description: INTRODUCTION: Aortoiliac occlusive disease (AIOD) can be treated using either open surgical revascularization (OSR) or endovascular revascularization (ER). METHODS: A Medline search was performed in order to identify articles focused on the treatment of aortoiliac occlusive disease. Additional articles of scientific interest for the purpose of this non-systematic review were included by cross-referencing. RESULTS: There are a few articles reporting direct results between both techniques based on retrospective or prospective single center or multicenter studies. In the majority of studies, primary patency is generally better for surgery in comparison to ER, but at a cost of more postoperative complications, with higher rates of respiratory failure and wound infection in the open group. On the other hand, endovascular recanalization is related to higher rates of limb ischemia/thrombosis, renal dysfunction and reinterventions. In the presence of femoral artery calcified disease, the hybrid approach should be considered. CONCLUSIONS: Endovascular treatment is a suitable alternative for extensive AIOD and can be accomplished in a less invasive manner, with most midterm outcomes comparable with open reconstruction. Surgery should be reserved for multilevel calcified disease and after endovascular failure.

description: INTRODUCTION: Stylocarotid syndrome is caused by the conflict between the styloid process and the vascular structures leading to carotid artery dissection (CAD) or compression. Being headache the most common initial symptom in patients with spontaneous CAD, eagle syndrome could be one explanation for some so-called spontaneous dissections since this symptom is also common in this syndrome. METHODS: Afrer analyzing the reported cases on Pubmed and Embase databases we divided the cases in compression and CAD groups ending up with completely different groups in terms of clinical presentation, management and follow-up. RESULTS: While management of compression group seems quite straightforward, the same is not true when CAD is present. Whether delayed styloidectomy after medical management plays a role in CAD, as it does for the compression group, is something to investigate.

description: INTRODUCTION: The ischemic window of kidney parenchyma is narrow, so a rapid development of renal infarction after acute renal artery occlusion is expected. However, patients often present with nonspecific symptoms and laboratory findings, making the early diagnosis challenging and contributing to treatment delay. Irreversible kidney dysfunction seems not to depend on the total warm ischemia time alone, and other factors could play a role. CASE REPORT: A 64-year-old male with chronic kidney disease presented to the emergency department with acute kidney injury of unknown etiology. Unfavorable evolution demanded the initiation of hemodialysis due to ref ractory hypervolemia and resistant high blood pressure some days later. A computed tomography angiography showed aortoiliac occlusion starting below the superior mesenteric artery, conditioning the occlusion of the proximal segment of both renal arteries. A splenorenal retrocaval bypass was done uneventfully, 21 days after the initial presentation, to revascularize the right kidney. After surgery, the patient showed marked improvement of diuresis with decreased nitrogen retention parameters, allowing definitive suspension of the dialysis technique in the first post-operative week and controlled blood pressure. Serum creatinine dropped to baseline and remained stable at one year of follow-up. Chronic limb-threatening ischemia developed later in the left lower limb, and the patient was revascularized with an axillobifemoral bypass. CONCLUSION: Our case highlights the benefit of aggressive late renal revascularization in selected patients with acute renal artery occlusion who maintain residual tubular function and some perfusion of kidneys despite proximal occlusion of the renal artery. More extensive studies would be essential to provide adequate patient selection and management recommendations.

description: INTRODUCTION: The concept of the Nellix endoprosthesis is based on endovascular aneurysm sealing with endobags and was launched in the market for endovascular abdominal aortic aneurysm repair (EVAR). The manufacturer recently issued a hazard alert due to higher rates of endoleaks, migration and aneurysm enlargement. CASE REPORT: The authors present a clinical case of a seventy year-old man previously submitted to EVAR with a Nellix device in another country. The patient presented with an asymptomatic Type Ia endoleak and proximal aortic neck aneurysmatic degeneration. The anatomy was considered unfavourable for further endovascular management. After multidisciplinary discussion and workup, open surgical conversion was selected. Complete endoprosthesis explantation and in-situ reconstruction were performed. The post-operative course was uneventful. CONCLUSION: Once presented with a patient considered fit for open surgical conversion and with aneurysm morphology unfavourable for endovascular, the authors believe that open conversion may constitute a very acceptable method of repair and should be offered.

