Search for long-lived charginos based on a disappearing-track signature using 136 fb$$^{-1}$$ of pp collisions at $$\sqrt{s}$$ = 13 TeV with the ATLAS detector (2022)

Abstract A search for long-lived charginos produced either directly or in the cascade decay of heavy prompt gluino states is presented. The search is based on proton–proton collision data collected at a centre-of-mass energy of $$\sqrt{s}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mi>s</mml:mi> </mml:msqrt> </mml:math> = 13 T $$\text {eV}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mtext>eV</mml:mtext> </mml:math> between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 136 fb $$^{-1}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mrow/> <mml:mrow> <mml:mo>-</mml:mo> <mml:mn>1</mml:mn> </mml:mrow> </mml:msup> </mml:math> . Long-lived charginos are characterised by a distinct signature of a short and then disappearing track, and are reconstructed using at least four measurements in the ATLAS pixel detector, with no subsequent measurements in the silicon-microstrip tracking volume nor any associated energy deposits in the calorimeter. The final state is complemented by a large missing transverse-momentum requirement for triggering purposes and at least one high-transverse-momentum jet. No excess above the expected backgrounds is observed. Exclusion limits are set at 95% confidence level on the masses of the chargino and gluino for different chargino lifetimes.

Secure Context Switching of Masked Software Implementations (2023)

Cryptographic software running on embedded devices requires protection against physical side-channel attacks such as power analysis. Masking is a widely deployed countermeasure against these attacks and is directly implemented on algorithmic level. Many works study the security of masked cryptographic software on CPUs, pointing out potential problems on algorithmic/microarchitecture-level, as well as corresponding solutions, and even show masked software can be implemented efficiently and with strong (formal) security guarantees. However, these works also make the implicit assumption that software is executed directly on the CPU without any abstraction layers in-between, i.e., they focus exclusively on the bare-metal case. Many practical applications, including IoT and automotive/industrial environments, require multitasking embedded OSs on which masked software runs as one out of many concurrent tasks. For such applications, the potential impact of events like context switches on the secure execution of masked software has not been studied so far at all.
A compact polymer–inorganic hybrid gas barrier nanolayer for flexible organic light-emitting diode displays (2022)

Abstract Atomic layer infiltration technology allows the formation of a nanometer-thick polymer-inorganic hybrid barrier layer in polymer material for flexible organic light-emitting diode (OLED) displays. In this study, according to transmission electron microscopy and secondary-ion mass spectrometry analysis results under various process conditions, a compact polymer-inorganic hybrid nanolayer was successfully formed in a polymer and good barrier performance was revealed with a low water vapor transmission rate under optimal process conditions. Additionally, through gas chromatography-mass spectrometry measurements after ultra-violet radiation testing, polymer out-gassing decreased compared to bare polymers. Based on barrier properties, the polymer with a polymer-inorganic hybrid barrier nanolayer was applied to a flexible OLED display as a substrate. During storage tests and folding tests, the flexible OLED display exhibits good reliability and better flexibility compared to those with an inorganic barrier layer. These results confirm that the polymer-inorganic hybrid nanolayer is suitable for barrier layer formation in flexible OLED displays.
Induction of p53-Independent Apoptosis by Simian Virus 40 Small t Antigen (2001)

Simian virus 40 small t antigen (st) is required for optimal transformation and replication properties of the virus. We find that in certain cell types, such as the human osteosarcoma cell line U2OS, st is capable of inducing apoptosis, as evidenced by a fragmented nuclear morphology and positive terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling staining of transfected cells. The cell death can be p53 independent, since it also occurs in p53-deficient H1299 cells. Genetic analysis indicates that two specific mutants affect apoptosis induction. One of these (C103S) has been frequently used as a PP2A binding mutant. The second mutant (TR4) lacks the final four amino acids of st, which have been reported to be unimportant for PP2A binding in vitro. However, TR4 unexpectedly fails to bind PP2A in vivo. Furthermore, a long-term colony assay reveals a potent colony inhibition upon st expression, and the behavior of st mutants in this assay reflects the relative frequency of nuclear fragmentation observed in transfections using the same mutants. Notably, either Bcl-2 coexpression or broad caspase inhibitor treatment could restore normal nuclear morphology. Finally, fluorescence-activated cell sorting analysis suggests a correlation between the ability of st to modulate cell cycle progression and apoptosis. Taken together, these observations underscore that st does not always promote proliferation but may, depending on conditions and cell type, effect a cell death response.

