Comparison of Cardiovascular Outcomes Between Dapagliflozin and Empagliflozin in Patients With Type 2 Diabetes: A Meta-Analysis

Sodium-glucose cotransporter-2 (SGLT2) inhibitors are oral diabetes medications that enhance the excretion of glucose by preventing the renal proximal tubules from reabsorbing glucose, which lowers glucose levels in plasma. Currently, studies have shown that SGLT2 inhibitors have beneficial impacts on cardiovascular outcomes, but their effect varies between the individual SGLT2 inhibitors. Thus, the current meta-analysis was conducted to compare the efficacy of dapagliflozin and empagliflozin in preventing cardiovascular events in patients with type 2 diabetes. The current meta-analysis was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. A search of studies comparing cardiovascular events between dapagliflozin and empagliflozin in patients with type 2 diabetes published up to 1 July 2022 was done by two reviewers independently on PubMed, Embase and Cumulated Index to Nursing and Allied Health Literature (CINAHIL). The pre-specified primary endpoints were cardiovascular death, stroke, myocardial infarction and heart failure. Overall four studies were included in this meta-analysis. No significant difference was found in the incidence of myocardial infarction (risk ratio (RR)=0.81, 95% confidence interval (CI): 0.60-1.09), heart failure (RR=0.76, 95% CI: 0.56-1.04), cardiovascular mortality (RR=0.46, 95% CI: 0.18-1.20) and stroke (RR=1.07, 95% CI: 0.84-1.38) between dapagliflozin and empagliflozin. Results have shown that the risk of developing stroke, heart failure, myocardial infarction and cardiovascular death were not significantly different in the two groups.
Accelerating Tensor Swapping in GPUs With Self-Tuning Compression

Data swapping between CPUs and GPUs is widely used to address the GPU memory shortage issue when training deep neural networks (DNNs) requiring a larger amount of memory than that a GPU may have. Data swapping may become a bottleneck when its latency is longer than the latency of DNN computations. Tensor compression in GPUs can reduce the data swapping time. However, existing works on compressing tensors in the virtual memory of GPUs have three major issues: lack of portability because its implementation requires additional (de)compression units in memory controllers, sub-optimal compression performance for varying tensor compression ratios and sizes, and poor adaptation to dense tensors because they only focus on sparse tensors. We propose a self-tuning tensor compression framework, named CSwap+, for improving the virtual memory management of GPUs. It uses GPUs for (de)compression directly and thus has high portability and is minimally dependent on GPU architecture features. Furthermore, it only applies compression on tensors that are deemed to be cost-effective considering their compression ratio, size, and the characteristics of compression algorithms at runtime. Finally, to adapt to DNN models with dense tensors, it also supports cost-effective lossy compression for dense tensors with nearly no model training accuracy degradation. We conduct the experiments through six representative memory-intensive DNN models. Compared to vDNN, CSwap+ reduces tensor swapping latency by up to 50.9% and 46.1% with NVIDIA V100 GPU, for DNN models with sparse and dense tensors, respectively.
Electric field induced phase transition in charge-ordered LuFe2O4

The measurements of resistance under various applied voltages as well as the highly nonlinear current-voltage characteristics reveal that a small electric field is able to induce an insulating to metallic phase transition in LuFe2O4. The threshold field at which the phase transition occurs decreases exponentially with the increasing temperature. We interpret this transition as a consequence of the breakdown of the charge-ordered state triggered by applied electric field. This electrically driven phase transition results in a colossal electroresistance effect around room temperature which makes LuFe2O4 a very promising material for many applications.
Biosorbtion, localization and bioavailability of zinc in Spirulina platensis culture

A study of Spirulina platensis taking up Zn was conducted in modified culture media with various Zn salts. Spirulina platensis cultured for 7 days in modified Zarrouk’s medium 1.6 µmol Zn of ZnSO4 (MZS) contained the highest Zn content. The MZS were 69.55±2.70 µg/g dry weight for Zn concentration, 63.11±1.40 %db for protein content, 0.46 day-1 for specific growth rate (µ), 0.55 g/L.day dry weight cell for productivity (Px), and 1.50 days for doubling time (td). The majority of Zn deposit was in the cytoplasm which was 2.7- fold higher than that in the cell walls. Fourier transform infrared (FTIR) spectra showed the decreasing of peak intensity for the amide groups after Zn uptake which indicated their important role in the binding of Zn. The simulated digestion in gastric and intestinal tracks of S. platensis cells cultured in MZS cells was the accessibility of 55.20±0.57 and 63.55±0.21%, respectively. After sequentially gastric and intestinal digestion, the Zn availability was 34.63±0.95%.
Energy Efficient Train-Ground mmWave Mobile Relay System for High Speed Railways

