Anti-obesity Effects of Ginsenosides in High-Fat Diet-Fed Rats

Objective: To examine the anti-obesity effects of ginsenosides in Korea Red Ginseng (KRG, Panax ginseng) in rats fed with a high-fat diet (HFD). Methods: Twenty-five 4-week-old obesity rats after receiving an HFD for 5 weeks; subsequently, they were additionally treated with ginsenosides Rb1, Rd, Rg1, or Re (10 mg/kg, intraperitoneal injection) for a further 3 weeks ( =5 in each group). The control rats were fed a normal diet. The food consumption, body weight, locomotor activity, serum lipids, adipose tissues, nitric oxide (NO) expression, leptin, neuropeptide Y (NPY), cholecystokinin (CCK) in the brains were measured. Results: In the HFD-fed rats, body weight, body fat mass, serum levels of leptin and NO were signififi cantly higher than in the control rats ( <0.05 or <0.01). However, the treatment of Rd, Re, and Rb1 markedly decreased body fat mass and body weight ( <0.05). The serum level of leptin and NO in ginsenoside-treated rats were markedly lower than the control group ( <0.01). The expression of NPY and CCK in the hypothalamic nuclei showed insignififi cant difference among groups. However, the expression of NPY immunoreactive neurons in the hypothalamus was signififi cantly reduced in the Rb1-treated group ( <0.05). Conclusion: PD-type ginsenoside Rb1 from the crude saponins of KRG may be a useful compound for the treatment of obesity and related disorders through the modulation of peripheral and central appetite-regulating signals.
Performance characterization of two-way multi-hop underwater networks in turbulent channels [Invited]

This Letter investigates the performance of the two-way multi-hop system for underwater optical wireless communications. With the decode-and-forward (DF) relaying, the two-way multi-hop system is modeled, where the effects of absorption, scattering, and oceanic turbulence are all taken into account. An exact closed-form expression for outage probability is derived under the assumption that the oceanic turbulence obeys a log-normal distribution. Numerical results demonstrate the impacts of various parameters on the outage performance and indicate that the two-way multi-hop system significantly improves the performance in comparison to both the one-way multi-hop system and the two-way two-hop system.
High-speed underwater wireless optical communications: from a perspective of advanced modulation formats [Invited]

In this paper, recent advances in underwater wireless optical communication (UWOC) are reviewed for both LED- and LD-based systems, mainly from a perspective of advanced modulation formats. Volterra series-based nonlinear equalizers, which can effectively counteract the nonlinear impairments induced by the UWOC system components, are discussed and experimentally demonstrated. Both the effectiveness and robustness of the proposed Volterra nonlinear equalizer in UWOC systems under different water turbidities are validated. To further approach the Shannon capacity limit of the UWOC system, the probabilistic constellation shaping technique is introduced, which can overcome the inherent gap between a conventional regular quadrature amplitude modulation (QAM) format and the Shannon capacity of the channel. The experimental results have shown a significant system capacity improvement compared to the cases using a regular QAM.
An Integrated MCI Detection Framework Based on Spectral-temporal Analysis

Aiming to differentiate between mild cognitive impairment (MCI) patients and elderly control subjects,this study proposes an integrated framework based on spectral-temporal analysis for the automatic analysis of resting-state electroencephalogram (EEG) recordings.This framework firstly eliminates noise by employing stationary wavelet transformation (SWT).Then,a set of features is extracted through spectral-temporal analysis.Next,a new wrapper algorithm,named three-dimensional (3-D) evaluation algorithm,is proposed to derive an optimal feature subset.Finally,the support vector machine (SVM) algorithm is adopted to identify MCI patients on the optimal feature subset.Decision tree and K-nearest neighbors (KNN) algorithms are also used to test the effectiveness of the selected feature subset.Twenty-two subjects are involved in experiments,of which eleven persons were in an MCI condition and the rest were elderly control subjects.Extensive experiments show that our method is able to classify MCI patients and elderly control subjects automatically and effectively,with the accuracy of 96.94% achieved by the SVM classifier.Decision tree and KNN algorithms also achieved superior results based on the optimal feature subset extracted by the proposed framework.This study is conducive to timely diagnosis and intervention for MCI patients,and therefore to delaying cognitive decline and dementia onset.
Optimal Design of Co/In/Cu Sputtering Target Assembly Using Finite Element Method and Taguchi Method

