Design and First Tests From Room Temperature to 200 mK of a 16-to-1 CMOS Multiplexing ASIC for High Impedance NbSi TESs

AbstractAchieving high spectral and spatial resolution of wide astrophysical objects in the X-ray band will be the main focus of the future X-ray space telescopes. We explore a new technological solution based on high impedance NbSi TES detectors ($$\sim $$ ∼ 2 M$$\Omega $$ Ω ) enabling the transfer of the pre-amplification stage to higher temperatures (4 K) and the use of a 50 mK CMOS time-division multiplexer to reduce power dissipation at 50 mK. We present the design and first tests, down to 200 mK, of this CMOS ASIC eventually able to work down to 50 mK and multiplexing 16 high impedance NbSi TES detectors to one 4 K amplifier with a total power budget under 2 $$\mu $$ μ W. In parallel of this development we fabricated 4-by-4 NbSi pixel matrices to build a complete demonstrator (comprising the detector array, presented in another paper to be published, the multiplexing ASIC and the 4 K amplification stage). We aim at a multiplexing frame time of 48 $$\mu $$ μ s leaving 3 $$\mu $$ μ s for reading-out each high impedance pixel. The multiplexing ASIC embeds parasitic capacity compensation techniques.

Effect of Mixing Time Variation and Framing Time on the Quality of Coffee Grounds-based Solid Soap

The increase in public consumption of coffee has resulted in an increase in wasted coffee grounds. Coffee grounds have good content for the skin, so they can be reused as a basic ingredient in soap-making. In the soap making process, the mixing and framing stages can affect the quality of the soap. This study aims to determine the effect of mixing time of 24.5 minutes, 25 minutes, and 25.5 minutes as well as framing time of 3 days, 5 days, and 7 days on the physical and chemical quality of solid soap made from coffee grounds. The physical quality parameters observed are colour, texture, cracking, and foam power. The chemical quality parameters are foam stability, pH, moisture content, and free alkali. The method used was the questionnaire method followed by statistical analysis using the Kruskal Wallis test for physical quality tests and the experimental method followed by statistical analysis using the Two-Way ANOVA test for chemical quality tests. The results showed that all variations in mixing time and framing time had an effect on the physical and chemical quality of solid soap and there were significant differences. The panellists assessed the physical quality of the soap to be attractive, hard, with no cracks, and foamy, while the results of the chemical quality test, the soap produced is safe to use by the quality standards of solid soap with a foam stability range of 82%-97%, pH 10.3-11.8, moisture content 6%-14%, and alkali free 0.03%-0.09%.

The impact of parkrun on life satisfaction and its cost-effectiveness: A six-month study of parkrunners in the United Kingdom.

An intervention suggested by the World Health Organisation that might increase life satisfaction is parkrun, a free, weekly, timed five kilometre run or walk. The issues with such interventions are (1) whether they impact on the life satisfaction of their participants, and (2) whether they are cost-effective. A study of 548 newly registered parkrunners were asked about their life satisfaction at baseline and six months later. A change of one life satisfaction point per year per participant was defined as one WELLBY (wellbeing adjusted life year), with a value of £13,000. Three approaches were used to estimate the additionality (added value) of parkrun: (1) by comparing a participant's number of parkruns to total activity; (2) by accounting for the participant's perceived impact of parkrun across 16 measures; and (3) combining these two methods equally. After six months, weighted, seasonally adjusted life satisfaction increased from a mean of 7.489 to 7.746, a change of 0.257. Both life satisfaction improvement and additionality were greatest for the least active. Assuming only half a year of benefit, the total value of the life satisfaction change for the 2019 parkrun population of 400,167 participants was estimated as £667.4m, with the least active accounting for almost half. Comparing to the cost of running parkrun in 2019 and using the activity, impact and combined methods for additionality, benefit-cost analysis ratios were found to be 16.7, 98.5 and 59.3 to 1, respectively. These were between 2.8 to 16.7 times that of other population-level physical activity interventions. Physical health was a mediator between activity and life satisfaction; mental health was only found as a mediator when combined with physical activity. Successful features of parkrun that might guide other interventions include its framing (role, time, place and cost) and ability to forge both strong and weak social ties.

