Quantifying spatial scale of positive and negative terrains pattern at watershed-scale:Case in soil and water conservation region on Loess Plateau

The positive and negative terrains(P-N terrains) widely distributed across China's Loess Plateau constitute the dual structure characteristic of loess landforms. Analysis of loess P-N terrains at the watershed scale can serve to elucidate the structural characteristics and spatial patterns of P-N terrains, which benefits a better understanding of watershed evolution and suitable scales for loess landform research. The Two-Term Local Quadrat Variance Analysis(TTLQV) is calculated as the average of the square of the difference between the block totals of all possible adjacent pairs of block size, which can be used to detect both the scale and the intensity of landscape patches(e.g., plant/animal communities and gully networks). In this study, we determined the latitudinal and longitudinal spatial scale of P-N terrain patterns within 104 uniformly distributed watersheds in our target soil and water conservation region. The results showed that TTLQV is very effective for examining the scale of P-N terrain patterns. There were apparently three types of P-N terrain pattern in latitudinal direction(i.e., Loess Tableland type, Loess Hill type, and Transitional Form between Sand and Loess type), whereas there were both lower and higher values for P-N terrain pattern scales in all loess landforms in the longitudinal direction. The P-N terrain pattern alsoclearly presented anisotropy, suggesting that gully networks in the main direction were well-developed while others were relatively undeveloped. In addition, the relationships between the first scales and controlling factors(i.e., gully density, nibble degree, watershed area, mean watershed slope, NDVI, precipitation, loess thickness, and loess landforms) revealed that the first scales are primarily controlled by watershed area and loess landforms. This may indicate that the current spatial pattern of P-N terrains is characterized by internal force. In selecting suitable study areas in China' Loess Plateau, it is crucial to understand four control variables: the spatial scale of the P-N terrain pattern, the watershed area, the main direction of the watershed, and the loess landforms.

Correlation analyse between thyroid hormone levels and severity of schizophrenia symptoms

BACKGROUND The imbalance of hormone levels in the body is closely related to the occurrence and progression of schizophrenia,especially thyroid hormones.AIM To study the relationship between triiodothyronine(T3),thyroxine(T4),free T3(FT3),free T4(FT4),thyroid stimulating hormone(TSH)and schizophrenia.METHODS In this study,100 schizophrenia patients were selected from our hospital between April 2022 and April 2024.Their clinical data were analyzed retrospectively.Based on the Positive and Negative Syndrome Scale(PANSS)score,patients were divided into mild(1-3 points,n=39),moderate(4 points,n=45),and severe groups(5-7 points,n=16).Additionally,55 healthy individuals served as a control group.Venous blood samples were collected to measure T3,T4,FT3,FT4,TSH,and cortisol concentrations,analyzing their relationship with PANSS scores.RESULTS The serum levels of T3,FT3,FT4,TSH and cortisol in the schizophrenia group were lower than those in the control group(P<0.05).With the increase of the severity of the disease,the concentrations of T3 and T4 decreased,while the con-centrations of TSH and cortisol increased(P<0.05).The concentrations of TSH and cortisol were positively correlated with the PANSS score,while T3 and T4 were negatively correlated with the PANSS score(P<0.05).The receiver ope-rating characteristic curve results showed that T3,T4,TSH,and cortisol had good efficacy in the diagnosis of schizophrenia.Logistic results showed that decreased T3 level,decreased T4 level,decreased TSH level and increased cortisol level may be independent risk factors for schizophrenia.CONCLUSION Thyroid hormone levels are associated with the severity of schizophrenia symptoms,which can provide new solutions for the diagnosis and treatment of schizophrenia.

A New Interpretation of the Higgs Vacuum Potential Energy Based on a Planckion Composite Model for the Higgs

We present a new interpretation of the Higgs field as a composite particle made up of a positive, with, a negative mass Planck particle. According to the Winterberg hypothesis, space, i.e., the vacuum, consists of both positive and negative physical massive particles, which he called planckions, interacting through strong superfluid forces. In our composite model for the Higgs boson, there is an intrinsic length scale associated with the vacuum, different from the one introduced by Winterberg, where, when the vacuum is in a perfectly balanced state, the number density of positive Planck particles equals the number density of negative Planck particles. Due to the mass compensating effect, the vacuum thus appears massless, chargeless, without pressure, energy density, or entropy. However, a situation can arise where there is an effective mass density imbalance due to the two species of Planck particle not matching in terms of populations, within their respective excited energy states. This does not require the physical addition or removal of either positive or negative Planck particles, within a given region of space, as originally thought. Ordinary matter, dark matter, and dark energy can thus be given a new interpretation as residual vacuum energies within the context of a greater vacuum, where the populations of the positive and negative energy states exactly balance. In the present epoch, it is estimated that the dark energy number density imbalance amounts to, , per cubic meter, when cosmic distance scales in excess of, 100 Mpc, are considered. Compared to a strictly balanced vacuum, where we estimate that the positive, and the negative Planck number density, is of the order, 7.85E54 particles per cubic meter, the above is a very small perturbation. This slight imbalance, we argue, would dramatically alleviate, if not altogether eliminate, the long standing cosmological constant problem.