description: We report results of 27Al-NMR measurements on a single crystal of PrTi2Al20, in which the ground state of Pr3+ ions in the crystalline electric field is the nonmagnetic Gamma3 doublet. From the analysis of NMR spectra with the magnetic field applied precisely along the <111> and <100> directions, we determined the electric field gradient tensors for all three inequivalent Al sites (Al(1) ~ Al(3) sites) and the anisotropic Knight shifts for the Al(3) sites. The hyperfine coupling tensor at the Al(3) sites is strongly anisotropic and much larger than the classical dipolar coupling, indication importance of the anisotropic hybridization between the conduction and f electron states.

description: In this paper, we study the formation and early evolution of a limb coronal mass ejection (CME) and its associated shock wave that occurred on 2014 January 8. The extreme ultraviolet (EUV) images provided by the Atmospheric Imaging Assembly (AIA) on board \textit{Solar Dynamics Observatory} disclose that the CME first appears as a bubble-like structure. Subsequently, its expansion forms the CME and causes a quasi-circular EUV wave. Interestingly, both the CME and the wave front are clearly visible at all of the AIA EUV passbands. Through a detailed kinematical analysis, it is found that the expansion of the CME undergoes two phases: a first phase with a strong but transient lateral over-expansion followed by a second phase with a self-similar expansion. The temporal evolution of the expansion velocity coincides very well with the variation of the 25--50 keV hard X-ray flux of the associated flare, which indicates that magnetic reconnection most likely plays an important role in driving the expansion. Moreover, we find that, when the velocity of the CME reaches $\sim$600 km s$^{-1}$, the EUV wave starts to evolve into a shock wave, which is evidenced by the appearance of a type II radio burst. The shock's formation height is estimated to be $\sim$0.2$R_{sun}$, which is much lower than the height derived previously. Finally, we also study the thermal properties of the CME and the EUV wave. We find that the plasma in the CME leading front and the wave front has a temperature of $\sim$2 MK, while that in the CME core region and the flare region has a much higher temperature of $\ge$8 MK.

description: Strong spectral softening has been revealed in the late X-ray afterglows of some gamma-ray bursts (GRBs). The scenario of X-ray scattering around circum-burst dusty medium has been supported by previous works due to its overall successful prediction of both the temporal and spectral evolution of some X-ray afterglows. To further investigate the observed feature of spectral softening, we now systematically search the X-ray afterglows detected by X-Ray Telescope (XRT) of Swift and collect twelve GRBs with significant late-time spectral softening. We find that dust scattering could be the dominant radiative mechanism for these X-ray afterglows regarding their temporal and spectral features. For some well observed bursts with high-quality data, their time-resolved spectra could be well produced within the scattering scenario by taking into account the X-ray absorption from circum-burst medium. We also find that during spectral softening the power-law index in the high energy end of the spectra does not vary much. The spectral softening is mainly manifested by the spectral peak energy continually moving to the soft end.

description: OBJECTIVE: Venous stenting of iliocaval obstructions has become a more frequent procedure over the last two decades. In-stent stenosis and thrombosis are potential complications, causing one of the main causes of symptoms recurrence and impacting quality of life. The aim of this review is to report on the impact of venous stent patency loss, as well on risk factors and management. METHODS: A systematic review was conducted according to the recommendations of the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement. RESULTS: After a literature search, 12 studies (two prospective and 10 retrospective studies) were included in the analysis. A total of 1981 patients (34.1% male) and 2388 limbs (63.6% left side) were assessed. Mean age was 43.5 years (range 16-99). Indication for stenting included deep venous thrombosis (DVT) (4%), post-thrombotic syndrome (PTS) (18.8%) and non-thrombotic iliac vein lesions (NIVLs) (77.2%). Regarding treatment, most patients were submitted to angioplasty and stenting only (87%). Associated catheter directed thrombolysis or mechanical thrombectomy was performed when indicated (8.4%), and in the remaining an AVF/endophlebetomy was performed (4.6%). Primary, primary assisted and secondary patency rates at one year ranged from 68-100%, 79-90% and 85.8-100%, respectively. Reported anticoagulation duration after stenting ranged from 1-12 months. In one study involving only patients treated for NIVLs, no anticoagulation was prescribed, and antithrombotic therapy was continued for three months. Follow-up strategies included clinical and imagiological control with a mean follow-up of 19.7 months. Post-procedural stent re-stenosis was reported in 121 limbs (5.1%) and stent occlusion in 81 limbs (3.4%); the latter was distributed as follows: 11.1% after DVT, 77.8% PTS and 11.1% NIVLs. A total of 186 re-interventions were performed in symptomatic patients. The prognostic factor most consistently associated with stent failure was thrombotic inflow veins. Other reported factors were incomplete thrombolysis and age younger than 40 years. Stent placement below the inguinal ligament, type of stent and anticoagulation regimen do not seem to affect stent patency. CONCLUSION: Regarding venous lesions of the lower limbs, a selective approach and planning should focus on identification of risk factors for stent failure. It is noteworthy that most stent occlusions occur in post-thrombotic limbs. Stent failure continued after 6 months, emphasizing the importance of an extended surveillance especially on these patients.

