Abstract
The study of high-velocity particle-laden flow interactions is of importance for the understanding of a wide range of natural phenomena, ranging from planetary formation to cloud interactions. Experimental observations of particle dynamics are sparse given the difficulty of generating high-velocity flows of many particles. Ejecta microjets are micron-scale jets formed by strong shocks interacting with imprinted surfaces to generate particle plumes traveling at several kilometers per second. As such, the interaction of two ejecta microjets provides a novel experimental methodology to study interacting particle streams. In this Letter, we report the first time sequences of x-ray radiography images of two interacting tin ejecta microjets taken on a platform designed for the OMEGA Extended Performance (OMEGA EP) laser. We observe that the microjets pass through each other unattenuated for the case of 11.7±3.2 GPa shock pressures and jet velocities of 2.2±0.5 km/s but show strong interaction dynamics for 116.0±6.1 GPa shock pressures and jet velocities of 6.5±0.5 km/s. We find that radiation-hydrodynamic simulations of the experiments are able to capture many aspects of the collisional behavior, such as the attenuation of jet velocity in the direction of propagation, but are unable to match the full spread of the strongly interacting cloud.

Abstract
Abstract
The objective of this study was to evaluate the effect of sire line on wean-to-finish performance, carcass characteristics, and meat pricing variables. Pigs used for this study were the progeny of a commercial Landrace x Large White female mated to one of the following sire lines: a purebred Duroc line (Line S1), or a synthetic (Line S2) or purebred Duroc line (Line S3) originating from a different genetic source. An equivalent number of pigs (n =144) were used per group, for 432 pigs placed on test. Average initial weights per line were 6.67 ± 0.24, 6.67 ± 0.24, and 6.60 ± 0.24 for lines S1, S2, and S3, respectively. At placement, 8 pigs were assigned to each pen (split sex) and blocked by line and initial BW, with 18 replicates per line. Data were analyzed at the pen level using the PROC MIXED procedure of SAS, where the effects of line, sex, and line*sex were fitted as fixed effects and replicate was fitted as a random effect. Overall, piglets from line S2 (0.403 vs 0.381; P ≤ 0.0004) and line S3 (0.402 vs 0.381; P ≤ 0.001) had improved GF compared with piglets from line S1. The ADFI was greater in piglets from line S1 relative to piglets from line S2 (2.264 vs 2.117 kg; P ≤ 0.0001) and line S3 (2.264 vs 2.159 kg; P ≤ 0.004). The ADG, HCW, dressing yield, and loin depth were not different among treatment (P > 1.00). Piglets from line S3 had greater percent lean (57.12 vs 56.29 %; P ≤ 0.0001) and better carcass grade premium ($7.07 vs 6.60; P ≤ 0.0291) relative to piglets from line S1. In conclusion, line S1 piglets had greatest ADFI, but line S2 pigs and line S3 piglets had better feed efficiency. Line S3 pigs were leaner and had better carcass grade premium.

Abstract
The objective of this study was to estimate the effect of sire line on sow and piglet performance during lactation. Commercial Landrace x Large White females (n = 60) were bred to one of the following sire lines: a purebred Duroc line (Line S1), a synthetic (Line S2), or purebred Duroc (Line S3) from a different genetic source. Matings were balanced by line and parity. Females were fed a common gestation and lactation diet during these respective phases. Sow and piglet data were analyzed as a completely randomized design using the GLM procedure of SAS. Results show that, during lactation, females bred to line S3 lost significantly (P = 0.01) more BW (-16.93 ± 3.56 kg) than females bred to line S2 (-2.00 ± 3.50 kg). However, no evidence of a difference (P = 0.18) in BW loss was detected between females bred to line S3 (-16.93 ± 3.56 kg) vs. Line S1 (-7.90 ± 3.56 kg). Further, sows bred to line S3 weaned significantly (P = 0.03) more piglets (12.0 ± 0.28) than females bred to line S2 (10.9 ± 0.27), but not (P = 0.1) compared to females bred to line S1 (11.7 ± 0.27). No significant effect of line (P > 0.05) or parity (P > 0.05) on total number of piglet’s born, number born alive, number of stillborn piglets, or preweaning mortality was detected. The number of mummified fetus tended to be lower in line S2 (0.17 vs 0.66; P = 0.079) and line S3 (0.12 vs 0.66; P = 0.051) sows compared with line S1 sows, respectively. In conclusion, sire line did not have a significant effect on total number born, number born alive, number stillborn, or preweaning mortality. However, females bred to line S3 lost significantly more BW during lact but weaned significantly more piglets than females bred to line S2.

