Inspecting End-to-End Encrypted Communication Differentially for the Efficient Identification of Harmful Media

Due to the immense benefits of guaranteeing user privacy, popular messaging platforms have shown enthusiasm for deploying End-to-End Encryption (E2EE). However, E2EE could be misused for bypassing media moderation, opening a shortcut for the viral spreading of harmful media. Private hash-matching techniques are proposed to identify harmful content in E2EE. Unfortunately, the pioneering solution incurs prohibitively high latency due to redundant user-cloud interactions for a private inspection. In this paper, we design Entbergen for efficient inspection of E2EE media by differentially handling harmless and harmful ingredients. For this, a novel Private-2D BloOm filter with Fuzzy Query (PBO-FQ) is designed for local, agile, and private media hash matching. It is proposed as the first structure that adapts inverted index and differential privacy (DP) towards seamless integration of sketch and mask encoding. With PBO-FQ, Entbergen can instantly filter out harmless media and only pays attention to the small-scale counterparts by scrutinizing them privately based on homomorphic encryption. Security analysis shows that Entbergen can effectively fulfil the desired privacy requirements. Extensive evaluations demonstrate that Entbergen is sufficiently efficient (w.r.t. computation and communication overhead) for working on mobile devices and can easily scale to real-world inspection with a large database.
The gut microbiota from maintenance hemodialysis patients with sarcopenia influences muscle function in mice

Background Sarcopenia is a common complication in patients undergoing maintenance hemodialysis (MHD). Growing evidence suggests a close relationship between the gut microbiota and skeletal muscle. However, research on gut microbiota in patients with sarcopenia undergoing MHD (MS) remains scarce. To bridge this knowledge gap, we aimed to evaluate the pathogenic influence of gut microbiota in the skeletal muscle of patients with MS, to clarify the causal association between gut microbiota and skeletal muscle symptoms in patients with MS and identify the potential mechanisms underlying this causal association. Methods Fecal samples were collected from 10 patients with MS and 10 patients without MS (MNS). Bacteria were extracted from these samples for transplantation. Mice (n=42) were randomly divided into three groups and, after antibiotic treatment, fecal microbiota transplantation (FMT) was performed once a day for 3 weeks. Skeletal muscle and fecal samples from the mice were collected for 16S rRNA gene sequencing and for histological, real-time PCR, and metabolomic analyses. Results Mice colonized with gut microbiota from MS patients exhibited notable decreases in muscle function and muscle mass, compared with FMT from patients with MNS. Moreover, 16S rRNA sequencing revealed that the colonization of MS gut microbiota reduced the abundance of Akkermansia in the mouse intestines. Metabolome analysis revealed that seven metabolic pathways were notably disrupted in mice transplanted with MS microbiota. Conclusion This study established a connection between skeletal muscle and the gut microbiota of patients with MS, implying that disruption of the gut microbiota may be a driving factor in the development of skeletal muscle disorders in patients undergoing MHD. This finding lays the foundation for understanding the pathogenesis and potential treatment methods for sarcopenia in patients undergoing MHD.
Rapid fluid flow along fractures at greenschist facies conditions on Syros, Greece

Brittle fractures cut through greenschist facies metavolcanic rocks at Delfini on Syros, Greece. An equation for one-dimensional transport by advection along a single fracture and transverse diffusion outwards from this fracture was used to calculate time-averaged fluid velocities and the duration of fluid flow along the brittle fractures. These quartz and carbonate filled fractures are surrounded by symmetrical dark reaction halos. These reaction halos were formed by diffusion of CO2 outwards from the fracture in a hydrous fluid which caused carbonation of the country rock. Changes in concentration of relatively mobile elements (for example K, Na, Cs, Ba, Pb and Sr) occurred. However, little to no changes in most of the major elements and less mobile trace elements were observed. This implies that carbonation was largely isochemical with respect to most non-volatile components. The Sr/Ca ratio was used to model time-averaged fluid velocities and the duration of fluid flow along the fractures. Fluid flow along narrower fractures with discernibly tapering haloes was found to be rapid (10−6 – 10−5 ms−1) and short lived (0.1–400 years). These are time-averaged values and can therefore alternatively record a series of even shorter and faster pulses, perhaps associated with fracture propagation and associated seismicity. Within the widest fractures with constant halo widths (ca. 60 cm) fluid flow was slower (10−8 to 10−6 ms−1) and longer lived (100–15000 years). We suspect that the constant width of these haloes reflects a steady state having been reached at which halo width was controlled by the relative rates of fluid flow along the fracture and in the surrounding rock.
An analysis of intrauterine foetal demise in a tertiary care hospital

