description: Context Paragangliomas are rare tumours of neural crest origin. Extra-adrenal pancreatic paragangliomas are exceptionally rare. Case report A 66-year-old man with abdominal pain was noted to have a complex pancreatic head and uncinate process mass on imaging. He underwent complete resection by pancreaticoduodenectomy with final pathology confirming a 6 cm paraganglioma without evidence of metastases. On histology the tumour was arising from the retroperitoneum and abutting the pancreas. The patient was disease free at 14-month follow-up. Conclusion Pancreatic paragangliomas represent in many cases the retroperitoneal extension of a paraganglioma into the pancreas rather than a true pancreatic neoplasm. Although generally benign, the risk of malignant transformation justifies aggressive management.

description: We present the results of the first four (quasi-)simultaneous radio (ATCA), X-ray (Swift, RXTE), and Gamma-ray (INTEGRAL) observations of the black hole candidate IGR J17091-3624, performed in February and March 2011. The X-ray analysis shows that the source was in the hard state, and then it transited to a soft intermediate state. We study the correlated radio/X-ray behaviour of this source for the first time. The radio counterpart to IGR J17091-3624 was detected during all four observations with the ATCA. In the hard state, the radio spectrum is typical of optically thick synchrotron emission from a self-absorbed compact jet. In the soft intermediate state, the detection of optically thin synchrotron emission is probably due to a discrete ejection event associated with the state transition. The position of IGR J17091-3624 in the radio versus X-ray luminosity diagram (aka fundamental plane) is compatible with that of the other black hole sources for distances greater than 11 kpc. IGR J17091-3624 also appears as a new member of the few sources that show a strong quenching of radio emission after the state transition. Using the estimated luminosity at the spectral transition from the hard state, and for a typical mass of 10 M_sun, we estimate a distance to the source between ~11 and ~17 kpc, compatible with the radio behaviour of the source.

description: Excerpts from the report: The Lower Rio Grande Valley of Texas consists of Willacy, Cameron, Hidalgo, and Starr Counties. The Valley is a major commercial fruit and vegetable producing area. This report is designed to determine the degree of pricing efficiency in the fresh tomato market of the Lower Rio Grande Valley. Pricing efficiency is described as the manner in which the market converts prices at the f.o.b. level to prices paid farmers. Briefly the methods used in this study consisted of (a) sampling a large number of actual sales transactions at the f.o.b. and farm level, (b) estimating the actual relation between f.o.b. prices and prices paid growers, and (c) determining whether factors such as changes in the percentage of all shipments in each grade explain variations in the shipping-point margin. The structure of the market was considered also, since market structure can influence competitive behavior and hence the nature of margins.

description: Context Solid-cystic pseudopapillary tumor of the pancreas is a rare tumor, but has favorable prognosis even in the presence of distant metastases. It is often associated with diagnostic and therapeutic challenges. Case reports Described are two cases of solid-cystic pseudopapillary tumor of the pancreas managed in our hospital between January 2000 and January 2010. One female and one male with mean age of 42 years (range: 33 to 51 years). Data collected were: presenting symptoms, signs, imaging and management. Literature review was obtained from computer generated MEDLINE and Google Scholar search for solid-cystic pseudopapillary tumor of the pancreas between 1980 and 2010. Articles relevant to the scope of this paper were selected. The incidence of solid-cystic pseudopapillary tumors of the pancreas in our institution is 2 cases in 10 years; i.e., 0.2 cases/year. Clinical presentation include; palpable abdominal mass, vague abdominal discomfort, increasing abdominal girth, significant weight loss, nausea and vomiting in both patients. The mean diameter of the tumors was 7.0 cm (range: 5.9 to 8.0 cm). Pancreaticoduodenectomy was performed on both patients. None received adjuvant therapy and no cancer recurrence was detected on follow-up. Conclusion Solid-cystic pseudopapillary tumor of the pancreas is a rare tumor with a favorable prognosis even with distant metastases; therefore, attempts must be made to differentiate it from other pancreatic neoplasms. Clinical and radiological studies alone are insufficient to establish the diagnosis of a pancreatic mass and tissue biopsy should be sought. Surgery is generally curative and should be pursued independent of size and distant metastases.