Target assembly is a key consumable material for producing thin film used in the electronic packaging and devices.The residual stresses induced during the process of soldering are detrimental to the performance of target assembly.In this work,the intensity and distribution of the soldering residual stress of Co/In/Cu target assembly subjected to a 20 W/(m~2 K) cooling condition corresponding to the actual air cooling process were studied,based on finite element simulation and Taguchi method,to optimize the sputtering target assembly.Eff ects of diff erent control factors,including solder material,thickness of solder layer,target and backing plate,on the soldering residual stress of target assembly are investigated.The maximum residual stress is calculated as 9.28 MPa in the target located at 0.16 mm from target–solder layer interface and at a distance of 0.78 mm from symmetry axis.The optimal design in target assembly has the combination of indium solder material,cobalt target at 12 mm thick,solder layer at 0.8 mm thick,copper backing plate at 15 mm thick.Moreover,solder material is the most important factor among control factors in the target assembly.

Modeling Temporal Dynamics of Users’ Purchase Behaviors for Next Basket Prediction

Next basket prediction attempts to provide sequential recommendations to users based on a sequence of the user’s previous purchases. Ideally, a good prediction model should be able to explore the personalized preference of the users, as well as the sequential relations of the items. This goal of modeling becomes even more challenging when both factors are time-dependent. However, existing methods either take these two aspects as static, or only consider temporal dynamics for one of the two aspects. In this work, we propose the dynamic representation learning approach for time-dependent next basket recommendation, which jointly models the dynamic nature of user preferences and item relations. To do so, we explicitly model the transaction timestamps, as well as the dynamic representations of both users and items, so as to capture the personalized user preference on each individual item dynamically. Experiments on three real-world retail datasets show that our method significantly outperforms several state-of-the-art methods for next basket recommendation.
Survival benefit of pancreatic metastasectomy of clear cell renal cell carcinoma

The clear cell renal cell carcinoma(ccRCC) appears to have a predilection for metastasizing to the pancreas.[1] In the recent years, there are increasing numbers of clinical series from Europe and the United States that demonstrate encouraging survival results of pancreatic metastasectomy,[ 2] but there are a few clinical data or only some case reports from East Asian population,[3] and there are no specific guidelines regarding the appropriate management. The objective of this study was to present our experience of pancreatic metastasectomy from ccRCC by reporting the peri-operative and survival outcome.
Treatment of mallet fractures with a transverse two-hole mini plate

To the Editor: Mallet fracture is a very common hand injury. Although non-surgical treatment for some small fragment cases without distal interphalangeal joint(DIPJ) subluxation is acceptable, many authors have considered restoring the joint surface with accurate reduction to be important to prevent secondary osteoarthritis, loss of movement, and poor cosmetic outcomes.[1] To obtain an accurate reduction, several reduction and fixation techniques(such as extension block pinning, hook plate fixation, umbrella handle like K-wire fixation, and so on) have been developed.[2-4] But when the fracture fragment is small or comminuted, stable fixation is quite difficult to achieve based on the current techniques. To develop a more universal method to deal with different types of mallet fractures with fewer complications, a transverse two-hole mini plate was used.
Synthesis,Crystal Structure and Herbicide Activity of Three Phenyl-naphthyl Methanone Derivatives

