Hepatic granuloma mimicking recurrent lymphoma on 18F-FDG PET/CT in a patient with primary mediastinal diffuse large B-cell lymphoma

18F-Flurodeoxyglucose (FDG) PET/CT has been considered the modality of choice in detecting, staging, restaging and following-up with lymphoma patients. However, it has an uncertain role in differentiating hepatic lymphomatous relapse from other granulomatous diseases such as in candidiasis or sarcoidosis. Therefore, it is important to correlate the imaging findings with other modalities such as ultrasound, CT scan, MRI, and histology to direct the diagnosis and treatment. We present a case of a 33-year-old woman with large B-cell lymphoma in complete remission following treatment presenting with neutropenic fever following her final cycle of chemotherapy. Ultrasound of the abdomen and enhanced CT scan of the abdomen and pelvis were negative. The FDG PET/CT scan showed multiple FDG-avid hypodense hepatic lesions that were suggestive either of lymphoproliferative involvement or nonmalignant process. However, MRI of the abdomen performed four days later was suggestive of an infectious process, rather than a lymphoproliferative disorder. A subsequent CT-guided biopsy of a hepatic lesion showed granulomatous inflammation, with no evidence of malignancy or Tuberculosis. The patient was started on Caspofungin followed by Fluconazole. After 5 weeks, the clinical condition resolved, and the subsequent FDG PET/CT showed complete resolution of the FDG-avid multiple hepatic lesions.
An improved transistor noise equivalent circuit model for silicon‐on‐insulator transistors considering the frequency dispersion effect

In this paper, an improved transistor equivalent circuit noise model is proposed. This model takes the frequency dispersion effects into account and modified the induced gate current source (Ig) equation based on the classical Van der Ziel noise model. First, the conductance at Vd = 0 V (gd0) is derived from DC bias condition, and the accuracy of channel thermal noise (Id) is verified. Then, by analyzing the physical structure of the silicon‐on‐insulator (SOI) transistor, an equivalent lumped‐parameter circuit model is established. The element initial values are extracted based on the measured S‐parameters. Then, the parameters in the Ig equation are obtained through noise circle simulation in comparison with measurement data. In contrast to existing models, the frequency dispersion effect is analyzed and modeled using a three‐order polynomial. The results show that with respect to the traditional noise model, the noise circle's root‐mean‐square error of this work is decreased from 23.16 to 1.55.
Research and implementation of a fabric printing detection system based on a field programmable gate array and deep neural network

In this paper, aiming at the problems of difficult positioning, slow speed and low precision of digital printing, a detection system suitable for textile printing positioning is proposed and designed. This detection system innovatively combines a neural network and field programmable gate array (FPGA) to realize rapid and accurate positioning of printing. In the neural network part, this paper selects the backbone network Darknet19 of YOLOv2 as the backbone network, and under the premise of ensuring a certain detection accuracy, the network model is pruned and quantified to make it suitable for deployment on the embedded device FPGA. In addition, before the network training, this paper optimizes the candidate boxes by introducing k-means clustering to customize the analysis of the fabric print dataset to improve the detection accuracy. In the FPGA part, this paper optimizes the architecture on the FPGA side in two parts: data computation and data transmission. In terms of computational optimization, parallel optimization of the neural network is performed by combining FPGA optimization methods, such as pipeline and unroll. In terms of transmission optimization, we use a double-buffered design to ping-pong in the input and output modules to overlap the latency, and then use multi-port transmission to improve the overall bandwidth utilization and reduce the transmission latency caused by on-chip and off-chip interactions. The experimental results show that the detection system combining the neural network and FPGA can effectively position fabric prints and meet the needs of real-time. The design scheme has lower power compared to the graphics processing unit and is faster compared to the central processing unit.
Assessment of Microsatellite Markers (SSRs) For Genetic Diversity in Asparagus Officinalis L. And Allied Species

