Discryption: Internal Hard-Disk Encryption for Secure Storage (2007)

There have been many recent cases of information getting into unauthorized hands from lost or stolen laptops or insiders accessing unattended enterprise computers or storage devices. Providing physical protection and using remote locations are two means of keeping stored data confidential. The least expensive secure-storage systems use local data encryption with optional data authentication, together with access control and physical tamper detection. The IEEE P1619 Security in Storage Working Group is developing standard architectures for external encryption modules and tape drives. However, there's no standard yet for hard disks, specifying how developers can adapt the data layout to security needs and provide access control to the encrypted data. That means an attacker can only see the ciphertext after disassembling the drive and examining the magnetic platters with multimillion-dollar equipment. And because of the attacks' destructive nature, if the disk drive is returned, the owner will notice the disk was tampered with and won't trust the stored information. This effectively renders all kinds of data-modification attacks harmless.

Identification of a novel gene, <i>FGFR1OP2</i>, fused to <i>FGFR1</i> in 8p11 myeloproliferative syndrome (2004)

The 8p11 myeloproliferative syndrome (EMS) is an aggressive hematological malignancy caused by the fusion of diverse partner genes to fibroblast growth factor receptor 1 (FGFR1). The partner proteins promote dimerization and ligand-independent activation of FGFR1-encoded tyrosine kinase, deregulating hemopoiesis in a manner analogous to BCR-ABL in chronic myeloid leukemia. Here, we describe the identification of a new FGFR1 fusion gene in a patient who presented with T-cell lymphoblastic lymphoma in conjunction with an acquired ins(12;8)(p11;p11p22). Initial FISH analysis and Southern blotting confirmed that FGFR1 was disrupted. Using 5'-RACE PCR, we identified part of a novel gene, FGFR1OP2, at chromosome band 12p11 that was fused to exon 9 of FGFR1.FGFR1OP2 is predicted to be translated into an evolutionarily conserved protein containing coiled-coil domains but no other recognizable motifs. The presence of the chimeric gene was confirmed by RT-PCR, genomic DNA PCR, and FISH. These data further support the central role of deregulated FGFR1 in the pathogenesis of EMS.
Characterization and management of various renal cystic lesions by sonographic features (2018)

Renal cysts are common incidental findings in clinical practice. Most renal cysts detected in medical imaging are benign simple cysts. However, some are complicated by hemorrhage or infection or are associated with calcification. In these instances, difficulties can be encountered distinguishing the complicated cysts from cystic renal tumors such as cystic renal cell carcinoma, multilocular cystic nephroma, and mixed epithelial and stromal tumors. The Bosniak classification is widely used to categorize cystic renal lesions but is used to classify those discovered via computed tomography. Ultrasonography (US) and color Doppler US are the most frequently used imaging techniques for abdominal surveys and long-term follow-up because of their noninvasiveness, relatively low cost, wide availability, and frequently, lack of contrast medium. Herein, we review the features of various cystic lesions of the kidney that can be found using US, discuss differential diagnoses using US, and propose a feature-oriented algorithmic approach to classifying renal cystic lesions using US.
Local phase transitions from off-to on-center defects under hydrostatic pressure, studied with optical and dielectric techniques (1977)

The shallow multi-well potential of several low symmetry off-center point-defects in alkali-halides can be tuned by hydrostatic pressure into a centro-symmetric single-well potential. This has been monitored in KCl: Li+, RbCl: Ag, RbBr: Ag+ and NaBr: Cu+ by the real and imaginary dielectric response of the off-center dipoles and partly by the forbidden d → s uv transitions (which get partially allowed in the odd parity off-center potential). Both properties display a rather abrupt disappearance of the off-center dipole moment at a critical pressure, characteristic for each defect system. The dielectric data show the corresponding decrease of the orientational barrier, leading eventually to tuning from classical into tunneling behavior, and for KCl: Li+ to a pronounced increase of the tunneling splitting.
The Molecular and Electronic Structure of Tris(dimethylarsino)amine (Me<sub>2</sub>As)<sub>3</sub>N (1999)