description: Fission-fragment mass distributions were measured for 225,227Pa nuclei formed in fusion reactions of 19F + 206, 208Pb around fusion barrier energies. Mass-angle correlations do not indicate any quasi-fission like events in this bombarding energy range. Mass distributions were fitted by Gaussian distribution and mass variance extracted. At below-barrier energies, the mass variance was found to increase with decrease in energy for both nuclei. Results from present work were compared with existing data for induced fission of 224, 226Th and 228U around barrier energies. Enhancement in mass variance of 225, 227Pa nuclei at below-barrier energies shows evidence for presence of asymmetric fission events mixed with symmetric fission events. This is in agreement with the results of mass distributions of nearby nuclei 224, 226Th and 228U where two-mode fission process was observed. Two-mode feature of fission arises due to the shell effects changing the landscape of the potential energy surfaces at low excitation energies. The excitation-energy dependence of the mass variance gives strong evidence for survival of microscopic shell effects in fission of light actinide nuclei 225, 227Pa with initial excitation energy ~30 - 50 MeV.

description: Multiferroic properties of orthorhombic HoMnO3 (Pbnm space group) are significantly modified by epitaxial compressive strain along the a-axis. We are able to focus on the effect of strain solely along the a-axis by using an YAlO3 (010) substrate, which has only a small lattice mismatch with HoMnO3 along the other in-plane direction (the c-axis). Multiferroic properties of strained and relaxed HoMnO3 thin films are compared with those reported for bulk, and are found to differ widely. A relaxed film exhibits bulk-like properties such as a ferroelectric transition temperature of 25 K and an incommensurate antiferromagnetic order below 39 K, with an ordering wave vector of (0 qb 0) with qb ~ 0.41 at 10 K. A strained film becomes ferroelectric already at 37.5 K and has an incommensurate magnetic order with qb ~ 0.49 at 10 K.

description: Atomically thin boron nitride (BN) is an important two-dimensional (2D) nanomaterial, with many properties distinct from graphene. In this feature article, these unique properties and associated applications often not possible from graphene are outlined. The article starts with characterization and identification of atomically thin BN. It is followed by demonstrating their strong oxidation resistance at high temperatures and applications in protecting metals from oxidation and corrosion. As flat insulators, BN nanosheets are ideal dielectric substrates for surface enhanced Raman spectroscopy (SERS) and electronic devices based on 2D heterostructures. The light emission of BN nanosheets in the deep ultraviolet (DUV) and ultraviolet (UV) regions are also included for its scientific and technological importance. The last part is dedicated to synthesis, characterization, and optical properties of BN nanoribbons, a special form of nanosheets.

description: INTRODUCTION: Light induced amaurosis refers to a transient monocular or binocular vision loss triggered by bright lights. Like amaurosis fugax, light induced amaurosis is associated with carotid artery stenosis but they differ from each other in presentation and pathophysiology. It is thought to be an impairment in the regeneration of retinal visual pigments caused by the inability of carotid circulation to sustain the increased metabolic activity occurring when the retina is exposed to bright lights. With this report we aim to present a case of light induced amaurosis and its management. CASE REPORT: We describe a 74-year-old man with the isolated complaint of monocular visual loss from his left eye when exposed to bright lights. These episodes were self-limited and lasted for several minutes. His vision was reportedly good between episodes. He also complained of headache and dizziness. There were no other focal neurological deficits present. The patient had a history of peripheral artery disease, chronic heart failure, hypertension, dyslipidaemia, permanent atrial fibrillation and had a history of heavy smoking in the past. Chronic medical therapy included anticoagulation with rivaroxaban, antiplatelet therapy with acetylsalicylic acid and atorvastatin. Imaging studies (doppler ultrasonography and Computed tomography angiography) revealed a significant morphologic stenosis of the left common carotid artery, left internal carotid artery with sub occlusive disease and right internal carotid artery with 70-75% stenosis (North American Symptomatic Carotid Endarterectomy Trial - NASCET). The vertebral arteries study did not reveal significant morphologic disease. The patient was submitted to left common and internal carotid artery endarterectomy and Dacron patch angioplasty. The visual symptoms progressively improved after surgical treatment. The dizziness and headache were completely gone. CONCLUSION: Light induced amaurosis is a rare and less known symptom associated with severe carotid artery stenosis. Its timely recognition is important to not deprive patients of timely treatment.

