MobileFaceNets: Efficient CNNs for Accurate Real-Time Face Verification on Mobile Devices (2018)

We present a class of extremely efficient CNN models, MobileFaceNets, which use less than 1 million parameters and are specifically tailored for high-accuracy real-time face verification on mobile and embedded devices. We first make a simple analysis on the weakness of common mobile networks for face verification. The weakness has been well overcome by our specifically designed MobileFaceNets. Under the same experimental conditions, our MobileFaceNets achieve significantly superior accuracy as well as more than 2 times actual speedup over MobileNetV2. After trained by ArcFace loss on the refined MS-Celeb-1M, our single MobileFaceNet of 4.0MB size achieves 99.55% accuracy on LFW and 92.59% TAR@FAR1e-6 on MegaFace, which is even comparable to state-of-the-art big CNN models of hundreds MB size. The fastest one of MobileFaceNets has an actual inference time of 18 milliseconds on a mobile phone. For face verification, MobileFaceNets achieve significantly improved efficiency over previous state-of-the-art mobile CNNs.
Functional validation of the carbon dioxide receptor genes in <i>Aedes aegypti</i> mosquitoes using RNA interference (2011)

Carbon dioxide (CO(2)) is an important long-range chemosensory cue used by blood-feeding female mosquitoes to find their hosts. The CO(2) receptor in Drosophila melanogaster was previously determined to be a heterodimer comprised of two gustatory receptor (Gr) proteins, DmGr21a and DmGr63a. In the mosquito Aedes aegypti, two putative orthologous genes, AaGr1 and AaGr3, were identified in the genome database, along with an apparent paralogue of AaGr1, AaGr2. In this study, RNA interference (RNAi)-mediated gene knockdown of either AaGr1 or AaGr3 resulted in a loss of CO(2) sensitivity in both male and female mosquitoes, suggesting that these two proteins, like the Drosophila orthologues, function as a heterodimer. RNAi-mediated knockdown of AaGr2 expression had no impact on CO(2) reception. All three Gr genes were expressed in the maxillary palps of both Ae. aegypti and the West Nile virus vector mosquito, Culex pipiens quinquefasciatus. Interestingly, expression of the two CO(2) receptor genes was not equivalent in the two sexes and the implications of differential sex expression of the CO(2) receptor in different species are discussed. The functional identification of the CO(2) receptor in a mosquito could prove invaluable in the strategic design of compounds that disrupt the mosquito's ability to find hosts.
Putting the 'I' in 'team': an ego-centric approach to cooperative localization (2004)

This paper describes a cooperative method for relative localization of mobile robot teams; that is, it describes a method whereby every robot in the team can estimate the pose of every other robot, relative to itself. This robot does not require the use of GPS, landmarks, or maps of any kind; instead, robots make direct measurement of the relative pose of nearby robots, and broadcast this information to the team as a whole. Each robot processes this information independently to generate ego-centric estimate for the pose of other robots. Our method uses Bayesian formalism with a particle filter implementation, and is, as a consequence, very robust. It is also completely distributed, yet requires relatively little communication between robots. This paper describes the basic ego-centric formalism, sketches the implementation, and presents experimental results obtained using a team of four mobile robots.
Multi-Objective Optimization of a Turbofan for an Advanced, Single-Aisle Transport (2011)

Considerable interest surrounds the design of the next generation of single-aisle commercial transports in the Boeing 737 and Airbus A320 class. Aircraft designers will depend on advanced, next-generation turbofan engines to power these airplanes. The focus of this study is to apply single- and multi-objective optimization algorithms to the conceptual design of ultrahigh bypass turbofan engines for this class of aircraft, using NASA s Subsonic Fixed Wing Project metrics as multidisciplinary objectives for optimization. The independent design variables investigated include three continuous variables: sea level static thrust, wing reference area, and aerodynamic design point fan pressure ratio, and four discrete variables: overall pressure ratio, fan drive system architecture (i.e., direct- or gear-driven), bypass nozzle architecture (i.e., fixed- or variable geometry), and the high- and low-pressure compressor work split. Ramp weight, fuel burn, noise, and emissions are the parameters treated as dependent objective functions. These optimized solutions provide insight to the ultrahigh bypass engine design process and provide information to NASA program management to help guide its technology development efforts.
Co-Cr perpendicular magnetic recording tape by vacuum deposition (1984)