description: We show how intrinsic material properties modify light transmission through subwavelength hole arrays on thin metallic films in the THz regime. We compare the temperature-dependent transmittance of Au films and MgB$_{2}$ films. The experimental data is consistent with analytical calculations, and is attributed to the temperature change of the conductivity of both films. The transmission versus conductivity is interpreted within the open resonator model when taking the skin depth into consideration. We also show that the efficiency of this temperature control depends on the ratio of the transmission peak frequency to the superconducting energy gap in MgB$_{2}$ films.

description: Context Cystic lymphangioma of the pancreas presenting as acute abdomen in adults has not been reported before. Case report We report the case of a young man who presented with severe pain in the upper abdomen and abdominal swelling. On imaging, he was found to have a giant multiseptate cystic lesion occupying almost the entire abdomen anterior to the pancreas. On exploration, a cystic mass involving the head of the pancreas and densely adherent to the antrum, and the second and third parts of the duodenum was found and a classic Whipple pancreaticoduodenectomy was done. Histology revealed a diagnosis of cystic lymphangioma. Conclusion Cystic lymphangioma is a rare benign tumor of the pancreas and this is the first reported case in an adult presenting with acute abdomen. Though rarely diagnosed preoperatively, this entity should also be considered in the differential diagnosis of cystic lesions of the pancreas. Complete surgical excision is curative.

description: Context Colonic involvement is an uncommon but potentially lethal complication of severe acute pancreatitis and has received little attention in the surgical literature. Such complications can range from localized colonic pathology to widespread ischaemic pancolitis. Treatment options have historically been limited to resection of the affected segment. Case report We describe the successful role of video assisted retroperitoneal pancreatic debridement in the management of two cases presenting with major gastrointestinal haemorrhage due to localised colonic ulceration on the background of acute necrotising pancreatitis. Conclusion Video assisted retroperitoneal debridement should be considered early in the management of local colonic complications associated with severe acute necrotising pancreatitis.

description: Context A pancreatic pseudocyst is defined as a collection of pancreatic juice enclosed by a wall of fibrous or granulation tissue which is not lined by epithelium. Acute pseudocysts occur in acute pancreatitis but can be found after an acute exacerbation of chronic pancreatitis. Chronic pancreatic pseudocysts are typically found in chronic pancreatitis but may develop after an occurrence of acute pancreatitis as well. Most acute fluid collections and pseudocysts will show spontaneous resolution while the remaining may persist with or without symptoms, or progress to produce complications. Treatment is indicated for persistent, symptomatic pseudocysts and, in the case of complications. There is no clear consensus regarding the optimal clinical or radiologic follow-up after treatment. Detection of late recurrence is not common, and the possibility of a cystic neoplasm must be ruled out. Case report We report the case of a 67-year-old female patient who was referred to our institution as the result of a pancreatic pseudocyst. The patient had presented a pancreatic pseudocyst 9 years earlier which had been surgically treated by a cystogastrostomy. No additional acute pancreatic episodes occurred. The diagnostic and treatment approach of this unusual late recurrent pancreatic pseudocyst is herein described. Conclusion The unusual late presentation of a recurrent pancreatic pseudocyst requires clinical, laboratory and radiological evaluation. In the present case, the clinical background, amylase fluid levels and tomographic findings were highly suggestive of a pancreatic pseudocyst.