The rapid development of high-speed railways (HSRs) puts forward high requirements on the corresponding communication system. Millimeter wave (mmWave) can be a promising solution due to its wide bandwidth, narrow beams, and rich spectrum resources. However, with the large number of antenna elements employed, energy-efficient solutions at mmWave frequencies are in great demand. Based on a mmWave HSR communication system with multiple mobile relays (MRs) on top of the train, a dynamic power-control scheme for train-ground communications is proposed. The scheme follows the regular movement characteristics of high-speed trains and considers three phases of train movement: the train enters the cell, all MRs are covered in the cell, and the train leaves the cell. The transmit power is further refined according to the number of MRs in the cell and the distance between the train and the remote radio head. By minimizing energy consumption under the constraints of the transmitted data and transmit power budget, the transmit power is allocated to multiple MRs through the multiplier punitive function-based algorithm. Comprehensive simulation results, where the velocity estimation error is taken into account, are provided to demonstrate the effectiveness of the proposed scheme over several baseline schemes.
Factors influencing the success of hand-reared juvenile brushtail possums (Trichosurus vulpecula) released into the wild

Abstract Context. Wildlife is ubiquitous in urban environments, resulting in frequent interactions with humans and human infrastructure. The result of these interactions is often negative, in the form of road injury, orphaning of dependent young or eviction from natural home ranges. Wildlife rehabilitation programmes are devised to counter these negative interactions. However, the success of current management strategies is rarely assessed. Aims. We aimed to determine whether short-term survival of juvenile hand-reared common brushtail possums (Trichosurus vulpecula) released in the wild was a function of (1) intrinsic factors such as sex, individual personality and level of human habituation, and (2) extrinsic factors such as release practice (soft vs hard-release) or location (urban vs rural). We also evaluated the relationship between habituation to humans and time spent in care by possums, if presence of conspecifics during the rehabilitation process influenced the development of individual personality, and if this differed in hand-raised animals compared with wild individuals. Methods. We radio-tracked and monitored 20 hand-reared juvenile possums (10 females and 10 males) for up to 40 days after release in the wild. Key results. Eight possums (40%) survived until the end of the study, nine possums (45%) were killed by foxes or had to be returned into care and three possums (15%) had unknown fates (i.e. lost VHF signal). We found that more exploratory individuals and those less human-habituated were more likely to be successful in the wild in both rural and urban areas, whether or not they were hard or soft released. Conclusions. Our results suggest that personality is a key criterion to consider when evaluating the success of rehabilitation programmes. Behavioural traits of hand-reared brushtail possums differed significantly from those of wild individuals, showing that captive conditions can affect the development of personality. Hand-reared possums that spent more time in care were also more likely to display highly human-habituated behaviours. Implications. By demonstrating which factors influence success of hand-reared wildlife after release in the wild, our results help in evaluating current rearing and release practices, and improve the evidence base for developing best practice wildlife rehabilitation guidelines.
Ultrahigh room-temperature hole Hall and effective mobility in Si0.3Ge0.7/Ge/Si0.3Ge0.7 heterostructures

We have obtained ultrahigh room-temperature (RT) hole Hall and effective mobility in Si0.3Ge0. 7/Ge/Si0.3Ge0. 7 heterostructures with very small parallel conduction. Reducing parallel conduction was achieved by employing Sb doping in Si0.3Ge0. 7 buffer layers, which drastically increased RT hole Hall mobility up to 2100 cm2/V s in the strained Ge channel modulation-doped structures and improved device characteristics of the p-type metal–oxide–semiconductor field-effect transistors with the strained Ge channel. The peak effective mobility reached to 2700 cm2/V s at RT, which was much higher than the bulk Ge drift mobility.
A Bionics-Based Recovery Strategy for Micro Air Vehicles