description: The insulating state of matter can be probed by means of a ground state geometrical marker, which is closely related to the modern theory of polarization (based on a Berry phase). In the present work we show that this marker can be applied to determine the metal-insulator transition in disordered systems. In particular, for non-interacting systems the geometrical marker can be obtained from the configurational average of the norm-squared one-body density matrix, which can be calculated within open as well as periodic boundary conditions. This is in sharp contrast to a classification based on the static conductivity, which is only sensible within periodic boundary conditions. We exemplify the method by considering a simple lattice model, known to have a metal-insulator transition as a function of the disorder strength and demonstrate that the transition point can be obtained accurately from the one-body density matrix. The approach has a general {\it ab-initio} formulation and can be applied to realistic disordered materials by standard electronic structure methods.

description: Metabolites produced via traditional biochemical processes affect intracellular communication, inflammation, and malignancy. Unexpectedly, acetyl-CoA, α-ketoglutarate and palmitic acid, which are chemical species of reactions catalyzed by highly abundant, gigantic enzymatic complexes, dubbed as “metabolons”, have broad “nonmetabolic” signaling functions. Conserved unstructured regions within metabolons determine the yield of these metabolites. Unstructured regions tether functional protein domains, act as spatial constraints to confine constituent enzyme communication, and, in the case of acetyl-CoA production, tend to be regulated by intricate phosphorylation patterns. This review presents the multifaceted roles of these three significant metabolites and describes how their perturbation leads to altered or transformed cellular function. Their dedicated enzymatic systems are then introduced, namely, the pyruvate dehydrogenase (PDH) and oxoglutarate dehydrogenase (OGDH) complexes, and the fatty acid synthase (FAS), with a particular focus on their structural characterization and the localization of unstructured regions. Finally, upstream metabolite regulation, in which spatial occupancy of unstructured regions within dedicated metabolons may affect metabolite availability and subsequently alter cell functions, is discussed.

description: INTRODUCTION: Renal cell carcinoma (RCC) frequently progress to involve the inferior vena cava (IVC) and even the right atrium (RA). Nephrectomy and eradication of the tumour thrombus, can extend survival and prevent symptoms of venous congestion. The authors evaluated the institutional experience of a tertiary center in the surgical management of RCC patients with tumour thrombi invading the IVC. METHODS: Retrospective analysis of a single-center consecutive serie of patients with RCC and IVC tumor thrombi treated with surgery in our department between 2012 and 2021 was carried out. Demographic data, diagnostic and procedural characteristics, clinical outcomes and survival analysis were examined. RESULTS: Of the included 18 patients, 33% (n=6) had smoking history, 78% (n=14) hypertension, 33% (n=6) diabetes and dyslipidaemia. Mean tumour size was 8.78±2.47cm (3-12cm), and 67% (n=12) of the cases were renal clear cell adenocarcinoma. On the basis of the Neves classification for IVC thrombus extension, 39% (n=7) of the patients had level I; 28% (n=5) level II; 17% (n=3) level III and 17% (n=3) level IV. The majority underwent radical nephrectomy, with cavotomy and vena cava thrombus removal followed by lateral venorrhaphy of the vena cava (89%,n=16). In one patient an infra-renal IVC ligation was performed and, in another patient, an IVC interposition with PTFE and a protesic-renal bypass were performed. In level IV, combined open sternotomy and cardiac bypass for RA thrombus control were necessary. Mean total operative time was 3h4min±1h19min and median intraoperative blood loss was 600ml requiring a median blood cells transfusion of 3.5units (0,16) during the hospital stay. Median ICU days was 2 days (0,14) and median hospital stay was 8 days (4,61). The mean preoperative serum creatinine was 1.23+0.38 mg/dL. After surgery, there was a mean decrease of serum creatinine of 0.001 mg/dL (p=.991) (paired T test), confirming the absence of renal impairment. Only one patient required reintervention in the post-operative course for splenectomy. Post- operative complications included one case of pulmonary embolism, pneumonia, acute coronary syndrome and two cases of temporary acute renal lesion. There was no 30-day mortality. Five patients underwent adjuvant chemotherapy. Median follow-up time was 19.5 months (6-46.2 months). The four-year overall survival rate was of 52.4% (figure 1). CONCLUSION: For advanced RCC with tumour thrombus extension into the IVC, despite the expected poor prognosis, nephrectomy and eradication of the entire tumour thrombus, has low morbidity and can prolong patient survival, in line with the presented results.