description: We present GALEX far-ultraviolet (FUV) and near-ultraviolet (NUV) as well as SDSS g, r, i photometry and structural parameters for the Herschel Reference Survey, a magnitude-, volume-limited sample of nearby galaxies in different environments. We use this unique dataset to investigate the ultraviolet (UV) structural scaling relations of nearby galaxies and to determine how the properties of the UV disk vary with atomic hydrogen content and environment. We find a clear change of slope in the stellar mass vs. effective surface brightness relation when moving from the optical to the UV, with more massive galaxies having brighter optical but fainter UV surface brightnesses than smaller systems. A similar change of slope is also seen in the radius vs. surface brightness relation. By comparing our observations with the predictions of a simple multi-zone chemical model of galaxy evolution, we show that these findings are a natural consequence of a much more efficient inside-out growth of the stellar disk in massive galaxies. We confirm that isophotal radii are always a better proxy for the size of the stellar/star-forming disk than effective quantities and we show that the extent of the UV disk (normalized to the optical size) is strongly correlated to the integrated HI gas fraction. This relation still holds even when cluster spirals are considered, with HI-deficient systems having less extended star-forming disks than HI-normal galaxies. Interestingly, the star formation in the inner part of HI-deficient galaxies is significantly less affected by the removal of the atomic hydrogen, as expected in a simple ram-pressure stripping scenario. These results suggest that it is the amount of HI that regulates the growth of the star-forming disk in the outskirts of galaxies.

description: A geometrical form of the supersymmetry conditions for D-branes on arbitrary type II supersymmetric backgrounds is derived, as well as the associated BPS bounds. The treatment is general and allows to consider, for instance, non-static configurations or D-branes supporting a non-vanishing electric flux, hence completing previous partial results. In particular, our discussion clarifies how the notion of calibration can be extended in order to be applicable to the most general supersymmetric configurations. As an exemplifying preliminary step, the procedure followed is first applied to fundamental strings.

description: Context Epidermoid cysts occurring within intrapancreatic accessory spleens are exceptionally rare entities, with only 21 previously reported cases. Their clinical presentation prior to pathologic assessment can raise concern for possible malignancy; however, they behave in a benign fashion. Case report A 62-year-old male presented with complaints of abdominal pain. Imaging revealed left-sided retroperitoneal mass and surgical exploration was recommended. Surgery revealed a cystic cavity containing necrotic debris originating from the tail of the pancreas. Microscopy was consistent with an epidermoid cyst arising within an intrapancreatic accessory spleen with positive immunoperoxidase staining for CEA. Conclusion Epidermoid cysts occurring within intrapancreatic accessory spleens can mimic a malignant process both clinically and radiographically. Surgery with pathologic assessment is the only reliable means of diagnosis. While they are a very rare entity, it is an important component of a complete differential diagnosis for a patient presenting with a pancreatic tail mass.

description: Excerpts from the report: The Lower Rio Grande Valley of Texas is a major commercial fruit and vegetable producing area made up of Willacy, Cameron, Hidalgo, and Starr Counties. This report discusses pricing efficiency of the market with respect to variations in quality of tomatoes. Pricing efficiency, as defined for this report, is the manner in which shippers adjust margins in response to changes in costs caused by quality variations. The shipping point margin is the difference between the weighted average price paid growers for tomatoes delivered to the packing shed "culls out" and the weighted average f.o.b. price of all tomatoes sold by the shippers.

description: Algebraic approach to quantum non - separability is applied to the case of two qubits. It is based on the partition of the algebra of observables into independent subalgebras and the tensor product structure of the Hilbert space is not exploited. Even in this simple case, such general formulation has some advantages. Using algebraic formalism we can explicitly show the relativity of the notion of entanglement to the observables measured in the system and characterize separable and non - separable pure states. As a universal measure of non - separability of pure states we propose to take so called total correlation. This quantity depends on the state as well as on the algebraic partition. Its numerical value is given by the norm of the corresponding correlation matrix

