Abstract

BackgroundThe course of schizophrenia is prolonged， and patients have impaired social function and significantly reduced quality of life. Drug therapy combined with psychological therapy is particularly important for improving the quality of life of patients. Brief cognitive behavioral therapy （BCBT） has been widely applied in clinical practice， but current research on BCBT focuses more on improving patients' symptoms and lacks relevant reports on improving quality of life.ObjectiveTo evaluate the efficacy and influencing factors of BCBT combined with conventional treatment on improving the quality of life in patients with schizophrenia.MethodsA total of 210 patients who met the diagnostic criteria for schizophrenia in the International Classification of Diseases （10th edition） （ICD-10） and were followed up at the outpatient department of Beijing Anding Hospital Capital Medical University from August 2011 to December 2016 were selected. Using a random number table method， patients were divided into study group and control group， with 105 cases in each group. Both groups received routine treatment， and the research group received a total of 8 BCBT sessions for 12 weeks on this basis. At the baseline period and 12 weeks of treatment， 26 weeks of follow-up and 52 weeks of follow-up， Positive and Negative Syndrome Scale （PANSS）， Personal and Social Performance Scale （PSP） and World Health Organization Quality of Life Brief （WHOQOL-BREF） were used for evaluation.ResultsThe results of repeated measures analysis of variance showed that the time point effect and interaction effect of PANSS total score were statistically significant （F=118.783， 8.083， P

Abstract

In the literature, bilocality and $n$-locality of correlation tensors (CTs) are described by integration local hidden variable models (called C-LHVMs) rather than by summation LHVMs (called D-LHVMs). Obviously, C-LHVMs are easier to be constructed than D-LHVMs, while the later are easier to be used than the former, e.g., in discussing on the topological and geometric properties of the sets of all bilocal and of all $n$-local CTs. In this context, one may ask whether the two descriptions are equivalent. In the present work, we first establish some equivalent characterizations of bilocality of a tripartite CT ${\bf{P}}=\Lbrack P(abc|xyz)\Rbrack$, implying that the two descriptions of bilocality are equivalent. As applications, we prove that all bilocal CTs with the same size form a compact path-connected set that has many star-convex subsets. Secondly, we introduce and discuss the bilocality of a tripartite probability tensor (PT) ${\bf{P}}=\Lbrack P(abc)\Rbrack$, including equivalent characterizations and properties of bilocal PTs. Lastly, we obtain corresponding results about $n$-locality of $n+1$-partite CTs ${\bf{P}}=\Lbrack P({\bf{a}}b|{\bf{x}}y)\Rbrack$ and PTs ${\bf{P}}=\Lbrack P({\bf{a}}b)\Rbrack$, respectively.

Abstract

Objective: To evaluate the efficacy and safety of Qili Qiangxin Capsule (QLQXC) combined with western medicine in patients with ischemic cardiomyopathy (ICM) comorbid with heart failure (HF) for clinical application. Methods: We searched relevant references in Chinese databases including China National Knowledge Infrastructure (CNKI), China Scientific Journal Database (VIP), Wanfang Database, and China Biology Medicine (CBM), as well as English databases including PubMed and Embase, from the foundation of the database to January 8, 2023, without language restrictions. All statistical analyses, including subgroup and sensitivity analyses, were performed using the Review Manager (version 5.4) and Stata (version 15.0). Results: QLQXC combined with western medicine significantly increased the endpoints of overall response rate (ORR) (P < 0.000 01), left ventricular ejection fraction (LVEF) (P < 0.000 01), the score of Minnesota Living with Heart Failure Questionnaire (MLHFQ) (P = 0.000 2), and 6-minute walking distance (6MWD) (P < 0.000 01), decreased left ventricular end-diastolic diameter (LVEDD) (P < 0.000 01), left ventricular end-systolic diameter (LVESD) (P = 0.03), and pro-brain natriuretic peptide (pro-BNP) (P < 0.00001), and reduced the incidence of rehospitalization (P = 0.0003) and adverse events (AEs) (P = 0.000 6) compared with those under the conventional western therapy alone. Nonetheless, no significant difference was observed in reducing the mortality between the QLQXC combined with western medicine group and the western medicine group (P = 0.30). Conclusion: The combination therapy of QLQXC with western medicine can potentiate cardiac function and raise the quality of life in patients with ICM comorbid with HF.

