A 22-year-old Indonesian woman was admitted through the emergency department with a 10-day history of fever associated with chills. Other medical history was unremarkable. On examination, she appeared ill; BP 95/60 mmHg, pulse 105/min, and temperature 39.5°C. Abdominal examination showed splenomegaly; examination of the heart, lungs, and nervous system was unremarkable. Initial investigations showed hemoglobin level of 9.0 g/dL, total leukocyte count 5000/μL with a normal differential, platelet count of 112,000/μL, and ESR of 66 mm/h. Blood chemistry, liver profile, and coagulations studies were within normal limits. Malaria parasite smear was negative, urine dipstick and microscopy were normal. Blood culture showed candidemia, but urine and stool cultures were negative. Chest and abdominal radiographs were normal. A tuberculin skin test was negative. Apart from splenomegaly, abdominal ultrasound was unremarkable. Although bone marrow aspiration and biopsy showed normal study, leishmaniasis was put in the differential diagnosis. Amphotericin B was started to cover the candidemia and the suspected leishmaniasis. On the 3rd admission day, the fever continued, and the patient developed abdominal distension with complete constipation and vomiting. Radiography of the abdomen and ECG was performed. Questions: 1. What do the X-ray and ECG show? 2. Which blood test would you recommend? 3. Spot the diagnosis based on the given images.
Associations between livestock keeping, morbidity, and nutritional status of children and women in low and middle-income countries: a systematic review.

Livestock keeping can positively influence nutritional status of populations and households through increased consumption of animal-source foods (ASF) and other indirect pathways, but can also adversely affect health by increasing the risk of diseases. We conducted a systematic review synthesizing the current state of knowledge on the associations between livestock keeping and infectious disease and nutritional status of under-five children and women of reproductive age in low- and lower middle-income countries (LMICs). A comprehensive search of 12 electronic databases and grey literature sources published from 1991 to the end of December 2020 was conducted. Investigations exploring relationships between livestock keeping and risk of infectious disease transmission and nutritional status were selected using pre-defined inclusion criteria. After screening and filtering of 34,402 unique references, 176 references were included in the final synthesis. Most (160/176, 90.1%) of the references included in the final synthesis were from sub-Saharan Africa (SSA) and Asia. About two out of every five (42%) studies reviewed showed that livestock production is associated with improved height-for-age Z scores (HAZ) and weight-for-length/height Z scores (WHZ), while close to a third (30.7%) with improved weight-for-age Z scores (WAZ). Similarly, livestock production showed a positive or neutral relationship with women's nutritional status in almost all the references that reported on the topic. Conversely, four-fifths (66/81, 79.5%) of the references reporting on infection and morbidity outcomes indicated that livestock keeping is linked to a wide range of infectious disease outcomes, which are spread primarily through water, food, and insects. In conclusion, in many LMIC settings, livestock production is associated with better nutritional outcomes but also a higher risk of disease transmission or morbidity among women and children.
A Jitter-Robust 40 Gb/s ADC-Based Multicarrier Receiver Front-End With 4-GS/s Baseband Pipeline-SAR ADCs in 22-nm FinFET

Demand for increased data rates in serial link transceivers calls for innovative architectures capable of overcoming impairments such as limited channel bandwidth (BW) and stringent jitter specifications. This article presents a receiver front-end (RXFE) architecture that supports multicarrier signaling to provide a ~3 $\times $ relaxation in clock jitter requirements. A total of 40 Gb/s data rate is supported by three 4-GS/s bands with baseband (BB) four-level pulse amplitude modulation (PAM4) and mid-band (MB) and high-band (HB) 16-state quadrature amplitude modulation (QAM16) on 4- and 8-GHz orthogonal carriers, respectively. The RXFE uses three per-band optimized continuous-time linear equalizers (CTLEs) to partially equalize the in-band channel loss and four-way time-interleaved 7-b pipelined-successive approximation register (SAR) analog-to-digital converters (ADCs). Tight band spacing is achieved with tolerable inter-channel interference (ICI) using resettable integrators in the receiver segments. Fabricated in a 22-nm fin field-effect transistor (FinFET), the proposed 40-Gb/s multicarrier RXFE can tolerate up to 1.6-psrms jitter and achieve a bit error rate (BER) < 10−5 operating over a channel with 20-dB loss at 10 GHz when combined with an off-chip one-tap digital ICI canceller. The ADC-based front-end achieves 3.05-pJ/bit power efficiency, including all the front-ends, ADC, and clocking power.
Limited frequency interval Gramian-based model reduction for generalised non-singular discrete time systems

