OMP-based hybrid precoding and SVD-based hybrid combiner design with partial CSI for massive MU-MIMO mmWave system

Millimeter-wave (mmWave) communications have been regarded as a key technology for the next-generation cellular systems since the huge available bandwidth can potentially provide the rates of multiple gigabits per second. Conventional precoding and combining techniques are impractical at mmWave scenarios due to manufacturing costs and power consumption. Hybrid alternatives have been considered as a promising technology to provide a compromise between hardware complexity and system performance. In this paper, we propose a hybrid precoder/combiner design through a hierarchical strategy evolving three stages. In the first stage, we incorporate the use of a low complexity and low size discrete Fourier transform based-codebook, which greatly reduces the needs of channel side information of our proposal. The hybrid precoder includes (i) a compress sensing technique, orthogonal matching pursuit(OMP), to take advantage of the channel sparsity at the beamforming selection procedure, (ii) the classical MMSE linear filter to deal with interference system, and (iii) the eigenvectors of the residual user channel to increase their channel gain. On the other hand, the hybrid combiner uses a low complex beamforming selection algorithm and the eigenvectors of their own residual channel. Numerical results in terms of BER and sum-rate illustrate the performance improvements resulting from our proposal in relation to other hybrid precoders/combiners.
Sub-Terahertz Antenna Array Packaged in Bio-Compatible Polymer for Fully-Passive Subdermal Sensing

Sub-terahertz (sub-THz) systems are ideal for implants that require continuous high-resolution sensing and wireless communications for diagnostics. There is also a need for these systems to be small, cost-effective, and of bio-compatible material. Here, we present an antenna array that is capable of sub-THz operation (0.063-0.212THz) and is small in size with a $\mathbf{5\times 5}$ configuration $\mathbf{(2.85{mm}\times 2.85{mm})}$, or a $\mathbf{3\times 3}$ array $\mathbf{(1.7mm\times 1.7mm)}$. Furthermore, the antenna uses a low-cost polymer as substrate and superstrate. This ensures efficient high frequency operation and bio-compatible packaging while maintaining a profile of 0.38mm. The array has dual-linear polarization and achieves a 3.4:1 contiguous impedance bandwidth at broadside with a voltage standing wave ratio (VSWR) $\mathbf{< 2}$ across the entire band under a 0.07mm epidermis layer. Similarly, the antenna achieves a 3.2:1 bandwidth with VSWR $\mathbf{< 2}$ for a 0.015mm layer of stratum corneum. Full-wave simulation of the array demonstrates $\mathbf{>70 \%}$ efficiency across the entire band for both conditions. A 60dB polarization purity is also achieved.
Enhancing Bandwidth and Back-Off Range of Doherty Power Amplifier With Modified Load Modulation Network

This article presents a novel methodology for designing a broadband Doherty power amplifier (DPA) with extended output power back-off (OBO) range. A modified load modulation network (LMN) is proposed to enhance the OBO range and the bandwidth of the DPA simultaneously. Analysis is conducted to explore the relationship between the proposed LMN parameters and the broadband performance under various OBO levels. Generalized design formulas of the LMN parameters are then introduced to offer the broadband solution for arbitrary current ratios and OBO levels. An asymmetric DPA is demonstrated and implemented with gallium nitride (GaN) transistors using the proposed approach. The fabricated DPA operates from 1.4 to 2.5 GHz with 9-dB OBO range. The measured drain efficiency reaches 61%–75.5% at saturation and 44.6%–54.6% at 9-dB OBO within the operating bandwidth. When driven by a 60-MHz modulated signal with 9-dB peak-to-average power ratio (PAPR), the fabricated DPA attains 47.4%–53.5% average drain efficiency and better than −45.5-dBc adjacent channel leakage ratio (ACLR) after digital predistortion.
Performance, carcass and internal organs characterizes of broiler chickens with phytase supplementation from Burkholderia sp. Strain HF.7