Abstract
We present molecular dynamics simulations of shock and release in micron-scale tantalum crystals that exhibit postbreakout temperatures far exceeding those expected under the standard assumption of isentropic release. We show via an energy-budget analysis that this is due to plastic-work heating from material strength that largely counters thermoelastic cooling. The simulations are corroborated by experiments where the release temperatures of laser-shocked tantalum foils are deduced from their thermal strains via in situ x-ray diffraction and are found to be close to those behind the shock.

Abstract
1D spectral imaging was used to characterize the K-shell emission of Z ≈ 30-35 and Z ≈ 40-42 laser-irradiated foils at the National Ignition Facility. Foils were driven with up to 60 kJ of 3ω light, reaching laser irradiances on target between 0.5 and 20 × 10(15) W/cm(2). Laser-to-X-ray conversion efficiency (CE) into the Heα line (plus satellite emission) of 1.0%-1.5% and 0.15%-0.2% was measured for Z ≈ 30-32 and Z ≈ 40-42, respectively. Measured CE into Heα (plus satellite emission) of Br (Z = 35) compound foils (either KBr or RbBr) ranged between 0.16% and 0.29%. Measured spectra are compared with 1D non-local thermodynamic equilibrium atomic kinetic and radiation transport simulations, providing a fast and accurate predictive capability.

Abstract
Motion is a crucial source of information for a variety of tasks in social interactions. The process of how humans recognize complex articulated movements such as gestures or face expressions remains largely unclear. There is an ongoing discussion if and how explicit low-level motion information, such as optical flow, is involved in the recognition process. Motivated by this discussion, we introduce a computational model that classifies the spatial configuration of gradient and optical flow patterns. The patterns are learned with an unsupervised learning algorithm based on translation-invariant nonnegative sparse coding called VNMF that extracts prototypical optical flow patterns shaped, for example, as moving heads or limb parts. A key element of the proposed system is a lateral inhibition term that suppresses activations of competing patterns in the learning process, leading to a low number of dominant and topological sparse activations. We analyze the classification performance of the gradient and optical flow patterns on three real-world human action recognition and one face expression recognition data set. The results indicate that the recognition of human actions can be achieved by gradient patterns alone, but adding optical flow patterns increases the classification performance. The combined patterns outperform other biological-inspired models and are competitive with current computer vision approaches.