The present study was hypothesized to evaluate a set of SSRs for the assessment of genetic variations in Asparagus officinalis L. and their allied species. Nine genic SSR markers were especially developed for Asparagus genome and employed for DNA profiling studies of Asparagus species. These SSRs markers have revealed the allelic polymorphism ranging from 1.0 to 2.0. Allele frequency was found highest for psbD-trnL (1.0), petB (1.0) and AG7 (1.0), while it was lowest for ZHD1 (0.1). Polymorphism Information content (PIC) was highest for TC7 (0.9) while it was lowest (0.0) for psbD-trnL, petB and AG7 respectively. The genetic similarity coefficients were found to range from 0.42 to 1.0. The UPGMA clustering algorithm based on SSRs data have clustered Asparagus species into 4 groups (I, II, III & IV) indicating Asparagus officinalis (L.) cultivars and allied species in the first clade, while Asparagus officinalis (L.) ‘Gersengum’, Asparagus densiflorus (Kunth) Jessop, and Asparagus racemosus willd. were clustered in separate clades respectively. The present study has endorsed the origin status of Asparagus officinalis and their allied species. A. officinalis cultivars and other allied Asparagus species are clustered in separate clades, and it was revealed that they have monophyletic origin. It was established that SSRs markers could be informative markers for the differentiation of Asparagus officinalis cultivars, and their allied Asparagus species. Bangladesh J.

Creating multi-layered structures with freestanding parts in SU-8

This paper reports on a new method to create multi-layered structures with freestanding parts in SU-8. Examples of such structures are beams partially resting on a post or microchannels. The method, based on high-absorption UV light with a wavelength of 313 nm in SU-8, is fast, uses only traditional micromachining equipment and requires very few processing steps. It is well suited for thin freestanding layers (<15 µm). Furthermore, a variant of a method that uses a built-in UV blocking layer to enable freestanding structures is described in detail. This method has a broader application range in terms of the thickness of the freestanding parts. Both methods are applied to the fabrication of optical fiber clamps.
The Ice Core Gas Age‐Ice Age Difference as a Proxy for Surface Temperature

Ice cores provide detailed records of past climate change. Water stable isotopes are the most commonly used ice core climate proxy, but their quantitative interpretation remains challenging. Here, I argue that the gas age‐ice age difference (Δage) is a powerful proxy for past surface temperature. An analytical framework is derived that directly links past temperature to firn properties that can be reliably reconstructed (Δage, lock‐in depth). The framework is calibrated using both present‐day spatial patterns and last glacial maximum temperatures reconstructed via borehole thermometry. The usefulness of the method is demonstrated using three case studies from Greenland and Antarctic ice cores. The calibration suggests that several firn densification models, with the possible exception of the Herron‐Langway model, have insufficient sensitivity to accumulation rates. This low sensitivity, in combination with large amplitude temperature forcing, can explain historical difficulties of densification models in simulating ice age firn thickness in East Antarctica.
Using a distributed hydrologic model to evaluate the location of Urban development and flood control storage

A physics-based, distributed hydrologic model (Vflo) was used to evaluate the effects of urbanization and detention storage on watershed stream flows with grid cells as small as 0.09 km2 (22 acres). The analysis was performed for the Little Cypress Creek watershed in Houston, Texas. Hypothetical development and flood mitigation scenarios in the upstream, midstream, and downstream portions of the creek were analyzed for their impacts on peak flows for the 100-year design storm. Local ponds and regional reservoirs were compared for their ability to bring downstream flows back to existing conditions at all points along the creek. Analysis showed that downstream flows would be most effectively mitigated when storm water detention volumes and release rates are imposed with an awareness of locations relative to watershed headwaters or a referenced outlet point. This is in contrast to many existing policies that are uniformly applied across a watershed.
Through lifetime monitoring of solder joints using acoustic micro imaging