Feed formulation with phytase supplementation is an innovation in the feed industry to improve monogastric feed quality without increasing production costs. This study aims to determine the carcass weight of broilers and the percentage of internal organs by providing various feeds, including those supplemented with phytase in phytase units (FTU) from Burkholderia sp. strain HF.7. A completely randomized experimental design was used in this study, using 108 broilers for five weeks of maintenance in three treatments with six replicas, each replica consisting of six broilers. The experimental feed given to broilers was basal feed without phytase supplementation (P1), basal feed + 750 FTU phytase (P2) and commercial feed (P3), each with the category of starter phase and finisher phase. Carcass weight and percentage of organs in broilers (liver, heart, gizzard, and lymph) were measured in each treatment unit. The results showed that broilers that consumed phytase supplemented feed had a higher carcass weight with a lower feed conversion value than broilers fed basal feed without phytase. These findings also indicate that the addition of phytase from Burkholderia sp. HF.7 strain at 750 FTU/kg feeds does not interfere with the organs of broilers' physiological function because of no increase in the percentage of the liver, heart, gizzard, and lymph.
Efficient cooperation of chloroplasts and mitochondria enhances ATP and sucrose production

Efficient photosynthesis requires a balance of ATP and NADPH production/consumption in chloroplasts as the linear electron flow generates a higher NADPH/ATP ratio than that is consumed by the Calvin-Benson-Bassham cycle. Recent works suggested that ATP importation into mature chloroplasts of Arabidopsis thaliana is negligible, and therefore the exportation of reducing equivalents from chloroplasts is important for balancing stromal ATP/NADPH ratio. Here we showed that the overexpression of purple acid phosphatase 2 on the outer membranes of chloroplasts and mitochondria can streamline the production and consumption of reducing equivalents in these two organelles, respectively. A higher capacity of consumption of reducing equivalents in mitochondria can indirectly help chloroplasts to balance the ATP/NADPH ratio in stroma and recycle NADP+, the electron acceptors of the linear electron flow. A higher rate of ATP and NADPH production from the linear electron flow, a higher capacity of carbon fixation by the Calvin-Benson-Bassham cycle and a greater consumption of NADH in mitochondria, enhance photosynthesis in the chloroplasts, ATP production in the mitochondria, sucrose synthesis in the cytosol, and eventually boosting plant growth and seed yields in the overexpression lines. One-Sentence Summary This study demonstrates the importance of chloroplast-mitochondria cooperation in redox balance and illustrates that an optimized function of mitochondria can enhance the efficiency of photosynthesis.
MARS-Net: Deep learning-based segmentation pipeline for profiling cellular morphodynamics from multiple types of live cell microscopy

Quantitative studies of cellular morphodynamics rely on extracting leading-edge velocity time-series based on accurate cell segmentation from live cell imaging. However, live cell imaging has numerous challenging issues about accurate edge localization. Here, we develop a deep learning-based pipeline, termed MARS-Net (Multiple-microscopy-type-based Accurate and Robust Segmentation Network)
Expertise and impediments in pressure ulcer nursing care – A cross sectional study

Introduction: Pressure ulcer (PU) continues to remain a challenge even though it is a preventable condition and sufficient progress being accomplished in medical field for its prevention and management. The role of nursing staff in PU care is of paramount importance with far reaching consequences. Objective: In the present study we aim to evaluate knowledge on pressure ulcer prevention & care amidst nursing professionals working in direct care with adult and geriatric patients. Methods: It was a cross-sectional study. Pieper ́s Pressure Ulcer Knowledge Test (PUKT) was used to assess the knowledge by observing the responses on ulcer assessment, wound assessment and PU prevention. Results: A total of 239 research participants completed the study. The mean of total correct response was 28.46 ± 6.5 with the individual mean for correct response to questions related with ulcer, wound and prevention being 4.02 ± 1.5, 3.81 ± 1.4 and 20.71 ± 4.6 respectively. Maximum correct responses were observed for questions related with prevention of PU. Nursing professionals involved in routine care of patients performed better in all the aspects of knowledge test. The most common barrier identified were lack of sufficient time and inadequate staff followed closely by lack of training/ resources/ equipment/ guidelines. Conclusion: The identification of deficient areas can guide strategic planning for dissemination and adoption of preventive measures which could be adopted by entire interdisciplinary wound care team.
Transposable element variants and their potential adaptive impact in urban populations of the malaria vector Anopheles coluzzii

