Abstract

Objectives
Vitamin D promotes both lipolysis and lipogenesis, and some pediatric studies showed inconsistent associations between vitamin D and metabolic syndrome (MetS). This cross-sectional study aimed to examine the association between vitamin D levels and MetS components among metropolitan adolescents.

Methods
A total of 4,149 adolescents aged 10–18 years were recruited from 23 metropolises in China. The MetS conditions were assessed according to the International Diabetes Federation consensus definition, and the serum 25-hydroxy vitamin D (25(OH)D) concentrations were analyzed. The association between MetS components and serum 25(OH)D levels was analyzed by the logistic regression model. Restricted cubic spline was applied to the model nonlinear association.

Results
Prevalence of vitamin D deficiency was 74.9%, and 41.2% of study participants had at least one MetS component. After adjustment, the significant trend for a lower waist-to-height ratio was not observed in study participants with higher serum 25(OH)D quartile (p=0.57), but a significant nonlinear association between abdominal obesity and serum 25(OH)D levels was found (p=0.04): the highest risk of abdominal obesity occurred at 14.1 ng/mL of serum 25(OH)D. The association of serum 25(OH)D was significantly inverse with MetS (OR: 0.95; 95% CI: 0.92–0.98), but not with raised triglycerides (OR: 0.99; 95% CI: 0.96–1.01), raised blood pressure (OR: 0.99; 95% CI: 0.97–1.01) and impaired fasting glycemia (OR: 1.03; 95% CI: 1.01–1.04).

Conclusions
The net effect of vitamin D on lipid metabolism may be concentration-dependent, and the actual effect of vitamin D on MetS process may be complex among metropolitan adolescents, though serum 25(OH)D is inversely associated with MetS.

Abstract

Objectives
This study aimed to evaluate the relationship between C-reactive protein/albumin (CRP/Alb), neutrophil/lymphocyte (NLR), platelet/lymphocyte (PLR) ratios and the Acute Physiology And Chronic Health Evaluation II (APACHE II) score and 28-day mortality among 400 patients admitted to internal medicine and anesthesia reanimation intensive care unit (ICU).

Methods
This prospective study included a total of 400 patients who were admitted to hospital internal medicine and anesthesia reanimation ICUs.

Results
The most common reasons for ICU admission were pneumonia (29.3%), gastrointestinal bleeding (10.3%), acute exacerbation of chronic kidney disease (CKD) (10.3%), and acute kidney injury (7.5%). The comparison of the laboratory findings with survival outcomes revealed that among the patients with acute exacerbation of CKD, the median NLR (p=0.043) and median CRP/Alb (p=0.021) were significantly higher in patients who died. For all of the patients, the APACHE II score was positively correlated with CRP (p<0.001) and CRP/Alb (p<0.001), negatively correlated with Alb (p<0.001), positively correlated with the NLR (p<0.001), and positively correlated with the PLR.

Conclusions
The APACHE II score was significantly correlated with the CRP/Alb ratio, NLR, and PLR. The NLR and CRP/Alb ratio were statistically associated with mortality in patients hospitalized for acute exacerbation of CKD.

Abstract
Radio frequency identification (RFID) is a widely used wireless technology for contactless data exchange. Owing to international standardization and one-way security nature of the communication protocol, RFID tags, holding sensitive information, may be a subject to theft. One of the major security loopholes is the so-called far-field attack, where unauthorized interrogation is performed from a distance, bypassing the user’s verification. This loophole is a penalty of using a dipole-like RFID tag antenna, leaking wireless information to the far-field. Here we introduce a new concept of anapole-enabled security, prohibiting far-field attacks by utilizing fundamental laws of physics. Our design is based on radiationless electromagnetic states (anapoles), which have high near-field concentration and theoretically nulling far-field scattering. The first property enables performing data readout from several centimeters (near-field), while the second prevents attacks from a distance, regardless an eavesdropper’s radiated power and antenna gain. Our realization is based on a compact 3 cm high-index ceramic core–shell structure, functionalized with a thin metal wire and an integrated circuit to control the tag. Switching scheme was designed to provide a modulation between two radiation-less anapole states, blocking both up and down links for a far-field access. The anapole tag demonstrates more than 20 dB suppression of far-field interrogation distance in respect with a standard commercial tag, while keeping the near-field performance at the same level. The proposed concept might significantly enhance the RFID communication channel in cases, where information security prevails over cost constrains.
Reconfigurable terahertz metasurfaces coherently controlled by wavelength-scale-structured light