description: Intestinal ultrasound (IUS) performed by experts is a valuable tool for the diagnostic work-up and monitoring of Crohn’s disease (CD). However, concern about insufficient training and perceived high inter-observer variability limit the adoption of IUS in CD. We examined the diagnostic accuracy of trainee-performed IUS in patients with suspected CD. Patients recruited to a prospective trial investigating the diagnostic accuracy of magnetic resonance enterocolonography (MREC) in patients with clinically suspected CD underwent IUS performed by trainees. The primary end-point was IUS per-patient sensitivity and specificity for ileocolonic CD determined by ileocolonoscopy. 129 patients with clinically suspected CD and a complete IC and IUS were included in the analysis. IUS detected signs of CD in 49 cases (small bowel 31, colon 15, small bowel, and colon 3). The sensitivity and specificity for detection of ileocolonic CD by trainee performed IUS improved during the first to the second half of the study period from 57.1% (CI 34.0-78.2) to 73.1% (CI 52.2-88.4) and 76.5% (CI 58.8-89.3) to 89.7% (CI 72.6-97.8). The overall sensitivity and specificity of diagnosing CD with IUS were 65.4% (CI 50.9-78.0) and 80.5% (CI 69.9-88.7). There was no difference in diagnostic performance between IUS and MREC for the detection of CD. Trainees improved during the study, and IUS performance in disease detection corresponded to expert-evaluated MREC. Registered at ClinicalTrials.gov (NCT03134586).

description: This study challenges the current ‘utopian’ discourse in digital inclusion rhetoric by providing insights into the complexity of digital inclusion initiative provision as a multilevel phenomenon, against a backdrop of digitalisation and digital-by-default policy.The aim of this study is to investigate digital inclusion initiative provision in the context of UK rural communities. Underpinned by the philosophy of critical realism, the study employs an exploratory qualitative case study that provides a critical discussion of digital inclusion initiative provision and a granular analysis of the dynamics, processes, experiences, and behaviours of those involved in the phenomenon. More specifically the study explores digital inclusion initiative provision from a multilevel perspective, from digital inclusion stakeholders that operate nationally across the UK; intermediaries delivering digital inclusion training and support in three specific rural regions of the UK with populations at increased risk of digital exclusion; and individuals who have received digital inclusion support within those three specific rural locations.Data collection involved semi-structured interviews, focus groups, observations, complemented by a brief document review. Activity Theory was utilised as an analytical framework to provide guidance from data collection through to empirical data analysis to help investigate digital inclusion initiative provision as a multilevel phenomenon.Key findings reveal digital inclusion initiative provision is a complicated process that is fraught with challenges and contradictions, that hamper the realisation of the digital inclusion agenda. Digital inclusion training and support is provided to individuals from ‘all walks of life’, not just the digitally excluded, and not everyone has beneficial outcomes. Importantly, the study reveals the bridging role of human intermediation, and the need for rural communities to be considered in UK government digital policy.Contributions of this study include new insights into the understanding digital inclusion initiative provision and the inherent challenges in that process, the usefulness of Activity Theory to help unravel the complexity of digital inclusion initiatives as a multilevel phenomenon; and recommendations for change in the provision of digital inclusion initiatives that have implications for policy and practice.

description: We have performed a simulation study of 3D cohesionless granular flows down an inclined chute. We find that the oscillations observed in [L.E. Silbert, Phys. Rev. Lett., 94, 098002 (2005)] near the angle of repose are harmonic vibrations of the lowest normal mode. Their frequencies depend on the contact stiffness as well as on the depth of the flow. Could these oscillations account for the phenomena of "booming sand"? We estimate an effective contact stiffness from the Hertz law, but this leads to frequencies several times higher than observed. However, the Hertz law also predicts interpenetrations of a few nanometers, indicating that the oscillations frequencies are governed by the surface stiffness, which can be much lower than the bulk one. This is in agreement with previous studies ascribing the ability to sing to the presence of a soft coating on the grain surface.

description: Compactification of the heterotic string on toroidal orbifolds is a promising set-up for the construction of realistic unified models of particle physics. The target space dynamics of such models, however, drives them slightly away from the orbifold point in moduli space. This resolves curvature singularities, but makes the string computations very difficult. On these smooth manifolds we have to rely on an effective supergravity approximation in the large volume limit. By comparing an orbifold example with its blow-up version, we try to transfer the computational power of the orbifold to the smooth manifold. Using local properties, we establish a perfect map of the the chiral spectra as well as the (local) anomalies of these models. A key element in this discussion is the Green-Schwarz anomaly polynomial. It allows us to identify those redefinitions of chiral fields and localized axions in the blow-up process which are relevant for the interactions (such as Yukawa-couplings) in the model on the smooth space.

