Geriatric nutritional risk index predicts all-cause mortality in the oldest-old patients with acute coronary syndrome: A 10-year cohort study

Background and objective Nutritional status assessment in acute coronary syndrome (ACS) patients has been neglected for a long time. The geriatric nutritional risk index (GNRI) is a sensitive indicator for assessing the nutritional status of the elderly. This study aims to explore the association between GNRI and all-cause mortality in the oldest-old patients with ACS. Methods The patients who met the inclusion criteria were consecutively enrolled from January 2006 to December 2012. Clinical data were collected on admission, and all subjects were followed after being discharged. The nutritional status was evaluated using GNRI. The relationship between GNRI and all-cause mortality was assessed by using different analyses. Results A total of 662 patients with a mean age of 81.87 ± 2.14 years old were included in our study, and followed (median: 63 months, IQR 51–71). Patients whose GNRI ≤ 98 were reported as at risk of malnutrition (31.11%, n = 206). In multivariable analysis, we found that for each SD increase in GNRI, the risk of all-cause mortality lowered by 23%, and the HR for GNRI ≤ 98 was 1.39 (95% CI 1.04–1.86). After stratifying patients into three groups by tertiles of GNRI, we found that the HRs for tertile 2 and tertile 3 were 1.49 (95% CI 1.02–2.19) and 1.74 (95% CI 1.22–2.50), respectively. The trend test revealed a dose–response relationship between GNRI and all-cause mortality in the oldest-old with ACS. Lastly, in subgroup analyses, we found a reliable association between GNRI and all-cause mortality. Conclusion Malnutrition is common in the oldest-old patients with ACS, and GNRI could predict their long-term all-cause mortality in a dose-dependent manner. GNRI may be a prospective index for risk-stratification and secondary-prevention in the oldest-old patients with ACS.
Voices from the Patients: A Qualitative Study of the Integration of Tuberculosis, Human Immunodeficiency Virus and Primary Healthcare Services in O.R. Tambo District, Eastern Cape, South Africa

Tuberculosis (TB), a disease of poverty and inequality, is a leading cause of severe illness and death among people with human immunodeficiency virus (HIV). In South Africa, both TB and HIV epidemics have been closely related and persistent, posing a significant burden for healthcare provision. Studies have observed that TB-HIV integration reduces mortality. The operational implementation of integrated services is still challenging. This study aimed to describe patients’ perceptions on barriers to scaling up of TB-HIV integration services at selected health facilities (study sites) in Oliver Reginald (O.R) Tambo Municipality, Eastern Cape province, South Africa. We purposely recruited twenty-nine (29) patients accessing TB and HIV services at the study sites. Data were analyzed using qualitative content analysis and presented as emerging themes. Barriers identified included a lack of health education about TB and HIV; an inadequate counselling for HIV and the antiretroviral drugs (ARVs); and poor quality of services provided by the healthcare facilities. These findings suggest that the O.R. Tambo district needs to strengthen its TB-HIV integration immediately.
The relationship between work practice environment and work engagement among nurses: The multiple mediation of basic psychological needs and organizational commitment a cross-sectional survey

Background Previous researchers have demonstrated that the work practice environment influences nurses' engagement; however, few studies have explored the mechanisms that explain the links between them. Objectives To examine whether basic psychological needs and organizational commitment mediate the relationship between the work practice environment and work engagement. Methods A cross-sectional survey was conducted with a sample of 893 nurses from 14 cities in Sichuan Province of China between November 2021 and December 2021. Data were collected online using the Chinese version of the Practice Environment Scale of the Nursing Work Index, Basic Needs Satisfaction in General Scale, Organizational Commitment Scale, and Utrecht Work Engagement Scale. The Pearson correlation analysis and multiple mediation model were used to analyze the data. Results The Pearson correlation analysis showed that work practice environment, basic psychological needs, and organizational commitment were positively associated with work engagement. The positive relationship between work practice environment and work engagement was mediated by basic psychological needs and organizational commitment [B = 0.505, SE = 0.032, 95% CI (0.442, 0.566)]. Conclusions The study substantially contributes to the existing knowledge by revealing the mechanisms of fostering work engagement among nurses and explaining why the work practice environment influences work engagement.
Optical pump-probe measurements of sound velocity and thermal conductivity of hydrogenated amorphous carbon films

