TransH-RA: A Learning Model of Knowledge Representation by Hyperplane Projection and Relational Attributes

The TransE model plays a key role in dealing with data sparsity and promotes the development of knowledge graphs completion. However, TransE has some difficulties in dealing with one-to-many, many-to-one, many-to-many and transmission relationships. In order to solve this problem, this paper proposes a knowledge representation learning model based on hyperplane projection and relational attributes, namely TransH-RA. First of all, we introduce the idea of hyperplane projection based on the TransE model, this idea is inspired by TransH, which makes different entities have different roles in a specific relationship, thus reducing the constraints of TransE translation rules, and map the head entity h and tail entity t to the plane of special relation r; Secondly, considering that it is not easy to identify different similar entities, the neighborhood information of entities is added to learn the neighborhood of entities around different entities; Then, in order to further strengthen the ability to deal with complex relationships, attribute features of relationships are added and attribute knowledge is embedded; Eventually, during the training of the model, the probability method is chosen to replace the head and tail entities. Link prediction experiments are conducted on the public datasets FB15K and WN18, and the triple classification experiments on the datasets WN11, FB13 and FB15K are carried out to analyze and verify the effectiveness of the proposed method. The evaluation results show that our method achieves state-of-the-art performance on MeanRank, Hits@10 and ACC indicators compared with TransE and TransH.
Risks in the Management of Polytrauma Patients: Clinical Insights

Abstract Polytrauma, a patient’s condition with multiple injuries that involve multiple organs or systems, is the leading cause of mortality in young adults. Trauma-related injuries are a major public health concern due to their associated morbidity, high disability, associated death, and socioeconomic consequences. Management of polytrauma patients has evolved over the last few decades due to the development of trauma systems, improved pre-hospital assessment, transport and in-hospital care supported by complementary investigations. Recognising the mortality patterns in trauma has led to significant changes in the approach to managing these patients. A structured approach with application of advanced trauma life support (ATLS) algorithms and optimisation of care based on clinical and physiological parameters has led to the development of early appropriate care (EAC) guidelines to treat these patients, with subsequent improved outcomes in such patients. The journey of a polytrauma patient through the stages of pre-hospital care, emergency resuscitation, in-hospital stabilization and rehabilitation pathway can be associated with risks at any of these phases. We describe the various risks that can be anticipated during the management of polytrauma patients at different stages and provide clinical insights into early recognition and effective treatment of these to improve clinical outcomes.
Fiber amplifier with integrated optical cooler

We propose a theoretical model for a laser cooled continuous-wave fiber amplifier. The amplification process takes place in the Yb3+-doped core of a fluoride ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) glass fiber, while the cooling process takes place in the cladding, which is doped with thulium. It is shown that for each value of the pump power and amplified signal there is an optimum distribution of the concentration of the Tm3+ along the length of the fiber amplifier, which provides optimum athermal operation. The influence of a small deviation in the input signal power on the temperature of the fiber with a fixed distribution of the Tm3+ ions in the fiber cladding is investigated.
Linearized stability and irreducibility for a functional differential equation

A principle of linearized stability is given for the abstract functional differential equation $\dot u(t) = Bu(t) + Ku_t $, $t \geqq 0$, $u_0 = f$, where B generates a strongly continuous semigroup of bounded linear operators on a Banach space X, and $K:E = C([ - r_0 ,0],X) \to X$ is a nonlinear, continuously Frechet-differentiable operator. The strong positivity property of irreducibility is also investigated for the semigroup associated with solutions of the linearized equation. The theory is applied to the stability analysis of an equation from population dynamics.
Strömgren-Hβ Photometry of the Rich Open Cluster NGC 6705 (M 11)

We present CCD uvbyβ, photometry of 1419 stars located in the central region of the rich Galactic open cluster NGC 6705 (M11). Our study utilizes photometric data obtained with the 0.9 m WIYN telescope at the Kitt Peak National Observatory. Based on more than 330 stars in the spectral range B–A3, we derive average color excess E(b - y) = 0.33( ± 0.033 s.d.; 0.004 s.e.), corresponding to E(B - V) = 0.45, and average distance modulus 11.30( ± 0.4 s.d.; 0.04 s.e.), corresponding to 1820 ± 30 s.e. pc. Using the F-type stars of the cluster main sequence, we estimate [Fe/H] = -0.06( ± 0.59 s.d.; 0.05 s.e.). Based on PARSEC isochrones for Z = 0.0167, the age of the cluster is estimated as 250 Myr. Moderate differential reddening at the amount of A V = 0.86 is detected. No evidence of extended star formation is found for this cluster.
A 0.0058-mm2 Inductor-Less CMOS Active Balun With Gain and Phase Errors Within −0.1 ± 0.2 dB and −0.18 ± 1.17° From DC to 8 GHz