Abstract
Abstract
Purpose: Trastuzumab (T; Roche) is part of the standard treatment in patients (pts) of any age with early stage, HER2+ breast cancer, in addition to (neo)adjuvant chemotherapy (CT) and locoregional treatment. After its registration in Germany in 2006, this prospective observation study was started in order to assess the generalizability of the results from the randomized studies, specifically with respect to elderly age cohorts.
Methods: 4027 pts were enrolled between 2006 and 2012. 87 were non-eligible due to M1 and/or negative HER2 status. There were no restrictions for recruitment with respect to age or concomitant/sequential adjuvant medication. The long-term relapse/survival status of pts was retrieved by fax forms collected once a year. Safety assessment was limited to the treatment period. Data base cut-off was May 2013.
Results: Among the 3940 evaluable pts, there were 1013 elderly pts (EP) ≥ 65 years (y) of age (26%). This contrasts to the pivotal studies, e.g. with a proportion of only 6% beyond 65 y in the NSABP B-31 and NCCTG N9831 studies. The rate of EP steadily increased during the period from 2006 to 2009, remaining stable thereafter. More than half of the pts had pT≥2, with EP more often presenting with a larger tumor (56% vs. 48%,p<.0001). 52% had a grade 3 tumor. Hormone receptor positivity was recorded in 63%. As to be expected, performance status was more impaired in elderly compared to younger pts (ECOG 0: 53 vs 65%,p<.0001). 94% received CT, 78% as adjuvant, 14% as neoadjuvant treatment (in EP only 8%), while 2% received both modalities. In the vast majority (87%), T was administered sequentially to CT, with no differences among the age cohorts. The proportion without any adjuvant CT was higher in EP (8 vs. 5%). 56% of pts were treated with adjuvant endocrine medication, 78% with irradiation. T treatment was stopped prematurely in only 9% of pts, but more often in EP (11% vs 8%, p = .014).
After a follow-up period of up to a maximum of 8 y, 370 relapses were reported so far. The estimated recurrence-free survival is 94.7% (95% CI: 94-96%), 89.8% (89-91%), and 82.9% (81-85%) after 2, 3 and 5 y, respectively. Numeric results in EP are only slightly lower with 93.9 (92-96%), 89.3% (87-92%), and 81.6% (78-85%), not statistically significant (p = 0.18, HR = 1.17 [95% CI: 0.93 - 1.47]). Adverse effects with respect to cardiac function were reported in overall 153 pts (3.9%), with the majority of these cases of NCI grade 1 (39%) or 2 (38%). 23% of these events were of grade 3/4, but life-threatening in only 2 pts. Thus, the overall incidence of acute grade 3/4 cardiac function toxicity was 0.9%. In the EP subgroup the incidence across all NCI grades was only slightly increased (4.6%), but grade 3/4 cases were more common (1.6%).
Conclusion: Overall, the maturing follow-up data of this observational study confirm the beneficial results from the randomized studies. In addition, the data from more than thousand pts ≥ 65 y of age show that a similar anti-tumor efficiency can be achieved in elderly pts, and suggest that minor age-related differences detected with respect to adjuvant treatment duration, aggressiveness and toxicity do not impair the long-term clinical outcome.

Abstract
A platform consisting of a multi-shock drive and an implosion backlighter has been developed for x-ray absorption fine structure (XAFS) measurements on materials compressed to multi-Mbar pressures. The experimental setup, target design, and backlighter characteristics are presented. Extended XAFS (EXAFS) measurements for various materials have been demonstrated. A quintuple-crystal design is described to enhance the efficiency of the x-ray spectrometer, enabling observation of very weak EXAFS signals in a single shot.

Abstract
ABSTRACT There is limited research about tobacco-related behaviours and attitudes among rural populations in the Eastern Mediterranean Region. The aim of this study was to determine smoking behaviours and attitudes among the nomadic Bedouin in rural southern Jordan. Patients visiting a village clinic over 2 months of 2009 were invited by the attending physician to participate in the survey, which was adapted from the California Tobacco Survey. The smoking prevalence among the 92 participants was 46.7%. Most smokers were men who smoked heavily (> 1 pack/day) (90.7%). There was general low self-efficacy to quit among smokers, yet 81.4% acknowledged that smoking was harming their health. Although 79.1% of smokers and 89.1% of non-smokers believed second-hand smoke was harmful to non-smokers, most of them had no restrictions on smoking for residents and guests (66.3%) and most had children at home (73.9%). These data demonstrate contradictions between attitudes and behaviours about smoking of this rural population.