description: Color codes are a class of topological quantum codes with a high error threshold and large set of transversal encoded gates, and are thus suitable for fault tolerant quantum computation in two-dimensional architectures. Recently, computationally efficient decoders for the color codes were proposed. We describe an alternate efficient iterative decoder for topological color codes, and apply it to the color code on hexagonal lattice embedded on a torus. In numerical simulations, we find an error threshold of 7.8% for independent dephasing and spin flip errors.

description: Context Pancreatic extra-gastrointestinal stromal tumors are extremely uncommon neoplasm. To the best of our knowledge, only eleven cases have been reported in the literature. All the case reports published mostly involve diagnoses made on surgical pathology. Case report A 40-year-old male patient presented with asthenia, mild abdominal pain, severe anemia and weight loss. Contrast-enhanced computed tomography of the abdomen revealed a heterogeneously enhancing mass (6.5x6.0 cm) in the body and head of the pancreas. Ultrasound-guided fine needle aspiration (US-FNA) was performed on the mass of the pancreas before a pancreaticoduodenectomy. A cytological diagnosis of pancreatic malignant mesenchymal neoplasm was made. The final diagnosis of primary pancreatic extra-gastrointestinal stromal tumor was confirmed by histopathological examination and immunohistochemical findings (CD117 positivity). This case was diagnosed by percutaneous transabdominal ultrasound, rather than endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) which had been used in three previous cases. Conclusion We report a very unusual case of pancreatic extra-gastrointestinal stromal tumor which was diagnosed by US-FNA cytology. Although this is uncommon in the pancreas, extra-gastrointestinal stromal tumors should be considered in the differential diagnosis of solid and cystic pancreatic masses on cytology.

description: The 4/5-law of turbulence, which characterizes the energy cascade from large to small-sized eddies at high Reynolds numbers in classical fluids, is verified experimentally in a superfluid 4He wind tunnel, operated down to 1.56 K and up to R_lambda ~ 1640. The result is corroborated by high-resolution simulations of Landau-Tisza's two-fluid model down to 1.15 K, corresponding to a residual normal fluid concentration below 3 % but with a lower Reynolds number of order R_lambda ~ 100. Although the Kármán-Howarth equation (including a viscous term) is not valid \emph{a priori} in a superfluid, it is found that it provides an empirical description of the deviation from the ideal 4/5-law at small scales and allows us to identify an effective viscosity for the superfluid, whose value matches the kinematic viscosity of the normal fluid regardless of its concentration.

In this article, we examine the clinical course of these potentially fatal complications. Case reports Citing three clinical cases, we present the spectrum of splenic complications in pancreatitis and explore the anatomical causal relationships and pathological basis of such complications. A literature review was carried out to inform on the incidence, morbidity and mortality rates, and clinical course especially diagnostic and management options for these patients. The spectrum of splenic complications in pancreatitis is wide ranging from pseudo cysts to haematomas, haemorrhages, infarctions and life threatening splenic rupture. Although a contrast enhanced helical CT scan is the investigation of choice a high index of clinical suspicion is essential in their early identification. Splenic complications in pancreatitis incur a high morbidity (79%) and a significant mortality (8%). Conclusions Splenic parenchymal complications in pancreatitis are an increasingly recognised entity and should be suspected in patients with inflammation and or necrosis involving the tail of pancreas. Conservative management is feasible with close radiological monitoring for most patients in a tertiary referral centre with appropriate expertise and surgery may be reserved for haemodynamically unstable patients.