In this paper, we report the measurements of the thermal conductivity and longitudinal sound velocity of four types of hydrogenated amorphous carbon films. The measurements were made with an ultrafast optical pump-probe apparatus. The films were deposited at various temperatures by plasma enhanced chemical vapor deposition. The films are of a low density (1.0–1.4 g cm−3) and are found to have sound velocities that range from as low as 3 km/s to as high as 10 km/s. The thermal conductivities are between 0.6 and 1.4 W/mK which are low compared to amorphous SiO2 but are larger than published measurements of thin films of similar composition and density by a factor of 2–3.
A novel myeloid cell marker genes related signature can indicate immune infiltration and predict prognosis of hepatocellular carcinoma: Integrated analysis of bulk and single-cell RNA sequencing

Myeloid cells are physiologically related to innate immunity and inflammation. Tumor-associated myeloid cells gained increasing interest because of their critical roles in tumor progression and anticancer immune responses in human malignancies. However, the associations between tumor-associated myeloid cell-related genes and hepatocellular carcinoma have yet to be revealed. Here, through the integrating analysis of bulk and single-cell RNA (scRNA) sequencing of public HCC samples, we developed a gene signature to investigate the role of HCC-specific myeloid signature genes in HCC patients. We firstly defined 317 myeloid cell marker genes through analyzing scRNA data of HCC from the GEO dataset. After selecting the differentially expressed genes, eleven genes were also proved prognostic. Then we built a gene signature from the TCGA cohort and verified further with the ICGC dataset by applying the LASSO Cox method. An eight genes signature (FABP5, C15orf48, PABPC1, TUBA1B, AKR1C3, NQO1, AKR1B10, SPP1) was achieved finally. Patients in the high risk group correlated with higher tumor stages and poor survival than those in the low-risk group. The risk score was proved to be an independent risk factor for prognosis. The high risk group had higher infiltrations of dendritic cells, macrophages and Tregs. And the APC co-inhibition, T cell co-inhibition pathways were also activated. Besides, the risk score positively correlated with multidrug resistance proteins. In conclusion, our myeloid cell marker genes related signature can predict patients’ survival and may also indicate the levels of immune infiltration and drug resistance.
Estimating the Speed of Light from Earth-Moon Communication

During the Moon landing of Apollo 16 on April 21, 1972, a spoken message from Earth is heard returning to Earth roughly 2.7 s later. The signal traveled from Earth to the Moon, from the earphone to the microphone of astronaut John Young's space helmet, and back to Earth. A recording of this “space echo,” available at Ref. 1, enables a simple approximate determination of the speed of light.
Road classification using 3D LiDAR sensor on vehicle

Road classification is essential in outdoor vehicle perception systems to evaluate driving scenarios. A light detection and ranging (LiDAR) sensor can provide accurate measurements of an environment composed of range, intensity, and angular information. This study proposes a weakly supervised learning algorithm for classifying road surface types based on laser measurements. The proposed algorithm first separates the laser points on the road surface based on the angular structure of the initial range measures obtained using 3D LiDAR in a noniterative manner. Then, a physical-data-driven model that represents the retroreflective nature of the different surface types is abstracted from the intensity measures and their factors. The linear regression parameters of the model are employed as feature descriptions of the road surface. The K-means method is used to classify the different road types. The learning process requires weak supervision at the training centroid stage and is robust to new road types. The classification performance was evaluated in different outdoor scenarios, and the classification accuracies exceeded 98%. The proposed algorithm outperforms similar existing methods, performs at the same frequency as that of LiDAR, and can be implemented in real time.
ON GALOIS SUBRINGS OF A FULL RING OF LINEAR TRANSFORMATIONS