Background: Intrauterine foetal demise or still birth refers to an antepartum or intrapartum foetal death occurring after 20 weeks of gestation. The majority of these deaths would probably be prevented with better access to expert healthcare and providing health education to the women. Aims: To find out the associated risk factors for antepartum intra uterine foetal demise and determine the probable cause of antepartum foetal demise Materials& methods: This is a prospective study conducted at R.L JALAPPA Hospital attached to Sri Devaraj Urs Medical College, Tamaka, Kolar included all antepartum intrauterine foetal demises after 24 weeks of gestation between January 2021 to December 2022. Results: In the present study, the maternal causes of intrauterine foetal demise, hypertensive disorders contributed to 46.65% followed by anaemia. Amongst the foetal factors, foetal growth restriction seen in 26.6%. Statistically significant difference was found between birth weight and gestational age, attributing to the foetal growth restriction. In placental causes abruption placenta accounted for 15.23% and idiopathic constituted 26.7%. Decreased perception of foetal movements was seen in majority of the cases. Conclusion: Finding the causes of IUFD will enable the development of a successful prevention strategy, preventing maternal problems in the process. Good antenatal care and detection of risk factors like preeclampsia, anaemia, FGR, congenital malformations are necessary to plan the next level of management. Not only that a potential life is lost, mothers experiencing intrauterine foetal demises suffer psycho-social consequences like anxiety, depression, stress disorders and stigmatization and also the future prospects of fertility and pregnancy outcome becomes one the major concerns for them, DC.
Hydromechanics – Slope Monitoring in Rainy Season

Rainfall and soil response are necessary to be monitored to have slope characteristics in detecting landslide occurrence. Even though much research has been carried out worldwide for rainfall monitoring, less research has been conducted in Indonesia for slope monitoring. Therefore, this research was conducted to observe the suction, soil moisture content, and rainfall in a silty sand slope. An automatic rain gauge was set on the ground to measure precipitation. Tensiometer and soil moisture content sensors were installed at depths of 0.5 m; 1 m; and 1.5 m from the slope surface. The monitoring was conducted during the peak rainy season from December 2022 to January 2023. The rainfall amount is about 436.6 mm, and the 6 hours of rainfall events contribute a relatively sizeable rainfall amount (about 31%) to the total. The safety factor of the slope is estimated to decrease by 39%-40% due to the rainfall.
Vision-Based 3D Motion Estimation for On-Orbit Proximity Satellite Tracking and Navigation

Abstract : The main challenge addressed in this work is to develop and validate an algorithm able to track and estimate the relative position and motion of on-orbit, un-modeled targets by using only passive vision. The algorithm developed is based on well-known image processing techniques. To achieve this goal, a number of different approaches were analyzed and compared to assess their performance for a satisfactory design. The code also has a modular general structure in order to be more flexible to changes during the implementation until best performance is reached. Artificially rendered high quality, animated videos of satellites in space and real footage provided by NASA have been used as a benchmark for the calibration and test of the main algorithm modules. The final purpose of this work is the validation of the algorithm through a hardware-in-the-loop ground experiment campaign. The development of the Floating Spacecraft Simulation Test-bed used in this work for the validation of the algorithm on real-time acquisition images was also documented in this thesis. The test-bed provides space-like illumination, stereovision and simulated weightlessness frictionless conditions. Insight on the validity of this approach, describing the performance demonstrated by the experiments, the limits of the algorithm and the main advantages and challenges related to possible future implementations in space applications, were provided by this research.
Development of Selection Model of Subway Station Influence Area (SIA) in Seoul City using Chi-square Automatic Interaction Detection (CHAID)