Abstract
Abstract
Purpose: Trastuzumab (T) was registered in 2006 for the treatment of early stage, HER2+ breast cancer, after surgery, (neo)adjuvant chemotherapy and/or radiotherapy, without specific age restrictions. However, the amount of data on elderly patients (EP) from the randomized studies is only sparse. E.g., in the HERA study, only 16% were ≥60 years (y) of age. In this prospective observation study the routine practice of HER2 antibody treatment in this setting was examined, with a special focus on the EP subgroup.
Methods: At present, 1888 patients (pt) have been enrolled in this ongoing study; 1791 pt from 220 German centres were already sufficiently documented to be analysed. 38 were non-eligible due to either M1 or negative HER2 status.
Results: The proportion of EP (≥65 y) steadily increased during the course of the project, with currently 436/176 (25%/10%) ≥65/≥70 y. As to be expected, performance status was more impaired in elderly compared to younger pt (ECOG 0: 51 vs 65%). EP more often presented with a larger tumor (pT≥2: 58 vs. 51%), while lymph node involvement was rather similar (52% vs. 49%). A positive hormone receptor status was recorded in 60 vs 61%. 92% received chemotherapy (CT), with neoadjuvant placement distinctly less common in EP (8 vs 18%), as well as anthracycline (A, 88 vs 95%) and taxane (Ta, 54 vs 64%) administration. An ATa combination was applied in 47 vs 59% only (p<.0001). A median of 6 CT cycles were given in both age groups. No relevant differences were recorded with respect to concurrent T/CT (15%), endocrine treatment (55%), initial T dosage (median 8 mg/kg) and T duration (mean: 50 weeks). Treatment delays were required in 20%, but not more frequent in EP. Slightly more EP stopped treatment prematurely (11% vs 8%, p=.094). Cardiac status was examined by echocardiography (echo) in 81%, with similar baseline LVEF (median: 65%), but some difference at end of treatment (61 vs 64%, p=.017), with an overall rate of pathologic findings in echo/ECG of 13 vs 6% (p<.0001). However, the rate with LVEF <40% was similar with 2%. Grade ≥2 adverse reactions on cardiac function were reported in 3.7 vs 2.1%. No other severe toxicities related to T occurred with a frequency >1%. After a follow-up period of up to a maximum of 5 years, 111 relapses were hitherto reported. The estimated recurrence-free survival is 95% (95% CI: 94 - 96%) and 89% (87 - 92%) after 2 and 3 years, respectively, with no detectable differences between age groups (p = 0.87). Conclusion: T can be applied safely in early breast cancer, without restrictions with respect to age, with higher age often accounted for by the choice of less aggressive CT. In the elderly, differences in cardiac toxicity and premature withdrawal can be detected, but seem to be of limited absolute magnitude and clinical relevance.

Abstract
Hugoniot data were obtained for fluid He in the 100 GPa pressure range by shock compression of samples statically precompressed in diamond-anvil cells. The initial (precompressed) He density (rho_(1)) for each experiment was tuned to a value between rho_(0L)<rho_(1)<3.3rho_(0L), where rho_(0L) is the zero-pressure density of the cryogenic liquid (rho_(0L)=0.123 g/cm(3)). The maximum observed shock-compression ratios range from rho/rho_(1)=6 for rho_(1)=rho_(0L) to rho/rho_(1)=4 for rho_(1)> or =3rho_{0L} (i.e., rho/rho_(0L)> or =12). Data show an increase in compressibility at the onset of ionization, similar to theoretical predictions.

Abstract
We present for the first time a full three-dimensional (3-D) reconstruction of absorption images of breast from continuous-wave (cw) measurements performed on a premenopausal woman. Our 3-D optical images clearly reveal a large primary tumor as well as a small secondary tumor in a separate location of the breast. The multiple tumors identified by our 3-D optical imaging have been confirmed by the subsequent biopsy examination of the breast. Quantitative information of the optical images obtained is provided in terms of the location, size, and absorption coefficient of the tumors.

Abstract
Models that describe qualitatively and quantitatively the activity of entire groups of spiking neurons are becoming increasingly important for biologically realistic large-scale network simulations. At the systems and areas modeling level, it is necessary to switch the basic descriptional level from single spiking neurons to neuronal assemblies. In this article, we present and review work that allows a macroscopic description of the assembly activity. We show that such macroscopic models can be used to reproduce in a quantitatively exact manner the joint activity of groups of spike-response or integrate-and-fire neurons. We also show that integral as well as differential equation models of neuronal assemblies can be understood within a single framework, which allows a comparison with the commonly used assembly-averaged graded-response type of models. The presented framework thus enables the large-scale neural network modeler to implement networks using computational units beyond the single spiking neuron without losing much biological accuracy. This article explains the theoretical background as well as the capabilities and the implementation details of the assembly approach.