The molecular structure of tris(dimethylarsino)amine has been determined by X-ray diffraction methods. The compound has a planar AS 3 N core unit with a paddle-wheel conformation of the three Me 2 As groups. This structure was also confirmed by density functional calculations.
IBR und BVD-Bekämpfung: der Schlüssel für erfolgreiches Herden-Management [Tagungsbericht, Symposium "IBR and BVD control", Prag, Juni 2010] (2010)

Wissenschaftlich und praktisch tätige Tierärzte aus 17 Europäischen Ländern trafen sich im Juni 2010 im schönen Prag, um ihr Wissen und ihre Erfahrungen über die Bekämpfung der infektiösen bovinen Rhinotracheitis (IBR) und der bovinen Virus-Diarrhoe (BVD) auszutauschen. Mehr als 60 Teilnehmer (Abb. 1) aus den unterschiedlichen Ländern folgten der Einladung von Professor Thiry (Universität Liege, Belgien), und nahmen am 2-tägigen Symposium teil, das von der Intervet/Schering-Plough Animal Health, Boxmeer unterstützt wurde. Alle 18 Expertenbeiträge wurden sehr rege diskutiert. Der erste Tag war der Bekämpfung von IBR gewidmet, während BVD das Thema des zweiten Tages darstellte. Beide Tage begannen mit einer Vortragsreihe, die jeweils generelle Aspekte ansprach. Weitere Vorträge über Strategien und Erfolge der Bekämpfung der beiden Seuchen in verschiedenen Ländern bildeten den Auftakt für eine jeweils umfassende "Round-Table"-Diskussion. Alle Experten stimmten darin überein, dass alle notwendigen Elemente für eine erfolgreiche IBR- und BVD-Bekämpfung vorhanden sind, wie Impfstoffe und Diagnostika. Jedoch hängt der Erfolg eines Bekämpfungsprogramms wesentlich vom systematischen und nachhaltigen Einsatz der Maßnahmen ab.
Inhibition of DNA synthesis and G1/S-phase transition in normal human fibroblasts elicited by a heat-labile trans-acting factor in gamma-irradiated HeLa cell extracts. (1997)

Proliferating human cells exposed to ionizing radiation show complex cellular responses including a delay in progression through various phases in the cell cycle. These cell cycle checkpoints are regulated by mitogenic signaling pathways which transduce the extracellular signals to the cell cycle control machinery. In this study we demonstrate that microinjection of a cellular extract, prepared from gamma-irradiated (40 Gy) HeLa cells, into the cytoplasm of normal human fibroblasts results in suppression of DNA replicative synthesis, indicating the presence of a trans-acting DNA synthesis-inhibiting factor(s). The addition of this same extract to the culture medium for a short time (< or = 2 h) also inhibits DNA synthesis in human fibroblasts, affecting both replicon initiation and DNA chain elongation processes. Moreover, a 2-h incubation of the fibroblast cultures with the extract causes a transient delay in cell progression from G1 to S phase coupled with up-regulation of the p53 tumor suppressor protein. Both the DNA synthesis-inhibiting and G1-phase-blocking activities are reduced markedly when the extract is heated (80 degrees C; 10 min) prior to its addition to the culture medium. On the other hand, pretreatment of the fibroblast cultures with KN62, an inhibitor of calmodulin-dependent kinase II (CaMKII), serves to abrogate the inhibitory effect of the extract on DNA synthesis without influencing its ability to induce the G1-phase block. These results are compatible with the presence in HeLa cell extracts of a heat-labile trans-acting factor that triggers, in normal human cells, the activation of (1) a CaMKII-dependent signal transduction pathway mediating suppression of DNA synthesis and (2) a p53-dependent pathway mediating G1-phase checkpoint control.
Pressure Effects on Geometry and Structure of Gas Jet Flames in Crossflow (2001)