Miniscope Recording Calcium Signals at Hippocampus of Mice Navigating an Odor Plume.

Mice navigate an odor plume with a complex spatiotemporal structure in the dark to find the source of odorants. This article describes a protocol to monitor behavior and record Ca2+ transients in dorsal CA1 stratum pyramidale neurons in the hippocampus (dCA1) in mice navigating an odor plume in a 50 cm x 50 cm x 25 cm odor arena. An epifluorescence miniscope focused through a gradient-index (GRIN) lens imaged Ca2+ transients in dCA1 neurons expressing the calcium sensor GCaMP6f in Thy1-GCaMP6f mice. The paper describes the behavioral protocol to train the mice to perform this odor plume navigation task in an automated odor arena. The methods include a step-by-step procedure for the surgery for GRIN lens implantation and baseplate placement for imaging GCaMP6f in CA1. The article provides information on real-time tracking of the mouse position to automate the start of the trials and delivery of a water reward. In addition, the protocol includes information on using an interface board to synchronize metadata describing the automation of the odor navigation task and frame times for the miniscope and a digital camera tracking mouse position. Moreover, the methods delineate the pipeline used to process GCaMP6f fluorescence movies by motion correction using the NorMCorre algorithm followed by identification of regions of interest with EXTRACT. Finally, the paper describes an artificial neural network approach to decode spatial paths from CA1 neural ensemble activity to predict mouse navigation of the odor plume.

Performance of the SOAR Speckle Instrument

The High Resolution Camera (HRCam) speckle imager at the 4.1 m Southern Astrophysical Research telescope is a highly productive instrument that has accumulated about 40K observations to date. Its performance (detected flux, level of the speckle signal, signal-to-noise ratio, and limiting magnitude) is studied here using both the actual data and realistic simulations, including the detector noise. In the calculation of the speckle power spectrum, signal clipping is essential to reduce the noise impact and maximize the sensitivity. Increasing exposure time of individual frames beyond 30 ms does not improve the limiting magnitude, which ranges from 11.5 to 14 mag under a seeing from 1.″6 to 0.″6 in the wide-band I filter. A gain of at least one magnitude is expected if the current electron multiplication CCD is replaced by a high-end CMOS detector with a subelectron readout noise. This study will help in planning, executing, and automating future speckle observations with HRCam and other speckle imagers.

The effect of material properties and process parameters on die filling at varying throughputs: A PLS-model-based analysis

When tablets are manufactured on a rotary tablet press and the throughput is increased, it leads to changes in powder dynamics during die filling due to formulation characteristics and changing powder flow in the feed frame. This may result, a.o. in increased tablet weight variability, poorer content uniformity, capping and lamination. This research focuses on explaining the die filling performance depending on material properties and process settings, including throughput for small and large tablets. It was concluded that throughput had a negative impact on die filling variability, which is related to reduced residence time and lower fill fraction of the feed frame and dies. Furthermore, the die filling mechanism was inherently different for large tablets in comparison to small tablets. Higher die filling consistency was observed for dense, less porous, less compressible and better flowing powders. As a result of this work, a model was developed to predict the impact of formulation properties and process settings on die filling variability and its dependency on changes in throughput. This model will benefit formulation development at an early stage when active ingredient availability may be challenging as it will avoid the need to conduct experiments at high throughputs.

