description: Reinforcement Learning (RL) has recently impressed the world with stunning results in various applications. While the potential of RL is now well-established, many critical aspects still need to be tackled, including safety and stability issues. These issues, while partially neglected by the RL community, are central to the control community which has been widely investigating them. Model Predictive Control (MPC) is one of the most successful control techniques because, among others, of its ability to provide such guarantees even for uncertain constrained systems. Since MPC is an optimization-based technique, optimality has also often been claimed. Unfortunately, the performance of MPC is highly dependent on the accuracy of the model used for predictions. In this paper, we propose to combine RL and MPC in order to exploit the advantages of both and, therefore, obtain a controller which is optimal and safe. We illustrate the results with a numerical example in simulations.

description: Context Carcinoembryonic antigen analysis of pancreatic cyst fluid is the tumor marker of choice for preoperatively differentiating mucinous from non-mucinous cystic lesions. Objective We aim to determine the most accurate cyst carcinoembryonic antigen cut-off value for distinguishing mucinous cysts from non-mucinous cysts with a focus on discriminating intraductal papillary mucinous neoplasms. Methods The results of pancreatic cyst aspiration carcinoembryonic antigen levels from a single center were retrospectively collected and evaluated for a diagnosis of a mucinous cyst and an assessment of malignancy using surgical histology as the diagnostic standard in 86 patients. Results The median cyst carcinoembryonic antigen level (ng/mL) was significantly higher in mucinous cysts compared with non-mucinous cysts (218 vs. 4.4; P=0.0006) and in intraductal papillary mucinous neoplasms compared with non-mucinous cysts (135 vs. 4.4; P=0.0027). A cyst carcinoembryonic antigen cut-off of 30.7 ng/mL was most accurate (87.2%) for differentiating mucinous from non-mucinous cysts and specifically for differentiating intraductal papillary mucinous neoplasms from non-mucinous cysts (82.7%). Cyst carcinoembryonic antigen levels were not significantly different between malignant and non-malignant mucinous cysts (68.5 vs. 238.1; P=0.51). Conclusions Pancreatic cyst fluid carcinoembryonic antigen can accurately differentiate histologically verified mucinous lesions, including intraductal papillary mucinous neoplasms, from non-mucinous lesions with an optimal cut-off that is much lower than previously reported values. Cyst carcinoembryonic antigen levels are not a reliable predictor of malignancy.

description: Context Pulmonary tuberculosis and especially multi-drug-resistant tuberculosis remain a pressing health problem. Objective The aim of this study was to establish how often standard preparations for the treatment of tuberculosis, such as isoniazid and rifampicin, lead to acute pancreatitis. Methods Two hundred and eighty patients with pulmonary tuberculosis were investigated by clinical chemistry and ultrasonography to determine in how many cases the use of isoniazid and rifampicin was followed by elevation of pancreatic isoamylase or lipase or by sonographic signs of acute pancreatitis with and without occurrence of acute upper abdominal symptoms. Results Acute pancreatitis definitely occurred in 22 (8%) and probably in 36 (13%) of the patients. In 21 (8%) there was merely an asymptomatic serum elevation of pancreatic enzymes and no pathologic sonographic signs in the pancreas. Conclusions Acute pancreatitis is a frequent occurrence after administration of isoniazid and rifampicin and must be considered whenever upper abdominal symptoms are found in patients treated with these drugs.

description: Fluid-structure interaction (FSI) problems are pervasive in the computational engineering community. The need to address challenging FSI problems has led to the development of a broad range of numerical methods addressing a variety of application-specific demands. While a range of numerical and experimental benchmarks are present in the literature, few solutions are available that enable both verification and spatiotemporal convergence analysis. In this paper, we introduce a class of analytic solutions to FSI problems involving shear in channels and pipes. Comprised of 16 separate analytic solutions, our approach is permuted to enable progressive verification and analysis of FSI methods and implementations, in two and three dimensions, for static and transient scenarios as well as for linear and hyperelastic solid materials. Results are shown for a range of analytic models exhibiting progressively complex behavior. The utility of these solutions for analysis of convergence behavior is further demonstrated using a previously published monolithic FSI technique. The resulting class of analytic solutions addresses a core challenge in the development of novel FSI algorithms and implementations, providing a progressive testbed for verification and detailed convergence analysis.

