Integrating species and successional classes for wood production in a mixed forest restoration system in a neotropical region

As forests in neotropical regions,particularly in developing countries,are devastated,interventions to restore biodiversity and its ecological functions are needed.Rural producers have thus been encouraged to grow trees for wood production as an economic activity.The objective of this study was to quantify the increment of wood density of four forest species from different successional classes of a mixed system of restoration in a neotropical forest in Brazil.Tree discs were sampled at breast height and analyzed radially by X-ray densitometry to obtain apparent density and basic density.Three trees each of a species from the pioneer,early and late secondary successional stages and of the dominant species in the climax community.The radial profiles indicated increasing density from the pith to bark of trunks,except for some variations due to wood defects and growth.Average density was 0.576 g cm~(-3),0.655 g cm~(-3),0.706 g cm~(-3) and 0.775 g cm~(-3),respectively,for Peltophorum dubium,Schinus terebinthifolius,Cariniana estrellensis and Hymenaea courbaril.Radial profiles indicated higher amplitudes in the apparent densities for slow-growing species.X-ray densitometry generated parameters such as minimum,average and maximum densities,and radial density variations.These parameters are important for understanding the ecological functional role of successional classes of the Atlantic Forest from the Neotropical region.
产前超声诊断单侧上肢完全型海豹肢畸形1例

海豹肢畸形是罕见的体表畸形,发生率是0.62/100 000,其发生与药物、生物、化学、环境等因素有关,属于混合型的纵行肢体缺陷,一般上肢较下肢严重。主要分为完全型、部分型、未分化型3种类型。完全型海豹肢畸形是指胎儿的肱骨、尺骨、桡骨均缺失或股骨、胫骨、腓骨均不存在,胎儿的手或足直接与躯体连接;部分型海豹肢可以是上臂或大腿缺失,前臂及手或小腿及足直接连于躯干,也可以是前臂或小腿缺失,手或足直接连于上臂或者大腿;未分化型海豹肢指胎儿肢体长骨存在,但呈缩短状态且伴有骨骼异常。产前超声是诊断胎儿畸形的重要检查手段,最佳检查时间是孕18~24周,此阶段胎儿解剖结构已经形成,胎儿大小与羊水量适中,有利于超声检查,本例胎儿于孕17周时确诊为海豹肢畸形。产前早期发现胎儿肢体异常,有助于指导临床医生对胎儿做出整体评估,指导孕妇及家属在早期做出最佳选择,缩短孕妇的无效妊娠时间,减少新生儿出生畸形率。对于肢体的检查,超声应该采用连续顺序追踪多切面扫查的方式,先上肢后下肢,双侧肢体均需全面检查。股骨属于常规产科超声检查内容,故下肢畸形一般不会遗漏,而上肢结构不在常规超声检查范围内,容易漏诊。海豹肢畸形胎儿手指或脚趾在数目、结构上可存在异常,严重程度不一。文献报道双侧或四肢完全型海豹肢畸形多见,本例为单侧上肢完全型海豹肢畸形,属于罕见类型。海豹肢畸形可同时合并颜面部畸形、心脏畸形、肾脏畸形等,也可合并某些综合征,如Roberts SC综合征,本例胎儿合并有法洛四联症。海豹肢畸形还需与羊膜带综合征、致死性骨发育不良等相鉴别。在二维超声基础上,三维超声可更全面、立体的显示胎儿外观,以及残余组织与邻近躯体的关系,为确诊体表畸形及其分型提供有利证据,减少胎儿肢体畸形的漏诊及误诊。

Electrical and optical characteristics of highly transparent MOVPE-grown AlGaN-based tunnel heterojunction LEDs emitting at 232 nm

We present the growth and electro-optical characteristics of highly transparent AlGaN-based tunnel heterojunction light-emitting diodes (LEDs) emitting at 232 nm entirely grown by metalorganic vapor phase epitaxy (MOVPE).A GaN:Si interlayer was embedded into a highly Mg-and Si-doped Al0.87Ga0.13N tunnel junction to enable polarization field enhanced tunneling.The LEDs exhibit an on-wafer integrated emission power of 77 μWat 5 mA,which correlates to an external quantum efficiency (EQE) of 0.29% with 45 μWemitted through the bottom sapphire substrate and 32 μW emitted through the transparent top surface.After depositing a highly reflective aluminum reflector,a maximum emission power of 1.73 mW was achieved at 100 mA under pulsed mode operation with a maximum EQE of 0.35% as collected through the bottom substrate.
Covert wireless communication using massive optical comb channels for deep denoising