Published: November 2021

Abstract
Structuring light–matter interaction at a deeply subwavelength scale is fundamental to optical metamaterials and metasurfaces. Conventionally, the operation of a metasurface is determined by the collective electric polarization response of its lithographically defined structures. The inseparability of electric polarization and current density provides the opportunity to construct metasurfaces from current elements instead of nanostructures. Here, we realize metasurfaces using structured light rather than structured materials. Using coherent control, we transfer structure from light to transient currents in a semiconductor, which act as a source for terahertz radiation. A spatial light modulator is used to control the spatial structure of the currents and the resulting terahertz radiation with a resolution of

Negative optical force field on supercavitating titanium nitride nanoparticles by a single plane wave
Authors: Lee Eungkyu , Luo Tengfei 
Published: November 2021

Abstract
A pulling motion of supercavitating plasmonic nanoparticle (NP) by a single plane wave has received attention for the fundamental physics and potential applications in various fields (e.g., bio-applications, nanofabrication, and nanorobotics). Here, the supercavitating NP depicts a state where a nanobubble encapsulates the NP, which can be formed via the photo-thermal heating process in a liquid. In this letter, we theoretically study the optical force on a supercavitating titanium nitride (TiN) NP by a single plane wave at near-infrared wavelengths to explore optical conditions that can potentially initiate the backward motion of the NP against the wave-propagating direction. An analysis with vector spherical harmonics is used to quantify the optical force on the NP efficiently. Next, the vector field line of the optical force is introduced to visualize the light-driven motion of the NP in a nanobubble. Finally, we characterize the vector field lines at various optical conditions (e.g., various sizes of NP and nanobubble, and wavelength), and we find a suitable window of the optical state which can potentially activate the backward motion of the supercavitating TiN NP.

Abstract
Multi-level (qudit) entangled photon states are a key resource for both fundamental physics and advanced applied science, as they can significantly boost the capabilities of novel technologies such as quantum communications, cryptography, sensing, metrology, and computing. The benefits of using photons for advanced applications draw on their unique properties: photons can propagate over long distances while preserving state coherence, and they possess multiple degrees of freedom (such as time and frequency) that allow scalable access to higher dimensional state encoding, all while maintaining low platform footprint and complexity. In the context of out-of-lab use, photon generation and processing through integrated devices and off-the-shelf components are in high demand. Similarly, multi-level entanglement detection must be experimentally practical, i.e., ideally requiring feasible single-qudit projections and high noise tolerance. Here, we focus on multi-level optical Bell and cluster states as a critical resource for quantum technologies, as well as on universal witness operators for their feasible detection and entanglement characterization. Time- and frequency-entangled states are the main platform considered in this context. We review a promising approach for the scalable, cost-effective generation and processing of these states by using integrated quantum frequency combs and fiber-based devices, respectively. We finally report an experimentally practical entanglement identification and characterization technique based on witness operators that is valid for any complex photon state and provides a good compromise between experimental feasibility and noise robustness. The results reported here can pave the way toward boosting the implementation of quantum technologies in integrated and widely accessible photonic platforms.

Against a uniform analysis of adnominal possessives in Jordanian Arabic: Evidence from nominal ellipsis
Authors: Alhailawani Mohammad 
Published: November 2021

AbstractArabic has two models of adnominal possession: the Construct State and the Free State. Despite their superficial differences, these constructions are traditionally given a uniform analysis, in which their base-generated structures are identical, with differences residing in the movement operations that affect the possessor and the noun. This paper argues against a uniform analysis, based on new evidence from Noun Phrase Ellipsis. Specifically, I argue that the possessor in the Construct State merges in complement position of the possessum, whereas in the Free State, the possessor is an adjunct attached to a higher functional projection above the possessum. An important consequence of this analysis is that a possessor can be introduced in a headcomplement relation.
The protective effects of activating Sirt1/NF-κB pathway for neurological disorders
Authors: Song Yanhong , Wu Ziyi , Zhao Ping 
Published: November 2021