Comparative analysis of computer vision algorithms for the real-time detection of digital dermatitis in dairy cows

Digital dermatitis (DD) is a bovine claw disease responsible for ulcerative lesions on the planar aspect of the hoof. DD is associated with massive herd outbreaks of lameness and influences cattle welfare and production. Early detection of DD can lead to prompt treatment and decrease lameness. Computer vision (CV) provides a unique opportunity to improve early detection. The study aims to train and compare applications for the real-time detection of DD in dairy cows. Eight CV models were trained for detection and scoring, compared using performance metrics and inference time, and the best model was automated for real-time detection using images and video. Images were collected from commercial dairy farms while facing the interdigital space on the plantar surface of the foot. Images were scored for M-stages of DD by a trained investigator using the M-stage DD classification system with distinct labels for hyperkeratosis (H) and proliferations (P). Two sets of images were compiled: the first dataset (Dataset 1) containing 1,177 M0/M4H and 1,050 M2/M2P images and the second dataset (Dataset 2) containing 240 M0, 17 M2, 51 M2P, 114 M4H, and 108 M4P images. Models were trained to detect and score DD lesions and compared for precision, recall, and mean average precision (mAP) in addition to inference time in frame per second (FPS). Seven of the nine CV models performed well compared to the ground truth of labeled images using Dataset 1. The six models, Faster R-CNN, Cascade R-CNN, YOLOv3, Tiny YOLOv3, YOLOv4, Tiny YOLOv4, and YOLOv5s achieved an mAP between 0.964 and 0.998, whereas the other two models, SSD and SSD Lite, yielded an mAP of 0.371 and 0.387 respectively. Overall, YOLOv4, Tiny YOLOv4, and YOLOv5s outperformed all other models with almost perfect precision, perfect recall, and a higher mAP. Tiny YOLOv4 outperformed all other models with respect to inference time at 333 FPS, followed by YOLOv5s at 133 FPS and YOLOv4 at 65 FPS. YOLOv4 and Tiny YOLOv4 performed better than YOLOv5s compared to the ground truth using Dataset 2. YOLOv4 and Tiny YOLOv4 yielded a similar mAP of 0.896 and 0.895, respectively. However, Tiny YOLOv4 achieved both higher precision and recall compared to YOLOv4. Finally, Tiny YOLOv4 was able to detect DD lesions on a commercial dairy farm with high performance and speed. The proposed CV tool can be used for early detection and prompt treatment of DD in dairy cows. This result is a step towards applying CV algorithms to veterinary medicine and implementing real-time DD detection on dairy farms.

Underwater Multi-Channel MAC with Cognitive Acoustics for Distributed Underwater Acoustic Networks.

The advancement of underwater cognitive acoustic network (UCAN) technology aims to improve spectral efficiency and ensure coexistence with the underwater ecosystem. As the demand for short-term underwater applications operated under distributed topologies, like autonomous underwater vehicle cluster operations, continues to grow, this paper presents Underwater Multi-channel Medium Access Control with Cognitive Acoustics (UMMAC-CA) as a suitable channel access protocol for distributed UCANs. UMMAC-CA operates on a per-frame basis, similar to the Multi-channel Medium Access Control with Cognitive Radios (MMAC-CR) designed for distributed cognitive radio networks, but with notable differences. It employs a pre-determined data transmission matrix to allow all nodes to access the channel without contention, thus reducing the channel access overhead. In addition, to mitigate the communication failures caused by randomly occurring interferers, UMMAC-CA allocates at least 50% of frame time for interferer sensing. This is possible because of the fixed data transmission scheduling, which allows other nodes to sense for interferers simultaneously while a specific node is transmitting data. Simulation results demonstrate that UMMAC-CA outperforms MMAC-CR across various metrics, including those of the sensing time rate, controlling time rate, and throughput. In addition, except for in the case where the data transmission time coefficient equals 1, the message overhead performance of UMMAC-CA is also superior to that of MMAC-CR. These results underscore the suitability of UMMAC-CA for use in challenging underwater applications requiring multi-channel cognitive communication within a distributed network architecture.