Covert wireless communications are unprecedentedly vital for security and privacy of individuals,government,and military bodies.Besides encryption,hiding signal transmission deeply under noise background highly proliferates the covertness in the physical layer.A deep signal hiding leads to a low interception probability at the interceptor but a poor data recovery at the receiver.To ensure both high covertness and high-fidelity recovery,massive and dense optical comb channels are utilized for deep denoising through the analog spectrum convolution.Using an external modulation-based optical frequency comb (OFC) and a single detection branch,the available optical comb channels can sustainably scale up by breaking or greatly mitigating physical bottlenecks on immense hardware and spectrum requirements.Thus,a striking signal-to-noise ratio (SNR) rise can be achieved for deep denoising.Combination of 1024 comb channels (the first parallel comb channel number beyond 1000) and the analog spectrum convolution enable a record SNR enhancement of 29 dB for a microwave signal with a 10.24 GHz bandwidth and a 10 Mbit/s data rate,which is deeply hidden below the in-band noises by 18 dB or even 30 dB in both the frequency and time domains.This method opens a new avenue for covert communications.
All-dielectric photonic crystal with unconventional higher-order topology

Photonic crystals (PhCs) have been demonstrated as a versatile platform for the study of topological phenomena.The recent discovery of higher-order topological insulators introduces new aspects of topological PhCs that are yet to be explored.Here,we propose an all-dielectric PhC with an unconventional higher-order band topology.Besides the conventional spectral features of gapped edge states and in-gap corner states,topological band theory predicts that the corner boundary of the higher-order topological insulator hosts a 2/3 fractional charge.We demonstrate that in the PhC such a fractional charge can be verified from the local density-of-states of photons,through the concept of local spectral charge as an analog of the local electric charge due to the band filling anomaly in electronic systems.Furthermore,we show that by introducing a disclination in the proposed PhC,localized states and a 2/3 fractional spectral charge emerge around the disclination core.The emergence of the fractional spectral charges and topological boundary modes here,however,is distinct from the known cases;particularly by the 2/3 fractional spectral charges and the unique topological indices.The predicted effects can be readily observed in the state-of-the-art experiments and may lead to potential applications in integrated and quantum photonics.
Incoherent imaging through highly nonstatic and optically thick turbid media based on neural network

Imaging through nonstatic scattering media is one of the major challenges in optics,and encountered in imaging through dense fog,turbid water,and many other situations.Here,we propose a method to achieve single-shot incoherent imaging through highly nonstatic and optically thick turbid media by using an end-to-end deep neural network.In this study,we use fat emulsion suspensions in a glass tank as a turbid medium and an additional incoherent light to introduce strong interference noise.We calibrate that the optical thickness of the tank of turbid media is as high as 16,and the signal-to-interference ratio is as low as-17 dB.Experimental results show that the proposed learning-based approach can reconstruct the object image with high fidelity in this severe environment.
Augmenting photoluminescence of monolayer MoS_2 using high order modes in a metal dimer-on-film nanocavity

Plasmonic particle-on-film nanocavities, supporting gap modes with ultra-small volume, provide a great solution to boost light-matter interactions at the nanoscale. In this work, we report on the photoluminescence (PL) enhancement of monolayer MoS_2 using high order modes of an Au nanosphere dimer-on-film nanocavity (DoFN). The high order plasmon modes, consisting of two bonding quadrupoles in the dimer and their images in the Au film, are revealed by combining the polarization-resolved scattering spectra with the numerical simulations. Further integrating the monolayer MoS_2 into the DoFN, these high order modes are used to enhance PL intensity through simultaneously boosting the absorption and emission processes, producing a 1350-fold enhancement factor. It opens an avenue to enhance the light-matter interaction with high order plasmon modes and may find applications in future optoelectronics and nanophotonics devices.
Giant enhancements of high-order upconversion luminescence enabled by multiresonant hyperbolic metamaterials

Photonic nanostructures with resonant modes that can generate large electric field (EF) enhancements are applied to enhance light-matter interactions in nanoscale, bringing about great advances in both fundamental and applied science. However, a small hot spot (i.e., the regions with strong EF enhancements) and highly inhomogeneous EF distribution of the resonant modes usually hinder the enhancements of light-matter interactions in a large spatial scale. Additionally, it is a severe challenge to simultaneously generate multiple resonant modes with strong EF enhancements in a broadband spectral range, which greatly limits the capacity of a photonic nanostructure in boosting optical responses including nonlinear conversion, photoluminescence, etc. In order to overcome these challenges, we presented an arrayed hyperbolic metamaterial (AHMM). This AHMM structure is applied to simultaneously enhance the three-photon and four-photon luminescence of upconversion nanoparticles. Excitingly, the enhancement of the three-photon process is 1 order of magnitude larger than previous records, and for the enhancing four-photon process, we achieve an enhancement of 3350 times, greatly beneficial for overcoming the crucial problem of low efficiency in near infrared light upconversion. Our results demonstrated a promising platform for realizing giant enhancements of light-matter interactions, holding potential in constructing various photonics applications such as the nonlinear light sources.