In general, based on criteria of subway law, radius 500m from subway station is defined as SIA (Subway Station Influence Area). Therefore, in this paper, selection models of SIA are developed to identify appropriate SIA for specific legions in Seoul metropolitan city based on CHAID analysis. As a result, following outputs are obtained; (1) walking distance from subway station is the most influential factor to define SIA (2) SIAs vary with regions (i. e. Gangnam area: 767m, Gangbuk area: 452m), and (3) walking distance from subway station is influential to land price of SIA. In addition, in Gangnam, the structure of land price of the closest section has a polynomial trend curve rather than linear compared in comparison with other sections. Therefore, it is desirable for current definition of SIA (radius 500m from subway station) to be redefined to reflect characteristics of land use and walking distance according to each region respectively.
The Geologic and Archaeological History of the Dickie Carr Site 41PR26

This thesis is an analysis and synthesis of the geologic and archaeological history of the Dickie Carr site, 41PR26, on Mill Creek in north central Texas. Included are analyses of the stratigraphy, sedimentary environments, and soils of the locality. A regional comparison is made with respect to the Late Quaternary geology of the upper Trinity River basin, Texas to interpret the geologic data. Two stratigraphic units were identified that record the Pleistocene-Holocene transition. The buried lower unit is comprised of terrace, floodplain, and channel deposits with extensive pedogenesis. The unit is Late Pleistocene in age and contains the remains of Mammuthus columbi. The upper stratigraphic unit is comprised of terrace and floodplain sediments with well-expressed pedogenesis. The unit is Early Holocene in age with Late Paleoindian and Late Archaic occupations. The archaeological components are compared and contrasted with documented sites from the Elm and East Forks of the Trinity River. The occupations are examined in a geoarchaeological context. The Late Paleoindian occupation is post-depositional and located in terrace deposits. The Late Archaic occupation is syndepositional and located in floodplain deposits.

Convergence theorems for adapted sequences of random sets

Abstract We consider random sets with values in a separable Banach space. We study set-valued amarts, L1-amarts, uniform amarts and submartingales. For all these classes of random sets, we prove convergence theorems in all main modes of set convergence (weak, Wijsman, Mosco, and Hausdorff). We also prove new convergence theorems for vector-valued subpramarts and pramarts.
Association of Aquaporin 7 and 9 with Obesity and Fatty Liver in db/db Mice

Aquaporin (AQP) 7 and AQP9 are membrane channel proteins called aquaglyceroporins and are related to glucose and lipid metabolism. AQP7 is mainly expressed in white adipose tissue (WAT) and is involved in releasing glycerol into the bloodstream. AQP9 is the glycerol channel in the liver that supplies glycerol to the hepatic cells. In this study, we investigated the relationship between the expression of aquaglyceroporins and lifestyle-related diseases, such as obesity and fatty liver, using 22-week-old db/db mice. Body weight, WAT, and liver weight showed increases in db/db mice. The levels of liver lipids, plasma lipids, insulin, and leptin were also increased in db/db mice. Gene expression related to fatty acid and triglyceride synthesis in the liver was enhanced in db/db mice. In addition, gene and protein expression of gluconeogenesis-related enzymes was increased. Conversely, lipolysis-related gene expression in WAT was reduced. In the db/db mice, AQP9 expression in the liver was raised; however, AQP7 expression in WAT was reduced. These results suggest that in db/db mice, enhanced hepatic AQP9 expression increased the supply of glycerol to the liver and induced fatty liver and hyperglycemia. Additionally, reduced AQP7 expression in WAT is associated with excessive lipid accumulation in adipocytes. Aquaglyceroporins are essential molecules for glucose and lipid metabolism, and may be potential target molecules for the treatment of obesity and lifestyle-related diseases.
Determinants of CEO Investment Horizon. A Literature Review