Sabun Homemade Dengan Ekstrak Vitis Vinifera Menggunakan Framming Time

Natural soap is one of the products that do not use chemicals that people need to clean the body and maintain healthy skin. Vitis vinifera and olive oil contain antioxidants and antimicrobials that are useful for brightening and moisturizing skin, increasing skin cell turnover, and making skin healthier. This research aims to obtain natural soap made from olive oil with the addition of grape extract (Vitis vinifera). The research method includes the process of making grape extract soap with varying framing times (3, 5, and 7 days), then the grape soap is stored for 4 weeks followed by analysis of pH levels, crack tests, and organoleptic tests including texture, color strength and foam. The final pH test results were in the range of 9.0-11.0 which were checked in the first seven days. This soap has texture ranges from 2.50 (slightly soft) to 3.84 (hard), soap color ranges from 3.15 (slightly interesting) to 4.00 (interesting), and foaming power ranges from 3.00 (slightly foamy) to 3.50 (foamy).

THE BIGGER, THE BETTER? TWO-RING CIRCULAR FRAMES AND DURATION OF TREATMENT IN THE MANAGEMENT OF TIBIAL FRACTURES: A RETROSPECTIVE COHORT STUDY

IntroductionFrame configuration for the management of complex tibial fractures is highly variable and is dependent not only on fracture pattern and soft tissue condition but also surgeon preference. The optimal number of rings to use when designing a frame remains uncertain. Traditionally, larger, stiffer constructs with multiple rings per segment were thought to offer optimal conditions for bone healing, however, the concept of reverse dynamisation questions this approach.Materials & MethodsWe compared clinical outcomes in 302 consecutive patients with tibial fractures treated in our unit with either a two-ring circular frame or a three-or-more-ring (3+) frame. The primary outcome measure was time spent in frame. Secondary outcomes were the incidence of malunion and the need for further surgical procedures to achieve bone union. The groups were evenly matched for age, co-morbidities, energy of injury mechanism, fracture classification, post-treatment alignment and presence of an open fracture.ResultsThe mean time in frame was 168 days for the 2-ring group and 200 days for the 3+ rings group (p=0.003). No significant difference was found in the rate of malunion (p=0.428) or the requirement for secondary surgical intervention to achieve union (p=0.363). No significant difference in time in frame was found between individual surgeons.ConclusionsThis study finds that 2-ring frame constructs are a reliable option associated with significantly shorter duration of treatment and no increase in rates of adverse outcomes compared with larger, more complex frame configurations. Although this study cannot identify the underlying cause of the difference in treatment time between frame designs, it is possible that differences in mechanical stability lead to a more favourable strain environment for fracture healing in the 2-ring group.

CIRCULAR FRAME IN THE PRESENCE OF PRE-EXISTING ARTHROPLASTY: IS THERE AN UNACCEPTABLE RISK OF INFECTION?

IntroductionCircular external frames (CEF) are commonly used for a wide variety of indications, often when other devices are not appropriate. Circular frames are particularly associated with pin-site infection (PSI). Currently there is a gap in the available literature surrounding the risk of frame use with in-situ prosthetic joints. This retrospective study investigated the incidence of prosthetic joint infection (PJI) in a series of patients with in-situ arthroplasties treated with CEF.Materials & MethodsFrom a departmental database of 1052 frames performed from March 2007-March 2023, the outcomes of 34 patients (40 frames) with in-situ arthroplasties at the time of CEF were reviewed (mean follow-up 70 months). Patient identification was by review of all local and regional imaging. The primary outcome was development of PJI during or following CEF and subsequent need for surgical intervention. Secondary outcomes were development of superficial pin site or deep bone infection (without PJI).ResultsOf 40 frames used to treat 34 patients, no PJIs were detected. Average patient age was 67 (range 55–82). 22 had cardio-respiratory disease, 11 diabetes, 15 smoked and 8 were immunosuppressed. 53 arthroplasties were in situ at the time of treatment, 12 involving the same bone as the frame. Average time in frame was 253 days. 23 patients developed PSI, 2 required a further procedure for persistent deep bone infection not involving the arthroplasties.ConclusionsAlthough this study involves a relatively low numbers of patients, our results are reassuring that circular frame management in patients with in-situ arthroplasty does not represent an unacceptable risk of PJI. We hope to promote these findings and encourage multi-centre collaboration to expand on the available evidence to better answer this important yet under-reported clinical question.