Although several authors, including Dieudonne [1], Hochschild [3], Nakayama [5], Rosenberg and Zelinsky [9], and Jacobson [4], have worked on the Galois theory of simple rings with chain conditions, much of their work is concerned with 1-1 correspondences between groups of automorphisms of a simple ring and Galois subrings. Very little, however, has been done towards classifying those subrings of a simple ring which are Galois. Jacobson [4] gives a condition due to Nakayama for a weakly Galois completely reducible subring to be Galois. In this paper we give a sufficient condition for a non-necessarily completely reducible weakly Galois subring to be Galois. Our result overlaps Nakayama's but does not properly contain his. Throughout this paper we shall use the following notations: A, a division ring finite dimensional over its center r, rP 4GF(2); M, a finitely generated A-module; L = Hom,(M, M); R, a subring of L containing r. We assume that M as a module over any ring considered is a left-module. Since M is a finite dimensional vector space over A, it is also a finite dimensional vector space over r. Thus Homr(M, M) can be regarded in the usual way as a finitely generated algebra over r. And since the rings R, sA, r, L, and AR are contained in Homr(M, M), they are all finite dimensional over P and thus all these rings satisfy all the chain conditions and M is a finitely generated module over each of them.
Pluronic® F127 Hydrogel Containing Silver Nanoparticles in Skin Burn Regeneration: An Experimental Approach from Fundamental to Translational Research

Presently, skin burns are considered one of the main public health problems and lack therapeutic options. In recent years, silver nanoparticles (AgNPs) have been widely studied, playing an increasingly important role in wound healing due to their antibacterial activity. This work is focused on the production and characterization of AgNPs loaded in a Pluronic® F127 hydrogel, as well as assessing its antimicrobial and wound-healing potential. Pluronic® F127 has been extensively explored for therapeutic applications mainly due to its appealing properties. The developed AgNPs had an average size of 48.04 ± 14.87 nm (when prepared by method C) and a negative surface charge. Macroscopically, the AgNPs solution presented a translucent yellow coloration with a characteristic absorption peak at 407 nm. Microscopically, the AgNPs presented a multiform morphology with small sizes (~50 nm). Skin permeation studies revealed that no AgNPs permeated the skin after 24 h. AgNPs further demonstrated antimicrobial activity against different bacterial species predominant in burns. A chemical burn model was developed to perform preliminary in vivo assays and the results showed that the performance of the developed AgNPs loaded in hydrogel, with smaller silver dose, was comparable with a commercial silver cream using higher doses. In conclusion, hydrogel-loaded AgNPs is potentially an important resource in the treatment of skin burns due to their proven efficacy by topical administration.
Estimating boreal forest species type with airborne polarimetric synthetic aperture radar

We have applied a non-parametric classifier (k nearest neighbour) to two calibrated orthogonal passes of airborne polarimetric synthetic aperture radar (POLSAR) image data over boreal forest for the purpose of discriminating canopy tree species of predefined stands. We found that a single classifier based on a single feature space (i.e. one set of POLSAR variables for all species) was less accurate than a hierarchical two-stage classifier that used different POLSAR variables for each species. We designed a two-stage classifier that first grouped stands into broad classes: pine, spruce and deciduous, and then classified each sample within the broad classes into individual species. We found that the most effective feature spaces had two or three dimensions. The two-stage classifier attained overall accuracies of between 60% and 75%. We provide a first use of an equivalency test applied to remote-sensing classification. We use Lloyd's test of equivalency to find equivalent classifiers and thus infer informative POLSAR variables. The POLSAR variables that were most informative varied between the two passes and between the various elements of the hierarchical classifier. For the initial three-class classifier the most informative POLSAR variables were the two circular polarization ratios, several of Touzi's Stokes vector variables, HHVV coherence, several texture measures such as the variance of several scattering coefficients and the order parameter of the K-distribution and characteristics of the polarization signature pedestal. These results demonstrate that C-band POLSAR has great potential for mapping boreal forest cover either on its own or in concert with other geospatial data.
Modelling of heat and fluid flow during the evaporation of volatile drops on hot substrates