Micro air vehicles' (MAVs) movements can be significantly affected by physical contact with unknown moving objects (UMOs) from a random direction. To address this problem, low-latency sensors (cameras or radars) and high-speed processors are installed in six directions of aerial vehicles. However, this method is limited by hardware costs, load, and energy. In this article, a fast recovery strategy for MAVs is proposed, which is inspired by the recovery manoeuvre of mosquitoes hit by raindrops. When hit by falling raindrops, mosquitoes will descend along the falling direction of raindrops to gradually counteract the kinetic energy of the impact induced by the raindrops. During the descent, mosquitoes will gradually tilt to one side but move in the opposite direction, and finally deviate from the falling route of raindrops. To simulate the recovery strategy, a micro aerial robot called RobMos is designed. The RobMos is an overactuated system that can decouple the position control from the attitude control. Using the recovery strategy, the robot can quickly recover to a stable attitude after being impacted by UMOs. An onboard inertial measurement unit is used to estimate the impact location. Finally, the prototype can bear the impact of objects that are two times its own weight. Moreover, the generalizability of this strategy is also discussed, and it is proved that the RobMos can even recover attitude after being hit by the UMO in a lateral direction.
Land Procurement for Public Interest Against Destroyed Land: Natural Events and Legal Certaint

Based on a case study on the construction of the Semarang-Demak Toll Road, this study aims to investigate and investigate land acquisition for the public interest for land that has been destroyed as a result of natural events and its legal certainty. The research method used is socio-legal with primary data in identification, field measurements, and other supporting data. Semarang-Demak Toll Road property acquisition demonstrated tidal inundation on the north shore. Subsidence exacerbates Semarang's flooding. On flooded land, sea dikes and retention ponds prevent tidal floods. If just for transportation, the Semarang-Demak Toll Road can be built in flood-free areas or over the sea, like Bali's Mandra Toll Road. Land acquisition concerns delayed the Semarang-Demak Toll Road. Lack of land limitations has delayed land purchases. In the Semarang-Demak Toll Road land acquisition, destroyed land is not a problem under Indonesian law. 2021's Regulation 18 defines destroyed land. Destroyed land will drive people to take better care of their land and be more concerned about global warming or land subsidence. The state honors the landowner's emotional connection by paying for spiritual care. Doi: 10.28991/CEJ-2022-08-06-06 Full Text: PDF
Necessary and sufficient optimality conditions for some robust variational problems

In this article, we complete the study started in Treanţă 15$$ {}^{15} $$ on multidimensional scalar variational control problems with mixed constraints implying partial differential equations and inequations of second‐order. More specifically, under convexity assumptions of the involved uncertain functionals of multiple integral type, we state necessary and sufficient optimality conditions for a class of robust variational problems with uncertainty in the constraint and objective functionals.
Secure User Verification and Continuous Authentication via Earphone IMU

Biometric plays an important role in user authentication. However, the most widely used biometrics, such as facial feature and fingerprint, are easy to capture or record, and thus vulnerable to spoofing attacks. On the contrary, intracorporal biometrics, such as electrocardiography and electroencephalography, are hard to collect, and hence more secure for authentication. Unfortunately, adopting them is not user-friendly due to their complicated collection methods or inconvenient constraints on users. In this paper, we propose a novel biometric-based authentication system, namely MandiPass. MandiPass leverages inertial measurement units, which have been widely deployed in portable devices, to collect intracorporal biometric from the vibration of user's mandible. It provides not only one-time verification function but also continuous authentication function. Both the two functions are secure and user-friendly. We theoretically validate the feasibility of MandiPass and develop a series of deep learning techniques for effective biometric extraction. We also utilize a Gaussian matrix to defend against replay attacks. Extensive experiment results with 34 volunteers show that MandiPass can achieve low equal error rate, even under various harsh environments.
TRACKING THE GODZILLA DUST PLUME USING GOOGLE EARTH ENGINE PLATFORM

Abstract. As part of Earth’s nutrient cycle, a layer of air travels every summer from Africa across the Atlantic Ocean. In June 2020, the thickest and densest dust plume traveled over 5000 miles along with the Saharan Air Layer (SAL) from Africa towards the USA and the Caribbean. Due to its gravity and impact, it was nicknamed “Godzilla”. While the cause of this event remains unclear, the advantage of using remote sensing applications to monitor aerosol concentrations and movement provides future opportunities to leverage machine learning technologies to build predictive models with the goal of early forecasting and public health interventions. The Sentinel-5P satellite instrument measures the air quality, ozone, and Ultraviolet (UV) radiation, and can be used for climate monitoring, and forecasting. Available on this platform is the UV Aerosol Index (AI) product, a qualitative index that indicates the presence of elevated layers of aerosols in the atmosphere. In this paper, we used Google Earth Engine to monitor the transatlantic movement of this historic dust plume across the Sahara Desert and estimate the aerosol concentrations throughout June 2020. The flexibility of the platform enabled us to generate time series maps to visualize the movement of the Godzilla dust storm from the Sahara Desert across the ocean. The results obtained are relevant for effective planning and interventions to ameliorate the health threats associated with the movement of the dust plume. The outcome is useful for defining the relationship between aerosol concentrations, human health, and aquatic life.