description: Context Post-operative haemorrhage is a known complication of hepatopancreatobiliary surgery. Prompt treatment minimizes mortality and morbidity; however, there is currently little uniformity in the management of this complication. Objective The total numbers of pancreatectomies or liver resections were identified using hospital episode statistic data. Methods Patients who experienced post-operative bleeding were identified with keyword searches of all discharge letters, imaging reports and the theatre-coding database for the period between January 2005 and December 2011. Treatment modalities for control of haemorrhage as well as morbidity, mortality, length of stay and survival were examined. Results Thirty-four of the 768 pancreatic and liver resections performed experienced post-operative haemorrhage. More patients bled following pancreatectomies (6.1%) compared to hepatectomies (2.5%). Bleeding was controlled using endoscopic, interventional radiological or surgical methods; re-laparotomy provided definitive management in the majority of patients. Post-pancreatectomy haemorrhage was associated with significantly increased mortality (P=0.004). Length of stay was increased following haemorrhage post-pancreatectomy or hepatectomy (P<0.05). Conclusions Our study highlights the substantial increase in mortality and length of stay following post-pancreatectomy and post-hepatectomy haemorrhage. Re-laparotomy was frequently required for control of bleeding. Our proposed management algorithm based on the timing and site of bleeding may standardize treatment in this heterogeneous group.

description: Context Multifocal or diffuse mucinous cystic neoplasm are uncommon and may be difficult to distinguish from multifocal intra-ducal mucinous neoplasm or diffuse serous cystadenoma. Case report A forty-seven-year old lady with vague abdominal pain was noted to have cystic lesions ranging from 5 to 20 mm throughout her pancreas. The cysts had enlarged over several years of observation. There was no evidence of pancreatic duct dilatation or communication with the pancreatic duct on magnetic resonance imaging. Cyst fluid analysis for carcinoembryonic antigen and amylase were non-diagnostic. A total pancreatectomy was performed, with histology confirming numerous cysts lined by mucus producing cells, without obvious ovarian-like stroma. The stroma did however demonstrate positive staining for oestrogen receptor and smooth muscle actin. These findings were most consistent with a mucinous cystic neoplasm, despite the apparent absence of typical ovarian like stroma. Conclusion Multifocal or diffuse pancreatic mucinous cystic neoplasm are uncommon and may be suspected when imaging demonstrates multiple pancreatic cysts without communication with the pancreatic duct or pancreatic duct dilation. Surgical resection is indicated due to the increased risk of malignancy.

description: This paper proposes a new equivalent circuit model for rechargeable batteries by modifying a double-capacitor model proposed in [1]. It is known that the original model can address the rate capacity effect and energy recovery effect inherent to batteries better than other models. However, it is a purely linear model and includes no representation of a battery's nonlinear phenomena. Hence, this work transforms the original model by introducing a nonlinear-mapping-based voltage source and a serial RC circuit. The modification is justified by an analogy with the single-particle model. Two parameter estimation approaches, termed 1.0 and 2.0, are designed for the new model to deal with the scenarios of constant-current and variable-current charging/discharging, respectively. In particular, the 2.0 approach proposes the notion of Wiener system identification based on maximum a posteriori estimation, which allows all the parameters to be estimated in one shot while overcoming the nonconvexity or local minima issue to obtain physically reasonable estimates. An extensive experimental evaluation shows that the proposed model offers excellent accuracy and predictive capability. A comparison against the Rint and Thevenin models further points to its superiority. With high fidelity and low mathematical complexity, this model is beneficial for various real-time battery management applications.