This paper presents a low-imbalance and inductor-less active balun. The large immittance of the parasitics increases gain and phase errors in single-ended-to-differential conversion at high frequencies. Positive feedback is effective in reducing these errors. However, there is a trade-off between the stability of the feedback and the imbalance correction. This paper analyzes this trade-off, and the common-mode rejection ratio (CMRR) was improved by adding a capacitor. Besides, we established the feedback loops for the imbalance correction are also available for bandwidth extension, that is the additional capacitor improves not only the CMRR but also the high-frequency gain. This peaking technique removes inductors that consume large chip areas. The balun was fabricated in a 0.18- $\mu \text{m}$ CMOS process and achieved a small core area of 0.0058 mm2. In addition, a self-bias scheme using a current mirror was devised. It ensures a good bias current balance and reduces errors. The manufacturing variation of the fabricated baluns was statistically evaluated. To obtain the 99.7% limit of the CMRR, we extended the theory of the random CMRR to the complex plane. The measurement results demonstrated small errors within −0.1±0.2 dB and −0.18±1.17° including a variation of $\pm 3\sigma $ from DC to 8.0 GHz.
Study on the stiffness and damping coefficients of water-lubricated rubber bearings with multiple grooves

By considering the effects of multiple grooves, rubber deformation, and actual boundary conditions, the steady elastohydrodynamic lubrication mathematical model and the dynamic Reynolds equation of water-lubricated rubber bearings are presented. The Reynolds equation is solved numerically by the finite difference method, and the stiffness and damping coefficients are calculated from the real and imaginary parts of the integrated pressure. Analysis results suggest that angular velocity, eccentricity ratio, groove configuration, and radial clearance have significant effects on the steady state and dynamic stiffness as well as damping characteristics, which also help in designing proper structure parameters of water-lubricated rubber bearings to obtain better dynamic performance.
The development and validation of the Leisure Internet Usage Scale (LIUS)

ABSTRACT This study aimed to examine the main constructs related to internet usage for the purpose of leisure and develop a valid and reliable scale to analyse participation in internet activities. By reviewing the literature and the based-on semi-structured focus group interviews, the factors for the internet activity participation were determined. The data were collected from two different participant groups, and exploratory factor analysis (n = 283) and confirmatory factor analysis (n = 307) were performed on the data respectively. The results showed that four factors were linked to leisure activity participation: i) information/self-improvement; ii) shopping, iii) multimedia usage, and iv) social interaction. The validity of the scale was calculated through content, convergent, and divergent validity tests. Internal consistency and stability of the scale were determined through Cronbach’s alpha and Pearson correlation coefficients. In conclusion, the findings revealed that Leisure Internet Usage Scale was a valid and reliable instrument.

Based on the answers to the Health-ITUES questionnaire, ICON3DTM resulted to have a positive additional value in presurgical/surgical planning with 43.4% and 39.6% of responders that rated 4 (agree) and 5 (strongly agree), respectively. Regarding the UEQ questionnaire, both mouse and infrared hand-tracking system resulted to be easy to use for 99% of the responders, while the software resulted to be easy to use for 93.4% of the responders. Conclusions: In conclusion, ICON3DTM has been widely appreciated by urologists thanks to its various applications, from preoperative planning to its support for intraoperative decision-making in both robot-assisted and laparoscopic settings.
LiPo battery energy studies for improved flight performance of unmanned aerial systems

Energy storage is one of the most important determinants of how long and far a small electric powered unmanned aerial system (UAS) can fly. For years, most hobby and experimentalists used heavy fuels to power small drone-like systems. Electric motors and battery storage prior to the turn of the century were either too heavy or too inefficient for flight times of any usable duration. However, with the availability of brushless electric motors and lithium-based batteries everything has changed. Systems like the Dragon Eye, Pointer, and Raven are in service performing reconnaissance, intelligence, surveillance, and target acquisition (RISTA) for more than an hour at a time. More recently, multi-rotor vehicles have expanded small UAS capabilities to include activities with hovering and persistent surveillance. Moreover, these systems coupled with the surge of small, low-cost electronics can perform autonomous and semi-autonomous missions not possible just ten years ago. This paper addresses flight time limitation issues by proposing an experimental method with procedures for system identification that may lead to modeling of energy storage in electric UAS’. Consequently, this will allow for energy storage to be used more effectively in planning autonomous missions. To achieve this, a set of baseline experiments were designed to measure the energy consumption of a mid-size UAS multi-rotor. Several different flight maneuvers were considered to include different lateral velocities, climbing, and hovering. Therefore, the goal of this paper is to create baseline flight data for each maneuver to be characterized with a certain rate of energy usage. Experimental results demonstrate the feasibility and robustness of the proposed approach. Future work will include the development of mission planning algorithms that provide realistic estimates of possible mission flight times and distances given specific mission parameters.
A study on L-threonine and L-serine uptake in Escherichia coli K-12