In this paper a review on the convective patterns observed during sessile droplets evaporation is performed. A model describing a pinned evaporating drop is introduced; the numerical resolution of the model allows the description of heat and fluid flow within the drop. The role of humidity in the gas phase is investigated, by taking into account the vapour diffusion process. It is shown that the change in substrate temperature has the most important effect on the evaporation rate. The results show that surface tension in comparison to the gravity convection is more accurate in describing evaporation of small droplets.
Citizens’ Satisfaction With Local Government Service Delivery Performance in Bangladesh: Does Citizens’ Confidence Matter?

The purpose of this study is to explain the relationship between perceived quality of local service delivery performance and citizens’ satisfaction through confidence at urban local government level in Bangladesh. A mediation model was framed to test the indirect relationship between perceived quality of service delivery performance and citizens’ satisfaction. Data was collected through a survey during April 2014 – June 2014. The survey included ten Paurashavas (Municipality) while the participants (n = 706) were selected based on gender ratio and Ward of the Paurashavas. Multilevel path analysis was conducted using MPLUS 8 to examine the mediation model. The results showed that citizens’ confidence partially mediates the relationship between perceived quality of service delivery performance and citizens’ satisfaction.

The Fundamental Group of the Complement of the Complexification of a Real Arrangement of Hyperplanes

Let A be an arrangement of hyperplanes (i.e., a finite set of 1-codimension vector subspaces) in Rd. We say that the linear ordering of the hyperplanes A,H1? H2? ···? Hn, is ashellabilityorder of A, if there is an oriented affine linelcrossing the hyperplanes of A on the given linear order. The intersection latticeL(A) is the set of all intersections of the hyperplanes of A partially ordered by reversed inclusion. Set M(Ac)? Cd\? {H? C:H? A}. We will prove:Suppose that there are shellability orders H1? H2? ···? Hnand H? 1? H? 2? ···? H? n, respectively, ofAandA? ,such that the bijective map Hi? H? i, i? n]determines an isomorphism of the intersection lattices L(A)and L(A? ). Then the fundamental groups? 1(M(Ac))and? 1(M(A? c)) are isomorphic.
Impact of Resilience and Coping Strategy on Post-Traumatic Symptoms Among Muslim University Students

This study examined the association between resilience and coping strategies on post-traumatic stress symptoms in Muslim university students. The study used a cross-sectional design and gathered data from 1157 participants using four questionnaires. The results showed that higher levels of resilience were related to higher coping strategies and lessened post-traumatic stress symptoms. In comparison, higher levels of coping strategies were correlated with lower levels of post-traumatic stress symptoms. In addition, the regression analysis revealed that resilience and coping strategies were significant predictors of post-traumatic stress symptoms, with resilience predicting lower levels of post-traumatic stress symptoms and coping strategies predicting higher levels. These findings suggest that interventions focusing on improving resilience and coping strategies may help reduce post-traumatic stress symptoms among Muslim university students. However, further research is needed to confirm these findings and examine this association's underlying mechanisms.
The impact of foreign trade liberalization on Albania’s economic growth: An econometrical approach

The relationship between economic growth and foreign trade was put in focus by many economists when foreign trade developed. The case of Free Trade is always associated with significant positive effects on foreign trade and economic growth. This paper explains the relationship between trade liberalization, foreign trade, and economic growth in Albania using annual economic development data for 1994-2019. This study is based on hypotheses for Causality Testing concerning the cointegration between GDP and foreign trade, trade liberalization and GDP, and GDP and exports in Albania. The ordinary least squares (OLS) model has been used. Empirical results for the Albanian case show that trade liberalization has a positive relationship with economic growth, exports, and imports. However, the multiple regression proved that GDP, Openness Index, FDI, and remittances positively impacted trade volume growth.
Valence and core photoemission in M@C60 (M = Be, Mg, Ca)

