description: This paper describes a technical implementation for the realization of the kilogram according to the new definition of the International System of Units (SI) of 2019. A commercially available high-vacuum prototype mass comparator from Sartorius serves as the basis. Mass comparators were used to directly compare kilogram prototypes, such as the International Prototype of the Kilogram (IPK or ℜ), with other kilogram prototypes to realize a calibration chain. Since the redefinition of the SI in 2019, the kilogram is defined by Planck's constant (ℎ). The Planck extension presented here is intended to make it possible, through technical modifications and some additional components, to convert high-vacuum mass comparators so that they can calibrate kilogram prototypes and mass standards according to the new definition. In addition, this should allow the continuous calibration of mass standards up to 1 kg in accordance with the E1 standard of OIML R 111-1 (2004). At the same time, all functions of the mass comparators are retained, which makes it possible to compare measurements according to the old and the new mass definition. During this elaboration, the functional principle of the Planck extension is described. Furthermore, measurement results from initial test measurements of 100 g with a relative standard deviation of 0.68 ppm are presented, analyzed, and evaluated. Based on the experience with the first prototype Planck extension, possible improvements and future work are proposed.

description: Context Serous cystic neoplasms of the pancreas are regarded as benign entities with rare malignant potential and are frequently resected. Objective The purpose of the study was to evaluate the usefulness of a multidisciplinary team (MDT) approach in decision making regarding the diagnosis and management of pancreatic serous cystic neoplasms. Methods A retrospective study of a prospective database involving 43 patients with serous cystic neoplasms was carried out. Patients who underwent multidisciplinary team evaluation (Group 1) were compared with patients who did not (Group 2) as regards demographic, clinical, radiological, surgical and pathological data. Uni-multivariate analyses were carried out. Results Uni-multivariate analysis showed that a multidisciplinary team approach was significantly related to the type of management, suggesting that MDT evaluation independently reduced the odds of surgery (odds ratio (OR) 0.1; 95% confidence interval (CI) 0.02-0.8; P=0.027). Age, second level imaging techniques, latero-lateral diameter, cranio-caudal diameter and Wirsung duct size differed between the two groups; however, the differences were not statistically significant. Conclusions A multidisciplinary team approach seems to be useful in proper decision making regarding the diagnosis and management of pancreatic serous cystic neoplasms.

description: Interactions and structure of organic carbonate + alkane, and 1-alkanol + organic carbonate mixtures have been investigated by means of a set of molar excess functions: enthalpies, volumes, isobaric heat capacities, or entropies; and considering internal pressure, liquid-liquid equilibria or permittivity data. In addition, the mentioned systems have been studied using the Flory model and the concentration-concentration structure factor formalism. The mixtures under consideration are characterized by dipolar interactions and by homocoordination (that is, by interactions between like molecules). In systems with a given solvent, dipolar interactions are weakened in the order: propylene carbonate (PC) > dimethyl carbonate (DMC) > diethyl carbonate (DEC). Comparison of mixtures containing DMC or DEC with those involving 2-propanone or 3-pentanone shows that dipolar interactions are not determined merely by values of the dipole moment, but they also depend on the group size. The enthalpies of the alkanol-carbonate interactions have been evaluated from calorimetric data. They are stronger in DMC solutions and become weaker when the alcohol size increases in mixtures with a given carbonate. Application of the Flory model to 43 systems of the type 1-alkanol + carbonate provides a mean relative standard deviation for excess molar enthalpy equal to 0.107. Results reveal that orientational effects decrease in the order DEC > PC > DMC. Orientational effects are particularly relevant in methanol or ethanol + DEC mixtures. Interestingly, the mentioned effects are weaker in 1-alkanol + DMC mixtures than in DMC + alkane systems. A similar trend is observed in DEC solutions when the considered alcohol is longer than ethanol.

description: Sulfur dioxide (SO$_2$) and nitrogen monoxide (NO) are some of the gas impurities present in the carbon dioxide (CO$_2$) separated from fume using post combustion capture process. Even in a small amount, these impurities may have an impact on storage process development. The dissolution of such gases in aqueous phase is part of the studies carried out to develop processes and analyze the risks in case of geological storage. The enthalpies of solution of SO$_2$ and NO in water were here investigated by calorimetry, using a flow calorimetric technique. The enthalpies of solution were determined at 323.15 K and 373.15 K for sulfur dioxide, and at 323.15 K for nitrogen monoxide. The experimental enthalpy data were used together with available solubility data to test thermodynamic models representative of vapor-liquid equilibrium.