Flame structure and geometry of natural gas andpropanediffusion  ames in cross ow are presented to delineate the effects of buoyancyand ambientpressure. The fuel was injected horizontally into a verticallymovingairstream. The buoyancy acted along the direction of the cross ow. The combustion-chamber pressure was varied from 1 to 1.45 bar and the cross ow to jet velocity ratio from 0.1 to 1.45. Quantitative rainbow schlieren de ectometry was used to visualize the  ame and to measure the geometrical parameters. The centerline  ame trajectory showed three distinct regions, and the dimensionless coordinate of the jet centerline in the jet direction varied with 0.45, 0.25, 0 power of the coordinate in the cross ow direction and i 0.5 power of the Froude number based on the jet velocity in these regions. The  ame trajectories did not change signi cantly with pressure. Flame chord length varied with 0.45 power of the cross ow/jet velocity ratio. Flame length and soot formation characteristics changed notably with pressure. Propane  ames were more susceptible than natural gas  ames to the ambient pressure. The  ame luminosity caused by soot in the propane  ame changed only slightly with velocity ratio. However, the natural gas  ame became nonsooty at high velocity ratios.
Auxin regulation of cytokinin biosynthesis in <i>Arabidopsis thaliana</i> : A factor of potential importance for auxin–cytokinin-regulated development (2004)

One of the most long-lived models in plant science is the belief that the long-distance transport and ratio of two plant hormones, auxin and cytokinin, at the site of action control major developmental events such as apical dominance. We have used in vivo deuterium labeling and mass spectrometry to investigate the dynamics of homeostatic cross talk between the two plant hormones. Interestingly, auxin mediates a very rapid negative control of the cytokinin pool by mainly suppressing the biosynthesis via the isopentenyladenosine-5'-monophosphate-independent pathway. In contrast, the effect of cytokinin overproduction on the entire auxin pool in the plant was slower, indicating that this most likely is mediated through altered development. In addition, we were able to confirm that the lateral root meristems are likely to be the main sites of isopentenyladenosine-5'-monophosphate-dependent cytokinin synthesis, and that the aerial tissue of the plant surprisingly also was a significant source of cytokinin biosynthesis. Our demonstration of shoot-localized synthesis, together with data demonstrating that auxin imposes a very rapid regulation of cytokinin biosynthesis, illustrates that the two hormones can interact also on the metabolic level in controlling plant development, and that the aerial part of the plant has the capacity to synthesize its own cytokinin independent of long-range transport from the root system.
Insulator interface effects in sputter-deposited NbN/MgO/NbN (superconductor–insulator–superconductor) tunnel junctions (1987)

All refractory, NbN/MgO/NbN (superconductor–insulator–superconductor) tunnel junctions have been fabricated by in situ sputter deposition. The influence of MgO thickness (0.8–6.0 nm) deposited under different sputtering ambients at various deposition rates on current–voltage (I–V) characteristics of small-area (30×30 μm) tunnel junctions is studied. The NbN/MgO/NbN trilayer is deposited in situ by dc reactive magnetron (NbN), and rf magnetron (MgO) sputtering, followed by thermal evaporation of a protective Au cap. Subsequent photolithography, reactive ion etching, planarization, and top contact (Pb/Ag) deposition completes the junction structure. Normal resistance of the junctions with MgO deposited in Ar or Ar and N2 mixture shows good exponential dependence on the MgO thickness indicating formation of a pin-hole-free uniform barrier layer. Further, a postdeposition in situ oxygen plasma treatment of the MgO layer increases the junction resistance sharply, and reduces the subgap leakage. A possible enrichment of the MgO layer stoichiometry by the oxygen plasma treatment is suggested. A sumgap as high as 5.7 mV is observed for such a junction.