Current-mode multi-path excess loop delay compensation for GHz sampling CT ΣΔ ADCs (2017)

This paper proposes both system-level and circuit-level solutions of a current-mode multi-path excess loop delay (ELD) compensation technique for continuous-time (CT) ΣΔ ADCs with multi-bit quantization and several GHz sampling rate. Thanks to the proposed solutions, the amplifier of the loop filter is not in the fast feedback (FB) loop; the delay of the pre-amplifier of the comparator is removed; and the effective regeneration time of the comparator latch is maximized. The proposed novelties enable CT ΣΔ ADCs with wide signal bandwidth and improved power efficiency. Extensive transistor-level simulations demonstrate their effectiveness and robustness. This work validates the proposed methods by transistor level design and simulations of an 8.4 GHz MASH ΣΔ ADC achieving an SNDR of 71 dB in a signal band of 600 MHz. This shows that our proposed solutions enable power-efficient multi-GHz ΣΔ ADC applications.
Broadband, Polarization-Sensitive Photodetector Based on Optically-Thick Films of Macroscopically Long, Dense and Aligned Carbon Nanotubes (2013)

Increasing performance demands on photodetectors and solar cells require the development of entirely new materials and technological approaches. We report on the fabrication and optoelectronic characterization of a photodetector based on optically-thick films of dense, aligned, and macroscopically long single-wall carbon nanotubes. The photodetector exhibits broadband response from the visible to the mid-infrared under global illumination, with a response time less than 32 μs. Scanning photocurrent microscopy indicates that the signal originates at the contact edges, with an amplitude and width that can be tailored by choosing different contact metals. A theoretical model demonstrates the photothermoelectric origin of the photoresponse due to gradients in the nanotube Seebeck coefficient near the contacts. The experimental and theoretical results open a new path for the realization of optoelectronic devices based on three-dimensionally organized nanotubes.
Emission wavelength control of InAs/GaAs quantum dots using an As2 source for near-infrared broadband light source applications (2021)

Abstract Herein, we report an emission wavelength control technique for self-assembled InAs quantum dots (QDs) grown via molecular beam epitaxy using an As 2 source (As 2 -QDs). The As 2 -QDs exhibited photoluminescence with a shorter center wavelength and larger bandwidth than those of the QDs grown using an As 4 source. In addition, the emission center wavelength could be controlled by adjusting the time between the growth and capping of the As 2 -QDs. We utilized the multilayer stack of emission-wavelength-controlled As 2 -QDs to fabricate an electrically-driven light source and demonstrated its broadband (approximately 130 nm) emission in the 1–1.3 μ m wavelength range.
Data from Functional Protein Pathway Activation Mapping of the Progression of Normal Skin to Squamous Cell Carcinoma (2023)

&lt;div&gt;Abstract&lt;p&gt;Reverse phase protein microarray analysis was used to identify cell signaling derangements in squamous cell carcinoma (SCC) compared with actinic keratosis (AK) and upper inner arm (UIA). We analyzed two independent tissue sets with isolation and enrichment of epithelial cells by laser capture microdissection. Set 1 served as a pilot and a means to identify protein pathway activation alterations that could be further validated in a second independent set. Set 1 was comprised of 4 AK, 13 SCC, and 20 UIA. Set 2 included 15 AK, 9 SCCs, and 20 UIAs. Activation of 51 signaling proteins, known to be involved in tumorigenesis, were assessed for set 1 and showed that the MEK–ERK [mitogen-activated protein (MAP)/extracellular signal-regulated (ERK; MEK)] pathway was activated in SCC compared with AK and UIA, and that epidermal growth factor receptor (EGFR) and mTOR pathways were aberrantly activated in SCC. Unsupervised two-way hierarchical clustering revealed that AK and UIA shared a common signaling network activation architecture while SCC was dramatically different. Statistical analysis found that prosurvival signaling through phosphorylation of ASK and 4EBP1 as well as increased Bax and Bak expression was higher in AK compared with UIA. We expanded pathway network activation mapping in set 2 to 101 key signaling proteins, which corroborated activation of MEK–ERK, EGFR, and mTOR pathways through discovery of a number of upstream and downstream signaling molecules within these pathways to conclude that SCC is indeed a pathway activation–driven disease. Pathway activation mapping of SCC compared with AK revealed several interconnected networks that could be targeted with drug therapy for potential chemoprevention and therapeutic applications. &lt;i&gt;Cancer Prev Res; 5(3); 403–13. ©2012 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;

