description: Conventionally for observable $n-{\bar n}$ oscillation through Pati-Salam intermediate gauge symmetry in $SO(10)$, the canonical seesaw mechanism is also constrained by $M_R \sim M_C \le 10^6$ GeV which yields light neutrino masses much larger than the neutrino oscillation data. Recently, this difficulty has been evaded via inverse seesaw mechanism, but with proton lifetime far beyond the experimentally accessible limits. In the present work, adopting the view that we may have only a TeV scale $Z^{\prime}$ gauge boson, we show how a class of non-SUSY $SO(10)$ models allow experimentally verifiable proton lifetime and the new contributions to neutrinoless double beta decay in the $W_L-W_L$ channel, lepton flavor violating branching ratios, observable $n-{\bar n}$ oscillation, and lepto-quark gauge boson mediated rare kaon decays. The occurrence of Pati-Salam gauge symmetry with unbroken D-parity and two gauge couplings at the highest intermediate scale guarantees precision unification in such models. This symmetry also ensures vanishing GUT threshold uncertainy on $\sin^2θ_W$ or on the highest intermediate scale. Although the proton lifetime prediction is brought closer to the ongoing search limits with GUT threshold effects in the minimal model, no such effects are needed in a non-minimal model. We derive a new analytic expression for the $0νββ$ decay half-life and show how the existing experimental limits impose the lower bound on the lightest of the three heavy sterile neutrino masses, $M_{S_1}\ge 14\pm 4$ GeV. We also derive a new lower bound on the lepto-quark gauge boson mass mediating rare kaon decay, $M_{\rm lepto} \ge (1.53{\pm 0.06})\times 10^6$ GeV. The $n-{\bar n}$ mixing times are predicted in the range$τ_{n-{\bar n}}\simeq 10^8-10^{13}$ sec.

description: We propose a new testing procedure for detecting localized departures from monotonicity of a signal embedded in white noise. In fact, we perform simultaneously several tests that aim at detecting departures from concavity for the integrated signal over various intervals of different sizes and localizations. Each of these local tests relies on estimating the distance between the restriction of the integrated signal to some interval and its least concave majorant. Our test can be easily implemented and is proved to achieve the optimal uniform separation rate simultaneously for a wide range of Hölderian alternatives. Moreover, we show how this test can be extended to a Gaussian regression framework with unknown variance. A simulation study confirms the good performance of our procedure in practice.

description: This study aimed to assess the current status of the Philippine Normal University North LuzonCampus Library and Resource Center in terms of its quality of resources, services and facilities. Hence, theextent of library services as perceived by the school administrators, faculty and students was determined, inaddition, comparative analysis was also conducted to identify difference in the perceptions of libraryservices among school administrators, faculty members, and students at the Philippine Normal UniversityNorth Luzon Campus Library and Resource Center. In terms of the perception of the respondents regardingthe status of services offered by the institution’s library and resource center, a grand mean of 3.45 and anSD of 0.42 were computed which resulted to a verbal interpretation of Agree. Further analysis shows thatboth library resources and library services garnered the similar mean of 3.47 signifying the adequacy of bothareas as perceived by the respondents. Meanwhile, library facilities garnered a lower mean of 3.42 indicatingthe need to improve on this area. In terms of respondents’ satisfaction levels of the services provided, agrand mean of 3.47 and an SD of 0.45 were computed which corresponded to a verbal interpretation of‘satisfied’. Moreover, both library resources and library services received a mean of 3.47 which signifiesthat the respondents perceive these areas to be equally satisfying in fulfilling their needs. In addition to theaforementioned, statistically significant relationship between the respondents’ awareness and attitudetowards the PNU-NL Library resources, services and facilities was also found. Moreover, there is nosignificant difference in the perceived satisfaction of the respondents with the PNU- NL library resources,services, and facilities among administrators, faculty and students. These results served as the basis for adevelopment plan to be proposed for the enhancement of the Philippine Normal University North LuzonCampus Library and Resource Center.