The B-spline density functional method for the electronic continuum is employed to calculate the cross section and the asymmetry parameter profiles of valence and core photoionization in M@C60 (M = Be, Mg and Ca). For the valence photoionization significant differences are identified through the series and oscillations similar to those observed in the HOMO/HOMO-1 ratio in C60 have been calculated for Ca@C60. Core M 1s and Ca 2p ionizations are studied with the help of the `dipole prepared' continuum orbitals, which allows the identification of the leading mechanisms which give rise to the characteristic sharp and intense shape resonances, typical of these compounds.
The evolution of electron overdensities in magnetic fields

When a neutral gas impinges on a stationary magnetized plasma an enhancement in the ionization rate occurs when the neutrals exceed a threshold velocity. This is commonly known as the critical ionization velocity effect. This process has two distinct timescales: an ion–neutral collision time and electron acceleration time. We investigate the energization of an ensemble of electrons by their self-electric field in an applied magnetic field. The evolution of the electrons is simulated under different magnetic field and density conditions. It is found that electrons can be accelerated to speeds capable of electron impact ionization for certain conditions. In the magnetically dominated case the energy distribution of the excited electrons shows that typically 1% of the electron population can exceed the initial electrostatic potential associated with the unbalanced ensemble of electrons.
Effects of Dried Tomato, Apple and Grape Pulps on the Performance, and Egg Quality of Laying Hens

The purpose of this study was to determine the dietary effects of fruit pulps (dried tomato, apple and grape) on the performance and egg quality characteristics of laying hens. In this trial, 196 Lohmann sandy layers 25 weeks of age were distributed into four groups with seven replicates for 9 weeks. Trial groups fed following diets, control group basal diet (no additive), 4 % dried tomato pulp, 4% apple pulp and 2.5% grape pulp. Feed conversion rate was not affected by any addition of fruit pulps throughout the trial. The dietary inclusion of dried tomato pulp increased feed consumption, egg weight and egg production and decreased egg yolk malondialdehyde (MDA) levels on day of 1 compared to the control. Egg yolk MDA level was decreased with the addition of 4% tomato and apple pulp to the diet, but increased with the addition of 2.5% grape pulp to the diet on the day of 28. Moreover, the addition of dried tomato pulp to the basal diet significantly increased egg weight and egg yolk yellow color (a). As a result, this study provides evidence that adding up to 4% tomato pulp to diets may be used without adverse effects on laying hens’ productivity and may improve egg quality characteristics by decreasing MDA levels in the yolk.
Justice-Involved Youths’ Perceptions of Placement Instability and Adjustment Related Outcomes

ABSTRACT Unique challenges associated with dual involvement in the child welfare and juvenile justice systems are well documented. However, there is a paucity of research focusing on the out-of-home placement experiences of youth involved in the justice system and implications for relevant outcomes. The current study examined out-of-home placement experiences and placement instability of justice-involved youth and how these experiences relate to relevant outcomes for youth involved with multiple service systems: attitudes toward seeking help, intolerance of uncertainty, and perceived containment. Participants included youth detained at two juvenile detention centers (n = 225; 71.1% male; M age = 15.50). Self-report measures were read by research assistants who recorded the youths’ responses. Results revealed that over 50% of detained youth had been removed from their parents’ custody, and of these youth, nearly 60% reported experiencing three or more placement changes. Attitudes toward seeking help and intolerance of uncertainty in youth who experienced out-of-home placement were not significantly different than in youth who did not. However, youth who had experienced out-of-home placement exhibited significantly lower perceived containment scores. These findings suggest that placement instability is common among detained youth and may be meaningfully related to youth’s feelings about the ability of authorities to control them.