Anopheles coluzzii is one of the primary vectors of human malaria in sub-Saharan Africa. Recently, it has spread into the main cities of Central Africa threatening vector control programs. The adaptation of An. coluzzii to urban environments partly results from an increased tolerance to organic pollution and insecticides. Some of the molecular mechanisms for ecological adaptation are known, but the role of transposable elements (TEs) in the adaptive processes of this species has not been studied yet. As a first step toward assessing the role of TEs in rapid urban adaptation, we sequenced using long reads six An. coluzzii genomes from natural breeding sites in two major Central Africa cities. We de novo annotated TEs in these genomes and in an additional high-quality An. coluzzii genome, and we identified 64 new TE families. TEs were nonrandomly distributed throughout the genome with significant differences in the number of insertions of several superfamilies across the studied genomes. We identified seven putatively active families with insertions near genes with functions related to vectorial capacity, and several TEs that may provide promoter and transcription factor binding sites to insecticide resistance and immune-related genes. Overall, the analysis of multiple high-quality genomes allowed us to generate the most comprehensive TE annotation in this species to date and identify several TE insertions that could potentially impact both genome architecture and the regulation of functionally relevant genes. These results provide a basis for future studies of the impact of TEs on the biology of An. coluzzii.
Wandering minds, sleepy brains: lapses of attention and slow waves in wakefulness

Attentional lapses are ubiquitous and can negatively impact performance. They correlate with mind wandering, or thoughts that are unrelated to ongoing tasks and environmental demands. In other cases, the stream of consciousness itself comes to a halt and the mind goes blank. What is happening in the brain that leads to these mental states? To understand the neural mechanisms underlying attentional lapses, we cross-analysed the behaviour, subjective experience and neural activity of healthy participants performing a task. Random interruptions prompted participants to indicate their mental states as task-focused, mind-wandering or mind-blanking. High-density electroencephalography revealed the occurrence of spatially and temporally localized slow waves, a sleep-like pattern of neural activity. These slow waves accompanied behavioural markers of lapses and preceded reports of mind wandering and mind blanking. Furthermore, the location of slow waves distinguished sluggish versus impulsive behaviours, mind wandering versus mind blanking. Our results suggest attentional lapses share a common physiological origin: the emergence of local islets of sleep within the awake brain.

Impact of darknet market seizures on opioid availability

Opioids, including the highly potent synthetic opioids fentanyl and carfentanil, are commonly sold on illicit cryptomarkets or Tor darknet markets. Data collected throughout 2019 from 12 large darknet markets that sold opioids enabled observation of the impact of law enforcement seizures and voluntary or scam market closures on the availability of fentanyl and other opioids. Trends in opioid and fentanyl availability before and after law enforcement interventions indicate whether market operators and sellers are deterred and whether market closures lead to displacement, dispersal or substitution. Evidence of all of these outcomes was present in both descriptive and trend analyses, although most effects were short lived. Market closures, especially law enforcement seizures, reduced the availability of opioids, in particular fentanyl, as well as increasing prices and displacing vendors to other markets. Market closures also led vendors to substitute fentanyl for other opioids or other illicit drugs.
Nomogram Model for Prediction of Portal Vein Thrombosis in Patients with Liver Cirrhosis After Splenectomy: A Retrospective Analysis of 2 Independent Cohorts

Background The aim of this study was to establish and validate an easy-to-use nomogram to predict portal vein thrombosis (PVT) in patients with cirrhosis after splenectomy and to test its predictive ability. Material/Methods This retrospective study included 315 patients with cirrhosis who underwent splenectomy at 2 high-volume medical centers. The least absolute shrinkage and selection operator (LASSO) regression method was used to select the predictors in the training cohort, and multivariable logistic regression analysis was performed to establish the predictive nomogram model. We determined the prediction value of the nomogram by the area under the receiver operating characteristic curve (AUROC), the calibration curve, and decision curve analysis. Finally, the applicability of the nomogram was internally and independently validated. Results The predictors of PVT included portal vein diameter, splenic vein diameter, body mass index, and platelet count. Based on the clinical and radiomic models, the nomogram had good predictive efficiency for predicting PVT in patients with cirrhosis after splenectomy, with an AUROC of 0.887 (0.856 in internal validation and 0.796 in independent validation). The decision curve analysis revealed that the nomogram had good clinical application value. Conclusions We successfully developed an easy-to-use nomogram to predict the probability of PVT in patients with cirrhosis after splenectomy. The nomogram can help clinicians make timely, individualized clinical decisions for PVT in patients with cirrhosis after splenectomy.
Effects of Music Therapist Positioning within Patient-Preferred Live Music on Affect, Pain, and Trust