In the current study, we report the identification and characterization of the yifK gene product as a novel amino acid carrier in E. coli K-12 cells. Both phenotypic and biochemical analyses showed that YifK acts as a permease specific to L-threonine and, to a lesser extent, L-serine. An assay of the effect of uncouplers and composition of the reaction medium on the transport activity indicates that YifK utilizes a proton motive force to energize substrate uptake. To identify the remaining threonine carriers, we screened a genomic library prepared from the yifK-mutant strain and found that brnQ acts as a multicopy suppressor of the threonine transport defect caused by yifK disruption. Our results indicate that BrnQ is directly involved in threonine uptake as a low-affinity but high-flux transporter, which forms the main entry point when the threonine concentration in the external environment reaches a toxic level. By abolishing YifK and BrnQ activity, we unmasked and quantified the threonine transport activity of the LIV-I branched chain amino acid transport system and demonstrated that LIV-I contributes significantly to total threonine uptake. However, this contribution is likely smaller than that of YifK. We also observed the serine transport activity of LIV-I, which was much lower compared with that of the dedicated SdaC carrier, indicating that LIV-I plays a minor role in the serine uptake. Overall, these findings allow us to propose a comprehensive model of the threonine/serine uptake subsystem in E. coli cells.
Violet InGaN/GaN/AlGaN-Based Laser Diodes with an Output Power of 420 mW

The InGaN multiquantum-well-structure laser diode (LD) was grown on epitaxially laterally overgrown GaN on sapphire. The LDs with cleaved mirror facets showed an output power as high as 420 mW per facet under room temperature continuous-wave (CW) operation. The fundamental transverse mode was observed up to an output power of 100 mW. The lifetime of the LDs at a constant output power of 30 mW was longer than 160 h under CW operation at an ambient temperature of 50°C. The wavelength drift caused by the temperature change was estimated to be 0.06 nm/K, while that of the red AlInGaP LDs was 0.3 nm/K.
The time-course linkage between hemolysis, redox, and metabolic parameters during red blood cell storage with or without uric acid and ascorbic acid supplementation

Oxidative phenomena are considered to lie at the root of the accelerated senescence observed in red blood cells (RBCs) stored under standard blood bank conditions. It was recently shown that the addition of uric (UA) and/or ascorbic acid (AA) to the preservative medium beneficially impacts the storability features of RBCs related to the handling of pro-oxidant triggers. This study constitutes the next step, aiming to examine the links between hemolysis, redox, and metabolic parameters in control and supplemented RBC units of different storage times. For this purpose, a paired correlation analysis of physiological and metabolism parameters was performed between early, middle, and late storage in each subgroup. Strong and repeated correlations were observed throughout storage in most hemolysis parameters, as well as in reactive oxygen species (ROS) and lipid peroxidation, suggesting that these features constitute donor-signatures, unaffected by the diverse storage solutions. Moreover, during storage, a general “dialogue” was observed between parameters of the same category (e.g., cell fragilities and hemolysis or lipid peroxidation and ROS), highlighting their interdependence. In all groups, extracellular antioxidant capacity, proteasomal activity, and glutathione precursors of preceding time points anticorrelated with oxidative stress lesions of upcoming ones. In the case of supplemented units, factors responsible for glutathione synthesis varied proportionally to the levels of glutathione itself. The current findings support that UA and AA addition reroutes the metabolism to induce glutathione production, and additionally provide mechanistic insight and footing to examine novel storage optimization strategies.
Radical scavenging activity of Chlorophytum borivilianum L. root extract and its protective role in cauda epididymal sperm integrity in Mus musculus after gamma irradiation

Background: Chlorophytum borivilianum L. is a recognized herbal medicine for the management of impotency in South Asian countries. In Ayurveda, it is used for the management of multiple health conditions, including diabetes, infection, and cardiovascular diseases. Parts of the plant have been used as excellent antioxidants and scavengers of free radicals. Since oxidative stress plays an important role in spermatogenesis and fertility in male populations, this study evaluated the role of ethanolic extract of C. borivilianum roots in epididymal sperm maturation against adversities posed by ionizing gamma irradiation. Materials and methods: Antioxidant potential of C. borivilianum root extract (CRE) was evaluated through DPPH (2,2-diphenylpicrylhydrazyl) and NO (nitric oxide) scavenging assays. Four groups of healthy Swiss albino mice were constituted, which were labeled as follows: Group I: sham control, Group II: 7-day pre-treatment with 50 mg/kg CRE, Group III: 6 Gy irradiation without pre-treatment, and Group IV: 7-day pre-treatment with 50 mg/kg CRE and 6 Gy irradiation on day 7. Swiss albino mice were observed for 30 days and later sacrificed to evaluate sperm quality parameters. Results: CRE showed a remarkable antioxidant potential with IC50 values of 46.37 μg/ml and 98.39 μg/ml for DPPH and NO, respectively. A significant decline (p < 0.001) in cauda epididymal sperm count, motility, and viability was observed in Group III animals. Group IV also showed a substantial decline (p < 0.01) in all three parameters compared to Group I; nonetheless, these were significantly higher than Group III. Morphological alterations indicated a coiled and bent tail, with the presence of cytoplasmic droplets in Group III, which declined substantially in Group IV. The ultrastructure of sperm indicated higher curvature of hook in Group III than Group IV, indicating specific interferences in the sperm maturation process. Conclusion: It was concluded that pre-treatment with 50 mg/kg body weight of CRE could protect sperm during epididymal maturation against oxidative stress.
Zeros of Partition Function for the Husimi-Temperley Model