description: Non-alcoholic beers have seen steady growth in recent years and are attracting customer interest. At the same time, consumer demand for non-alcoholic beers is rising. While wort-like flavors are often criticized in beer and also regarded as off-flavors, there is growing demand for beer flavor diversification. The latest research results prove that certain non-Saccharomyces yeast species can produce distinctive fruity flavor profiles during wort fermentation. In this study, 15 different yeast strains were evaluated for their suitability to produce novel flavor profiles during fermentation in wort from malt extract while being tested for their ability to produce less than 0.5% (v/v) ethanol. The yeast strains were therefore analyzed for their sugar utilization and were compared with the maltose-negative reference yeast strain Saccharomycodes ludwigii TUM SL17. Following the fermentation experiments, the beers were analyzed for secondary metabolites and ethanol content before being tasted by trained assessors. The results reveal that all 15 yeasts are suitable for the production of non-alcoholic beers based on their sugar utilization. Particularly promising flavors were produced by three yeast strains of the species Cyberlindnera saturnus, which were reminiscent of cool mint sweets, pear, and banana. Two further yeasts of the species Kluyveromyces marxianus and Saccharomycopsis fibuligera also produced a wide range of pleasant fruity flavors. Although the secondary metabolites were mostly below the odor thresholds based on regular alcoholic beers, this study reveals that the thresholds in non-alcoholic beers can be classified as significantly lower.

description: The San Jose Hills, located in the eastern part of Los Angeles County, California, occupy a rectangular block of some 40 square miles in area, the center of which is 30 miles to the east of Los Angeles (Plate I). Although a separate physiographic unit, the region may be described as that portion of the Puente Hills lying north of the San Jose Wash (Plate II). The area mapped extends from Pomona southwest to Puente, a distance of 11 miles. It may readily be reached from either town, both of which lie on the main line of the Southern Pacific Railroad and on U.S. Highway Number 99, known locally as the Valley Boulevard. All parts of the area are readily accessible, for it is cut by roads in the eastern, central, and western portions.

description: В процессе многолетних исследований Рождественского городища, известного по письменным источникам как городок Афкула, получены новые данные об особенностях жилищ: от технологии возведения самих построек до специфики обустройства интерьера, прослежены хронологические изменения в конструкции жилищ, обусловленные сменой археологических культур. Все жилища построены в каркасно-столбовой технике с закладкой поперечных бревен или плах как в пазы стояков, так и между ними. В основании двускатной кровли находились опорные столбы, установленные в 1-3 ряда вдоль условной оси жилищ. Основным материалом для строительства домов служили бревно-кругляк и тесаный брус сечением около 20 см. Технику сооружения деталей интерьера и малых архитектурных форм тоже можно назвать каркасно-столбовой, но здесь основу составляли тонкие (до 10 см в диаметре) колья, вбитые в грунт. Жилища представляли собой прочные долговременные постройки, просторные и вполне комфортно обустроенные, что не соотносится с прежними представлениями о средневековом жилище как об «утепленном шалаше». Данные, полученные при исследованиях восточной части площадки городища, позволяют предполагать, что оно имело радиальную планировку, при которой улицы веером расходились от наиболее высокой части городища в сторону обрыва к р. Обвы, при этом плотность застройки была очень высока. Такая планировка типична для многих средневековых городов.

description: We theoretically investigate collective modes of a one-dimensional (1D) interacting Bose gas in harmonic traps at finite temperatures, by using a variational approach and local density approximation. We find that the temperature dependence of collective mode frequencies is notably different in the weakly and strongly interacting regimes. Therefore, the experimental measurement of collective modes could provide a sensitive probe for different quantum phases of a 1D trapped Bose gas, realized by tuning the interatomic interaction strength and temperature. Our prediction on the temperature dependence of the breathing mode frequency is in good qualitative agreement with an earlier experimental measurement for a weakly interacting 1D Bose gas of rubidium-87 atoms in harmonic traps [Moritz et al., Phys. Rev. Lett. 91, 250402 (2003)].

We use the analytical solution of Bisnovatyi-Kogan and Murzina (1995) for the spherically symmetric relativistic expansion. The light-curves and the spectra from transparency of an electron-positron-photon plasma are obtained. We compare our results with the work of Goodman (1986).