description: Context Gastrointestinal (GI) involvement is present in about one quarter of cases of neurofibromatosis type 1 (NF1). Adenocarcinomas have been reported in several organs. Gastrointestinal stromal tumors are the most common GI lesion seen in NFI. GISTs in combination with ampullary neuroendocrine tumors in NF-1 have been reported rarely. Case report We present the case of a 44-year-old man who presented with a history of obstructive jaundice and weight loss. Investigations revealed a pancreatic tumor associated with a common bile duct (CBD) stricture. At operation, an ampullary adenocarcinoma that infiltrated into the head of pancreas with an adjacent somatostatinoma was found. In addition, a small bowel GIST was present. Conclusions Mixed periampullary adenocarcinoma and somatostatinoma in a patient with NF1 has only been previously reported once. The current case highlights the spectrum of associated tumor types which can be seen in association with NF1. Patients with NF1 who present with jaundice and weight loss should be investigated in the usual manner with increased suspicion for duodenal and ampullary tumors.

description: Understanding and analyzing student behavior is paramount in enhancing online learning, and this thesis delves into the subject by presenting an in-depth analysis of student behavior and score prediction in the ASSISTments online learning platform. We used data from the EDM Cup 2023 Kaggle Competition to answer four key questions. First, we explored how students seeking hints and explanations affect their performance in assignments, shedding light on the role of guidance in learning. Second, we looked at the connection between students mastering specific skills and their performance in related assignments, giving insights into the effectiveness of curriculum alignment. Third, we identified important features from student activity data to improve grade prediction, helping identify at-risk students early and monitor their progress. Lastly, we used graph representation learning to understand complex relationships in the data, leading to more accurate predictive models. This research enhances our understanding of data mining in online learning, with implications for personalized learning and support mechanisms.

description: Context There is little reported experience of irreversible electroporation (IRE) of locally advanced pancreatic tumors (LAP). In literature, few data reported complications. In particular vascular vasoconstriction miming splenic infarcts in humans has never been found. Case report This report describes the onset of asymptomatic multiple little splenic perfusion defects after the treatment of a LAP localized in the boby-tail portion of the pancreas with the application of five percutaneous probes for IRE, in a 79 year-old man. Splenic artery was regularly patent but entirely trapped in the tumor. Conclusion To the best of our knowledge, until now, no experience concerning percutaneous IRE of pancreatic cancer described that phenomenon. The cause could not be established with certainty and “vascular lock" may be a valid hypothesis. Additional studies are necessary to evaluate its frequency and its exact pathophysiological cause in humans.

Skeletal Data Matching and Merging from Multiple RGB-D Sensors for Room-Scale Human Behaviour Tracking

Year: 2024
Subjects: subject: Human-Computer Interaction (cs.HC)

description: A popular and affordable option to provide room-scale human behaviour tracking is to rely on commodity RGB-D sensors %todo: such as the Kinect family of devices? as such devices offer body tracking capabilities at a reasonable price point. While their capabilities may be sufficient for applications such as entertainment systems where a person plays in front of a television, RGB-D sensors are sensitive to occlusions from objects or other persons that might be in the way in more complex room-scale setups. To alleviate the occlusion issue but also in order to extend the tracking range and strengthen its accuracy, it is possible to rely on multiple RGB-D sensors and perform data fusion. Unfortunately, fusing the data in a meaningful manner raises additional challenges related to the calibration of the sensors relative to each other to provide a common frame of reference, but also regarding skeleton matching and merging when actually combining the data. In this paper, we discuss our approach to tackle these challenges and present the results we achieved, through aligned point clouds and combined skeleton lists. These results successfully enable unobtrusive and occlusion-resilient human behaviour tracking at room scale, that may be used as input for interactive applications as well as (possibly remote) collaborative systems.