Abstract
Sirt1, a member of the sirtuins family, is a nicotinamide adenosine dinucleotide (NAD+)-dependent deacetylase. It can be involved in the regulation of several processes including inflammatory response, apoptosis, oxidative stress, energy metabolism, and autophagy by exerting deacetylation. Nuclear factor-κB (NF-κB), a crucial nuclear transcription factor with specific DNA binding sequences, exists in almost all cells and plays a vital role in several biological processes involving inflammatory response, immune response, and apoptosis. As the hub of multiple intracellular signaling pathways, the activity of NF-κB is regulated by multiple factors. Sirt1 can both directly deacetylate NF-κB and indirectly through other molecules to inhibit its activity. We would like to emphasize that Sirt1/NF-κB is a signaling pathway that is closely related to neuroinflammation. Many recent studies have demonstrated the neuroprotective effects of Sirt1/NF-κB signaling pathway activation applied to the treatment of neurological related diseases. In this review, we focus on new advances in the neuroprotective effects of the Sirt1/NF-κB pathway. First, we briefly review Sirt1 and NF-κB, two key molecules of cellular metabolism. Next, we discuss the connection between NF-κB and neuroinflammation. In addition, we explore how Sirt1 regulates NF-κB in nerve cells and relevant evidence. Finally, we analyze the therapeutic effects of the Sirt1/NF-κB pathway in several common neuroinflammation-related diseases.
Recht als Gegenstand rhetorischer Grundlagenforschung
Authors: Fischer Jens 
Published: November 2021

Abstract
According to the self-image of lawyers, jurisprudence is a science: the premises in legal conclusions are truth-apt, as are the conclusions or judgements that follow from them, the cognition of true law is consequently regarded as their task. Against this background, a program that understands and analyzes law as the product of a rhetorical practice is confronted with fierce resistance. According to the research of analytical legal rhetoric, on the other hand, the evidence for a rhetorical imprint on law is overwhelming: starting with the logical status of legal inferences, to the peculiarities of judicial procedure, to the motivational situation of those involved in it, everywhere it becomes apparent that the image of strict truth-orientation inadequately describes the genesis of law. Following Aristotle, who assigned law to the field of phrónēsis and not to epistēmē, contemporary legal rhetoric research aims to draw a realistic picture of the genesis of law. Subdivided into the triad of logos, ethos, and pathos, it attempts to fully grasp the interrelationships involved. It becomes apparent that the rational or argumentative dimension is far from dominating in legal justifications. It is precisely at the neuralgic point, i.e., where arguments are opposed to each other, that the rhetor typically uses a rhetorical figure that links all levels of the triad: the restrictio.
A Simple Model of Corporate Fiduciary Duties: With an Application to Corporate Compliance
Authors: Bunting William C. 
Published: November 2021

Abstract
This article models the duty of care as a response to moral hazard where the principal seeks to induce effort that is costly to the agent and unobservable by the principal. The duty of loyalty, by contrast, is modeled as a response to adverse selection where the principal seeks truthful disclosure of private information held by the agent. This model of corporate loyalty differs importantly with standard adverse selection models, however, in that the principal cannot use available contracting variables as a screening mechanism to ensure honest disclosure and must rely upon the use of an external third-party audit technology, such as the court system. This article extends the model to the issue of corporate compliance and argues that the optimal judicial approach would define the duty to monitor as a subset of due care – and not loyalty – but hold that the usual legal protections provided for due care violations no longer apply.
A discourse analysis of Montenegrin university lectures: How structured are they?
Authors: Živković Branka 
Published: November 2021

Summary
In comparison to different genres of written discourse, the structure of university lectures remains insufficiently explored. This paper examines which structural elements the mediostructure of Montenegrin lectures consists of, what functions they serve and what features are typical in their internal organisation. The study further aims to determine which linguistic resources are frequently used in the units identified, as well as to define their functions and examine the relation between the mediostructural units and their linguistic characteristics. Applying a part of Cook's model (1975) and conducting frequency and qualitative analyses, we explore a specially compiled corpus of Montenegrin linguistic lectures. The analysis reveals that the lecture mediostructure includes four structural components performing specific communicative functions. They are characterised by the common use of specific linguistic features influenced by the unit in question. The results could be useful to lecturers to successfully plan and structure their lectures, as well as for future research regarding this institutional genre.