Abstract
Starting from single, spiking neurons, we derive a system of coupled differential equations for a description of the dynamics of pools of extensively many equivalent neurons. Contrary to previous work, the derivation is exact and takes into account microscopic properties of single neurons, such as axonal delays and refractory behavior. Simulations show a good quantitative agreement with microscopically modeled pools of spiking neurons. The agreement holds both in the quasistationary and nonstationary dynamical regimes, including fast transients and oscillations. The model is compared with other pool models based on differential equations. It turns out that models of the graded-response category can be understood as a first-order approximation of our pool dynamics. Furthermore, the present formalism gives rise to a system of equations that can be reduced straightforwardly so as to gain a description of the pool dynamics to any desired order of approximation. Finally, we present a stability criterion that is suitable for handling pools of neurons. Due to its exact derivation from single-neuron dynamics, the present model opens simulation possibilities for studies that rely upon biologically realistic large-scale networks composed of assemblies of spiking neurons.

Abstract
A novel Philadelphia (Ph) variant translocation, t(Y;9;22)(q12;q34;q11), was detected in a 63-year-old man with a newly diagnosed chronic myeloid leukemia (CML). Reverse transcription polymerase chain reaction (RT-PCR) analysis revealed a b3a2 fusion transcript. Fluorescence in situ hybridization (FISH) utilizing library probes, subtelomeric cosmid probes, and probes hybridizing to the ABL and BCR genes showed a reciprocal three-way translocation involving Yq12, 9q34, and 22q11, and a BCR-ABL fusion signal on der(22). The subtelomeric Yq probe hybridizing centromerically to the IL9 receptor gene and covering the centromeric portion of the SYBL1 gene was found to be translocated to der(9).

Abstract
Cyclosporin A has heterogeneous effects on anthracycline-related cardiotoxicity and can prevent multidrug-resistance (MDR). The aim of this study was to explore whether the coadministration of cyclosporin A is accompanied by an increase in cardiotoxicity. Forty-three patients (27 male, 16 female, age: 18-67 yrs [mean: 47.5 yrs, SD: 11.6 yrs]) received 177 radionuclide ventriculography examinations (RNV 177 at rest, 133 at stress) before and during chemotherapy with either doxorubicin (n = 23) or epirubicin (n = 20). RNV studies were applied up to 11 times in the follow-up of the patients. A maximum of 10 courses of chemotherapy was performed. In the doxorubicin group only, the age of the patients and the cumulative dose of the chemotherapeutic agent had a significant negative impact on left ventricular ejection fractions, whereas cyclosporin A had a significant positive influence (multiple analysis of regression, p < 0.05). Cyclosporin A did not cause any significant increase in cardiotoxicity in our patients.

Abstract
There is still controversy as to what constitutes the optimal therapy for acute and delayed chemotherapy-induced emesis and nausea. We conducted a three-armed randomized multi-centre study in 193 chemotherapy-naive patients receiving highly emetogenic chemotherapy inducing both acute and delayed symptoms (cisplatin > or = 50 mg/m2, carboplatin > or = 300 mg/m2, cyclophosphamide > or = 750 mg/m2, ifosfamide > or = 1.5 g/m2 on day 1). Group A: 1 x 5 mg tropisetron i.v. on day 1 + 2, then 10 mg p.o. (oral dose now recommended: 5 mg); group B: tropisetron as for A+dexamethasone, 20 mg i.v., on days 1 + 2, then 4 mg i.v./p.o.; group C: tropisetron as for A+metoclopramide, 20 mg i.v. +2 x 10 mg p.o. on day 1, then 3 x 10 mg p.o. Treatment was continued for at least 2 days after the end of chemotherapy. Tropisetron+dexamethasone was significantly superior to tropisetron alone both for acute (P = 0.0064) and delayed (P = 0.0053) emesis. Complete control of acute and delayed emesis (nausea) was achieved in 80% (75%) and 53% (46%) in group A, 97% (90%) and 80% (58%) in group B, and 86% (80%) and 49% (45%) in group C. Patients completely asymptomatic during the whole cycle accounted for 26% of those in group A, 49% in group B and 28% in group C. The most frequent adverse events were constipation (16.6%), headache (7.3%) and tiredness (7.3%). Once-daily tropisetron+dexamethasone over several days is well tolerated and is a simple means of achieving further significant improvement in the efficacy of tropisetron against acute and delayed symptoms.