description: To enhance workspace awareness for mixed-presence meetings with large displays, previous work propose digital cues to share gestures, gaze, or entire postures. While such cues were demonstrated useful in horizontal or smaller workspaces, efforts have focused on isolated elements in controlled settings. It is unknown what needs would emerge with a more realistic setting and how they could be addressed with workspace awareness cues. In this paper, we report on the results of a focus group, centred around users' perceptions while testing a mixed-presence scenario on wall-sized displays. We analyse the gathered comments using Gutwin and Greenberg's workspace awareness framework to identify the most relevant needs. Our results lead to a refinement of the original framework for wall-sized displays and in particular to a categorization into three types of workspace awareness components (i) the Environment, (ii) Actions and (iii) Attention.

description: Robot dogs are receiving increasing attention in various fields of research. However, the number of studies investigating their potential usability on construction sites is scarce.
 The construction industry implies several human resource-demanding tasks such as safety monitoring, material transportation, and site inspections. Robot dogs can address some of these challenges by providing automated support and lowering manual effort.
 In this paper, we investigate the potential usability of currently available robot dogs on construction sites in terms of focusing on their different specifications and on-site requirements to support data acquisition. In addition, we conducted a real-world experiment on a large-scale construction site using a quadruped robot.
 In conclusion, we consider robot dogs to be a valuable asset for monitoring intricate construction environments in the future, particularly as their limitations are mitigated through technical advancements.

description: One primary reason for the current epidemic of digestive disorders might be chronic metabolic acidosis, which is extremely common in the modern population. Chronic metabolic acidosis primarily affects two alkaline digestive glands, the liver, and the pancreas, which produce alkaline bile and pancreatic juice with a large amount of bicarbonate. Even small acidic alterations in the bile and pancreatic juice pH can lead to serious biochemical/biomechanical changes. The pancreatic digestive enzymes require an alkaline milieu for proper function, and lowering the pH disables their activity. It can be the primary cause of indigestion. Acidification of the pancreatic juice decreases its antimicrobial activity, which can lead to intestinal dysbiosis. Lowering the pH of the pancreatic juice can cause premature activation of the proteases inside the pancreas with the potential development of pancreatitis. The acidification of bile causes precipitation of the bile acids, which irritate the entire biliary system and create bile stone formation. Aggressive mixture of the acidic bile and the pancreatic juice can cause erratic contractions of the duodenum’s walls and subsequent bile reflux into the stomach and the esophagus. Normal exocrine pancreatic function is the core of proper digestion. Currently, there is no effective and safe treatment for enhancing the exocrine pancreatic function. Restoring normal acid-base homeostasis can be a useful tool for pathophysiological therapeutic approaches for various gastrointestinal disorders. There is strong research and practical evidence that restoring the HCO3- capacity in the blood can improve digestion.

description: Die Frage nach der Rechtsnatur der Personengesellschaft ist rechtsgebietsübergreifend umstritten. Im Kern besteht Uneinigkeit darüber, ob die Personengesellschaft lediglich die Gesamtheit ihrer Gesellschafter abbildet oder ob sie ein davon getrennt zu betrachtendes Rechtssubjekt darstellt. Für das Zivilrecht wird dieser Streit durch die Regelung des § 124 HGB sowie durch die Entscheidung des BGH vom 29.1.2001 – II ZR 331/00 (ARGE Weißes Roß) zugunsten der Rechtssubjektivität von Personengesellschaften weitestgehend entschärft. Im Einkommensteuerrecht hingegen ist die Frage bis heute nicht abschließend geklärt. Dies spiegelt sich in der ambivalenten Rechtsprechung des BFH zur Besteuerung von Personengesellschaften wider. Der folgende Beitrag setzt sich kritisch mit dieser Judikatur auseinander und untersucht hierauf bezogene Entwicklungen in der jüngeren Rechtsprechung.

description: Context The major goals that must be achieved during pancreaticoduodenectomy (PD) include reduction of postoperative hemorrhage and/or operating time. We herein describe a new technique for PD examining right posterior approach PD. Methods From January 2012 to December 2013, 116 patients underwent PD for periampullary or pancreatic disease. Of these 116 patients, 56 cases were surgically treated for pancreas head or periampullary malignancy and were studied for blood loss volume and length of operation. Results An interesting issue in the present study was related to operating time and intra-operative blood loss. The median blood loss volume and operating time were 349 mL (35-3,636 mL) and 276 min (188-467 min), respectively, in patients who underwent a right posterior-approach PD. Conclusion The estimated operative blood loss volume and operative time are lower in right posterior approach PD, probably due to clearly detection a route of the inferior pancreaticoduodenal artery from the SMA and following early ligation of the inferior pancreaticoduodenal artery and reduced congestion of the pancreatic head.