The relation between the incident angle and the crystallographic orientation of a vacuum deposited Co-Cr film is discussed. Also presented are the magnetic properties and the orientation of both a Ni-Fe underlayer and the Co-Cr film for the double layer medium, and the experimental results about the composition distribution in the co-cr film. The films were deposited on a transporting polymer substrate by continuous vacuum deposition. It is found that the orientation of the Co-Cr film is determined only by the incident angle at the initial point of the film formation, and that deposition efficiency more than 50% can be achieved easily. A double layer medium with Ti film under the Ni-Fe film (Co-Cr/Ni-Fe/Ti medium), which is suitable for perpendicular magnetic recording, is produced by vacuum deposition. Auger depth profile in radial direction of the column of the Co-Cr film shows directly that there is Cr segregation near the columnar grain boundaries.
Synthesis, Crystal Structure, and Biological Activities of 2-Cyanoacrylates Containing Furan or Tetrahydrofuran Moieties (2007)

A series of novel cyanoacrylates containing furan or tetrahydrofuran moieties were synthesized, and their structures were characterized by 1H NMR, elemental analysis, and single-crystal X-ray diffraction analysis. The herbicidal, plant growth regulatory, fungicidal, and antiviral activities of these cyanoacrylates were evaluated. The results of herbicidal activities showed that most of these cyanoacrylates exhibited higher herbicidal activities against dicotyledonous weeds than monocotyl-edonous weeds, and the compounds containing the tetrahydrofuran moiety gave higher herbicidal activities than corresponding furan analogues; (Z)-ethoxyethyl 2-cyano-3-isopropyl-3-(tetrahydrofuran-3-yl)methaneaminoacrylate showed excellent herbicidal activities against amaranth pigweed in postemergence treatment at a dose of 375 g/ha. At the same time, these cyanoacrylates had interesting plant growth regulatory activities, and some compounds stimulated radicle growth of cucumber, whereas some compounds had an inhibitory effect. These cyanoacrylates showed fungicidal activities as well.
Depth of Field (2009)

It is, of course, well known that if we focus a camera on an object at some definite distance from the camera lens, there will be a finite range of distances in front of and beyond the focused object in which everything appears acceptably in focus, while outside that range everything becomes progressively more blurred at increasing distances from the plane of best focus. The actual extent of this range of acceptably sharp definition depends mainly on the distance of the subject from the lens, the aperture of the lens, and on the manner in which we look at the final print, but it also depends to some extent on the type of subject being photographed, the resolving power of the film and paper emulsions, and the aberrations of the camera lens. However, for the sake of simplicity, the following discussion will be based on the assumption that we are using grainless film and aberration-free lenses, and we shall end with a few remarks on the effects of these neglected factors in actual practice. For ordinary fairly distant objects, the depth of field of most cameras is generally adequate, provided that we take care to focus the lens on the subject of principal interest. In a portrait this is generally the front of the face; failure to focus correctly in such a case may be artistically disastrous. However, when we have occasion to focus a lens down to one or two feet, we are surprised to find how little depth there is, even at small apertures. For example, a 2-inch lens at fâ8 when focused on objects at 12 inches distance has a depth of field of about half an inch in front of and beyond the focused distance. A small depth of field is sometimes very useful, for instance, as a means of eliminating an unwanted background (Fig. 5.1).
Continuous Assessment of Cerebral Autoregulation With Near-Infrared Spectroscopy in Adults After Subarachnoid Hemorrhage (2010)