Three phenyl-naphthyl methanone derivatives have been designed and synthesized through alkylation and Friedel-Crafts acylation reactions.All the compounds were characterized by IR,~1H NMR,~(13)C NMR and H RMS.The single crystal structure of the compounds has been further determined by X-ray diffraction.(4-Ethoxynaphthalen-1 -yl)(2-methylphenyl)methanone (3a) crystallizes in monoclinic system,P2_1/c space group with a = 13.144(3),b = 11.041(2),c = 11.320(2) A,β= 106.65(3)°,V = 1573.7(5) A~3,D_c = 1.225 Mg/m~3,Z=4,F(000) = 616,µ(MoKa) = 0.078 mm~(-1),R = 0.0928 and wR= 0.1556.(4-Ethoxynaphthalen-1-yl)(2-hydroxyphenyl)methanone (3b) belongs to the monoclinic system,P2_1/c space group with a = 9.985(2),b = 10.814(2),c = 14.353(3) A,β = 105.49(3)°,V = 1493.6(5) A~3,D_c= 1.300 Mg/m~3,Z = 4,F(000) = 616,µ(MoKa) = 0.087 mm~(-1),R = 0.0568 and wR = 0.1262.(4-Methoxynaphthalen-1 -yl)(4-methylphenyl)methanone (3c) crystallizes in monoclinic system,P2_1/c space group with a = 7.6130(15),b = 15.068(3),c = 12.880(3)A,β= 100.63(3)°,V= 1452.1(5)A~3,D_c= 1.264 Mg/m~3,Z = 4,F(000) = 584,µ(MoKα)= 0.081 mm~(-1),R = 0.0804 and wR= 0.1349.The presence of van der Waals forces leads to the stability of the compounds.Especially,compounds 3a ~c showed herbicidal activity against the monocotyledon plant barnyard grass (Echinochloa crus-galli).At the concentration of 0.75 mmol/m~2,compound 3b (C_t = 0.436 ± 0.116 mg/g) exhibited better activity than pyrazoxyfen (C_t = 0.537 ± 0.073 mg/g).
Geotechnical properties and stability of the submarine canyon in the northern South China Sea

The upper part of the continental slope in the northern South China Sea is prone to submarine landslide disasters,especially in submarine canyons.This work studies borehole sediments,discusses geotechnical properties of sediments,and evaluates sediment stability in the study area.The results show that sediment shear strength increases with increasing depth,with good linear correlation.Variations in shear strength of sediments with burial depth have a significantly greater rate of change in the canyon head and middle part than those in the canyon bottom.For sediments at the same burial depth,shear strength gradually increased and then decreased from the head to the bottom of the canyon,and has no obvious correlation with the slope angle of the sampling site.Under static conditions,the critical equilibrium slope angle of the sediments in the middle part of the canyon is 10° to 12°,and the critical slope angle in the head and the bottom of the canyon is 7°.The results indicate that potential landslide hazard areas are mainly distributed in distinct spots or narrow strips on the canyon walls where there are high slope angles.
A numerical study of generation and propagation of type-a and type-b internal solitary waves in the northern South China Sea

Numerical simulations based on a high-resolution three-dimensional MIT general circulation model (MITgcm) using realistic topography and tidal forcing are conducted to investigate the generation and propagation of the socalled type-a waves (large-amplitude rank-ordered wave packets) and type-b waves (isolated wave packets) in the northern South China Sea.At first,we summarized and analyzed the generation and propagation characteristics of these waves.Then,energy budget at the Luzon Strait is calculated.Energy generation has three local maxima every day,of which the largest one corresponds to the emergence of the type-a wave.Energy flux at the west boundary of the Luzon Strait shows two local maxima each day.The larger one is consistent with the generation of the type-a wave and the smaller one is in correspondence with the generation of the type-b wave.Sensitivity experiments are designed to explore the role of the east and west ridge of the Luzon Strait on the generation and propagation of the type-a and type-b waves.It is found that the east ridge is indispensable on the generation of the type-a wave while the west ridge has little contribution.The west ridge diminishes the type-a waves' amplitude but hardly changes their propagation speed.The type-b waves also come from perturbation signals which originate from the east ridge and are enhanced in amplitude and reduced in propagation speed by the west ridge.
Single-photon avalanche diode imagers in biophotonics:review and outlook