Effect of psychological nursing interventions on effectiveness and quality of life in schizophrenia patients receiving modified electroconvulsive therapy

BACKGROUND Schizophrenia is a common and severe mental disorder characterized by severe thought disturbances,hallucinations,delusions,and emotional instability.For some patients,conventional treatment methods may not effectively alleviate symptoms,necessitating the use of alternative therapeutic approaches.Modified electroconvulsive therapy(MECT)is an effective treatment modality for schizophrenia,inducing anti-depressive and antipsychotic effects through the stimulation of brain electrical activity.AIM To explore the impact of psychological nursing intervention(PNI)before and after MECT on the efficacy and quality of life of patients with schizophrenia.METHODS Eighty patients with schizophrenia who received MECT treatment from 2021 to 2023 were randomly divided into two groups:The intervention group(n=40)and the control group(n=40).The intervention group received PNI before and after MECT,while the control group received routine nursing care.The efficacy of MECT was evaluated by the Positive and Negative Syndrome Scale(PANSS)and the Clinical Global Impression Scale(CGI)before and after the treatment.The quality of life was assessed by the Short Form 36 Health Survey(SF-36)after the treatment.RESUITS The intervention group had significantly lower scores of PANSS and CGI than the control group after the treatment(P<0.05).The intervention group also had significantly higher scores of SF-36 than the control group in all domains except physical functioning(P<0.05).CONCLUSION PNI before and after MECT can improve the efficacy and quality of life of patients with schizophrenia.It is suggested that nurses should provide individualized and comprehensive psychological care for patients undergoing MECT to enhance their recovery and well-being.

Evaluation of paliperidone on social function in patients with chronic schizophrenia

Background The impairment of social function is widespread in the patients with chronic schizophrenia, which seriously affects family, life and work conditions.Aims The main purpose of this study was to investigate the efficacy of paliperidone in the treatment of social function in chronic schizophrenia.Methods A total of 81 patients who met the standard criteria for schizophrenia and long-term hospitalised inpatients were randomly divided into the treatment group and normal control group following a 1-year prospective follow-up study. The reatment group(41 cases) used paliperidone extended-release tablets for reducing dosage, as appropriate, based on the original treatment strategy; and the control group(40 cases) used the former drugs. All patients were assessed using the Positive and Negative Symptom Scales(PANSS), and the Treatment Emergent Symptom Scale(TESS) was used to assess adverse drug reactions. The Hospitalised Psychiatric Patients' Social Functions Rating Scale(SSPI) was used to assess social function of participants before and after 8 weeks, 6 months and 1 year of treatment.Results At baseline there were no significant differences between the two groups in age, duration of illness, educational background and dosage of antipsychotic drugs(converted into chlorpromazine equivalency). There was statistically significant difference in PANSS positive symptoms by interaction effect(Fgroup×time=18.24, df=3237, p<0.001) and time effect(Ftime=21.66, df=3, p<0.01) and the difference in PANSS positive symptoms by grouping effect(Fgroup=0.68, df=1, p=0.41) was not statistically significant. The difference of grouping effect of PANSS negative symptoms(Fgroup=9.93, df=1, p=0.002), time effect(Ftime=279.15, df=3, p<0.001) and interaction effect(Fgroup×time=279.15, df=3237, p<0.001) were statistically significant. There were statistically significant differences in the grouping effect(Fgroup=6.59, df=1, p=0.012), time effect(Ftime=152.97, df=3, p<0.001) and interaction effect(Fgroup×time=148.82, df=3237, p<0.001) of PANSS general pathological symptoms, the same as the total score of the PANSS, which showed large differences in grouping effect(Fgroup=7.04, df=1, p=0.001), time effect(Ftime=210.78, df=3, p<0.001) and interaction effect(Fgroup×time=205.20, df=3237, p<0.01). We found in the total SSPI score, grouping effect(Fgroup=31.70, df=1, p<0.001), time effect(Ftime=161.84, df=3, p<0.001) and interaction effect(Fgroup×time=132.74, df=3237, p<0.001) were demonstrated to be significantly different. Even though adverse reactionsoccurred 7 times in the treatment group and 44 times in the control group based on the Treatment Emergent Symptom Scale(TESS), incidence rate was significantly lower than that of the control group(χ2=18.854, p<0.001).Conclusion Paliperidone can safely and effectively improve negative symptoms and social function in patients with chronic schizophrenia.