SELECTIVE REMOVAL OF ILIZAROV FRAMES WITHOUT A PERIOD OF DYNAMIZATION APPEARS SAFE

IntroductionTraditionally, radiological union of fractures treated with an Ilizarov frame is confirmed by a period of dynamization - destabilisation of the frame for a period prior to removal. Reduced clinic availability during the COVID-19 pandemic caused a shift to selective dynamisation in our department, whereby lower risk patients had their frames removed on the same day as destabilisation. This study investigates the effects of this change in practice on outcomes and complication rates.Materials & MethodsAdult patients treated with circular frames between April 2020 and February 2022 were identified from our Ilizarov database. Patients were divided into 2 groups: - “dynamised” if their frame was destabilised for a period to confirm union prior to removal; or “not dynamised” if the decision was taken to remove the frame without a period of dynamisation, other than a short period in the clinic. A retrospective review of clinical notes was conducted to determine outcome.Results175 patients were included in the final analysis, 70 in the dynamised and 103 in the not dynamised groups, median follow-up was 33 months. 3 patients in the dynamised group failed dynamisation and had their period of fixation extended, subsequently having their frames removed without complication. Two patients suffered a refracture or non-union after frame removal in the dynamised group and none in the not dynamised group, this difference was not statistically significant.ConclusionsIn our practice, selective frame removal without a period of dynamisation appears safe. This has the potential to shorten frame time and reduce the number of clinic appointments and radiographic investigations for these patients. Some patients find the period of dynamisation uncomfortable and associated with pin site infection, which can be avoided. We plan to continue this practice and collect further data to confirm these findings in a larger dataset.

THE RESULTS OF TWO-RING HEXAPODS IN THE LOWER LIMB AT KING'S COLLEGE HOSPITAL

IntroductionClassical fixation using a circular frame involves two rings per segment and in many units this remains the norm whether using ilizarov or hexapod type frames. We present the results of two ring circular frame at King's College Hospital.Materials & MethodsA prospective database has been maintained of all frames applied since 2007. Radiographs from frames applied prior to July 2022 were examined. Clinic letters were then used to identify complications.Included: two ring hexapod for fracture, malunion, nonunion, arthrodesis or deformity correction in the lower limb.Excluded: patients under 16 years old, diabetic feet, Charcot joints, soft tissue contractures, arthrodiastasis, correction of the mid/forefoot, plate fixation augmentation, fixation off a third ring.Results518 two ring hexapods were identified. Mean age was 46 (16–89). 55% were for fracture, 18% for malunion, 11% for nonunion. Mean frame time was 7 months (2–29 months).All clinic letters from 384 patients showed 203 patients (52%) had at least one pin site infection, 27 nonunions (7%), 16 frame revisions (4%), 25 bone grafting procedures (7%), 5 cases of septic arthritis (1%), 3 periprosthetic fractures (0.8%),), 12 malunions (3%), 4 Amputations (1%).ConclusionsThese results demonstrate the efficacy of a two ring hexapod for patients requiring reconstruction of the lower limb.

When time drives search effort: the effect of assortment variety on visual attention to SKU pricing

PurposeUnderstanding the effect of assortment composition on attentional levels is an essential topic for academic researchers and practitioners. This work has important implications when analyzing the influence of shopping frame time and search effort on the relationship between the reaction to assortment composition and visual attention to stock-keeping units (SKUs) pricing.Design/methodology/approachTwo experimental studies through gauze behavior analysis technology (using eye-tracking equipment) analyze the variable's large assortment, visual attention to SKU pricing, search effort and shopping frame time.FindingsThe results suggest that, although it increases the search effort, a large assortment decreases the visual attention to SKU pricing. Further, our results indicate a moderating effect associated with mitigating the negative effect by medium-low levels of search effort and a moderating impact of time in this relation.Practical implicationsMarketing professionals can carefully optimize the in-store experience by managing the assortment and variety and by influencing consumers' visual attention to SKU pricing along the journey as part of the experience. Assortment and SKU pricing strategies need to be aligned with consumer journey design.Originality/valueOur findings contribute to assortment theory and management by detailing the relationship between consumers' reactions to assortment perception and visual attention to SKU pricing in time flow. We reinforce the importance of considering assortment strategies from the consumer perspective and giving reliable information about in-store behavior.