Purpose – The purpose of this paper is to evaluate the application of an acoustic micro‐imaging (AMI) inspection technique in monitoring solder joints through lifetime performance and demonstrate the robustness of the monitoring through analysis of AMI data.Design/methodology/approach – Accelerated thermal cycling (ATC) test data on a flip chip test board were collected through AMI imaging. Subsequently, informative features and parameters of solder joints in acoustic images were measured and analysed. Through analysing histogram distance, mean intensity and grey area of the solder joints in acoustic images, cracks between the solder bump and chip interface were tracked and monitored. The results are in accord with associated Finite Element (FE) prediction.Findings – At defective bumps, the formation of a crack causes a larger acoustic impedance mismatch which provides a stronger ultrasound reflection. The intensity of solder joints in the acoustic image increase according to the level of damage during th.
A prospective study of clinicoepidemiology, metabolic and hormonal profile of women with hirsutism in Konaseema region of Andhra Pradesh

Background: Hirsutism is defined as presence of excess coarse hairs appear in male pattern in women.There is various aetiology of hirsutism like Idiopathic hirsutism, PCOS, androgen secreting ovarian tumours, menopause, CAH, Cushing’s syndrome, drugs which increases testosterone level, insulin resistance and tumour secreting androgen. We have designed present study with an aim to study the clinicoepidemiology, metabolic and hormonal profile of women with hirsutism in Konaseema region of Andhra Pradesh.Methods: All patients with hirsutism attending gynaecology outpatient department were selected for study based on inclusion and exclusion criteria. After that patient were examined clinically, BMI was calculated for each patient. Patients were clinically evaluated for signs of excess androgen secretion, Cushing syndrome, metabolic syndrome and hyperprolactinemia. Modified Ferriman-Gallwey scoring system was used for evaluating and quantifying hirsutism.Results: The mean Fasting plasma insulin12.42±2.41 (mIU/dl), the mean of HOMA-IR was 3.14±1.18. The mean value of dehydroepiandrosteronesulphate (DHEAS) 355.78±15.41 mcg/dl. There was statistically significant reduction in modified Ferriman-Gallwey scoring in before and after treatment (12.38± 1.55 vs. 9.62±1.6), the p value was 0.00001. The number of patients with menstrual irregularities were reduced from 63.3% to 20% after treatment and this difference is statistically significant (p=0.04). Conclusions: Hirsutism is associated with insulin resistance and DHEAS concentration was high. Modified Ferriman-Gallwey score was significantly reduced and there was significant weight loss and improvement in menstrual irregularities after treatment.
Impacts of Aerosol Loading in the Hindu Kush Himalayan Region Based on MERRA-2 Reanalysis Data

The impacts of climate change have severely affected geosphere, biosphere and cryosphere ecosystems in the Hindu Kush Himalayan (HKH) region. The impact has been accelerating further during the last few decades due to rapid increase in anthropogenic activities such as modernization, industrialization and urbanization, along with energy demands. In view of this, the present work attempts to examine aerosol optical depth (AOD) over the HKH region using the long-term homogeneous MERRA-2 reanalysis data from January, 1980 to December, 2020. The AOD trends are examined statistically with student’s t-test (t). Due to a vast landmass, fragile topography and harsh climatic conditions, we categorized the HKH region into three sub-regions, namely, the northwestern and Karakoram (HKH1), the Central (HKH2) and the southeastern Himalaya and Tibetan Plateau (HKH3). Among the sub-regions, the significant enhancement of AOD is observed at several potential sites in the HKH2 region, namely, Pokhara, Nainital, Shimla and Dehradun by 55.75 × 10−4 ± 3.76 × 10−4, 53.15 × 10−4 ± 3.94 × 10−4, 51.53 × 10−4 ± 4.99 × 10−4 and 39.16 × 10−4 ± 4.08 × 10−4 AOD year−1 (550 nm), respectively, with correlation coefficients (Rs) of 0.86 to 0.93. However, at a sub-regional scale, HKH1, HKH2 and HKH3 exhibit 23.33 × 10−4 ± 2.28 × 10−4, 32.20 × 10−4 ± 2.58 × 10−4 and 9.48 × 10−4 ± 1.21 × 10−4 AOD year−1, respectively. The estimated trends are statistically significant (t > 7.0) with R from 0.81 to 0.91. Seasonally, the present study also shows strong positive AOD trends at several potential sites located in the HKH2 region, such as Pokhara, Nainital, Shimla and Dehradun, with minimum 19.81 × 10−4 ± 3.38 × 10−4 to maximum 72.95 × 10−4 ± 4.89 × 10−4 AOD year−1 with statistical significance. In addition, there are also increasing AOD trends at all the high-altitude background sites in all seasons.
Blessing or Burden: Transitions Into Eldercare and Caregiver Mental Health