This paper conducts a comprehensive literature review of the factors influencing the emergence of the CEO investment horizon problem – a preference for short-term investments over long-term ones. The root cause of this CEO issue, as in-dicated in existing literature, is often attributed to the CEO's personal risk attitude, shaped by factors like age, tenure, and cultural background.Numerous sources contributing to the short-term investment problem in public companies are described in the current academic literature. Prominent among these determinants are the challenges of quarterly reporting, the association of corporate performance with short-term metrics, market pressures, and the company's specific risk profile. A study by McKinsey & Company, focused on the short horizon problem, demonstrates that companies inclined toward short-term investments exhibit weaker fundamentals and performance. The consulting firm Ernst & Young has introduced the Long-term Orientation Index, offering a basis for cross-country comparison of decision horizons. In 2010, Antia and colleagues introduced a metric for measuring CEO decision horizons, which relies on CEO personal characteristics. Despite these efforts, a comprehensive literature review addressing the specificity of the CEO investment horizon problem and its dis-tinctions from the broader corporate investment horizon problem has been absent.This paper not only investigates the initial empirical exploration of the short investment horizon problem but also raises questions about its cross-country manifestations, its potential correlation with economic crises, and the relevant personal traits of CEOs for its study. Finally, the paper proposes various strategies to mitigate the CEO investment horizon problem within companies.
A Rail-to-Rail 12 MS/s 91.3 dB SNDR 94.1 dB DR Two-Step SAR ADC With Integrated Input Buffer Using Predictive Level-Shifting

Input buffers can be used to reduce the input load of high-resolution discrete-time (DT) Nyquist analog-to-digital converters (ADCs), which can be challenging to drive, particularly at high sampling rates, because of the large input sampling capacitance needed to reduce thermal noise. An input driving technique called predictive level-shifting is proposed to drive rail-to-rail signal swing without increasing the buffer supply rail for high linearity. This article demonstrates an easy-to-drive two-step successive approximation register (SAR) ADC with integrated input buffer, achieving 91.3 dB peak signal-to-noise-and-distortion ratio (SNDR) and 94.1 dB dynamic range (DR) with 6.6 V peak-to-peak differential signal swing and 4 MHz input frequency at 12 MS/s with 30.41 mW power consumption, demonstrating the best performance among the published literature.
SETTLEMENTS IN SOFT CLAY AROUND A PUMPED EXCAVATION IN OSLO

The paper first gives an account of the observed and calculated settlements of old apartment houses occupying an area, typical for Oslo, where soil conditions vary rapidly from outcropping rock to deep soft clay. The disturbance to these buildings caused by the construction of a deep basement in the area, for an extension to Oslo Technical School, is then described. The chief effect of the construction work is shown to be a widespread underdrainage of the soft clays, brought about by pumping from the excavation. The distribution, rate and amount of the resulting settlements are reported in some detail.
A Motion Distillation Framework for Video Frame Interpolation

In recent years, we have seen the success of deep video enhancement models. However, the performance improvement of new methods has gradually entered a bottleneck period. Optimizing model structures or increasing training data brings less and less improvement. We argue that existing models with advanced structures have not fully demonstrated their performance and demand further exploration. In this study, we statistically analyze the relationship between motion estimation accuracy and video interpolation quality of existing video frame interpolation methods, and find that only supervising the final output leads to inaccurate motion and further affects the interpolation performance. Based on this important observation, we propose a general motion distillation framework that can be widely applied to flow-based and kernel-based video frame interpolation methods. Specifically, we begin by training a teacher model, which uses the ground-truth target frame and adjacent frames to estimate motion. These motion estimates then guide the training of a student model for video frame interpolation. Our experimental results demonstrate the effectiveness of this approach in enhancing performance across diverse advanced video interpolation model structures. For example, after applying our motion distillation framework, the CtxSyn model achieves a PSNR gain of 3.047 dB.
Incidence, management, and prognostic impact of arrhythmias in patients with Takotsubo syndrome: a nationwide retrospective cohort study