Near-infrared spectroscopy can be used to continuously assess cerebral autoregulation in adults after subarachnoid hemorrhage.
Multiple effects of mutation on expression of alternative cell surface protein genes in Tetrahymena thermophila. (1992)

Genes at the SerH locus of the ciliated protist Tetrahymena thermophila specify the major (H) surface protein on cells grown at 20-36 degrees. Alternative proteins L, T, S and I are expressed under different conditions of temperature and culture media. Mutants unable to express SerH genes were examined for expression of these proteins, also called immobilization or i-antigens, at both H and non-H conditions. In all instances, one or more i-antigens were expressed in the absence of H, and, in most instances, expression of i-antigens under non-H conditions was also affected. Examples of the latter include both the continued expression of H-replacement antigens and the inability to express certain other i-antigens. Such multiple effects were observed in mutants with trans-acting (rseA, rseB, rseC, RseD) and cis-acting (H1-1 and H1-2) mutations, but not in mutants in which SerH is affected developmentally (B2092, B2101, B2103, B2107). These interactions suggest that the wild-type genes identified by mutation exert both positive and negative effects in the regulation of i-antigen gene expression.
Utilising paediatric massage in an intensive care unit (PICU) in Saudi Arabia. (2000)

In this detailed case study of a very sick baby in a modern technological hospital, nursing staff and parents joined forces to implement and monitor a fully coordinated massage program in response to possible ICU psychosis. Positive results indicate that massage enhances the delivery of truly holistic care.
Inherent optical properties of Jerlov water types (2015)

The diffuse attenuation coefficient K<sub>d</sub>(λ) was first expressed in terms of the inherent optical properties (IOPs) of water according to well-established empirical bio-optical models. Boltzmann simulated annealing was then used to find the best sets of IOPs to fit K<sub>d</sub>(λ) spectra to the reference spectra Kd0(λ) that define the Jerlov water types. Absorption a(λ) and scattering b(λ) coefficients were thus obtained for all Jerlov water types over the wavelength range 300-700 nm. The chlorophyll concentrations corresponding to the Jerlov water types were also obtained via bio-optical models. The result is a self-consistent set of spectral IOPs, chlorophyll concentrations, and Jerlov water types useful for a variety of underwater optical communications and remote sensing applications.
Effect of the growth hormone-releasing hormone [GHRH(1-44)NH2] on IL-6 and IL-8 secretion from human peripheral blood mononuclear cells in vitro. (2005)

Our results demonstrate that GHRH in vitro modulates IL-6 secretion from the human peripheral blood mononuclear cells, without any significant effect on IL-8 secretion.
Neutrophil dynamics in the blood and milk of crossbred cows naturally infected with Staphylococcus aureus (2015)

The study indicated a positive correlation between delayed neutrophil apoptosis, persistent staying of neutrophils at the site of infection along with formation of NETs as the strategies to fight against the pathogens in the udder during Staphylococcal mastitis. The study forms a strong base for future molecular research in terms of neutrophil recruitment and neutrophil removal from the site of infection.
Spatiotemporal expression of histone acetyltransferases, p300 and CBP, in developing embryonic hearts (2009)

Histone acetyltransferases (HATs), p300 and cAMP response element binding protein (CREB)-binding protein (CBP) are two structurally related transcriptional co-activators that activate expression of many eukaryotic genes involved in cellular growth and signaling, muscle differentiation and embryogenesis. However, whether these proteins play important and different roles in mouse cardiogenesis is not clear. Here, we investigate the protein distributions and mRNA expression of the two HATs in embryonic and adult mouse heart during normal heart development by using immunohistochemical and RT-PCR techniques. The data from immunohistochemical experiments revealed that p300 was extensively present in nearly every region of the hearts from embryonic stages to the adulthood. However, no CBP expression was detected in embryonic hearts at day E7.5. CBP expression appeared at the later stages, and the distribution of CBP was less than that of p300. In the developmental hearts after E10.5, both for p300 and CBP, the mRNA expression levels reached a peak on day E10.5, and then were gradually decreased afterwards. These results reveal that both p300 and CBP are related to embryonic heart development. The dynamic expression patterns of these two enzymes during mouse heart development indicate that they may play an important role on heart development. However, there is a difference in spatiotemporal expression patterns between these two enzymes during heart development. The expression of p300 is earlier and more predominate, suggesting that p300 may play a more important role in embryonic heart development especially during cardiac precursor cell induction and interventricular septum formation.
Rapid and robust detection of branch points from wave-front gradients (1999)