Aging and genetic variation of plasma apolipoproteins. Relative loss of the apolipoprotein E4 phenotype in centenarians. (1994)

We determined the common polymorphism of apolipoprotein E (E2, E3, and E4), apolipoprotein B Xba I polymorphism, and apolipoprotein C-III Sst I polymorphism in almost all Finnish centenarians alive in 1991 (n = 179/185). Plasma lipid and lipoprotein levels in different apolipoprotein genotypes were also measured. In comparison with younger Finnish populations studied previously, the frequency of the apolipoprotein E epsilon 2 allele was almost twice as high (7.0% versus 4.1%; P < .05) and that of the epsilon 4 allele only approximately one third as high (8.4% versus 22.7%; P < .001) in the centenarians. Plasma cholesterol and high-density lipoprotein cholesterol levels tended to be lowest in the group with the epsilon 2 allele (4.33 mmol/L and 1.41 mmol/L, respectively), intermediate in those with the epsilon 3 allele (4.57 mmol/L and 1.48 mmol/L, respectively), and highest in those with the epsilon 4 allele (4.82 mmol/L and 1.60 mmol/L, respectively). The frequencies of the apolipoprotein B X1 and X2 alleles (Xba I restriction site absent or present, respectively) among the centenarians and among the young Finns were not significantly different, whereas the apolipoprotein C-III S2 allele (Sst I restriction site present) occurred more often in the centenarians (frequency, 12.9%) than in the youngest reference population (frequency, 8.8%; P < .05). Centenarians with the apolipoprotein B X2X2 genotype and apolipoprotein E4 phenotype had a higher mean plasma cholesterol level than those with the X1X1 genotype and E2 phenotype (5.24 versus 3.43 mmol/L; P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of temperature on the solid-state molecular structure of [Fe3(CO)12] (1994)

The molecular and crystal structure of [Fe3(CO)12] has been reinvestigated from single-crystal X-ray diffraction data collected at 100, 160, 250 and 320 K. The asymmetric bridging carbonyl ligands become progressively more symmetric as the temperature is decreased. At the lowest temperature the molecule possesses nearly exact C2v, symmetry. The crystal structure has been examined in the two limiting hypothetical P21 and P1 crystals composing the disordered P21/n structure.
Diagnostic Accuracy of Ultrasound Above and Below the Beta-hCG Discriminatory Zone (1999)

In Brief Objective To evaluate clinical use and accuracy of transvaginal ultrasound for diagnosing intrauterine pregnancies, spontaneous miscarriages, and ectopic pregnancies in women who present with β-hCG concentrations above or below an established discriminatory zone. Methods Ultrasound diagnosis at presentation was compared with final clinical diagnosis in 333 consecutive pregnant women who presented to an emergency department with vaginal bleeding or abdominal pain. The sensitivity, specificity, predictive value, and overall diagnostic accuracy of ultrasound were calculated. Results Transvaginal ultrasound was nondiagnostic in 59 (17.7%) of 333 subjects and 43 (67.2%) of 64 subjects with β-hCG levels below 1500 mIU/mL at presentation. Preliminary ultrasound diagnoses were reported significantly more frequently when presenting β-hCG levels were above 1500 mIU/mL (253 [94.1%] of 269 subjects) compared with levels below 1500 mIU/mL (21 [32.8%] of 64 subjects: P < .001; relative risk (RR) 3.4 [95% confidence interval (CI) 2.23, 5.18]). The proportion of accurate preliminary ultrasound diagnoses was significantly higher in subjects who presented with β-hCG levels above 1500 mIU/mL (227 [91.5%] of 248 subjects) compared with levels below 1500 mIU/mL (18 [28.6%] of 63 subjects: P < .001; RR 2.9 [95% CI 2.04, 4.15]). Sensitivity of transvaginal ultrasound diagnosis of intrauterine pregnancy, spontaneous miscarriage, and ectopic pregnancy in women who presented with β-hCG levels below 1500 mIU/mL was 33.3%, 28.2%, and 25.0%, respectively. Conclusion The sensitivity, predictive value, and accuracy of transvaginal ultrasound for diagnosing complications of early pregnancy were poor when β-hCG levels were below the discriminatory zone at presentation. Ultrasound impressions should be correlated with β-hCG concentrations. Ultrasound has low sensitivity, predictive value, and accuracy for diagnosing pregnancy and complications in women with β-hCG levels below the discriminatory zone.