The Stratigraphy and Foraminiferal Fauna of the Santa Susana Formation

description: The Santa Susana formation on the north side of the Simi Valley, Ventura County, California consists of 2360 feet of marine sediments. Macro-fossils found by previous workers indicate that the formation represents the the Meganos Eocene. As these fossils came from the upper 300 feet of the formation, nothing was known concerning the correlation of the remainder of the section.

Abundant and well preserved foraminifera have been found by the writer through the entire section, with the exception of the lower 275 feet. These micro-fossils indicate that the lower portion of the Santa Susana is also of Meganos age.

The fauna has been found to consist of three distinct faunules which form the basis for the same number of zones. The validity of this zoning must be tested by checking the present section with others in this and other localities. This has not as yet been possible.

The foraminifera indicate that the Santa Susana formation represents two stages of the Gulf Coast Eocene succession, the upper Midway and the overlying Wilcox. Approximately fifty per cent of the total species present in the lower two zones are present in the upper Midway of Texas. The correlation of the upper zone with the Wilcox of Alabama is less certain.

Six lithologic members are present in the section which show that the beds became gradually finer from the basal conglomerate upward into the middle shale member and then becomes coarser from the top of the shale member upward. These lithologic members do not correspond with the faunal divisions.

description: The singularities associated with QCD factorization in the collinear limit are key ingredients for high-precision theoretical predictions in particle physics. They govern the collinear behaviour of scattering amplitudes, as well as the perturbative energy evolution of parton densities (PDFs) and fragmentation functions (FFs). In this talk, we present the computation of multiple collinear and higher-order QCD splittings with massive partons. Our results are highly-relevant for the consistent introduction of mass effects in the subtraction formalism and PDF/FF evolution.

description: This work is focused on the study of the distribution in the CPPS of passive and star-forming galaxy populations and also, the intense and quiescent star-forming populations for a set of 9 nearby z<0.05 galaxy clusters. Furthermore, we compare the CPPS distribution of the passive galaxy population with the accreted halo population of a set of 28 simulated clusters and the star-forming population with the non-accreted population. We consider various cluster accretion epochs and accretion radii where it is assumed that star formation in galaxies becomes quenched, in order to segregate the accreted population from the non-accreted population. Just applying this segregation in simulations, we get a qualitative agreement between the CPPS distributions of the passive and the accreted populations and also between the star-forming and the non-accreted populations. The uncertainty in cluster centering strongly affects the pronounced cuspy profiles of the projected density and also, it can explain the main difference (i.e. inner slope) between the CPPS distribution of passive and accreted populations. The CPPS density of star-forming galaxies and the intensity of ram-pressure stripping present an opposite trend throughout the CPPS. This implies that ram-pressure stripping significantly contributes to modulate the observed CPPS distribution of star-forming galaxies inside and around cluster virial regions. The significant fraction of star-forming galaxies at the projected center of clusters are mainly those galaxies with low l-o-s velocities and they can be mainly identified as those galaxies with a remaining star formation activity (quiescent star-forming galaxies) inside the physical virial region or, in a lower degree, as galaxy interlopers i.e. outside the physical virial region.(abridged)

Prospective Memory and Social Functioning in Midlife and Old Age

Publisher: name: OSF Registries

Subjects: subject: Social and Behavioral Sciences

description: Prospective memory refers to the ability to remember to do something in the future, and it is essential for managing everyday life demands. Prospective memory plays a crucial role in social activities, such as keeping appointments, and it becomes increasingly important as we age. However, few studies have specifically examined the relationship between prospective memory and social functioning using a longitudinal design. This is significant because a decline in prospective memory performance could have negative consequences on social functioning (e.g., forgetting a meeting with a friend), while a stimulating social environment could potentially protect older adults from cognitive decline. This study aims to investigate how PM and social functioning affect each other in a group of aging participants.

description: We investigate the possibility of guiding stable ultraslow weak-light bullets by using Airy beams in a cold, lifetime-broadened four-level atomic system via electromagnetically induced transparency (EIT). We show that under EIT condition the light bullet with ultraslow propagating velocity and extremely low generation power formed by the balance between diffraction and nonlinearity in the probe field can be not only stabilized but also steered by the assisted field. In particular, when the assisted field is taken to be an Airy beam, the light bullet can be trapped into the main lobe of the Airy beam, propagate ultraslowly in longitudinal direction, accelerate in transverse directions, and move along a parabolic trajectory. We further show that the light bullet can bypass an obstacle when guided by two sequential Airy beams. A technique for generating ultraslow helical weak-light bullets is also proposed.