description: The nuclear stellar disc (NSD) is a flat and dense stellar structure at the centre of the Milky Way. Previous work has identified the presence of metal-rich and metal-poor stars in the NSD, suggesting that they have different origins. The recent publication of photometric, metallicity, proper motion, and orbital catalogues allows the NSD stellar population to be characterised with unprecedented detail. We aim to explore the proper motions and orbits of NSD stars with different metallicities to assess whether they have different origins and to better understand the metallicity distribution in the NSD. We distinguished between metal-rich and metal-poor stars by applying a Gaussian mixture model, as done in previous work, and analysed the proper motions, orbits, and spatial distribution of stars with different metallicities. We find that metal-rich stars exhibit a lower velocity dispersion, suggesting that they trace a kinematically cooler component compared to metal-poor ones. Furthermore, z-tube orbits are predominant among metal-rich stars, while chaotic/box orbits are more common among metal-poor ones. We also find that metal-rich and metal-poor stars show a similar extinction and are present throughout the analysed regions. As a secondary result, we detected a metallicity gradient in the metal-rich population with higher metallicity towards the centre of the NSD and a tentative gradient for the metal-poor stars, which is consistent with previous studies that did not distinguish between the two populations. Our results suggest that metal-rich stars trace the NSD, whereas metal-poor ones are related to the Galactic bar and probably constitute Galactic bar interlopers and/or are NSD stars that originated from accreted clusters. The detected metallicity gradients aligns with the currently accepted inside-out formation of the NSD.

description: Integrable operators arise in random matrix theory, where they describe the asymptotic eigenvalue distributions of large self-adjoint random matrices from the generalized unitary ensembles. This paper gives sufficient conditions for an integrable operator to be the square of a Hankel operator, and applies the condition to the Airy, associated Laguerre, modified Besses and Whittaker functions.

description: Context Oral vanadyl sulfate (vanadium) has potent hypoglycemic effects in diabetes animals, but data about its actions on pancreatic beta-cells (BC) ultrastructure is limited. Objective Partial diabetic rats were treated with vanadium and insulin injection and their effects on BC ultrastructure are studied. Methods Male rats were made diabetic with intravenous streptozotocin injection (STZ, 40 mg/kg). Animals were randomly divided to control (CD), vanadium-treated (1 mg/mL VOSO4 + 5H2O in base solution, VTD) and insulin-treated (80 U/kg/day NPH insulin injection, ITD) diabetic groups. Treatments started 10 days after STZ injection and terminated after 2 months. Intermittent tail blood samples were taken for measurements of blood glucose (BG) and plasma insulin (PI). Finally animals were sacrificed and pancreata prepared for assessments of BC ultrastructure, islets histology and insulin immunoreactivity (IIR). Results Vanadium decreased BG (P<0.0001), elevated the reduced PI (P<0.001), prevented islet atrophy and restored BC ultrastructure. Low BG seen during treatment in VTD and ITD only persisted in VTD after vanadium withdrawal. Hyperglycemia worsened in CD and repaired in ITD shortly after insulin withdrawal. CD islets were atrophied, had scattered IIR spots. BC had pyknotic nuclei, vacuolated cytoplasm and few tiny insulin secretory granules. VTD islets looked normal with compact centered IIR spots. BC had well-developed endoplasmic reticulum, many insulin secretory granules and mitochondria. ITD islet structure was slightly better than CD and BC had some immature insulin secretory granules. Conclusion The trophic actions of vanadium in diabetic rats effectively renovated beta cell ultrastructure and prevented pancreatic islets atrophy, whereas the relief of glucotoxicity seen with insulin treatment could repair some beta cells and partially prevented islet atrophy.

description: Suppose that $Γ$ is a continuous and self-adjoint Hankel operator on $L^2(0, \infty)$ and that $Lf=-(d/dx(a(x)df/dx))+b(x)f(x)$ with $a(0)=0$. If $a$ and $b$ are both quadratic, hyperbolic or trigonometric functions, and $ϕ$ satisfies a suitable form of Gauss's hypergeometric equation, or the confluent hypergeometric equation, then $LΓ=ΓL$. The paper catalogues the commuting pairs $Γ$ and $L$, including important cases in random matrix theory. There are also results proving rapid decay of the singular numbers of Hankel integral operators with kernels that are analytic and of exponential decay in the right half plane.