description: Two recently discovered very luminous supernovae (SNe) present stimulating cases to explore the extents of the available theoretical models. SN 2011kl represents the first detection of a supernova explosion associated with an ultra-long duration gamma ray burst. ASASSN-15lh was even claimed as the most luminous SN ever discovered, challenging the scenarios so far proposed for stellar explosions. Here we use our radiation hydrodynamics code in order to simulate magnetar powered SNe. To avoid explicitly assuming neutron star properties we adopt the magnetar luminosity and spin-down timescale as free parameters of the model. We find that the light curve (LC) of SN 2011kl is consistent with a magnetar power source, as previously proposed, but we note that some amount of 56^Ni (> 0.08 M_sun) is necessary to explain the low contrast between the LC peak and tail. For the case of ASASSN-15lh we find physically plausible magnetar parameters that reproduce the overall shape of the LC provided the progenitor mass is relatively large (a mass of the ejecta approx 6 M_sun). The ejecta hydrodynamics of this event is dominated by the magnetar input, while the effect is more moderate for SN 2011kl. We conclude that a magnetar model may be used for the interpretation of these events and that the hydrodynamic modeling is necessary to derive the properties of powerful magnetars and their progenitors.

description: Graph model is emerging as a very effective tool for learning the complex structures and relationships hidden in data. Generally, the critical purpose of graph-oriented learning algorithms is to construct an informative graph for image clustering and classification tasks. In addition to the classical $K$-nearest-neighbor and $r$-neighborhood methods for graph construction, $l_1$-graph and its variants are emerging methods for finding the neighboring samples of a center datum, where the corresponding ingoing edge weights are simultaneously derived by the sparse reconstruction coefficients of the remaining samples. However, the pair-wise links of $l_1$-graph are not capable of capturing the high order relationships between the center datum and its prominent data in sparse reconstruction. Meanwhile, from the perspective of variable selection, the $l_1$ norm sparse constraint, regarded as a LASSO model, tends to select only one datum from a group of data that are highly correlated and ignore the others. To simultaneously cope with these drawbacks, we propose a new elastic net hypergraph learning model, which consists of two steps. In the first step, the Robust Matrix Elastic Net model is constructed to find the canonically related samples in a somewhat greedy way, achieving the grouping effect by adding the $l_2$ penalty to the $l_1$ constraint. In the second step, hypergraph is used to represent the high order relationships between each datum and its prominent samples by regarding them as a hyperedge. Subsequently, hypergraph Laplacian matrix is constructed for further analysis. New hypergraph learning algorithms, including unsupervised clustering and multi-class semi-supervised classification, are then derived. Extensive experiments on face and handwriting databases demonstrate the effectiveness of the proposed method.

description: Regular vine copulas can describe a wider array of dependency patterns than the multivariate Gaussian copula or the multivariate Student's t copula. This paper presents two contributions related to model selection of regular vine copulas. First, our pair copula family selection procedure extends existing Bayesian family selection methods by allowing pair families to be chosen from an arbitrary set of candidate families. Second, our method represents the first Bayesian model selection approach to include the regular vine density construction in its scope of inference. The merits of our approach are established in a simulation study that benchmarks against methods suggested in current literature. A real data example about forecasting of portfolio asset returns for risk measurement and investment allocation illustrates the viability and relevance of the proposed scheme.

description: We study the generalization of the Kerr-Newmann black hole in 5D Einstein-Maxwell-Chern-Simons theory with free Chern-Simons coupling parameter. These black holes possess equal magnitude angular momenta and an event horizon of spherical topology. We focus on the extremal case with zero temperature. We find that, when the Chern-Simons coupling is greater than two times the supergravity case, new branches of black holes are found which violate uniqueness. In particular, a sequence of these black holes are non-static radially excited solutions with vanishing angular momentum. They approach the Reissner-Nordström solution as the excitation level increases.