Abstract
We report an open, three-armed, multicenter study being carried out to assess the optimum treatment for acute and delayed emesis and nausea in patients undergoing highly emetogenic chemotherapy. Eighty-seven patients were randomized to receive tropisetron (Navoban; Sandoz Pharma Ltd, Basel, Switzerland), tropisetron plus dexamethasone, or tropisetron plus metoclopramide during chemotherapy. Tropisetron in combination with dexamethasone produced the best control of both acute and delayed emesis. Acute vomiting was prevented in 69% of patients by tropisetron monotherapy, and the addition of dexamethasone significantly increased the total control of vomiting to 92% (P < .01). Similarly for delayed vomiting, total control of emesis was seen in approximately 70% of patients on tropisetron alone during days 2 and 3; this control rate increased to almost 90% with combined tropisetron/ dexamethasone treatment. In all patients receiving cisplatin, the tropisetron/dexamethasone combination produced total control of acute emesis. The tropisetron and dexamethasone combination also provided the best control of acute and delayed nausea. Tropisetron produced total control of acute nausea in 69% of patients. The addition of dexamethasone increased this control rate to 81%. Similarly for delayed nausea, on days 2 and 3 of treatment, dexamethasone plus tropisetron provided total control of nausea in more than 80% of patients compared with a control rate of more than 60% achieved using tropisetron. The combination of tropisetron and metoclopramide did not improve significantly on the control of nausea and vomiting achieved using tropisetron alone. Evaluation of quality of life events by patients indicated no appreciable change in their mental or physical condition during chemotherapy, irrespective of antiemetic therapy. In the tropisetron and tropisetron plus metoclopramide treatment groups, a decreased food intake was observed due to delayed nausea while the addition of dexamethasone prevented loss of appetite. The antiemetic treatments were similarly well tolerated. The most common adverse events were constipation (15%) and tiredness (7%).

Abstract
This study compares prostaglandin E2 (PGE2) gel and oxytocin for the initiation of labor in term pregnancies with a moderately favorable cervix (Bishop score 5-8). Compared with a matched group, 48 cases treated with PGE2 gel (2.5 mg intravaginally) required significantly less or no oxytocin, had shorter first stages of active labor, and had no increased risk of uterine hyperstimulation or cesarean section. Initiation of labor with low dose PGE2 when the cervix is moderately favorable is less labor intensive and meets with more patient satisfaction.

Abstract
Monocyte antibody-dependent cell-mediated cytotoxicity (ADCC) was compared to intrinsic cyclic-adenosine-monophosphate (cAMP) levels in 14 patients with systemic sclerosis. Depressed monocyte cytotoxicity was observed. Elevated cAMP levels (2-5 times) in resting monocytes were found in 5 patients; the rest had normal cAMP values. Monocyte ADCC was inversely correlated to cellular cAMP content (r = -0.6659, P less than 0.02). Scleroderma patients with high basal cAMP levels showed impaired responses to beta-adrenergic stimulation but not to prostaglandin E (PGE1) and histamine. Patients with normal basal cAMP levels showed no defect in beta-adrenergic responses. No close correlation between monocyte abnormality and clinical state was found.