A limited frequency interval Gramians-based model reduction technique for generalised non-singular discrete time systems is presented. The technique generalises the results of existing limited frequency interval Gramians-based model reduction (of discrete time systems) schemes to general non-singular discrete time systems. Numerical examples are also presented to illustrate the proposed technique.
Production of Nanopowders Using Nanosecond Electron Beam

Frequency nanosecond electron accelerators type URT has been developed for use in radiation technologies. The accelerator includes a thyratron, a pulse transformer and a semiconductor opening switch. The accelerating voltage is up to 0.9 MV, FWHM pulse length is up to 60 ns, and the repetition rate is up to 250 Hz. A metal ceramic cathode, which is used in the accelerator, provides an electron beam cross section up to 16 cm in diameter or rectangular with the dimensions of 45 * 5cm2 at a maximum density of the pulse current equal to 2 A/cm2. Thus, a family of nanosecond electron accelerators has been developed for use in radiation technologies applied to layers up to 0.4 g/cm2 thick, such as production of nanopowders from gas and liquid precursors. Experiments on the irradiation of silver nitrate solutions in various liquids by a URT-0.5 accelerator facilitated the development of technology for producing silver nanopowders (NPs). The powder yield and particle size as a function of the irradiation mode has been established. An increase in the adsorbed dose results in an increased powder yield; however, the particle size decreases and the powder agglomeration rate increases. Therefore, the targeted production of silver NPs with a mean particle size in the range of 90–1100 nm is possible. Besides to produce TiO2 and SiO2 NPs the gas precursors were used.
Three-phase harmonic load flow in frequency and time domains

A hybrid method in the time and frequency domains has been developed for the analysis of the harmonic distortion in power systems. This method is more complete than others reported in the literature and it allows both balanced and unbalanced systems to be considered. The linear elements of a network are modelled in the frequency domain while the nonlinear elements are modelled in the time domain, which permits consideration of all topologies and configurations. Acceleration techniques are used for finding the steady state in time-domain methods. Linear and nonlinear loads can be specified in terms of power by integrating a three-phase load-flow algorithm for the fundamental frequency with a hybrid algorithm for the harmonic interaction analysis. The proposed method tries to solve the present problems to study harmonic-distortion propagation in a power system. The integration of two complex and different algorithms is done here for the first time and offers great possibilities for power-systems analysis.

Effects of Variable Droplet Growth Histories on Droplet Size Distributions. Part I: Theory

Abstract A theoretical framework is developed that permits estimation of the effects of fluctuating supersaturation on the development of cloud droplet size spectra. The studies focus on the role of turbulent fluctuations in vertical wind and in the microphysical environments in which droplets grow, and represent the effects of droplets mixing together that have encountered different trajectories through the cloud. It is contended that the effects can be analyzed in terms of two contributions to the variance in supersaturation history, one dependent on the average microphysical environment (specifically, integral radius) of the near environment in which a droplet grows, and the other dependent on the correlation between the integral radius and the updraft along the droplet trajectory. Variations in the possible trajectories that all end at a given point (and so form the droplet spectrum there) are used to estimate the possible widths of droplet spectra, and methods of testing these predictions using exper.
A generalization of outer parallel sets of a convex set

An outer parallel set is formed by adding outer normals of fixed length to the boundary points of a convex set. In this paper the length of the outer normals varies as a function of the direction. This construction yields a geometric interpretation of the dual quermassintegrals of Lutwak and bounds on certain mixed volumes. An inequality of Firey will follow from one of the mixed volume bounds.