Single-photon avalanche diode (SPAD) arrays are solid-state detectors that offer imaging capabilities at the level of individual photons,with unparalleled photon counting and time-resolved performance.This fascinating technology has progressed at a very fast pace in the past 15 years,since its inception in standard CMOS technology in 2003.A host of architectures have been investigated,ranging from simpler implementations,based solely on off-chip data processing,to progressively “smarter” sensors including on-chip,or even pixel level,time-stamping and processing capabilities.As the technology has matured,a range of biophotonics applications have been explored,including (endoscopic) FLIM,(multibeam multiphoton) FLIM-FRET,SPIM-FCS,super-resolution microscopy,time-resolved Raman spectroscopy,NIROT and PET.We will review some representative sensors and their corresponding applications,including the most relevant challenges faced by chip designers and end-users.Finally,we will provide an outlook on the future of this fascinating technology.
Bezier surfaces with special coordinate curve nets

Bezier surfaces play an important role in Computer-aided Geometric Design(CAGD), and coordinate curve nets are widely discussed in differential geometry.In this paper, we study the Bezier surfaces with special coordinate curve nets, such as orthogonal coordinate net, curvature coordinate net and asymptotic coordinate net.In addition, we develop the Bezier surfaces which satisfy some shape constraints with the help of energy terms.Moreover, some applicable sufficient conditions based on geometrical structure of control nets are deduced and several representative examples are given.
Edge partition of graphs embeddable in the Projective plane and the Klein bottle

In a previous paper by the author joint with Baogang XU published in Discrete Math in 2018,we show that every non-planar toroidal graph can be edge partitioned into a planar graph and an outerplanar graph.This edge partition then implies some results in thickness and outerthickness of toroidal graphs.In particular, if each planar graph has outerthickness at most 2(conjectured by Chartrand, Geller and Hedetniemi in 1971 and the confirmation of the conjecture was announced by Goncalves in 2005), then the outerthickness of toroidal graphs is at most 3 which is the best possible due to $K_7$.In this paper we continue to study the edge partition for projective planar graphs and Klein bottle embeddable graphs.We show that(1)every non-planar but projective planar graph can be edge partitioned into a planar graph and a union of caterpillar trees;and(2)every non-planar Klein bottle embeddable graph can be edge partitioned into a planar graph and a subgraph of two vertex amalgamation of a caterpillar tree with a cycle with pendant edges.As consequences, the thinkness of projective planar graphs and Klein bottle embeddabe graphs are at most 2, which are the best possible,and the outerthickness of these graphs are at most 3.
Seed germination and seedling growth of Pycnanthus angolensis (Welw.)Warb., African false nutmeg

This study investigated the germination behavior and seedling growth of Pycnanthus angolensis seeds. The germination study was carried out in the laboratory and included pretreatment studies and observation of the seed-germination process. For each treatment, three replications of 20 seeds were sown in a transparent plastic germination box(12cm×22cm×5cm) lined with moistened filter paper at room temperature. To monitor seedling growth, seedlings were transplanted into pots filled with topsoil and laid out in a completely randomized design. Ten seedlings replicated thrice were measured monthly; and the shoot height, leaf area, and root length, as well as the fresh and dry weights of the seedlings, were recorded. Results showed that mechanically scarified seeds exhibited the significantly highest germination percent(83.33%, P <0.005), followed by control seeds(70.83%), whereas seeds treated with 98% sulphuric acid(H2SO_4) displayed the lowest germination percent(1.67). The endospermous seeds exhibited cryptogeal germination, while seeds stored for a month(with or without arils) failed to germinate. During seed germination, radicle protrusion continued with a pseudo-opening of the root, through which the brownish cotyledonary petiole was emitted, thus releasing the plumule at the posterior position. Moreover, P. angolensis exhibited a slow growth rate, attaining a shoot height of 73 cm within a year. The highest positive change in leaf number and area was recorded in the fourth month, a period during which the least change in shoot height occurred. The study concluded that mechanical scarification of the seeds ensured significant and faster germination than chemical scarification or no treatment at all. Additionally, P. angolensis displayed a cryptogeal germination, with the seedling growth of the tree species observed to be slow.
Hard X-ray Imager (HXI) onboard the ASO-S mission