Ginsenoside Rg1 ameliorates bloodebrain barrier disruption and traumatic brain injury via attenuating macrophages derived exosomes miR-21 release

During the traumatic brain injury (TBI), improved expression of circulatory miR-21 serves as a diagnostic feature. Low levels of exosome-miR-21 in the brain can effectively improve neuroinflammation and bloodebrain barrier (BBB) permeability, reduce nerve apoptosis, restore neural function and ameliorate TBI. We evaluated the role of macrophage derived exosomes-miR-21 (M-Exos-miR-21) in disrupting BBB, deteriorating TBI, and Rg1 interventions. IL-1b-induced macrophages (IIM)-Exos-miR- 21 can activate NF-kB signaling pathway and induce the expressions of MMP-1, -3 and -9 and downregulate the levels of tight junction proteins (TJPs) deteriorating the BBB. Rg1 reduced miR-21-5p content in IIM-Exos (RIIM-Exos). The interaction of NMIIAeHSP90 controlled the release of Exos-miR-21, this interaction was restricted by Rg1. Rg1 could inhibit the Exos-miR-21 release in peripheral blood flow to brain, enhancing TIMP3 protein expression, MMPs proteolysis, and restricting TJPs degradation thus protected the BBB integrity. Conclusively, Rg1 can improve the cerebrovascular endothelial injury and hold the therapeutic potential against TBI disease.
A VSC-based Model for Power Flow Assessment of Multi-terminal VSC-HVDC Transmission Systems

This paper puts forward a new practical voltage source converter (VSC) based AC-DC converter model suitable for conducting power flow assessment of multi-terminal VSCbased high-voltage direct current (VSC-MTDC) systems. The model uses an advanced method to handle the operational limits and control modes of VSCs into the power flow formulation. The new model is incorporated into a unified framework encompassing AC and DC power grids and is solved by using the Newton-Raphson method to enable quadratically convergent iterative solutions. The use of complementarity constraints, together with the Fischer-Burmeister function, is proposed to enable the seamless incorporation of operational control modes of VSC and automatic enforcement of any converter's operational limits that become violated during the iterative solution process. Thus, a dedicated process for checking limits is no longer required. Furthermore, all existing relationships between the VSC control laws and their operational limits are considered directly during the solution of the power flow problem. The applicability of the new model is demonstrated with numerical examples using various multi-terminal AC-DC transmission networks, one of which is a utility-sized power system.
Cross-seam Hybrid MTDC System for Integration and Delivery of Large-scale Renewable Energy

To better utilize the diversity of renewable energies in the U.S., this paper proposes a cross-seam hybrid multi-terminal high-voltage direct current (MTDC) system for the integration of different types of renewable energies in the U. S. Based on a developed station-hybrid converter design, the proposed hybrid MTDC system further investigates the connection methods of renewable energies and develops novel flexible power flow control strategies for realizing uninterrupted integration of renewable energies. In addition, the frequency response control of the hybrid MTDC system is proposed by utilizing the coordination between the converters in the hybrid MTDC system. The feasibility of the hybrid MTDC system and the performance of its corresponding control strategies are conducted in the PSCAD/EMTDC simulation. The simulation results indicate that the proposed hybrid MTDC system could realize the uninterrupted integration of renewable energies and flexible power transmission to both coasts of U.S.
A Grid-tied PV Inverter with Sag-severityindependent Low-voltage Ride Through, Reactive Power Support, and Islanding Protection

This paper proposes a grid-tied photovoltaic (PV) inverter capable of low-voltage ride through (LVRT), reactive power support, and islanding protection. Unlike other LVRT inverters, the proposed inverter is independent of sag severity while maintaining the maximum power-point tracking (MPPT) under normal and faulty conditions. The addition of an energy storage buffer stage mitigates the DC-link voltage surge during sags. At the same time, the inverter injects the reactive power during back-to-back sags of variable depths. The control system of the inverter generates the appropriate reference signals for normal, LVRT, and anti-islanding modes while the MPPT continues running. The salient features of the proposed inverter are: ① active power injection under normal grid conditions; ② sag-depth independent LVRT with reactive power support; ③ no DC-link fluctuations; ④ continuous MPPT mode; and ⑤ simultaneous LVRT and anti-islanding support during a grid outage. The inverter demonstrates an uninterrupted operation and seamless transition between various operating modes. Simulations and the experimental prototype have been implemented to validate the efficacy of the proposed PV inverter.
Non-permanent Pole-to-pole Fault Restoration Strategy for Flexible DC Distribution Network