We discuss a technique that permits branch points in the phase function to be localized in real-time adaptive-optics systems and that is unambiguous and robust in the presence of noise.
Electromigration-induced failure of GaNmulti-quantum well light emitting diode (2000)

The reliability characteristics of a multi-quantum well (MQW) GaN/InGaN light emitting diode (LED) under various stress current densities have been investigated. Based on the contact electromigration failure model of a silicon device, the lifetime of the LED device under normal operating current condition can be obtained from the relation tf = C/In.
<sup>1</sup>H MR spectroscopy using TE averaged PRESS: A more sensitive technique to detect neurodegeneration associated with Alzheimer's disease (2005)

A sensitive proton magnetic resonance spectroscopy ((1)H MRS) acquisition scheme that is capable of discriminating between normal controls and a group of patients with early Alzheimer's disease (AD) is presented. The performance of this newly developed method, TE averaged PRESS (PRESS-J), in detecting neurodegeneration associated with early AD is compared with that of short echo time (TE) PRESS. A stepwise discriminant function analysis is used to construct discriminant functions for both pulse sequences. These functions are each composed of a single predictor: the N-acetyl aspartate (NAA)/creatine (Cr) ratio for PRESS-J, and the NAA/myoInositol (mI) ratio for PRESS. We observed lower P-values, higher areas under the receiver operating characteristic curves, and higher sensitivity at a given specificity for the PRESS-J discriminating function in comparison with the PRESS discriminating function. The higher sensitivity of PRESS-J is due to decreased variability when the singlets are fit in the spectra. This increased sensitivity enables new MR applications and, among other benefits, allows for smaller group sizes in drug trials, which can significantly reduce the cost of such trials.
Asporogenous <i>Bacillus thuringiensis</i> Mutant Producing High Yields of δ-Endotoxin (1982)

An asporogenous Bacillus thuringiensis subsp. kurstaki strain IK mutant, strain 290-1, which produced high yields of delta-endotoxin, was obtained by ethyl methane sulfonate treatment of a spore suspension. The mutant strain produced about the same amount of delta-endotoxin as that produced by the parent strain, but 10 to 10 cells did not form any detectable dormant spores.
A unified OLAP/OLTP big data processing framework in telecom industry (2016)

This paper studies the system performance of SQL-on-Hadoop technology and MPP technology in an OLAP and OLTP mixed scenario, which is becoming the most common big data application scenario in telecom industry. Until recently, most SQL-on-Hadoop systems only focus on the speed of data analysis but overlook the support for transactions. MPP columnar databases, on the other hand, are able to deal with both analytical and transactional tasks, but tend to have poor transactional performance due to the column-store mechanism. By adopting proper optimization methods, it is possible to increase transactional performance of MPP columnar databases. Finally, a unified data processing framework is proposed for a better support of hybrid OLAP/OLTP big data applications.
Chimeric Antigen Receptor T-Cell Therapy for the Community Oncologist (2016)

The present report describes the current status of chimeric antigen receptor (CAR) T lymphocytes as an immunotherapy for patients with relapsed or refractory B-cell malignancies. CAR T cells targeting CD19, a protein expressed on many B-cell malignancies, typically induce high complete response rates in patients with B-cell leukemia or lymphoma who have very limited therapeutic options. Recent clinical trial results of CD19 CAR T-cell therapies and the management of CAR T-cell-associated adverse events are discussed. The present report will therefore inform physicians regarding the efficacy and safety of CAR T cells as a therapy for B-cell malignancies.
Electrothermal-Chemical Propulsion and Performance Limits for the 120-mm, M256 Cannon (1991)