description: Context Long-standing diabetes mellitus results in autonomic nervous system dysfunction, leading to gastroparesis and cholecystoparesis. The latter can result in hydropic gallbladder, a condition that arises from the accumulation of mucinous secretions within the gallbladder, usually caused by obstruction of the cystic duct, but not in the case of the patients with diabetes that we have illustrated. Case report We describe three patients who presented with non-specific abdominal discomfort at the time of admission for complications of poorly controlled diabetes and were subsequently found to have hydropic gallbladder. We theorize that hydropic gallbladder may be a result of a natural progression of gallbladder dysfunction in poorly controlled diabetics with autonomic neuropathy. In our cases the risk of perioperative mortality was high at the time of presentation. No surgical intervention was performed except in one case with the most significant sized gallbladder, and underwent a temporizing cholecystostomy. Conclusions The development of hydropic gallbladder in patients with non-obstructed cystic ducts highlights the complexities of management of patients with functional biliary pain. The rome committee on functional biliary and pancreatic disorders has defined the characteristics of this pain. There is a need for guidelines to direct appropriate assessment of hydropic gallbladder in diabetics and also to determine the indications for cholecystectomy.

description: Context The lifelong risk of post-splenectomy overwhelming sepsis is major complication after splenectomy. Laparoscopic distal pancreatectomy is an accepted as safe, and adequate procedure for pancreatic pathologies requiring resection of the distal part of the pancreas. However, attempts to preserve the spleen are not always successful and sometimes require unnecessary splenectomy. Spleen autotransplantation can be regarded as inducing iatrogenic splenosis in the abdominal cavity. Case report In this report, we present a case of spleen autotransplantation (about 30 g of splenic tissue) following laparoscopic distal pancreatectomy and inadvertent splenectomy for benign intraductal papillary tumor of the pancreas. Conclusion This procedure may be the last option spleen preservation considered in the era of laparoscopic distal pancreatectomy.

description: There is a growing need for vehicle positioning information to support Advanced Driver Assistance Systems (ADAS), Connectivity (V2X), and Automated Driving (AD) features. These range from a need for road determination (<5 meters), lane determination (<1.5 meters), and determining where the vehicle is within the lane (<0.3 meters). This work examines the performance of Global Navigation Satellite Systems (GNSS) on 30,000 km of North American highways to better understand the automotive positioning needs it meets today and what might be possible in the near future with wide area GNSS correction services and multi-frequency receivers. This includes data from a representative automotive production GNSS used primarily for turn-by-turn navigation as well as an Inertial Navigation System which couples two survey grade GNSS receivers with a tactical grade Inertial Measurement Unit (IMU) to act as ground truth. The latter utilized networked Real-Time Kinematic (RTK) GNSS corrections delivered over a cellular modem in real-time. We assess on-road GNSS accuracy, availability, and continuity. Availability and continuity are broken down in terms of satellite visibility, satellite geometry, position type (RTK fixed, RTK float, or standard positioning), and RTK correction latency over the network. Results show that current automotive solutions are best suited to meet road determination requirements at 98% availability but are less suitable for lane determination at 57%. Multi-frequency receivers with RTK corrections were found more capable with road determination at 99.5%, lane determination at 98%, and highway-level lane departure protection at 91%.

description: This paper studies performance preserving event design in nonlinear event-based control systems based on a local L2-type performance criterion. Considering a finite gain local L2-stable disturbance driven continuous-time system, we propose a triggering mechanism so that the resulting sampled-data system preserves similar disturbance attenuation local L2-gain property. The results are applicable to nonlinear systems with exogenous disturbances bounded by some Lipschitz-continuous function of state. It is shown that an exponentially decaying function of time, combined with the proposed triggering condition, extends the inter-event periods. Compared to the existing works, this paper analytically estimates the increase in intersampling periods at least for an arbitrary period of time. We also propose a so-called discrete triggering condition to quantitatively find the improvement in inter-event times at least for an arbitrary number of triggering iterations. Illustrative examples support the analytically derived results.