Metatarsal lengthening by distraction osteogenesis for brachymetatarsia in paediatric patients: is it safe and effective?

The primary aim is to assess the efficacy of the surgical callus distraction technique of the metatarsus in paediatric patients. Secondary objectives are to assess complications and treatment duration. We have also described the details of our surgical technique. A case series review of paediatric patients who had metatarsal lengthening at our unit between 2014 and 2022. Patient demographics, duration of time in frame, complications and metatarsal length achieved were recorded. The AOFAS Midfoot and the MOXFQ were taken pre-operatively and at final follow-up. Sixteen metatarsals in 8 patients (14 feet) underwent lengthening between 2014 and 2022 using the MiniRail OrthoFix 100 (Orthofix Medical Inc, Lewisville, TX, USA). The mean age was 13.3 (12-17) years. The average duration between surgery and implant removal was 5.2months. According to Paley's classification, there was one obstacle encountered in a patient who required a revision of their osteotomy and one problem in another patient who had an infected metatarsophalangeal joint stabilising k-wire treated with oral antibiotics. The Mean AOFAS Midfoot score improved from 53.10 to 86.40 (p < 0.0001) and the Mean MOXFQ improved from 32.5000 to 12.1250 (p < 0.05); these were statistically significant. Gradual metatarsal lengthening using the MiniRail external fixator is a safe and effective method to treat brachymetatarsia in paediatric patients. This preliminary report describes and supports metatarsal lengthening in appropriate patients. Holistic care in terms of a pre-operative assessment, psychological support and preparation for the extended rehabilitation period are vital.

Improving efficiency of DNN-based relocalization module for autonomous driving with server-side computing

The substantial computational demands associated with Deep Neural Network (DNN)-based camera relocalization during the reasoning process impede their integration into autonomous vehicles. Cost and energy efficiency considerations may dissuade automotive manufacturers from employing high-computing equipment, limiting the adoption of advanced models. In response to this challenge, we present an innovative edge cloud collaborative framework designed for camera relocalization in autonomous vehicles. Specifically, we strategically offload certain modules of the neural network to the server and evaluate the inference time of data frames under different network segmentation schemes to guide our offloading decisions. Our findings highlight the vital role of server-side offloading in DNN-based camera relocation for autonomous vehicles, and we also discuss the results of data fusion. Finally, we validate the effectiveness of our proposed framework through experimental evaluation.

Incidental carcinoma of the prostate in cystoprostatectomy specimens - is it always a toothless lion?

Incidental prostate carcinoma (iPC) is a subject of debate concerning its definition, incidence, biology, diagnosis, staging, and treatment. The present study aimed to assess the incidence and main clinical-morphological characteristics of iPC identified in radical cystoprostatectomy (RCP) specimens over a 5-year period. Using the database of the Urology and Pathology Departments, we identified all patients with bladder carcinomas (BCs) who underwent RCP within a 5-year frame time. We selected only those patients with synchronous BC and prostate carcinoma (PC). The following parameters were analyzed for these patients: age, type of bladder and prostate tumor, degree of differentiation, pathological stage, and other prognostic parameters. We identified 91 men with bladder tumors treated by RCP among whom 43, aged between 53 and 84 years (mean age: 69.2 years), presented synchronous PC. iPC was more prevalent in older individuals (>65 years: 30 patients, 69.8%), with only six out of the 43 (12.8%) patients with iPC being aged ≤60 years. All iPC cases were conventional adenocarcinoma. Well-differentiated prostate adenocarcinomas (grade group 1) predominated (65.1%). Among the 43 iPCs, 16 (37.2%) were clinically significant PCs. iPC is frequently identified in patients with BC when inclusion and evaluation of all or most of the prostate tissue are performed. Although more than half of iPCs were well-differentiated tumors confined to the prostate, a significant number of cases met the criteria of clinically significant PC. All men over the age of 50 who are candidates for RCP, should undergo evaluation through serum prostate specific antigen determination.