Abstract : Electrothermal-chemical (ETC) propulsion and potential performance for the M256, 120-mm cannon are examined. The upper performance limit for this cannon is about 15 MJ of projectile muzzle energy. The study also indicates that the most effective use of electrical energy in ETC propulsion is pressure profile control. The addition of electrical energy simply to augment the total energy results in a low (<20%) transfer of energy to the projectile.
Solvent-assisted linker exchange (SALE) and post-assembly metallation in porphyrinic metal–organic framework materials (2012)

Using recently reported robust porphyrinic metal–organic framework (RPM) materials, we have examined the systematic exchange of pillaring linkers/struts as a means of accessing new versions of these materials. Dipyridyl-porphyrin Zn(II) (Zn-dipy) struts were successfully replaced by M2-dipy (M2 = 2H(+), Al(III), Sn(IV)), forming crystalline solid solutions of Zn(Zn1−xMx)-RPM in variable ratios. In addition, post-synthetic metallation was demonstrated using Zn2H-RPM, again with retention of crystallinity. We examined catalytic activity for an epoxide ring-opening reaction with a series of ZnM2-RPMs. The catalytic activity depends strongly on the identity of the metal ion present in the dipyridyl-porphyrin unit.
A Hybrid Channel Assignment Scheme in Large-Scale, Cellular-Structured Mobile Communication Systems (1978)

This paper considers the problem of channel assignment in mobile communication systems, where the service area is divided in hexagonal cells. In particular, a Hybrid Channel Assignment Scheme is studied and certain results are obtained using GPSS simulation of a model 40-cell system.
Multi-Granulin Domain Peptides Bind to Pro-Cathepsin D and Stimulate Its Enzymatic Activity More Effectively Than Progranulin <i>in Vitro</i> (2019)

Progranulin (PGRN) is an evolutionarily conserved glycoprotein associated with several disease states, including neurodegeneration, cancer, and autoimmune disorders. This protein has recently been implicated in the regulation of lysosome function, whereby PGRN may bind to and promote the maturation and activity of the aspartyl protease cathepsin D (proCTSD, inactive precursor; matCTSD, mature, enzymatically active form). As the full-length PGRN protein can be cleaved into smaller peptides, called granulins, we assessed the function of these granulin peptides in binding to proCTSD and stimulating matCTSD enzyme activity in vitro. Here, we report that full-length PGRN and multi-granulin domain peptides bound to proCTSD with low to submicromolar binding affinities. This binding promoted proCTSD destabilization, the magnitude of which was greater for multi-granulin domain peptides than for full-length PGRN. Such destabilization correlated with enhanced matCTSD activity at acidic pH. The presence and function of multi-granulin domain peptides have typically been overlooked in previous studies. This work provides the first in vitro quantification of their binding and activity on proCTSD. Our study highlights the significance of multi-granulin domain peptides in the regulation of proCTSD maturation and enzymatic activity and suggests that attention to PGRN processing will be essential for the future understanding of the molecular mechanisms leading to neurodegenerative disease states with loss-of-function mutations in PGRN.
Size distribution of casein micelles during milk coagulation (1985)

Electron microscopy was employed to study the size distribution and the surface to volume ratios of casein micelles in coagulum from raw milk, heated milk and milk enriched with calcium chloride before the heating process. The particles size distribution of milk protein was changed by heating resulting in an increase in the free subunits of smaller size and the surface to volume ratios. On the other hand the clotting time was prolonged. Depression in the clotting time and surface to volume ratios was occurred by adding calcium chloride to the milk before the heating process to retard the formation of complex between the whey protein and milk casein.