Position information attention networks for explosive mobile phone classification

Abstract. There is a growing concern about public security, especially the discovery of explosives hidden in mobile phones during security checks. However, there is almost no public dataset of explosive mobile phones to study this topic. We contribute the first explosive mobile phone benchmark dataset for security screening, named explosive mobile phones x-ray image dataset, which will be publicly available. Note that explosive mobile phone classification is a typical class imbalance task. Although the number of explosive mobile phones is far smaller than the number of normal mobile phones, one missed phone can cause a huge loss of life and property. To accurately identify explosives hidden in mobile phones, we propose a module called position information attention module (PIAM). Benefiting from aggregating the position information encoded in networks along the channel and spatial domains, PIAM highlights informative features of explosives. In addition, PIAM combines with other networks effectively at a low cost, empowering them with the ability to identify important details. Furthermore, in the face of the class imbalance, we propose a sample-oriented coefficient called sample cost with an update rule. Extensive experimental results show that PIAM and sample cost significantly improve the performance of many excellent networks in explosive mobile phone classification.

Cut-and-connect of two antiparallel vortex tubes

Motivated by an early conjecture that vortex cut-and-connect plays a key role in mixing and production of turbulence, helicity and aerodynamic noise, the cross-linking of two antiparallel viscous vortex tubes via direct numerical simulation is studied. The Navier-Stokes equations are solved by a dealiased pseudo-spectral method with 64 cubed grid points in a periodic domain for initial Reynolds numbers Re up to 1000. The vortex tubes are given an initial sinusoidal perturbation to induce a collision and keep the two tubes pressed against each other as annihilation continues. Cross-sectional and wire plots of various properties depict three stages of evolution: (1) Inviscid induction causing vortex cores to first approach and form a contact zone with a dipole cross-section, and then to flatten and stretch; (2) Vorticity annihilation in the contact zone accompanied by bridging between the two vortices at both ends of the contact zone due to a collection of cross-linked vortex lines, now orthogonal to the initial vortex tubes. The direction of dipole advection in the contact zone reverses; and (3) Threading of the remnants of the original vortices in between the bridges as they pull apart. The crucial stage 2 is shown to be a simple consequence of vorticity annihilation in the contact zone, link-up of the un-annihilated parts of vortex lines, and stretching and advection by the vortex tube swirl of the cross-linked lines, which accumulate at stagnation points in front of the annihilating vortex dipole. It is claimed that bridging is the essence of any vorticity cross-linking and that annihilation is sustained by stretching of the dipole by the bridges. Vortex reconnection details are found to be insensitive to asymmetry. Modeling of the reconnection process is briefly examined. The 3D spatial details of scalar transport (at unity Schmidt number), enstrophy production, dissipation and helicity are also examined.
Fulde-Ferrell-Larkin-Ovchinnikov states and quantum oscillations in mesoscopic superconductors and superfluid ultracold Fermi gases

We have studied the distinctive features of the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) instability and phase transitions in two--dimensional (2D) mesoscopic superconductors placed in magnetic field of arbitrary orientation and rotating superfluid Fermi gases with imbalanced state populations. Using a generalized version of the phenomenological Ginzburg-Landau theory we have shown that the FFLO states are strongly modified by the effect of the trapping potential confining the condensate. The phenomenon of the inhomogeneous state formation is determined by the interplay of three length scales: (i) length scale of the FFLO instability; (ii) 2D system size; (iii) length scale associated with the orbital effect caused either by the Fermi condensate rotation or magnetic field component applied perpendicular to the superconducting disc. We have studied this interplay and resulting quantum oscillation effects in both superconducting and superfluid finite -- size systems with FFLO instability and described the hallmarks of the FFLO phenomenon in a restricted geometry. The finite size of the system is shown to affect strongly the conditions of the observability of switching between the states with different vorticities.