Minimum FGF2 Binding Structural Requirements of Heparin and Heparan Sulfate Oligosaccharides As Determined by NMR Spectroscopy (2008)

Heparin and heparan sulfate (HS) glycosaminoglycans (HSGAGs) are sulfated polysaccharidesthat play important roles in fundamental biological processes by binding to proteins. The prototypic exampleof HSGAG-protein interactions is that with the fibroblast growth factors (FGFs), specifically FGF1 andFGF2. Structural and biochemical studies have shown that the chain length, sulfation pattern, andconformation of HSGAGs play a critical role in FGF binding and activity. Previously, we showed that atetrasaccharide of the form ANS,6X-I2S-ANS,6X-I2S-OPr (where X is OH or O-sulfate and Pr is propyl) withat least one of the ANS,6X residues having a 6-O sulfate group was the minimum binding motif for FGF1[Guerrini, M., Agulles, T., Bisio, A., Hricovini, M., Lay, L., Naggi, A., Poletti, L., Sturiale, L., Torri, G.,and Casu, B. (2002) Biochem. Biophys. Res. Commun. 292, 222-230]. We report NMR structural analysisusing two-dimensional NOE spectroscopy (2D-NOESY) and transferred NOESY (trNOESY) on a non-6-O-sulfated synthetic tetrasaccharide TETRA (ANS-I2S-ANS-I2S-OPr) both in its free state and bound toFGF2. This tetrasaccharide comprises both the structural trisaccharide motif ANS-I2S-ANS that forms "kinks"in longer heparin chains induced by FGF binding [Raman, R., Venkataraman, G., Ernst, S., Sasisekharan,V., and Sasisekharan, R. (2003) Proc. Natl. Acad. Sci. U.S.A. 100, 2357-2362] and the common bindingmotif I2S-ANS-I2S present in octasaccharides that exhibited strong FGF2 binding [Kreuger, J., Salmivirta,M., Sturiale, L., Gimenez-Gallego, G., and Lindahl, U. (2001) J. Biol. Chem. 276, 30744-30752]. Thesedata suggest that TETRA could be the shortest HSGAG oligosaccharide that binds to FGF2. Furthermore,our study confirms that both the IdoA residues in TETRA adopt the chair 1C4 conformation upon FGF2binding to provide the best molecular fit in contrast to an analogous 6-O-sulfated tetrasaccharide motifobserved in the FGF2-HSGAG cocrystal structure where one of the IdoAs adopts skew-boat 2SOconformation. Thus, our study highlights the fact that the conformational plurality of IdoA is able toaccommodate the changes in the sulfation pattern to provide the necessary specificity for protein binding.
Development of a Socketed Foundation for the Midwest Weak Post (MWP) V1 (2014)

A socketed foundation was designed and evaluated for use with the Midwest Weak Post (MWP), Version 1. Dynamic component testing was conducted on five different design configurations with varying embedment depths, steel reinforcement, and soil conditions. The low strength of the MWPs limited the force transferred into the foundations and prevented damage in the form of concrete cracking or fracture. Additionally, the lateral movements of the socketed foundations were all within the 1-in. (25-mm) limit established to ensure reuse of the foundations without resetting. The selected design consisted of a 12-in. (305-mm) diameter concrete shaft reinforced with four vertical bars and transverse hoop steel spaced at 6½ in. (165 mm) on center. A 4-in. x 3-in. x ¼-in. (102-mm x 76-mm x 6-mm) steel tube socket was placed in the middle of the shaft. Finally, guidelines were given for the length, or embedment depth, of the foundation based on surrounding soil conditions and risk of frost heave.
Comparative study of intraocular lens implantation through 3.0 mm temporal clear corneal and superior scleral tunnel self-sealing incisions (1997)

Both incisions offered satisfactory clinical results, but the superior scleral tunnel incision resulted in fewer complications. Minimal corneal keratometric change induced by a 3.0 mm incision was not related to uncorrected visual rehabilitation.
Structure and Process Optimization for the Use of a Polymeric Relative-Permeability Modifier in Conformance Control (2003)