As the structures of multiple branch lines (MBLs) will be widely applied in the future flexible DC distribution network, there is a urgent need for improving system reliability by tackling the frequent non-permanent pole-to-pole (P-P) fault on distribution lines. A novel fault restoration strategy based on local information is proposed to solve this issue. The strategy firstly splits a double-ended power supply network into two single- ended power supply networks through the timing difference characteristics of a hybrid direct current circuit breaker (HDCCB) entering the recloser. Then, a method based on the characteristic of the transient energy of fault current is proposed to screen the faulty branch line in each single-ended power supply network. Also, a four-terminal flexible DC distribution network with MBLs is constructed on PSCAD to demonstrate the efficacy of the proposed strategy. Various factors such as noise, fault location, and DC arc equivalent resistance are considered in the simulation model for testing. Test results prove that the proposed strategy for fault restoration is effective, and features high performance and scalability.
Analysis and Control of Modular Multi-terminal DC Power Flow Controller with Fault Current Limiting Function

In order to overcome the problems of power flow control and fault current limiting in multi-terminal high voltage direct current (MTDC) grids, this paper proposes a modular multi-terminal DC power flow controller (MM-DCPFC) with fault current limiting function. The topology structure, operation principle, and equivalent circuit of MM-DCPFC are introduced, and such a structure has the advantages of modularity and scalability. The power balance mechanism is studied and a hierarchical power balance control strategy is proposed. The results show that MM-DCPFC can achieve internal power exchange, which avoids the use of external power supply. The fault characteristics of MM-DCPFC are analyzed, fault current limiting and self-protection methods are proposed, and the factors affecting the current limiting capability are studied. The simulation models are established in PLECS, and the simulation results verify the effectiveness of MM-DCPFC in power flow control, fault current limiting, and scalability. In addition, a prototype is developed to validate the function and control method of MM-DCPFC.
Low-frequency Oscillation Damping Control for Large-scale Power System with Simplified Virtual Synchronous Machine

This study focuses on a virtual synchronous machine (VSM) based on voltage source converters to mimic the behavior of synchronous machines (SMs) and improve the damping ratio of the power system. The VSM model is simplified according to some assumptions (neglecting the speed variation and the stator transients) to allow for the possibility of dealing with low-frequency oscillation in large-scale systems with many VSMs. Furthermore, a virtual power system stabilizer (VPSS) structure is proposed and tuned using a method based on a linearized power system dynamic model. The linear and nonlinear analyses examine the stability of two modified versions of a 16-machine power system in which, in the first case, partial classical machines are replaced by VSMs, and in the second case, all SMs are replaced by VSMs. The simulation results of the case studies validate the efficiency of the proposed control strategy.
Phasor-domain Dynamic Model of Asymmetric Current Injection Controller for Converter-interfaced Generator

This paper presents a controller model of asymmetric current injection for converter-interfaced generators suitable for root-mean-square (RMS) phasor-domain, fundamentalfrequency, three-phase, and dynamic simulation tools. The effectiveness of the proposed controller is assessed with simulations in test systems with high percentage of converter-interfaced generation. The simulations focus on the operation of protection relays that use negative-sequence quantities in their directional elements. This paper also presents and compares two strategies to limit reactive negative-sequence currents, and active and reactive positive-sequence currents. A tutorial test system and a regional system part of the actual Brazilian Interconnected Power System are used to assess the correctness of the proposed controller in three-phase fundamental-frequency RMS dynamic simulations.
Power Quality Improvement for Grid-connected PV System Based on Distribution Static Compensator with Fuzzy Logic Controller and UVT/ADALINEbased Least Mean Square Controller

This paper presents a novel method of power quality enrichment in a grid-connected photovoltaic (PV) system using a distribution static compensator (DSTATCOM). The paper consists of two-step control processes. In the primary step, a fuzzy logic controller (FLC) is employed in the DC-DC converter to extract the peak power point from the PV panel, where the FLC produces a switching signal for the DC-DC converter. In the secondary step, a unit vector template (UVT)/adaptive linear neuron (ADALINE)-based least mean square (LMS) controller is adopted in the DC-AC converter, i. e., voltage source converter (VSC). The input to this VSC is the boosted DC voltage, which originates from the PV panel as a result of DC-DC conversion. The VSC shunted with the power grid is known as a DSTATCOM, which can maintain the power quality in the distribution system. The UVT controller generates reference source currents from the grid voltages and DC-link voltages. The ADALINE-based LMS controller calculates the online weight according to the previous weights by the sensed load current. The UVT/ADALINE-based LMS controller of a DSTATCOM performs several tasks such as maintaining the sinusoidal source current, achieving a unity power factor, and performing reactive power compensation. The reference current extracted from the UVT/ADALINE-based LMS controller is fed to the hysteresis current controller to obtain the desired switching signal for the VSC. A 100 kW solar PV system integrated into a three-phase four-wire distribution system through a four-leg VSC is designed in MATLAB/Simulink. The performances of the FLC and UVT/ADALINE-based LMS controllers are demonstrated under various irradiances as well as constant temperature and nonlinear loading conditions.