description: Let $A, B \subseteq \mathbb{N}$ be two finite sets of natural numbers. We say that $B$ is an additive divisor for $A$ if there exists some $C \subseteq \mathbb{N}$ with $A = B+C$. We prove that among those subsets of $\{0, 1, \ldots, k\}$ which have $0$ as an element, the full interval $\{0, 1, \ldots,k\}$ has the most divisors. To generalize to sets which do not have $0$ as an element, we prove a correspondence between additive divisors and lunar multiplication, introduced by Appelgate, LeBrun and Sloane (2011) in their study of a kind of min/max arithmetic. The number of binary lunar divisors is related to compositions of integers which are restricted in that the first part is greater or equal to all other parts. We establish some bounds on such compositions to show that $\{1, \ldots, k\}$ has the most divisors among all subsets of $\{0, 1, \ldots, k\}$. These results resolve two conjectures of LeBrun et al. regarding the maximal number of lunar binary divisors, a special case of a more general conjecture about lunar divisors in arbitrary bases. We resolve this third conjecture by generalizing from sum-sets to sum-multisets.

Because it is normal tissue with abnormal figuration, acinar cell transformation is also named. Case report We reported a thirty-seven-year-old female noticed to have a cystic lesion closely in contact with the pancreatic tail by abdominal CT scan. After operation, the cystic lesion was analyzed and acinar cell cystadenoma arising from retroperitoneum was confirmed. Conclusion Literature review revealed only one case of retroperitoneal acinar cell cystadenoma was reported before and the pathogenesis is still unknown.

description: Context Laparoscopic distal pancreatectomy is a widely accepted treatment for non-malignant lesions of the left pancreas. However, the role of laparoscopy in more complex procedures such as pancreaticoduodenectomy or treatment of pancreatic adenocarcinoma remains controversial. Case report A seventy-seven-year-old woman underwent surgery twice: first for a PADC of the tail infiltrating the spleen and left kidney, and then for a second PADC of the neck and head of the pancreas diagnosed during follow-up (11 months) of the first tumor. In both procedures a totally laparoscopic approach was applied. The first procedure was an en-bloc resection including the left kidney, spleen and left pancreas. Final diagnosis showed a PADC (49x42x40 mm) involving one of the 17 lymph nodes harvested (R0). Postoperative course was uneventful, and lasted five days. Later, due to the appearance of a new tumor in the right pancreas, an extended pylorus-preserving PD was performed with the patient in supine position with the legs apart. In the postoperative period she presented chylous ascites and required hospitalization for 17 days. Definitive biopsy showed a 2 cm PADC (PanIn 2 and 3 lesions in the rest of the gland). Two out of 21 nodes isolated were found to be affected (R0). No chemotherapy was administered after the second operation. Conclusions Our report may help to redefine the limits of laparoscopy in pancreatic oncologic surgery. It describes several features of added technical difficulty, and may prompt further reflection on the current limits and indications of laparoscopic pancreatectomy.

description: Context Cystic fibrosis is the most common autosomal recessive genetic disease in Caucasian population. Extending knowledge about the molecular pathology on the one hand allows better delineation of the mutations in the cystic fibrosis transmembrane regulator gene and the other to dramatically increase the predictive power of molecular testing. Case report This study wants to underline that the identification of individuals with atypical cystic fibrosis can sometimes present particular difficulties of interpretation. Conclusion On that ground, if there is a strong clinical suspicion, it is always advisable the biochemical study by performing the sweat test, followed by sequencing of the cystic fibrosis transmembrane regulator gene.