Wave beams, packets and pulses in inhomogeneous non-Hermitian media with dispersive gain or damping

Wave beams, packets or pulses are known to be subject to a drift if the properties of the medium change across their extension. This effect is often analyzed considering the dispersive properties of the oscillation, related to the real part of the dispersion relation. The evolution of Gaussian beams/packets/pulses in nonuniform media in the presence of gain or damping is investigated in detail, with particular emphasis on the role of dispersion on both the real and the imaginary part of the dispersion relation. In the paraxial limit, the influence of a non-Hermitian medium on the evolution of the wave can be treated employing the equations derived by Graefe and Schubert in the frame of non-Hermitian quantum mechanics (Phys. Rev. A 83 060101(R)). Analytic solutions of the corresponding paraxial equations are obtained here for a one-dimensional complex dispersion relation characterized by a linear or quadratic dependence on the transverse coordinate (a space coordinate for beams and packets, the time in the co-moving frame for a pulse). In the presence of a constant gradient in both the real and the imaginary part of the dispersion relation, the contribution of the latter can lead to a faster or slower propagation with respect to the Hermitian case, depending on the parameters. In focusing media, a constant gain can counteract dispersive or inhomogeneous damping producing packets of asymptotically constant shape. The analytic formulas derived in this paper offer a way to predict or control the properties of beams/packets/pulses depending on their initial conditions and on the characteristics of the medium.

The effect of systematic and unsystematic determinants on loan (financing) to deposit ratio in Indonesian banking

Purpose: This study compares the determinants of liquidity of Islamic Banks (IBs) and Conventional Banks (CBs) based on the loan-to-deposit ratio (LDR) and financing-to-deposit ratio (FDR) between 2016 and 2020. Research Methodology: The data analysis technique used was panel data regression. Results: The results show Economic growth has a positive effect on banking liquidity risk, while non-performing loans (financing) have a negative effect on banking liquidity risk. Limitations: The frame time in this research was 2016-2020 which, before Bank Syariah Mandiri, Bank Rakyat Indonesia (BRI) Syariah, and Bank Negara Indonesia (BNI) Syariah merged into Bank Syariah Indonesia. Contribution: This study can be used as a reference for preparing or perfecting regulations that can be bolder in expanding credit (financing). Commercial banks are expected to be able to manage liquidity so that the liquidity ratio is not less than or exceeds the tolerance limit, especially for CBs, and are used as evaluation material for the performance of IBs, especially CBs. Novelty: Several previous studies conducted separate analyses of the determinants of LDR and FDR in one type of commercial bank and showed contradictory results. This research did not conduct separate analyses in one type of bank but combined the determinants so that they could cause liquidity risk by measuring LDR on BUK and FDR on BUS to discuss these conflicting findings.

3D human pose estimation with single image and inertial measurement unit (IMU) sequence

Three-dimensional human pose estimation plays an important role in the field of computer vision, such as in healthcare, sports, activity recognition, motion capture, and augmented reality. However, monocular image or video based methods are sensitive to occlusions, while multi-view methods usually require enormous computation resources. Currently, inertial measurement unit (IMU)-based methods have begun to overcome the occlusion problem and can potentially achieve real-time inference. Yet, they still suffer from insufficient precision and scale drift error over time. In this paper, we propose a novel, efficient framework to fuse a single image with temporal sequence from IMU sensors to estimate human poses and reconstruct human shapes. Our method achieves 46 mm Mean Per Joint Positional Error (MPJPE) on the Total Capture dataset with 30 frames time segment, and surpasses state-of-the-art pure IMU-based methods. Moreover, in comparison with other vision-based methods, the proposed method shows great advantage in reducing computing floating point operations per second (FLOPS) quota while still achieving competitive estimation precision. Our method achieves 74 FPS on an IPhone 12 for offline processing. In addition, our method can easily be generalized for outdoor cases.