description: At the suggestion of Dr. Bulwalda of the Institute Staff, the mapping and investigation of this hitherto little known section of the Mojave Desert was undertaken. It had been known for some time that there were marine beds lying in the extreme western corner of the desert, their age relation however, had been but tentatively determined and their areal extend and structural relations were unknown. U.S. Geol. Survey Water Supply Paper 278 by Harry R. Johnson is the only paper known to the writer which deals with this area.

In the present study, an effort is made to map the areal geology as carefully as possible in the short time available and to determine the age and structural relations of the marine formation.

description: The spectral and scattering theory for 1-dimensional Dirac operators with mass $m$ and with zero-range interactions are fully investigated. Explicit expressions for the wave operators and for the scattering operator are provided. These new formulae take place in a representation which links, in a suitable way, the energies $-\infty$ and $+\infty$, and which emphasizes the role of $\pm m$. Finally, a topological version of Levinson's theorem is deduced, with the threshold effects at $\pm m$ automatically taken into account.

description: The region to be considered in this report is in Los Angeles County, Calif. and is included in the Lang Quadrangle surveyed in 1929 with a scale of 1:24,000 and a contour interval of 5 and 25 feet. The region is also shown on the San Fernando Quadrangle with a scale of 1:62,500 and a contour interval of 50 feet. The area mapped is included between two canyons, Pole Canyon immediately south of Lang, and Little Bear Canyon about a mile and three quarters
east of Lang.

The area may be reached on the Sierra Highway by turning east into Soledad Canyon just before the Sierra Highway enters Mint Canyon, a distance of about thirty-eight miles from Los Angeles. Lang is about five miles east of the junction of Mint Canyon with Soledad Canyon. The area may be reached by the Southern Pacific Lines which has a siding at Lang.

The problem was undertaken in partial fulfillment of the
requirements for the degree of Master of Science at the Calif. Institute of Technology. The work has been done under the direction and guidance of Dr. Ian Campbell, Associate Professor of Petrology at the Calif. Institute.

description: Within recent years there has been a renewed interest among geologists in the field of sedimentary petrography. This interest has been rewarded by the accumulation of much new and interesting data. Careful studies of the textures and mineral compositions of formations have yielded important clues regarding climatic and geographic conditions during ancient times. These studies have made it possible in some cases to correlate unfossiliferous sediments.

In this paper the writer is chiefly concerned with the heavy minerals of the Modelo sediments with the view to learning what lateral and vertical variations may occur in the mineral composition of a formation over a small area – a matter which is of great significance if the minerals are to be used as criteria for correlation – and to learn something of the paleogeography during the deposition of the sediments in question.

Although heavy minerals have served as the key to many perplexing problems, they have not been universally used with success. Many of the failures however, are directly attributable to unreasonable expectations on the part of investigators.

description: We investigate a generalized Dicke model by introducing two interacting spin ensembles coupled with a single-mode bosonic field. Apart from the normal to superradiant phase transition induced by the strong spin-boson coupling, interactions between the two spin ensembles enrich the phase diagram by introducing ferromagnetic, antiferromagnetic and paramagnetic phases. The mean-field approach reveals a phase diagram comprising three phases: paramagnetic-normal phase, ferromagnetic-superradiant phase, and antiferromagnetic-normal phase. Ferromagnetic spin-spin interaction can significantly reduce the required spin-boson coupling strength to observe the superradiant phase, where the macroscopic excitation of the bosonic field occurs. Conversely, antiferromagnetic spin-spin interaction can strongly suppress the superradiant phase. To examine higher-order quantum effects beyond the mean-field contribution, we utilize the Holstein-Primakoff transformation, which converts the generalized Dicke model into three coupled harmonic oscillators in the thermodynamic limit. Near the critical point, we observe the close of the energy gap between the ground and the first excited states, the divergence of entanglement entropy and quantum fluctuation in certain quadrature. These observations further confirm the quantum phase transition and offer additional insights into critical behaviors.