description: Background: The rising availability of assemblies of large genomes (e.g. bread and durum wheat, barley) and their annotations deliver the basis to graphically present genome organization of parents and progenies on a physical scale. Genetic maps are a very important tool for breeders but often represent distorted models of the actual chromosomes, e.g., in centromeric and telomeric regions. This biased picture might lead to imprecise assumptions and estimations about the size and complexity of genetic regions and the selection of suitable molecular markers for the incorporation of traits in breeding populations or near-isogenic lines (NILs). Some software packages allow the graphical illustration of genotypic data, but to the best of our knowledge, suitable software packages that allow the comparison of genotypic data on the physical and genetic scale are currently unavailable. Results: We developed a simple Java-based-software called GenoTypeMapper (GTM) for comparing genotypic data on genetic and physical maps and tested it for effectiveness on data of two NILs that carry QTL-regions for drought stress tolerance from wild emmer on chromosome 2BS and 7AS. Both NILs were more tolerant to drought stress than their recurrent parents but exhibited additional undesirable traits such as delayed heading time. Conclusions: In this article, we illustrate that the software easily allows users to display and identify additional chromosomal introgressions in both NILs originating from the wild emmer parent. The ability to detect and diminish linkage drag can be of particular interest for pre-breeding purposes and the developed software is a well-suited tool in this respect. The software is based on a simple allele-matching algorithm between the offspring and parents of a crossing scheme. Despite this simple approach, GTM seems to be the only software that allows us to analyse, illustrate and compare genotypic data of offspring of different crossing schemes with up to four parents in two different maps. So far, up to 500 individuals with a maximum number of 50,000 markers can be examined with the software. The main limitation that hampers the performance of the software is the number of markers that are examined in parallel. Since each individual must be analysed separately, a maximum of ten individuals can currently be displayed in a single run. On a computer with an Intel five processor of the 8th generation, GTM can reliably either analyse a single individual with up to 12,000 markers or ten individuals with up to 3,600 markers in less than five seconds. Future work aims to improve the performance of the software so that more complex crossing schemes with more parents and more markers can be analysed.

description: The central regions of galaxies show the presence of super massive black holes and/or very dense stellar clusters. Both such objects seem to follow similar host-galaxy correlations, suggesting that they are members of the same family of Compact Massive Objects. Here we investigate a huge data collection of Compact Massive Objects properties to correlate them with absolute magnitude, velocity dispersion and mass of their host galaxies. We draw also some preliminary astrophysical conclusions.

Tracing the Milky Way Nuclear Wind with 21cm Atomic Hydrogen Emission

description: There is evidence in 21cm HI emission for voids several kpc in size centered approximately on the Galactic centre, both above and below the Galactic plane. These appear to map the boundaries of the Galactic nuclear wind. An analysis of HI at the tangent points, where the distance to the gas can be estimated with reasonable accuracy, shows a sharp transition at Galactic radii $R\lesssim 2.4$ kpc from the extended neutral gas layer characteristic of much of the Galactic disk, to a thin Gaussian layer with FWHM $\sim 125$ pc. An anti-correlation between HI and $γ$-ray emission at latitudes $10^{\circ} \leq |b| \leq 20^{\circ}$ suggests that the boundary of the extended HI layer marks the walls of the Fermi Bubbles. With HI we are able to trace the edges of the voids from $|z| > 2$ kpc down to $z\approx0$, where they have a radius $\sim 2$ kpc. The extended HI layer likely results from star formation in the disk, which is limited largely to $R \gtrsim 3$ kpc, so the wind may be expanding into an area of relatively little HI. Because the HI kinematics can discriminate between gas in the Galactic center and foreground material, 21cm HI emission may be the best probe of the extent of the nuclear wind near the Galactic plane.

description: The energy range of our earlier measured activation cross-sections data of longer-lived products of deuteron induced nuclear reactions on indium were extended from 40 MeV up to 50 MeV. The traditional stacked foil irradiation technique and non-destructive gamma spectrometry were used. No experimental data were found in literature for this higher energy range. Experimental cross-sections for the formation of the radionuclides $^{113,110}$Sn, $^{116m,115m,114m,113m,111,110g,109}$In and $^{115}$Cd are reported in the 37-50 MeV energy range, for production of $^{110}$Sn and $^{110g,109}$In these are the first measurements ever. The experimental data were compared with the results of cross section calculations of the ALICE and EMPIRE nuclear model codes and of the TALYS1.6 nuclear model code as listed in the on-line library TENDL-2014.