A Coupled Free Wake - CFD Method for The Simulation of Helicopter Rotor Flow

A new coupled wake  CFD method is used to include realistic wake effects in CFD solutions for rotor flow in hover. The analytical method for predicting hovering rotor wake is described to investigate the motion of the helical tip vortex. Beginning with the generalized wake model, a semi-empirical correction for the vortex core effect on rotor wake is made. Then on the condition of circulation and wake geometry convergence, the free wake calculation is accomplished. Finally, EulerNavierStokes equations are solved for transonic rotor flow employing Jameson's finite-volume explicit Runge-Kutta time-stepping scheme. The results are compared with the respective references and experimental data.
Near room-temperature magnetoresistance effect in double perovskite La2NiMnO6

Near room-temperature magnetoresistance (MR) effect in ferromagnetic semiconductor La2NiMnO6 has been reported. The magnetic field dependent MR curve exhibits two distinct regions: the low-field MR which shows a rapid increase in an applied field within 200 Oe and the high-field MR which shows a relatively slow increase with the field increasing (more than 200 Oe). Based on the analyses of magnetic and electronic properties, we suggest that the low-field MR comes from the increased electron tunneling probability accompanied by the alignment of ferromagnetic domains under external field and the high-field MR is due to the suppression of scattering from the spin defects arising from the Ni/Mn antisite disorders.

Network of Interaction among Enterobacter Species and Klebsiella Pneumonia Clinical Isolates and the Antibiotic Resistance Pattern at Cape Coast

Urgent surveillance is required to provide the needed information for the containment of multidrug resistant (MDR) Enterobacteriaceae. The objective was to examine the antibiotic-resistant patterns among the clinically isolated Enterobacter species and Klebsiella pneumonia from the outpatient department of the University of Cape Coast from 2014 to 2020. The cultured isolates were Gram-stained for morphological and biochemical tests. Antibiotic susceptibility tests for the K. pneumonia and Enterobacter spp were done using the modified Kirby-Bauer diffusion technique. A double-disk synergy antibiotic test using cefotaxime, amoxicillin/clavulanic acid and ceftazidime antibiotic test were used to identify extended-spectrum beta-lactase (ESBL) and MDR among the isolates. The network of interactions between bacteria isolates and resistant types and the pattern of interaction of K. pneumonia (in the resistant-10 group) and Enterobacter spp (resistant-12) and the various antibiotics tested; was performed using Cytoscape version 3.8. 2 software. The data are presented in percentage and statistical significance between MDR and extensively drug resistant (XDR) compared with Chi-square test. K. pneumonia formed clustering network with other bacteria isolates around resistant type 10 (resistant-10) and Enterobacter spp around resistant type 12 (resistant-12). The interactions (edges) of bacteria isolates and resistant types (nodes) were unique for Staphylococcus saprophyticus with Proteus mirabilis which exhibited two patterns of interactions (resistant-10 and resistant-12), connecting the two resistant types among the bacteria isolates. The interactive network patterns of Enterobacter spp and the various antibiotics were different from the interaction patterns for K. pneumonia. The K. pneumonia isolates were highly resistance to cefuroxime 2/3 (66.67%) and ampicillin 2/3 (66.67%) in the year 2020. Enterobacter spp on the other hand were highly resistance to tetracycline 16/20 (80.00%) in 2014 and ceftriaxone 5/9 (55.56%), levofloxacin 5/9 (55.56%), ceftazidime 5/9 (55.56%) and gentamycin 5/9 (55.56%) in 2020. Chi-square analysis showed a high significant difference of χ2 = 11.87, p=0.0006 and χ2 = 7.789, p=0.0053 between MDR and XDR Enterobacter spp isolates in 2014 and 2020 respectively. Early detection, constant monitoring and control practices and policies that prevent the misuse or overuse of these antibiotics are required to slow down the rapid development of resistance to Enterobacter spp and K. pneumonia in Cape Coast.
Photoinduced conductivity in tin dioxide thin films