description: Рассматриваются ранние укрепленные поселения Волжской Булгарии, которые возникли в X-XI вв. на территории этого государства. Письменные источники и археологические материалы позволяют проследить время появления и характер средневековых городищ в регионе Среднего Поволжья на первоначальном этапе развития булгарской городской культуры и государственности. Здесь рассматривается сложная картина развития градостроительства. Сюда входят как осознанный выбор места для будущих поселений, так и способы их защиты. Несмотря на небольшое количество известных на сегодняшний день памятников фортификации, мы имеем представление об основных типах оборонительных сооружений того времени. Их кажущаяся простота не должна вводить в заблуждение, так как для рассматриваемого хронологического периода они были достаточны. Основываясь на них, булгарская фортификация прошла затем быстрый путь развития от «простых» крепостных конструкций к более сложным. Это утверждение касается и самого градостроительства в целом.

description: Рассматриваются вопросы, связанные со становлением и развитием ювелирного дела волжских булгар. Этот процесс приходится на Х в. До 960-х гг. волжские булгары были в политическом отношении подчинены хазарам, а их территория входила в состав хазарского государства. Это подтверждается сведениями письменных источников Х в. Несомненно, были и экономические связи. Уточнить данное положение, используя археологические материалы, непросто. До середины Х в. у нас есть только предметы из языческих некрополей волжских булгар: Танкеевского и Тетюшского могильников, функционировавших в первой половине Х в. Поселения этого времени не обнаружены. Поэтому о характере булгарского ювелирного ремесла этого периода мы можем высказывать только предположения. Даже о том, что могли производить булгарские ювелиры в этот период самостоятельно, мы не имеем ясного представления, поскольку значительная часть изделий имеет широкое распространение на памятниках Восточной Европы в это время. Учитывая центры ювелирного производства у хазар, доля их продукции была достаточно существенной. Несмотря на то что через территорию волжских булгар в Х в. проходили значительные потоки серебряных монет из мусульманских стран Востока, и, очевидно, булгарские торговцы принимали участие в посреднических операциях, но, судя по археологическим данным, особого воздействия на развитие булгарской экономики до 960-980-х гг. они не оказали. Следы собственного ювелирного производства зафиксированы на II Билярском и I Измерском селищах не ранее 960-х гг. Они в основном связаны с изготовлением медных и бронзовых украшений поясного гарнитура, а также костюма. Разгром Хазарии и ее ремесленных центров ускорили развитие булгарского ювелирного дела. Начало массового производства серебряных и золотых украшений в Волжской Булгарии приходится на конец Х в. первую половину XI в.

description: Glioblastoma is a highly invasive brain tumor resulting in a mean survival of only 8 months even with aggressive treatment. Convection-enhanced delivery (CED) is an investigational therapy to treat glioblastoma that utilizes loco-regional drug delivery. However, standard CED has proven to result in inadequate drug volume dispersed (V [subscript d]) increasing the likelihood of tumor recurrence. This dissertation focuses on the refinement and design of the Convection-enhanced Thermo-therapy Catheter System (CETCS) and explores methods for further improving V [subscript d] utilizing the new drug delivery protocols made possible by CETCS. First, a new fiber optic microneedle device (FMD) fabrication method, solid fiber inside capillary (SFIC) FMD, and a modified fusion splicing (FS) method is presented with the goal of increasing light delivery efficiency. The modified FS FMD resulted in an increase in light transmission efficiency compared to previous prototypes. Next, we test the ability of constant flow rate, controlled catheter movement to increase V [subscript d] compared to stationary catheters in an agarose gel model. V [subscript d] for retraction and intermittent insertion was significantly higher than the stationary group. Following the results of the controlled catheter movement study, the value of constant pressure, controlled catheter movement was hypothesized. Constant pressure infusions were conducted with stationary, 0.25 mm/min, and a 0.5 mm/min catheters in agarose gel. The 0.25 mm/min and 0.5 mm/min retracting constant pressure catheters resulted in significantly larger V [subscript d] compared to any other group. In order to expand on these results, a computational framework for predicting V [subscript d], flow rate, and concentration gradients for pressure controlled and flow controlled infusions with controlled catheter movement was developed. Results indicated that movement of any kind appears to have marked advantage over a stationary catheter for both V [subscript d] and concentration distribution. Finally, the design for the CETCS hardware and software, excluding those of the CETCS MRI transmission system, is presented. The CETCS system has the ability to remotely operate 6 lasers, 6 syringe pumps, 6 individual microneedles, and the primary cannula of the arborizing catheter. Additionally, the software collects pressure sensor data, and the most recent revision has the capability of pressure control