Caring for one’s parents can be good or bad for mental health. Guided by theories suggesting that caregiving work brings both demands and benefits, we examine if mental health outcomes depend on variations in caregiving arrangements. Using waves 5–17 from the Household Income and Labor Dynamics in Australia Survey (16,802 respondents; 115,176 person-years), we divide men and women caregivers into four groups based on their responsibility (main vs. secondary caregiver) and the location of the care recipient (inside or outside the caregiver’s household). We also examine how caregivers’ experiences are moderated by the social support they have. On average, caregivers experience no change in mental health. However, women with low social support who become main caregivers for resident parents experience declines in mental health. Men with low social support who become main caregivers for non-resident parents experience improved mental health. These results suggest that caregiver outcomes reflect different caregiving arrangements.
Intelligent Detection of Small Faults Using a Support Vector Machine

The small fault with a vertical displacement (or drop) of 2–5 m has now become an important factor affecting the production efficiency and safety of coal mines. When the 3D seismic data contain noise, it is easy to cause large errors in the prediction results of small faults. This paper proposes an intelligent small fault identification method combining variable mode decomposition (VMD) and a support vector machine (SVM). A fault forward model is established to analyze the response characteristics of different seismic attributes under the condition of random noise. The results show that VMD can effectively realize the attenuation of random noise and the seismic attributes extracted on this basis have a good correlation with the small fault. Through the analysis of the SVM algorithm and the fault forward model, it is proved that it is feasible to realize intelligent predictions of small faults by using seismic attributes as the input of a SVM. The fault prediction method using a SVM that is proposed in this paper has higher accuracy than the principal component analysis method, as the prediction results have important guiding significance and reference value for later coal mining. Therefore, the method presented in this paper can be used as a new intelligent method for small fault identification in coal fields.
Diffusive properties of colloidal charged particles in a quasi-one-dimensional confinement

Diffusive properties of colloidal crystals in a quasi-one-dimensional channel are studied using numerical simulations. In order to study the influence of the attractive interaction between particles, it was introduced as an artificial dimensionless parameter β in the attractive term of the interaction potential. Changing the value of β, we can tune the effect of attraction between particles. We show that charged particles can change their mobility and the diffusion exponent of a one-chain like system. Variation on exponent diffusion can be induced by tuning the attractive part of interaction potential, making possible the existence of diffusive regimes between single-file diffusion (SFD) and normal diffusion, without changing confinement strength. System stoichiometry was changed, imposing particles in different arrangements in small clusters, which varies the diffusive behaviour. If stoichiometry is different from 1:1, it is possible to have particles with equal charges but with different mobilities. Another important observation is that mean-square displacement (MSD) for different charges is different for different values.
A Point-Injector Applicator to Improve Fertilizer Management

Improved fertilizer management to decrease environmental losses, particularly for nitrogen, has become more important with emerging water-quality and energy-conservation concerns. Therefore, the concept of a rolling spoked-wheel, point-injector fertilizer applicator has been developed, refined, and field-tested. The applicator constructed was capable of injecting fluid fertilizer in rows of points about 10 cm (4 in.) below the soil surface with a 20 cm (8 in.) point-to-point spacing. The last design used one wheel per crop row, with an average wheel-to-wheel spacing of 76 cm (30 in.). Advantages of the system include fertilizer incorporation with low power requirements, minimum soil and residue disturbance and timing and placement options for efficient fertilizer management.
New form of composite-rotor induction motor for fan drives