Study on Computational Properties of Several VerticalGrids with a Nonhydrostatic Model in Comparisonto Analytical Solutions

Starting from nonhydrostatic anelastic equations a comparative investigation is performed of inertial-gravitational wave hundreds, tens and a few of kilometers in horizontal wavelength, which are ex amined on vertical grids available at present from the perspectives of frequency, vertical component of group velocity and the inappropriate range for a positive vertical component emerging, with the findings compared to analytical solutions. Evidence suggests that grids C’P and LZ are suitable for the study of the wave at the mentioned horizontal scales and the counterparts L and LY (LTS and CPTS) are applicable on ly to the horizontal scales of more (less) than lens of kilometers.

Objective:The efficacy and occurrence of adverse reactions of prescriptions containing phlegm-resolving Chinese medicine combined with risperidone in the treatment of schizophrenia were retrospectively studied by means of meta-analysis.Methods:A variety of different Chinese and English databases were searched from January 1,2000 to May 1,2020.Review Manager 5.3 software was used to evaluate the methodological quality of the included studies.The positive and negative symptom scale(PANSS)was used as the evaluation standard to analyze the total scores,positive scores,negative scores and general psychopathological scores,clinical efficacy and safety of prescriptions containing phlegmresolving Chinese medicine combined with risperidone of schizophrenia.The heterogeneity test and sensitivity analysis were also carried out by Review Manager 5.3,and the potential publication bias was analyzed by"funnel plot".Results:A total of 1515 patients were included in 15 studies.Compared with control group of risperidone alone,the total PANSS scale score,positive symptom score,negative symptom score and general psychopathological score of the treatment group of phlegm-resolving Chinese medicine combined with risperidone were all lower than those of the control group(P=0.01,MD=-6.35,95%CI[-11.29,-1.40]),(P=0.04,MD=-1.42,95%CI[-2.74,-0.09]),(P<0.01,MD=-2.16,95%CI[-3.41,-0.91]),and(P<0.01,MD=-3.80,95%CI[-6.37,-1.24]),the clinical efficacy of phlegm-resolving Chinese medicine combined with risperidone treatment group on schizophrenia was better than that of the control group[P<0.01,RR=1.09,95%CI(1.05-1.13)].The incidence of adverse reactions was reduced(P=0.02,RR=0.56,95%CI[0.34-0.93]).Conclusion:The combination of prescriptions containing phlegm-resolving Chinese medicine and risperidone can effectively improve the efficacy of patients with schizophrenia and reduce the occurrence of adverse drug reactions compared with risperidone alone.

On the Cosmic Evolution of the Quantum Vacuum Using Two Variable G Models and Winterberg’s Thesis

We work within a Winterberg framework where space, i.e., the vacuum, consists of a two component superfluid/super-solid made up of a vast assembly (sea) of positive and negative mass Planck particles, called planckions. These material particles interact indirectly, and have very strong restoring forces keeping them a finite distance apart from each other within their respective species. Because of their mass compensating effect, the vacuum appears massless, charge-less, without pressure, net energy density or entropy. In addition, we consider two varying G models, where G, is Newton’s constant, and G-1, increases with an increase in cosmological time. We argue that there are at least two competing models for the quantum vacuum within such a framework. The first follows a strict extension of Winterberg’s model. This leads to nonsensible results, if G increases, going back in cosmological time, as the length scale inherent in such a model will not scale properly. The second model introduces a different length scale, which does scale properly, but keeps the mass of the Planck particle as, ± the Planck mass. Moreover we establish a connection between ordinary matter, dark matter, and dark energy, where all three mass densities within the Friedman equation must be interpreted as residual vacuum energies, which only surface, once aggregate matter has formed, at relatively low CMB temperatures. The symmetry of the vacuum will be shown to be broken, because of the different scaling laws, beginning with the formation of elementary particles. Much like waves on an ocean where positive and negative planckion mass densities effectively cancel each other out and form a zero vacuum energy density/zero vacuum pressure surface, these positive mass densities are very small perturbations (anomalies) about the mean. This greatly alleviates, i.e., minimizes the cosmological constant problem, a long standing problem associated with the vacuum.
