the QoL among older adults. Considering the broader literature, it is necessary to facilitate and encourage the active participation of older adults in physical, social, and economic activities for the maintenance and/or improvement of QoL. Identifying other possible determinants and enhancing the methods to improve those determinants may help improve the QoL among older adults
Anomalous behavior of q-averages in nonextensive statistical mechanics
A generalized definition of average, termed the q-average, is widely employed
in the field of nonextensive statistical mechanics. Recently, it has however
been pointed out that such an average value may behave unphysical under
specific deformations of probability distributions. Here, the following three
issues are discussed and clarified. Firstly, the deformations considered are
physical and may experimentally be realized. Secondly, in view of
thermostatistics, the q-average is unstable in both finite and infinite
discrete systems. Thirdly, a naive generalization of the discussion to
continuous systems misses a point, and a norm better than the -norm should
be employed for measuring the distance between two probability distributions.
Consequently, stability of the q-average is shown not to be established in all
the cases.Comment: 14 pages, no figures. Accepted for publication in J. Stat. Mech
Nutritional interventions for the prevention of cognitive impairment and dementia in developing economies in East-Asia: a systematic review and meta-analysis
Daniel Reidpath - ORCID: 0000-0002-8796-0420
https://orcid.org/0000-0002-8796-0420Dementia represents a key impending global health challenge. The aim of this systematic review was to evaluate the current evidence on nutritional interventions for the prevention of dementia in developing economies in East-Asia. Four comprehensive databases were searched from inception until January 2020: MEDLINE, Embase, PsycInfo, and Scopus. The search was restricted to randomized controlled trials [RCTs] in adult humans, assessing the effect of nutritional interventions on global and domain specific cognitive performance and dementia risk. Meta-analysis of data was conducted for each domain and sub-categorized according to the type of nutritional intervention. Twenty-four RCTs were included, of which, fifteen studies showed significant beneficial effects on cognition. Eighteen studies were included in the meta-analysis. Significant beneficial effects were found for essential fatty acids (EPA/DHA) and micronutrient supplementation on specific cognitive domains including attention and orientation, perception, verbal functions and language skills. The effect size of the interventions appeared to be greater in older subjects with cognitive impairment. Supplementation with B-vitamins and essential fatty acids may represent promising strategies to minimize age-related cognitive decline in Asian populations. Large, high-quality, long-term trials are needed to confirm these findings.This research was funded by the National Institute for Health Research (NIHR) (16/137/62 - Dementia Prevention and Enhanced Care (DePEC), Newcastle University, United Kingdom), using UK aid from the UK Government to support global health research.

Breast Cancer Screening in Semi-Rural Malaysia: Utilisation and Barriers
Daniel Reidpath - ORCID: 0000-0002-8796-0420
https://orcid.org/0000-0002-8796-0420Breast cancer (BC) is the commonest cancer in Malaysia. Delayed diagnosis is a significant cause of BC mortality in the country. Early diagnosis and screening are vital strategies in mortality reduction. This study assessed the level of utilisation and barriers for breast self-examination (BSE), clinical breast examination (CBE) and mammogram in a semi-rural population in Malaysia and compared these across the different ethnic groups. This cross-sectional study was conducted among women aged 40 years and above, embedded within a health and demographic surveillance site (HDSS) in Segamat, Malaysia. Trained data collectors collected data on screening and barriers during home visits. Study participants (n = 250) were aged 59.4 ± 10.9 years and represented Malaysia’s three major ethnic groups. Practice of regular BSE, CBE uptake (ever) and mammogram (ever) was 23.2%, 36% and 22.4%, respectively. Regular BSE practice was highest in the Malay ethnic group and least among the Chinese. Regular CBE was very low in all ethnic groups (<5%). Mammogram uptake was highest among Chinese (34.4%), followed by Indians (30.4%) and Malays (16.6%). After adjusting for other socio-demographic variables, Malay ethnicity was positively associated with regular BSE (adjusted OR = 5.26, 95% CI 2.05, 13.50) and negatively associated with having had a mammogram (adjusted OR = 0.3, 95% CI 0.15, 0.57). Lower education was negatively associated (adjusted OR = 0.36, 95% CI 0.17, 0.74) with mammogram attendance (ever). Emotional and financial barriers were the most reported types of barriers, specifically, fear of diagnosis (74.8%), cost of diagnosis (69.6%) and fear of losing a breast (66.4%). Malay women more commonly reported most barriers compared to other ethnic groups. Screening uptake was low among semi-rural women in Malaysia. Implementing culturally appropriate interventions that consider ethnic differences is crucial to empowering women to engage in BC screening initiatives in these communities.https://doi.org/10.3390/ijerph18231229318pubpub2