description: Context LigaSureTM is considered safe in performing pancreaticoduodenectomy (PD). However, no data are available regarding the possible damage of tissues at the resection margins and the impact thereof on histologic margin assessment. Objective This study compares the degree of histologic damage to the resection margins when using LigaSureTM (Group 1) or traditional ligature (Group 2). Methods Both groups included 8 consecutive patients who underwent PD at Karolinska Institute in December 2013 (Group 1) or earlier (Group 2) by the same surgeon (M.D.C.). The quality of tissues at the circumferential margins was compared between both groups by scoring for three different kinds of damage: tissue fragmentation, hemorrhage, and cell damage. Results The mean score for fragmentation was 1.3 (Group 1) versus 1.7 (Group 2; P=0.1). For hemorrhage the mean score was 0.8 (Group 1) versus 1.5 (Group 2; P=0.04). The mean score for cell damage was 1.4 (Group 1) compared to 1.2 (Group 2; P=0.1). Conclusions LigaSureTM does not cause tissue damage that could affect histologic margin assessment in PD specimens.

description: Der Aufsatz thematisiert das sozialrechtliche Problem des Anspruchs auf Krankengeld im Fall einer Organ- oder Gewebespende (§ 44a SGB V). Auch wenn der nachträglich eingefügte § 44a SGB V auf den ersten Blick im Regelungsgefüge der Krankengeldnormen von geringer Relevanz zu sein scheint, darf dessen Bedeutung nicht übersehen werden. Die Norm bezweckt unter anderem, der mangelnden Bereitschaft in der Bevölkerung zur Organspende entgegenzuwirken, indem sie die gesetzliche Absicherung bei Arbeitsunfähigkeit infolge einer Organspende sicherstellt. Aufgrund der finanziellen Abhängigkeit vom Einkommen mag es für den Entschluss zur Organspende für viele durchaus ein ausschlaggebendes Kriterium sein, im Fall einer Spende auch weiter finanziell abgesichert zu sein.

description: We consider the spectrum of the staggered Dirac operator with SU(2) gauge fields. Our study is motivated by the fact that the antiunitary symmetries of this operator are different from those of the SU(2) continuum Dirac operator. In this contribution, we investigate in some detail staggered eigenvalue spectra close to the free limit. Numerical experiments in the quenched approximation and at very large $β$-values show that the eigenvalues occur in clusters consisting of eight eigenvalues each. We can predict the locations of these clusters for a given configuration very accurately by an analytical formula involving Polyakov loops and boundary conditions. The spacing distribution of the eigenvalues within the clusters agrees with the chiral symplectic ensemble of random matrix theory, in agreement with theoretical expectations, whereas the spacing distribution between the clusters tends towards Poisson behavior.

description: Context Erlotinib is a selective epidermal growth factor receptor tyrosine kinase inhibitor used as a target therapy against non-small lung cancer and advanced pancreatic cancer. A regimen of erlotinib plus gemcitabine has been proven to prolong overall survival in the patient with advanced pancreatic cancer. In addition to common adverse effects, such as diarrhea, mucositis and skin rash (acne form eruptions), acute interstitial lung disease (ILD) has been reported as an infrequent but potentially fatal complication. We here report a case of a Japanese patient with erlotinib-induced ILD in whom high-dose corticosteroid therapy was successful. Case report A fifty-five-year-old male with cancer of the head of the pancreas with multiple liver metastases started treatment with gemcitabine plus erlotinib. On the 13th day of erlotinib treatment, he had high fever. Chest computed tomography (CT) scan showed a diffuse ground-glass like infiltration of both lungs. He was diagnosed with ILD, and high-dose corticosteroid therapy was started. Two weeks after the introduction of steroid therapy, the reticular shadow faded away on CT. He was successfully treated with corticosteroid for erlotinib-induced acute ILD although he died 6 months after the initiation of chemotherapy owing to disease progression. Conclusion we showed a case of a successfully treated Japanese patient of erlotinib-induced ILD. Because erlotinib-induced ILD would frequently occur in Japanese patients, closer attention to ILD should be paid for Japanese patients than in Western populations. If erlotinib-induced ILD occurs, a high-dose corticosteroid therapy would be a useful option of treatment.