Background: Although patient-preferred live music (PPLM) can be an effective music therapy intervention for mood and pain with hospitalized adult medical patients, there is a lack of literature concerning therapist positioning within PPLM interventions. Objective: The purpose of this randomized pilot study was to determine the effects of therapist positioning within PPLM on positive and negative affect, pain, and trust in the therapist with adults on a cardiovascular unit. Methods: Participants (N=27) were randomly assigned to one of three single-session conditions: PPLM delivered with the therapist sitting, PPLM delivered with the therapist standing, or wait-list control. Positive and negative affect were measured with the Global Mood Scale, pain was measured with a 10-point Likert-type scale, and trust in therapist was measured with the Wake Forest Physician Trust Scale. Results: Results indicated no significant between-group difference in positive affect, negative affect, or pain. Control participants tended to have slightly lower posttest positive affect mean scores and slightly higher posttest negative affect and pain scores, indicating that both PPLM conditions had more favorable results than the control condition. Regardless of therapist positioning, descriptive statistics for affect and pain were more favorable after PPLM. Concerning trust in the therapist, there was no difference between the sitting and standing conditions. Conclusion: Regardless of the therapist’s positioning, a single PPLM session can be an effective intervention for immediately improving positive and negative affect and pain for adult inpatients on a cardiovascular unit. Concluding this pilot study are limitations, implications for clinical practice, and recommendations for future investigation.
Microbial biodiversity in arable soils is affected by agricultural practices

Abstract The aim of the study was to examine the differences in microbial community structure as a result of agricultural practices. Sixteen samples of cultivated and the same number of non-cultivated soils were selected. Gel bands were identified using the GelCompar software to create the presence-absence matrix, where each band represented a bacterial operational taxonomic unit. The data were used for principal-component analysis and additionally, the Shannon- Weaver index of general diversity, Simpson index of dominance and Simpson index of diversity were calculated. Denaturing gradient gel electrophoresis profiles clearly indicated differentiation of tested samples into two clusters: cultivated and non-cultivated soils. Greater numbers of dominant operational taxonomic units (65) in non-cultivated soils were noted compared to cultivated soils (47 operational taxonomic units). This implies that there was a reduction of dominant bacterial operational taxonomic units by nearly 30% in cultivated soils. Simpson dominance index expressing the number of species weighted by their abundance amounted to 1.22 in cultivated soils, whereas a 3-fold higher value (3.38) was observed in non-cultivated soils. Land-use practices seemed to be a important factors affected on biodiversity, because more than soil type determined the clustering into groups.

The interaction between both studied factors brought about significant increases in all mentioned traits except number of spikes plant-1.
The impact of international ﬁnancial institutions on small and medium enterprises: the case of EIB lending in Central and Eastern Europe

Views presented in the paper are those of the authors only and do not necessarily represent the views of the European Investment Bank (EIB) or the Bank of Slovenia. Abstract Does IFI funding provide support to SMEs receiving such funding? We assess the impact of funding by the European Investment Bank (EIB) on the performance of 5,223 SMEs in eight countries of Central and Eastern Europe (CEE) during 2008-2014. Our results, derived from propensity score matching and diﬀerence-in-diﬀerence estimation exercises, indicate that EIB lending has a positive eﬀect on employment, revenues and proﬁtability. This positive eﬀect holds irrespective of the economy entering a prolonged crisis or a seeing a recovery in the years following EIB funding. Overall, our results provide support to the view that IFI funding makes a diﬀerence in a period characterized by ﬁnancial and economic turmoil.