Some time ago, Katsura1l and Saito2l investigated the Lee-Yang aJ zeros of partition function for the Husimi-Temperley model. 4l.SJ The purpose of this Letter is to study this model again, in connection with general theories of second order phase transition developed in previous r:apers6l (we will use the same notations and definitions as in I and II). We examined in I the phase transition of Ising ferromagnet with the aid of the following two conditions imposed on the distribution function g(O, t) of the Lee-Yang zeros (t>O):
Generation of cumulative jets during underwater explosion of copper wires in the ``X-pinch'' configuration

The results of experiments with underwater electrical explosion of 0.1 mm diameter copper wires in X-pinch configuration are presented. A pulsed generator producing a ∼30 kA-amplitude current with a ∼65 ns rise time was used for the explosion of the wires. Shadowgraph and shearing interferometry techniques were applied for optical diagnostics. Evidence of fast-moving copper jets, originating from the location of the intersection of the exploding wires, is reported. Simultaneous measurement of the expansion of the wires, shock waves, and copper jets showed that the dynamics of the jets strongly resemble the classic problem of a collision of two planes, producing two consecutive cumulative jets.
YOLOv5s-L: object detection for service robots

Object detection, as one of the key technologies of service robots, is becoming increasingly important. For this reason, this paper proposes an improved YOLOv5s-L algorithm based on YOLOv5s for service scenarios such as hotels and shopping malls. With the introduction of Ghost series modules, light weight is realized by reducing the number of parameters and calculations of the network. And different compression ratios for Ghostconv modules are compared. To optimize the algorithm, a large-field contextual feature integration module and the coordinate attention mechanism are introduced, which help to enhance the ability to gain information about small objects in the scene and increase the sensitivity to information such as the position and direction of the target. A qualitative analysis was carried out for the Ghostconv modules with different compression ratios, and it was concluded that there is a large amount of redundancy in the deep features of YOLOv5s. The algorithm’s effectiveness was verified using two data sets, PASCAL VOC2007 and PASCAL VOC2012, and experiments indicate that our improved algorithm outperforms other compared methods.
Colloquium : 100 years of mass spectrometry: Perspectives and future trends

Mass spectrometry (MS) is widely regarded as the most sensitive and specific general purpose analytical technique. More than a century has passed for MS since the ground-breaking work of Nobel laureate Sir Joseph John Thomson in 1913. This Colloquium aims to (1) give an historical overview of the major instrumentation achievements that have driven mass spectrometry forward in the past century, including those leading up to the initial work of Thomson, (2) provide the nonspecialist with an introduction to MS, and (3) highlight some key applications of MS and explore the current and future trends. Because of the vastness of the subject area and quality of the manifold research efforts that have been undertaken over the last 100 years, which have contributed to the foundations and subsequent advances in mass spectrometry, it should be understood that not all of the key contributions may have been included in this Colloquium. Mass spectrometry has embraced a multitude of scientific disciplines and to recognize all of the achievements is an impossible task, such has been the diverse impact of this invaluable technique. Scientific progress is usually made via the cumulative effort of a large number of researchers; the achievements reported herein are only a representation of that effort.
New avenues for high-power high-brightness tandem-pumped fiber lasers

The tandem pumping technique has been proven effective in power scaling of fiber lasers, which enabled the most powerful high-brightness fiber lasers to date. However, further performance improvement of tandem-pumped fiber lasers is challenged by the contradiction between nonlinearity suppression and good beam quality maintaining. To address these challenges, researchers from worldwide devoted to expediting the development of high-power tandem-pumped fiber lasers, and a series of new results and new applications emerged in recent years. This paper will highlight the recent advances in the enabling techniques of high-brightness tandem-pumped fiber lasers and the new applications of tandem pumping since the first review paper on this topic in 2017. A brief outlook on the further development of tandem pumping technique is also given.