description: We consider a nonlinear coupler with two Kerr-like oscillators mutually coupled by continuous linear interaction and excited by a series of ultra-short external pulses. We show that the system behaves as nonlinear quantum scissors. It evolves such a way that it can be treated as qubit-qubit system. We derive analytic formulas for the probabilities of the states involved in the system's evolution and show that they differ from those already discussed in the literature and corresponding to the continuously excited models. Moreover, for model discussed here, maximally entangled Bell states can be generated with high efficiency.

Антропоморфные изображения, имеющие давнюю традицию схематизированных изображений человека, в различных вариациях, как правило, носят гипотетический характер. Подвески, не несущие графически однозначной смысловой нагрузки начертаний (надписи и изображения), требуют анализа в длительной исторической ретроспективе. На сегодня нет четких оснований говорить, что антропоморфные подвески являются олицетворением бога Тенгре.

description: Besides superconductivity, copper-oxide high temperature superconductors are susceptible to other types of ordering. We use scanning tunneling microscopy and resonant elastic x-ray scattering measurements to establish the formation of charge ordering in the high-temperature superconductor Bi2Sr2CaCu2O8+x. Depending on the hole concentration, the charge ordering in this system occurs with the same period as those found in Y-based or La-based cuprates, and displays the analogous competition with superconductivity. These results indicate the similarity of charge organization competing with superconductivity across different families of cuprates. We observe this charge ordering to leave a distinct electron-hole asymmetric signature (and a broad resonance centered at +20 meV) in spectroscopic measurements, thereby indicating that it is likely related to the organization of holes in a doped Mott insulator.

description: Археологические исследования последних лет к западу, юго-западу от Соборной мечети Болгара позволили выявить металлургический комплекс, который соотносился с ранним периодом существования города (Х начало Х1 в.). В раскопах было зафиксировано четыре сыродутных металлургических горна подземного (тигельного) типа. Горны раннего Болгара имели схожую форму и устройство с сыродутными горнами лесостепного варианта салтовомаяцкой культуры. Площадка металлургического комплекса занимала западную периферию раннего Болгара. На площадке металлургического комплекса, кроме горнов, были зафиксированы участки, где производилось обогащение руды и ее дробление. Всего с таких участков было собрано более 200 кг руды, которая имела различную степень подготовки к плавке. Увеличение территории города и возведение новой оборонительной линии Х1-Х11 вв. приводит к смещению металлургического района на запад и юго-запад, где были выявлены горны иного типа устройства. В золотоордынский период на месте раннего металлургического комплекса развивается ремесленно-торговый район Болгара. Существование крупного металлургического комплекса на западной окраине Болгара Х начала Х1 в. позволяет утверждать, что экономическую основу раннего города составляла не только торговля, но и значительное по объему металлургическое производство.

description: We have investigated the Mn-site substitution effect in Nd$_{0.45}$Sr$_{0.55}$MnO$_3$ single crystal, which has an $A$-type layered antiferromagnetic ($A$-AFM) phase with the 3$d_{x^2-y^2}$-type orbital-order. Substitution of Fe or Ga for Mn-site suppresses both the $A$-AFM order and competing ferromagnetic (FM) correlation whereas Cr substitution suppresses only the $A$-AFM order but reactivates the underlying FM correlation via double-exchange mechanism along the AFM coupled $c$-direction. In Nd$_{0.45}$Sr$_{0.55}$Mn$_{0.95}$Cr$_{0.05}$O$_3$, the $A$-AFM state with the orbital-order is changed into the orbital-disordered three-dimensional FM metallic state by applying magnetic field of $μ_0 H = 12$ T, which is much smaller than that of the parent compound Nd$_{0.45}$Sr$_{0.55}$MnO$_3$.