description: Excerpts from the report: This report discusses costs, efficiencies, and economies of scale in packing mature green tomatoes for fresh market in the Lower Rio Grande Valley of Texas. Packing costs are estimated for model plants of three capacities under assumed conditions of tomato quality, type of containers packed, and length of packing season. Variations in these items are also considered, and their influence on costs estimated. Finally, the efficient model plants developed are compared with existing plants, and suggestions are made for improvements in the operations of present plants. Efficiency in this study is measured by packing costs per unit volume--low unit costs represent high efficiency, and vice versa. No attempt is made to develop, or even suggest, new methods or equipment. The objective was the more modest one of estimating which combinations of present methods result in least cost.
Bulk emission by higher-dimensional black holes: almost perfect blackbody radiation

description: We study the Hawking radiation emitted into the bulk by $(D+1)$-dimensional Schwarzschild black holes. It is well-known that the black-hole spectrum departs from exact blackbody form due to the frequency dependence of the `greybody' factors. For intermediate values of $D$ ($3\leq D\lesssim10$), these frequency-dependent factors may significantly modify the spectrum of the emitted radiation. However, we point out that for $D\gg1$, the typical wavelengths in the black-hole spectrum are much {\it shorter} than the size of the black hole. In this regime, the greybody factors are well described by the geometric-optics approximation according to which they are almost frequency-independent. Following this observation, we argue that for higher-dimensional black holes with $D\gg1$, the total power emitted into the bulk should be well approximated by the analytical formula for perfect blackbody radiation. We test the validity of this analytical prediction with numerical computations.

description: Acute intestinal necrosis (AIN) is a disease with devastating high mortality. AIN due to obstructed arterial blood flow has a blurred clinical presentation. Timely diagnosis is paramount, and a blood-based biomarker is warranted to increase patient survival. We aimed to assess intestinal fatty acid binding protein (I-FABP) and endothelin-1 as diagnostic biomarkers for AIN. To our knowledge, this is the first study exploring endothelin-1 in AIN patients from a general surgical population. We conducted a single-centre nested case–control study comparing acutely admitted AIN patients to age- and sex-matched non-AIN patients during 2015–2016. I-FABP and endothelin-1 were analysed using an enzyme-linked immunosorbent assay. L-lactate levels were also measured in all patients. Cut-offs were estimated using receiver operator characteristic curves, and the diagnostic performance was estimated using the area under the receiver operator characteristic curve (AUC). We identified 43 AIN patients and included 225 matched control patients. Median levels of I-FABP, endothelin-1 and L-lactate were 3550 (IQR: 1746–9235) pg/ml, 3.91 (IQR: 3.33–5.19) pg/ml and 0.92 (IQR: 0.74–1.45) mM in AIN patients and 1731 (IQR: 1124–2848) pg/ml, 2.94 (IQR: 2.32–3.82) pg/ml and 0.85 (IQR: 0.64-1.21) mM in control patients, respectively. The diagnostic performances of endothelin-1 and of I-FABP + endothelin-1 combined were moderate. Endothelin-1 alone revealed an AUC of 0.74 (0.67; 0.82). The sensitivity and specificity of endothelin-1 were 0.81 and 0.64, respectively. I-FABP and endothelin-1 are promising biomarkers for AIN, with moderate diagnostic performance compared with the commonly used biomarker L-lactate. ClinicalTrials.gov: NCT05665946.

description: Context Acinar cell carcinoma is a rare pancreatic malignant tumor, which can be associated with a particular manifestation: pancreatic panniculitis. It presents with erythematous subcutaneous nodules located mainly on the legs. The skin lesions can precede, be concurrent with or follow the pancreatic illness. The pathogenesis is not fully understood, but it is believed to be associated with high levels of serum lipase produced by the neoplasm, causing fat necrosis in tissues. The treatment of pancreatic panniculitis is directed at the underlying pancreatic disease, which may result in regression of the skin lesions. We report a case of pancreatic acinar cell carcinoma associated with subcutaneous panniculitis together with a review of the English literature. Case report A 79-year-old woman, with a 13-month history of acute pancreatitis, asthenia, weight loss, and the CT finding of a mass in the pancreatic head, presented complaining of multiple, migrant and painful subcutaneous nodules on her lower extremities. High serum lipase levels were also present. She underwent a pancreaticoduodenectomy, with subsequent regression of the skin lesions and normalization of her serum lipase levels. Histology revealed an acinar cell carcinoma of the pancreas. Liver metastases occurred six months after surgery, and the patient underwent chemotherapy with gemcitabine. She is still alive 14 months after the initial surgery. Conclusions Although rare, the association between acinar cell carcinoma and pancreatic panniculitis has been described in the literature. In a patient with subcutaneous nodules, the presence of acinar cell carcinoma should be considered in order to prevent long delays in the diagnosis and treatment of this pancreatic malignancy.