Zur Schätzung energetischer Futterwerte von Mischfutter‐ mitteln für Rinder (1981)

Zusammenfassung An einem Material von 54 Mischfuttermitteln für Rinder wurden Regressionsgleichungen zur Schätzung verschiedener energetischer Futterbewertungen (ME, StE, NEL, NEF r ) mit‐tels verschiedener Nährstoffanalysen erstellt. Im einzelnen wurden dabei die erklärenden Variablen in jeweils drei Gruppen zusammengefaßt, wobei in alien Gruppen Rohprotein, Rohfett und Stärke gleich waren. Verschieden war in den einzelnen Gruppen neben der Fa‐ser (Rohfaser, NDF, ADF) der sich jeweils dann ergebende organische Rest. Für alle Ener‐giebewertungen wurden in den einzelnen Gruppen multiple Regressionsgleichungen mit und ohne Intercept errechnet und die Schätzgenauigkeit durch den absoluten sowie relativen Standardschätzfehler sowie durch das Bestimmtheitsmaß charakterisiert. Verglichen mit den Gleichungen, bei denen Rohfaser als Variable verwendet wurde, brachte für die Schätzung der Mischfuttermittel für Rinder die Verwendung von NDF bzw. ADF keine verbesserten Ergebnisse.
The hydrogen evolution reaction and hydrogen oxidation reaction on thin film PdAu alloy surfaces (2010)

A high throughput synthetic and screening methodology has been applied to the study of the Hydrogen Evolution Reaction (HER) and Hydrogen Oxidation Reaction (HOR) activities of PdAu thin film alloy surfaces. A compositional gradient method has been used to produce non-equilibrium surfaces of PdAu solid solution alloys. XPS shows surface compositions for these un-annealed alloys to be the same as the bulk, in contrast to the observed and expected behaviour of annealed alloys. The surface redox behaviour of the alloys provides direct evidence for the existence of Pd ensembles with distinctive surface chemistry dominating the oxygen interaction at intermediate alloy compositions. CO stripping voltammetry indicates that alloying of Pd with Au results in a strong poisoning of CO adsorption with the exception of CO adsorbed on Pd monomers. The compositional dependence of the HER and HOR activities is strongly correlated on the alloy surfaces, with a maximum in geometric activity observed at 60 at% Au, corresponding to a maximum in specific activity at 70 at% Au, for both reactions. This activity is associated with Pd poor ensembles. There is some evidence that while the Pd monomer catalyses the HER, HOR is not sustained at compositions where the monomer is present.
Design and performance of an integrated envelope/lighting system (1997)

Dynamic envelope/ lighting systems offer the potential to achieve a near optimum energy-efficient environment meeting occupant needs throughout the year by adapting to dynamic meteorological conditions and changing occupant preferences in real time.With the dramatic increased functionality of the microprocessor, there is an untapped potential to make dynamic envelope/lighting systems easier to use, diagnose, and monitor, and to integrate them as part of a sophisticated buildingwide control system.This study addresses the complex relationship between this energy-efficiency technology and many of the non-energy issues related to its potential acceptance by the building industry, architects, owners, and users.We demonstrate the concept of integrated dynamic systems with a prototype motorized venetian blind operated in synchronization with electric lighting and daylighting controls via an intelligent control system.Research work conducted with simulation software and reduced-scale and full-scale field tests is summarized.Much of this work is directly relevant to other active shading and daylighting systems on the market today and to state-of-the-art window systems yet to come (i.e., electrochromics).