Abstract Aims Arrhythmia is a major complication of Takotsubo syndrome (TTS). However, its incidence, management, and prognostic impact remain to be elucidated in a large cohort. Methods and results We retrospectively identified 16 713 patients hospitalized for TTS between July 2010 and March 2021 from the Japanese Diagnosis Procedure Combination database. Serious arrhythmias were defined as ventricular tachycardia/fibrillation (VT/VF), 2nd-/3rd-degree atrioventricular block (AVB), sick sinus syndrome (SSS), or unspecified arrhythmias requiring device treatment. Patient characteristics and outcomes were compared based on the occurrence of serious arrhythmias. The overall incidence proportion of serious arrhythmias was 6.2% (n = 1036; 449 VT/VF, 283 2nd-/3rd-degree AVB, 133 SSS, 55 multiple arrhythmias, 116 others), which remained stable over 11 years. The arrhythmia group was younger, more often male, and exhibited greater impairment in activities of daily living (ADLs) and consciousness than the non-arrhythmia group. Although crude in-hospital mortality was higher in the arrhythmia group (9.6% vs. 5.0%, P < 0.001), the significant association between arrhythmias and mortality disappeared after adjustment for confounders (odds ratio = 1.15, 95% confidence interval = 0.90–1.49). Meanwhile, age, sex, ADLs, consciousness level, and Charlson comorbidity index were significantly associated with mortality. In the arrhythmia group, 254 (24.5%) patients received pacemakers (18.4%) or defibrillators (6.1%), which were implanted at a median of 8 and 19 days after admission, respectively. Conclusion Arrhythmias are not uncommon in TTS. Patients’ background characteristics, rather than arrhythmia itself, may be associated with in-hospital mortality. Given the reversibility of cardiac dysfunction in TTS, there may be unnecessary device implantations for arrhythmias occurring as sequelae to TTS, warranting further investigations.
Do Employers “Walk the Talk” After All? An Illustration of Methods for Assessing Signals in Underpowered Designs

This article presents two alternative methods to null hypothesis significance testing (NHST) for improving inferences from underpowered research designs. Post hoc design analysis (PHDA) assesses whether an NHST analysis generating null findings might otherwise have had sufficient power to detect effects of plausible magnitudes. Bayesian analysis with default priors offers advantages over NHST for assessing null findings and detecting signals in underpowered data. Both methods are illustrated by application to Pager and Quillian’s influential study on attitude-behavior correspondence. PHDA results suggest the original study lacked sufficient power to detect strong associations between employers’ attitudes and behaviors. Bayesian analysis confirms strong attitude–behavior associations cannot be ruled out given the data. Together, these results question a frequently cited conclusion about attitude–behavior incongruence in survey vignettes. Overall, the examples illustrate how these analytical tools can be useful for describing uncertainty surrounding estimates and for improving substantive and theoretical debates across sociology.
Movements and habitat use of female Roosevelt elk in relation to human disturbance on the Hoko and Dickey Game Management Units, Washington

The objectives of this study were to estimate elk movements, fidelity, home range size, and habitat use relative to sources of human disturbance. Thus, the predictions of this study were that: 1) elk movements would be modified by timber management and hunting activities; 2) measures of herd fidelity would decrease during the hunting period; 3) home range size would increase during the hunting period; and 4) dense even-aged timber stands would be used less than expected based upon habitat availability.