The effects of ultraviolet light irradiation on the conducting properties of SnO2−x thin films grown epitaxially on TiO2 or Al2O3 single-crystal substrates are studied at room temperature. A large increase in conductivity by two to four orders of magnitude is observed with light irradiation in an inert atmosphere and remains after the light is removed. The high-conducting state reverts to the original low-conducting state by exposing it to oxygen gas. These reversible phenomena are ascribed to the desorption and adsorption of negatively charged oxygen species at the grain boundaries, which critically change the mobility of electron carriers already present inside grains by changing the potential barrier height at the grain boundary. The UV light irradiation provides us with an easy and useful route to achieve a high-conducting state even at low carrier density in transparent conducting oxides and also to draw an invisible conducting wire or a specific pattern on an insulating film.
AMMF: Attention-Based Multi-Phase Multi-Task Fusion for Small Contour Object 3D Detection

Recently significant progress has been made in 3D detection. However, it is still challenging to detect small contour objects under complex scenes. This paper proposes a novel Attention-based Multi-phase Multi-task Fusion (AMMF) that uses point-level, RoI-level, and multi-task fusions to complement the disadvantages of LiDAR and camera, to solve this challenge. First, at the feature extraction phase, AMMF uses the Low and High-level Fusion with Matching Attention (LHF-MA) and efficient FPN (eFPN) to perform point-level fusion for cross sensors and single sensor, respectively. Instead of merging each level and using expensive 3D CNN like other methods, LHF-MA fuses low-level spatial location and high-level contextual feature of 2D CNN customized feature extractors and ignores the fusion of middle levels, reducing the computational cost. Then, at the proposal generation phase, Progressive Proposal Fusion (PPF) with learned attention map is used to perform coarse-to-fine RoI-level fusion, instead of only combining coarse-grained features at high-level of network. PPF using progressively increasing IoU thresholds could avoid overfitting and improve the performance. Note that the matching attentions and learned attention maps are utilized to weigh the priority of different sensors. Moreover, to solve the sparseness of point-wise fusion between LiDAR BEV and RGB image, AMMF uses multi-task fusion that generates pseudo-LiDAR from camera by depth estimation task, to guide this point-wise fusion. Finally, AMMF performs excellently for detecting small contour objects like pedestrians, cyclists, and distant cars. On the KITTI, AMMF finishes 3.62% improvements in the moderate instance for pedestrians. It achieves a 2.21% improvement in the >50 instance of LEVEL_2 level for vehicle on the Waymo Open Dataset. And AMMF is further verified on our customized dataset consisting of challenging scenarios like strong illumination and heavy shadow cases.
Correction of Humidity Bias for Vaisala RS80-A Sondes during the AMMA 2006 Observing Period

Abstract During the African Monsoon Multidisciplinary Analyses (AMMA) program, which included a special observing period that took place over West Africa in 2006, a major effort was devoted to monitor the atmosphere and its water cycle. The radiosonde network was upgraded and enhanced, and GPS receivers deployed. Among all sondes released in the atmosphere, a significant number were Vaisala RS80-A sondes, which revealed a significant dry bias relative to Vaisala RS92 (a maximum of 14% in the lower atmosphere, reaching 20% in the upper levels). This paper makes use of a simple but robust statistical approach to correct the bias. Comparisons against independent GPS data show that the bias is almost removed at night, whereas for daytime conditions, a weak dry bias (5%) still remains. The correction enhances CAPE by a factor of about 4 and, thus, becomes much more in line with expected values over the region.