A new form of composite-rotor induction motor for variable-voltage fan drives is described. The rotor incorporates a section of unlaminated steel and a conventional cage winding, and is of very simple constructional form. It is designed to achieve reduced values of maximum input current and losses, by virtue of the variation of its effective rotor impedance as a function of applied voltage. The principle of its design and operation is explained and theoretical analyses of its performance are presented. Results are given for a prototype fan drive delivering 2.25 kW output at 1400rev/min, showing stable operation and acceptable maximum losses. Computed results correlate well with those measured.
The real-time application of VSS controllers: implementation on elements of a 'direct-drive' arm, a Syke robot and a PUMA robot

The results of the application of new controllers on three robot arms is described. The initial application of variable structure control on a two link direct-drive arm is followed by its implementation on two industrial arms, a Syke robot and a PUMA arm. To allow adequate computational power in the robot controller, a separate controller was built for the first arm which was demonstrated to be portable for use on both of the industrial arms.
Diabetes in the News: Readability Analysis of Malaysian Diabetes Corpus

This paper describes a study to evaluate the readability scores of Malaysian newspaper articles meant to create awareness of diabetes among the public. In contrast to patient-specific sources of information, mass media may potentially reach healthy people, thus preventing them from becoming part of the diabetes statistics. Articles published within a selected corpus from the years 2013 to 2018 and related to awareness regarding diabetes were sampled, and their readability was scored using Flesch Kinkaid Reading Ease (FKRE). Features of three articles ranked as the best and worst for readability were qualitatively analyzed. The average readability for the materials is low at 49.6 FKRE, which may impede the uptake of information contained in the articles. Feature analysis of articles with the best and worst readability indicates that medical practitioners may not be the best spokesperson to reach the public. It also indicates that simple sentence structures could help improve readability. There is still much room for improvement in attaining good public health literacy through mass media communication. Public health and media practitioners should be vigilant of the language aspects of their writing when reaching out to the public.
Six-Week Actual Use Study to Evaluate the Impact of Oral Tobacco-Derived Nicotine Pouches on Cigarette Smoking and Smokeless Tobacco Product Use Behaviors

Background Oral tobacco-derived nicotine (OTDN) products are a rapidly emerging, innovative category of noncombustible tobacco products. These products are tobacco-leaf free and do not contain or generate many of the harmful and potentially harmful constituents (HPHCs) found in combustible cigarettes or smokeless tobacco (ST) products. OTDN products may therefore offer adult tobacco consumers a potentially reduced harm alternative. However, little is known about OTDN product use patterns or their ability to substitute for more harmful tobacco products.Methods We conducted an open-label, 2-phase, actual use study designed to characterize OTDN pouch product (on! ® nicotine pouches - NP) use patterns, including impact on other tobacco use behaviors among adult tobacco consumers interested in using NP. Adult current cigarette smokers (AS) and/or adult ST users (ASTU) (n = 1,147 complete) who were not planning to quit were offered free choice of a portfolio of NP (seven flavors at five nicotine levels) to use at-home, ad-libitum, for 6-weeks following an initial 5-day trial. Participants responded to daily electronic surveys that captured the amount, frequency, and topography (e.g., time in mouth, placement in mouth) of NP and other tobacco product use. Results The majority (99 to 100%) of study participants used NP throughout the 6-week period. Participants used ~5-6 pouches/day of a variety of flavors and nicotine levels. At the end of 6 weeks, a modest proportion of AS (27%) and a substantial proportion of ASTU (71%) reported no use of cigarettes or ST respectively, while reporting continued use of NPs. Additionally, 39% of AS and 14% of ASTU reduced daily consumption of cigarettes or ST products, respectively by 50-99%. Conclusions Participants found NPs acceptable with a sizeable proportion completely switching away from or substantially reducing (50-99%) their cigarette or ST consumption by week 6. Availability of a variety of flavors and nicotine levels appeared to facilitate the conversion to NP. These data suggest that, under the conditions of the study, NP can be a potential substitute for cigarettes or ST products and may offer harm reduction potential for adult smokers and smokeless tobacco users not interested in quitting.Trial Registration Note: This study is an observational study with tobacco products currently available in the marketplace for adult tobacco consumers. Since there is no intervention per se and we did not collect any biosamples this is not a “clinical study” and there is no appropriate registry for such behavioral observational studies, we do not believe that this requirement is applicable.