Published: November 2021

A fundamental regulator of neuronal network development and plasticity is the extracellular matrix (ECM) of the brain. The ECM provides a scaffold stabilizing synaptic circuits, while the proteolytic cleavage of its components and cell surface proteins are thought to have permissive roles in the regulation of plasticity. The enzymatic proteolysis is thought to be crucial for homeostasis between stability and reorganizational plasticity and facilitated largely by a family of proteinases named matrix metalloproteinases (MMPs). Here, we investigated whether MMP2 and MMP9 play a role in mediating adult primary visual cortex (V1) plasticity as well as stroke-induced impairments of visual cortex plasticity in mice. In healthy adult mice, selective inhibition of MMP2/9 for 7 d suppressed ocular dominance plasticity. In contrast, brief inhibition of MMP2/9 after a cortical stroke rescued compromised plasticity. Our data indicate that the proteolytic activity of MMP2 and MMP9 is critical and required to be within a narrow range to allow adult visual plasticity.SIGNIFICANCE STATEMENTLearning and recovery from injuries depend on the plasticity of neuronal connections. The brain's extracellular matrix (ECM) provides a scaffold for stabilizing synaptic circuits, while its enzymatic proteolysis is hypothesized to regulate homeostasis between stability and reorganizational plasticity. ECM digestion is facilitated by a family of matrix metalloproteinases (MMPs). Here, we show that treatments that inhibit MMP2/9 can either inhibit or rescue cortical plasticity depending on cortical state: in the visual cortex of healthy adult mice, inhibition of MMP2/9 suppressed cortical plasticity. In contrast, brief inhibition of MMP2/9 after a stroke rescued compromised plasticity. Our data provide strong evidence that an optimal level of MMP2/9 proteolytic activity is crucial for adult visual plasticity.
Economic Choices under Simultaneous or Sequential Offers Rely on the Same Neural Circuit
Authors: Shi Weikang , Ballesta Sébastien , Padoa-Schioppa Camillo 
Published: November 2021

A series of studies in which monkeys chose between two juices offered in variable amounts identified in the orbitofrontal cortex (OFC) different groups of neurons encoding the value of individual options (offer value), the binary choice outcome (chosen juice), and the chosen value. These variables capture both the input and the output of the choice process, suggesting that the cell groups identified in OFC constitute the building blocks of a decision circuit. Several lines of evidence support this hypothesis. However, in previous experiments offers were presented simultaneously, raising the question of whether current notions generalize to when goods are presented or are examined in sequence. Recently, Ballesta and Padoa-Schioppa (2019) examined OFC activity under sequential offers. An analysis of neuronal responses across time windows revealed that a small number of cell groups encoded specific sequences of variables. These sequences appeared analogous to the variables identified under simultaneous offers, but the correspondence remained tentative. Thus, in the present study, we examined the relation between cell groups found under sequential versus simultaneous offers. We recorded from the OFC while monkeys chose between different juices. Trials with simultaneous and sequential offers were randomly interleaved in each session. We classified cells in each choice modality, and we examined the relation between the two classifications. We found a strong correspondence; in other words, the cell groups measured under simultaneous offers and under sequential offers were one and the same. This result indicates that economic choices under simultaneous or sequential offers rely on the same neural circuit.SIGNIFICANCE STATEMENTResearch in the past 20 years has shed light on the neuronal underpinnings of economic choices. A large number of results indicates that decisions between goods are formed in a neural circuit within the orbitofrontal cortex. In most previous studies, subjects chose between two goods offered simultaneously. Yet, in daily situations, goods available for choice are often presented or examined in sequence. Here we recorded neuronal activity in the primate orbitofrontal cortex alternating trials under simultaneous and under sequential offers. Our analyses demonstrate that the same neural circuit supports choices in the two modalities. Hence, current notions on the neuronal mechanisms underlying economic decisions generalize to choices under sequential offers.