Abstract

Since masking of quantum information was introduced by Modi et al. in [PRL 120, 230501 (2018)], many discussions on this topic have been published. In this paper, we consider relationship between quantum multipartite maskers (QMMs) and quantum error-correcting codes (QECCs). We say that a subset $Q$ of pure states of a system $K$ can be masked by an operator $S$ into a multipartite system $\H^{(n)}$ if all of the image states $S|\psi\>$ of states $|\psi\>$ in $Q$ have the same marginal states on each subsystem. We call such an $S$ a QMM of $Q$. By establishing an expression of a QMM, we obtain a relationship between QMMs and QECCs, which reads that an isometry is a QMM of all pure states of a system if and only if its range is a QECC of any one-erasure channel. As an application, we prove that there is no an isometric universal masker from $\C^2$ into $\C^2\otimes\C^2\otimes\C^2$ and then the states of $\C^3$ can not be masked isometrically into $\C^2\otimes\C^2\otimes\C^2$. This gives a consummation to a main result and leads to a negative answer to an open question in [PRA 98, 062306 (2018)]. Another application is that arbitrary quantum states of $\C^d$ can be completely hidden in correlations between any two subsystems of the tripartite system $\C^{d+1}\otimes\C^{d+1}\otimes\C^{d+1}$, while arbitrary quantum states cannot be completely hidden in the correlations between subsystems of a bipartite system [PRL 98, 080502 (2007)]., Comment: This is a revision about arXiv:2004.14540. In the present version, $k$ and $j$ old Eq. (2.2) have been exchanged and the followed three equations have been corrected

36. Masking quantum information encoded in pure and mixed states

Abstract

Masking of quantum information means that information is hidden from a subsystem and spread over a composite system. Modi et al. proved in [Phys. Rev. Lett. 120, 230501 (2018)] that this is true for some restricted sets of nonorthogonal quantum states and it is not possible for arbitrary quantum states. In this paper, we discuss the problem of masking quantum information encoded in pure and mixed states, respectively. Based on an established necessary and sufficient condition for a set of pure states to be masked by an operator, we find that there exists a set of four states that can not be masked, which implies that to mask unknown pure states is impossible. We construct a masker $S^\sharp$ and obtain its maximal maskable set, leading to an affirmative answer to a conjecture proposed in Modi's paper mentioned above. We also prove that an orthogonal (resp. linearly independent) subset of pure states can be masked by an isometry (resp. injection). Generalizing the case of pure states, we introduce the maskability of a set of mixed states and prove that a commuting subset of mixed states can be masked by an isometry $S^{\diamond}$ while it is impossible to mask all of mixed states by any operator. We also find the maximal maskable sets of mixed states of the isometries ${S^{\sharp}}$ and ${S^{\diamond}}$, respectively.

Abstract

According to the World Health Organization, the number of mental disorder patients, especially depression patients, has grown rapidly and become a leading contributor to the global burden of disease. However, the present common practice of depression diagnosis is based on interviews and clinical scales carried out by doctors, which is not only labor-consuming but also time-consuming. One important reason is due to the lack of physiological indicators for mental disorders. With the rising of tools such as data mining and artificial intelligence, using physiological data to explore new possible physiological indicators of mental disorder and creating new applications for mental disorder diagnosis has become a new research hot topic. However, good quality physiological data for mental disorder patients are hard to acquire. We present a multi-modal open dataset for mental-disorder analysis. The dataset includes EEG and audio data from clinically depressed patients and matching normal controls. All our patients were carefully diagnosed and selected by professional psychiatrists in hospitals. The EEG dataset includes not only data collected using traditional 128-electrodes mounted elastic cap, but also a novel wearable 3-electrode EEG collector for pervasive applications. The 128-electrodes EEG signals of 53 subjects were recorded as both in resting state and under stimulation; the 3-electrode EEG signals of 55 subjects were recorded in resting state; the audio data of 52 subjects were recorded during interviewing, reading, and picture description. We encourage other researchers in the field to use it for testing their methods of mental-disorder analysis.

Quantum Physics
Abstract

Bell nonlocality and Einstein-Podolsky-Rosen (EPR) steering are every important quantum correlations of a composite quantum system. Bell nonlocality of a bipartite state is a quantum correlation demonstrated by some local quantum measurements, while EPR steering is another form of quantum correlations, observed firstly by Schrodinger in the context of famous EPR paradox. In this paper, we give some remarks on Bell nonlocality and EPR steering of bipartite states, including mathematical definitions and characterizations of these two quantum correlations, the convexity and closedness of the set of all Bell local states and the set of all EPR unsteerable states. We also derive a EPR-steering criteria, with which the EPR steerability of the maximally entangled states are checked.