Hard X-ray Imager(HXI)is one of the three scientific instruments onboard the Advanced Spacebased Solar Observatory(ASO-S)mission, which is proposed for the 25th solar maximum by the Chinese solar community.HXI is designed to investigate the non-thermal high-energy electrons accelerated in solar flares by providing images of solar flaring regions in the energy range from 30 keV to 200 keV.The imaging principle of HXI is based on spatially modulated Fourier synthesis and utilizes about 91 sets of bi-grid sub-collimators and corresponding LaBr3 detectors to obtain Fourier components with a spatial resolution of about 3 arcsec and a time resolution better than 0.5 s.An engineering prototype has been developed and tested to verify the feasibility of design.In this paper, we present background, instrument design and the development and test status of the prototype.
Glacier change in the Tanggula Mountains,Tibetan Plateau,in 1969-2015

To improve our knowledge of glacier change in the Tanggula Mountains located in the northeast of the Tibetan Plateau,we delineated outlines of the glaciers in 1991 and 2015 using Landsat TM/OLI images and compared them with the reported glacier data in the First Chinese Glacier Inventory in 1969 and the Second Chinese Glacier Inventory in 2007.These comparisons showed that the glacier area and ice volume decreased by 524.8 km~2 and 37 km~3,respectively.The majority of the glacier area loss was concentrated in the area class of 1-5 km~2,between 5300 m and 5500 m in elevation,on north and east facing slopes and in the Dam Qu River basin.These glacier changes exhibited spatial and temporal differences.The glacier retreat rate gradually increased from 1969 to 2015,and the rate in the east was higher than that in the west.From 1969 to 2015,the warming rate in the Tanggula Mountains was 0.38°C/10a,while the annual precipitation only increased by 0.4%.The slight increase in the amount of precipitation made a limited contribution to glacier change,while the change in temperature led to noticeable shrinkage of the glaciers.Contrary to the retreat or stagnation of most glaciers in the study area,there were 10 glaciers that experienced clear advance in 1986-2015 with noticeable increases in both area and length.Whether or not these 10 glaciers are surge glaciers requires further study.
Hydro-mechanical response with respect to the air ventilation for water filtration in homogeneous soil

When water penetrates into soil,interstitial air can become trapped by the infiltrating water.Neglecting the effect of air ventilation could cause deviations in the predicted pore water pressure and the associated effective stress.This study aims at the effect of air ventilation on the coupled hydromechanical responses in homogeneous soil during infiltration.A schematic concept of infiltration conditions (open-and closed-valve) in homogeneous soil is proposed for investigating their impacts on the pore water pressure and effective stress.Experiments of vertical soil column filled with Ottawa sand (ASTM C778 20/30) were designed for two types of air ventilation (namely,open and closed infiltration).The evolution of pore water pressure at the cylinder bottom was recorded,and served as a benchmark problem for evaluating the coupled hydro-mechanical response.Coding with the commercial software,GeoStudio,was employed for the dynamic behaviors of pore-water and-air pressures as well as the evolving effective stress.It was found in both the experiments and numerical investigations that the infiltration condition plays a crucial role for the ascending rate of pore water pressure as well as the associated effective stress.These results illustrate the inevitable impacts of the air ventilation conditions on the mechanical properties of the soil during infiltration.