Summary For many years, relative-permeability modifiers (RPMs) have received a great deal of attention from the oil- and gas-production industry. Because of the completion techniques used in many wells, it is not always practical or cost-effective to protect the hydrocarbon interval properly during a water-shutoff treatment. RPMs offer the option of bullheading a treatment without zonal isolation, which is designed to decrease water production with little or no decrease in oil or gas production. This paper describes the laboratory development and optimization of a polymeric RPM. The resulting material can be best described as a brush polymer consisting of a polymeric backbone grafted with methoxypolyethylene glycol (MPEG). Various phases of the development will be discussed, such as the optimization of the molecular weight of the backbone polymer and the concentration of grafted MPEG. Details of laboratory evaluations will also be provided, including a discussion of the use of multipressure-tap flow cells for permeability-reduction tests, the effect of polymer concentration, and the effect of saturations. These test results show that the RPM polymer should be placed with a systematic approach consisting of proper preflushes and postflushes for optimum results.

Incidence, Diagnosis and Repair of a Diaphragmatic Hernia Following Hepatic Surgery: A Single Center Analysis of 3107 Consecutive Liver Resections (2021)

Diaphragmatic hernia (DH) after a liver resection (LR) is an uncommon but potentially severe complication. In this retrospective study, we aim to share our experience with DH in our hepatic surgery center. We retrospectively analyzed 3107 patients who underwent a liver resection between January 2012 and September 2019. The diagnosis of DH was based on clinical examination and radiological imaging and confirmed by intraoperative findings during surgical repair. Five out of 3107 (0.16%) patients after LR developed DH. Especially, all five DH patients had a major right-sided LR before (<i>n</i> = 716, 0.7%). The mean time interval between initial LR and occurrence of DH was 30 months (range 15 to 44 months). DH exclusively occurred after a right or extended right hepatectomy. Two patients underwent emergency surgery, three were asymptomatic, and DH was diagnosed in follow-up imaging. Three of these five treated patients (60%) developed DH recurrence: two of three (67%) patients after suture repair alone and the only patient after suture repair in combination with an absorbable mesh. The patient who was treated with a composite mesh implant did not show any signs of DH recurrence after 52 months of follow-up. In patients who develop DH after liver surgery, a mesh augmentation with nonresorbable material is generally recommended. In order to diagnose these patients in an early state, we recommend that special attention be paid and a prompt and targeted diagnostic examination of patients with abdominal complaints after right-sided liver resections take place.
Modeling millimeter wave tropospheric attenuations for UAS and terrestrial aviation communications (2018)

The prevalence of unmanned aircraft systems (UAS) brings strict demands on reliable communication links for control and non-payload communication (CNPC). Millimeter wave (mmWave) links for UAS, and also for various airport links, are seeing new interest for future applications, in part due to the extremely large available bandwidths at these frequencies. In these bands, attenuation must be accurately quantified to ensure appropriate link design for reliability. Tropospheric attenuation is modeled statistically, and the most widely used model comes from the International Telecommunications Union (ITU). The ITU model relies on climate data and averages, and although it can account for variabilities, little has been reported on extreme conditions and use of regional weather data. In this paper, we investigate tropospheric attenuation in three potential mmWave bands (30, 60, and 90 GHz) for short range aviation links. Results are based upon the ITU-R time series model from Recommendations P.530 and P.1853 for link distances from 20 m to 5 km at three representative climatic locations: Cleveland, OH, Columbia, SC, and Miami, FL. Worst month attenuation variability analysis results are provided to illustrate the severity of tropospheric attenuation in these mmWave bands.
Single-input Multiple-output Multi-carrier Wireless Indoor Direction Finding in a Compact Multipath Scenario Using 2.4 GHz ISM Band2 (2019)

Super-resolution direction of arrival (DoA) estimation of impinging signals from a line of sight (LOS) source and multiple point scatterers at the 2.4 GHz ISM band is considered within a compact area. The channel is partially frequency flat in the interested range and all the impinging signals due to the point scatterers are correlated, which introduces the necessity of algorithms for decorrelation of signals. This paper introduces a frequency domain decorrelation scheme for the DoA estimation of a LOS source and point scatterers, which constraints a particular structure on the receiver antenna. The limitation in terms of resolution is demonstrated with respect to the coherence bandwidth of the channel for distinct cases of point scatterer locations with respect to the LOS source.