description: Abstract
The purpose of this study is to analyze: 1) How is responsibility for pollution and or destruction of the environment? 2) What is the process of resolving disputes over pollution and / or environmental destruction? 3) What is the legal responsibility for coastal pollution by factory waste that is fair? The research method used is empirical juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) In the context of environmental management or control of all natural resources and the environment, the responsibility inherent in it is not only owned by the state, but it is also related to the company. Companies or corporations managing B3 waste have the obligation to carry out social responsibility for the community and the environment around the company's activities. 2) Law Number 32 of 2009 Article 87 regulates the obligation of the person responsible for the business to compensate the person or environment who is harmed. In addition to victims, environmental organizations can also hold civil liability to business actors. However, if the lawsuit is made by an environmental organization, the request that can be made is limited to taking certain actions, except for real costs or expenses. So that people who suffer losses due to pollution and / or environmental destruction can bring lawsuits together by means of class actions. The most important thing in carrying out this lawsuit, community groups can take ways outside the court known as alternative dispute resolution mechanisms According to Article 1 point (5). 3) Regulation of the Minister of Environment Number 13 of 2011 concerning Compensation for Pollution and/or Environmental Damage. "Compensation is a cost that must be borne by the person responsible for activities and/or businesses due to pollution and/or environmental damage". Every person or legal entity that pollutes the environment and is proven, then he must be responsible for the environmental damage that has been done.

description: Context The B islets isolated from 3-5 day old chick respond well to glucose challenge in a similar fashion to those isolated from mouse pancreas. Objective To compare insulin secretory response of chick B islets with that of human islet equivalents generated from stem cells. Methods Human umbilical cord mesenchymal stem cells were differentiated into hIEqs employing three step sequential serum free protocols. Results Immunofluorescence staining demonstrated insulin, C peptide and Glut 2 positivity of both these islets. Static insulin stimulation of these islets in response to glucose, metformin and gamma amino butyric acid resulted in increased insulin secretion as compared to basal glucose stimulation. Our results demonstrate that insulin secretory response of Chick B islets to metformin and gama amino butyric acid is comparable to those of hIEqs. Moreover, both chick and hIEqs could be successfully cryopreserved and revived in a commercially available cryomix (Cryostore 5®), indicating resemblance in their behavior at sub-zero temperatures. Conclusion Present study advocates Chick islets as an alternative source for diabetes research and islet banking.

description: Immunization with an inactivated virus is one of the strategies currently being tested towards developing a SARS-CoV-2 vaccine. One of the methods used to inactivate viruses is exposure to high doses of ionizing radiation to damage their nucleic acids. Although gamma-rays effectively induce lesions in the RNA, envelope proteins are also highly damaged in the process. This in turn may alter their antigenic properties, affecting their capacity to induce an adaptive immune response able to confer effective protection. Here, we modelled the impact of sparsely and densely ionizing radiation on SARS-CoV-2 using the Monte Carlo toolkit Geant4-DNA. With a realistic 3D target virus model, we calculated the expected number of lesions in the spike and membrane proteins, as well as in the viral RNA. We show that gamma-rays produce significant spike protein damage, but densely ionizing charged particles induce less membrane damage for the same level of RNA lesions, because a single ion traversal through the nuclear envelope is sufficient to inactivate the virus. We propose that accelerated charged particles produce inactivated viruses with little structural damage to envelope proteins, thereby representing a new and effective tool for developing vaccines against SARS-CoV-2 and other enveloped viruses.

description: The Ehrhart quasipolynomial of a rational polytope $P$ encodes the number of integer lattice points in dilates of $P$, and the $h^*$-polynomial of $P$ is the numerator of the accompanying generating function. We provide two decomposition formulas for the $h^*$-polynomial of a rational polytope. The first decomposition generalizes a theorem of Betke and McMullen for lattice polytopes. We use our rational Betke--McMullen formula to provide a novel proof of Stanley's Monotonicity Theorem for the $h^*$-polynomial of a rational polytope. The second decomposition generalizes a result of Stapledon, which we use to provide rational extensions of the Stanley and Hibi inequalities satisfied by the coefficients of the $h^*$-polynomial for lattice polytopes. Lastly, we apply our results to rational polytopes containing the origin whose duals are lattice polytopes.

description: We introduce a notion of Milnor square of stable $\infty$-categories and prove a criterion under which algebraic K-theory sends such a square to a cartesian square of spectra. We apply this to prove Milnor excision and proper excision theorems in the K-theory of algebraic stacks with affine diagonal and nice stabilizers. This yields a generalization of Weibel's conjecture on the vanishing of negative K-groups for this class of stacks.