description: The alternative dynamics of loop quantum cosmology is examined by the path integral formulation. We consider the spatially flat FRW models with a massless scalar field, where the alternative quantization inherit more features from full loop quantum gravity. The path integrals can be formulated in both timeless and deparameterized frameworks. It turns out that the effective Hamiltonians derived from the two different viewpoints are equivalent to each other. Moreover, the first-order modified Friedmann equations are derived and predict quantum bounces for contracting universe, which coincide with those obtained in canonical theory.

description: Autoimmune pancreatitis is the pancreatic manifestation of a novel clinicopathological disorder called systemic IgG4-related sclerosing disease. Beside the pancreas, this entity affects other sites (salivary glands, orbit, lung, thyroid, gallbladder, biliary tree system, kidney, abdominal aorta, retroperitoneum, prostate, and lymph node) by infiltration with IgG4-positive plasma cells. Several case reports and small case series have demonstrated the utility of integrated positron emission tomography/computed tomography (PET/CT) in monitoring therapy and documenting relapse and flare-up of autoimmune pancreatitis. However, there are no reports on the usefulness of PET/CT in selecting extrapancreatic sites for tissue sampling. We herein demonstrate the clinical utility of integrated PET/CT in 3 cases of systemic IgG4-related sclerosing disease for targeting extrapancreatic biopsy sites.

description: Excerpts from the report: This report examines market structure and prices in the fresh citrus market of the Lower Rio Grande Valley. The primary aspect of pricing considered is the pricing efficiency of the market--the manner in which the market transmits prices from the f.o.b. to the grower level. Data on number and size of firms in the Lower Valley were obtained from the offices of the Texas Valley Citrus Committee. Information on citrus purchases and sales at shipping point was obtained from a sample of 14 shipping firms handling about 78 percent of all fresh citrus shipped during the 1960-61 season.
Surface free energies for nematic shells

description: We propose a continuum model to describe the molecular alignment in thin nematic shells. By contrast with previous accounts, the two-dimensional free energy, aimed at describing the physics of thin films of nematics deposited on curved substrates, is not postulated but it is deduced from the conventional three-dimensional theories of nematic liquid crystals. Both the director and the order-tensor theories are taken into account. The so-obtained surface energies exhibit extra terms compared to earlier models. These terms reflect the coupling of the geometry of the shell with the nematic order parameters. As expected, the shape of the shell plays a key role in the equilibrium configurations of nematics coating it.

description: Pancreatic cancer is known to metastasize rapidly. Liver and peritoneum are the most common sites of metastases in pancreatic cancer, followed by lungs, bones and brain. Less common sites of metastases such as muscle, skin, heart, pleura, stomach, umbilicus, kidney, appendix, spermatic cord and prostate have also been reported in pancreatic cancer. Cutaneous metastasis mostly occurs around umbilicus. A site other than umbilicus is rarely reported. The authors report a case of multiple skin metastases in a patient with primary pancreatic cancer and review the literature.

description: We discuss radiation reaction effects on charges propagating in ultra-intense laser fields. Our analysis is based on an analytic solution of the Landau-Lifshitz equation. We suggest to measure radiation reaction in terms of a symmetry breaking parameter associated with the violation of null translation invariance in the direction opposite to the laser beam. As the Landau-Lifshitz equation is nonlinear the energy transfer within the pulse is rather sensitive to initial conditions. This is elucidated by comparing colliding and fixed target modes in electron laser collisions.
